1. Planning and Analysis Phase
In this phase, the primary focus of the project team is to identify the information asset that need
protecting and to analyze the threats to those information.
2. Design In this phase, the project manager will consider all options. Will the information security
policy is needed? What are the benefits of developing information security policy? Will it add up the
cost of acquiring the system?
3. Implementation The implementation phase requires significant allocation of resources in
completing tasks such as conducting work flow and process analyses, creating the security levels for
application, harden server against network attack, training staff, and physically securing the server.
There are different strategies to ensure privacy and confidentiality of patient information. The first

Abstract
Rapid Application Development is Software Development technique and practices that involves
methods like iterative development and software prototyping. This is an object oriented technique to
system development that includes a method of development as well as software tools .These phases
can be re–cycle before organizing the automate system. RAD is a concept that products can be
established faster and of higher quality. These phases called Requirement Planning, Implementation
User design and construction. In rapid application development model, the user requirement for
designing the final product is defined using structured techniques and prototyping. The RAD model
involve of 5 steps which are business modelling, Process Modelling, Application Generation, Data
Modelling and Testing. . Comparing RAD Development Cycle with the traditional cycle, RAD is
high quality, lower cost and faster development. Analyzing, Developing, Designing, Document

Defining problems, objectives, and determining resources. It is important to also look at the
overarching problem with discussing the planning phase of the SDLC. Problems are going to be
established in the beginning so that there are clear pathways to find a solution. Most of the time the
project will be pre–equipped with the knowledge of the problems. It also is important to establish
objectives. Defining Objectives are the core of how the project flows smoothly. It is important to
understand that objectives need to be met to start to enable a new one. Many times projects will fail
due to skipping objectives. The results tend to make the IT professionals start completely over. It is
also important to determine resources that are available to use. Many times the specialists are able to
use previous diagrams, software, and other systems to complete the new project. Projects tend to fix
other systems that already have been set in place. These can be resources to complete the new
project. Figuring out how to create a better product. During the planning phase it is also a main goal
to determine how to fix the problem by having a better product. After planning, you have the option
of developing a new system, improving the current system, or leave the system as is. This ties in the
lines with understanding how to create a better product. Many times it is important to understand

The Theory Development Life Cycle Approach Essay
Honda is a well–known global manufacturer of automobiles and motorcycles. This means that its
contemporary information system is highly–organized for collection, organization, storage,
exchange, and communication of useful information. This efficient system helps support its business
operations, and decision–making. To facilitate the flow and take advantage of modern information
system, a number of development approaches and methodologies have been introduced. The
waterfall approach, iterative approach, and agile approach are some examples of them.
This report contains three main parts. The first part gives an introduction of two system
development approaches. The system development life cycle approach is recommended in Honda's
global information systems environment. The second part talks about two other methodologies. It
then discusses the potential deployment of structured systems analysis and design method in
Honda's global context. At the end of this report, an ethical–based risk assessment table is presented.
Some discussion is elaborated based on the table.
Introduction of systems development approaches
There are quite a few systems development approaches. In this report, systems development life
cycle (SDLC) and rapid application development (RAD) have been discussed.
Both methodologies can yield productive information systems if they are applied to appropriate
development projects and under the right circumstances. Since business needs and system
requirements

The Systems Development Life Cycle Essay
The systems development life cycle (SDLC), also referred to as the application development life–
cycle, is a term used in systems engineering, information systems and software engineering to
describe a process for planning, creating, testing, and deploying an information system. The systems
development life–cycle concept applies to a range of hardware and software configurations, as a
system can be composed of hardware only, software only, or a combination of both. PHASES: o 1
System investigation o 2 System analysis o 3 Design o 4 Environments o 5 Testing o 6 Training and
transition o 7 Operations and maintenance o 8 Evaluation The system development life cycle
framework provides a sequence of activities for system designers and developers to follow. It
consists of a set of steps or phases in which each phase of the SDLC uses the results of the previous
one. The SDLC adheres to important phases that are essential for developers, such as planning,
analysis, design, and implementation, and are explained in the section below. It includes evaluation
of present system, information gathering, feasibility and request approval. A number of SDLC
models have been created: waterfall, fountain, spiral build and fix, rapid prototyping, incremental,
and synchronize and stabilize. The oldest of these, and the best known, is the waterfall model: a
sequence of stages in which the output of each stage becomes the input for the next. These stages
can be characterized and divided up in

As with any system design and implementation, it's imperative to follow the tried and true
methodology of the system development life cycle (SDLC). Adherence to the SDLC sets the stage
for successful systems from design to death. In addition, key points during the life cycle of the
system are addressed and not overlooked. Of utmost importance with an electronic health record
(EHR) system, amongst many other systems, is security. During the initiation phase of an EHR, it's
imperative to keep security at the forefront of discussions. There is actually quite a bit of resources
that need dedicated to the needs of security at this point. The facility information security officer and
key stakeholders should be engaged early on in the discussion of an EHR system. This will ensure
appropriate focus on not only institutional security policies related to healthcare data, but also at
state and federal regulations aimed at safeguarding healthcare data and the systems that contain it. In
addition, at this phase it's imperative to discuss the what the business impact to the organization
would be should the system be compromised and/or suffer catastrophic failure, so that recovery
plans and options can begin to be visualized. This is the common goal of a business impact analysis
and disaster recovery review. Another key point of focus during the initiation phase would be to
look towards the development of the system with regards to infrastructure needs to maintain privacy

Rather, a Gantt chart treats each activity as if it were independent of the others, which of course is
not really the case. For this reason, Gantt charts are better suited for systems implementation
projects that are not complex and have relatively few interrelationships among implementation
activities." (p.436)
It helps to look at the software as a framework that can be modified in hundreds of different ways to
support your organization's culture. If you have a disciplined organization with projects that are well
defined and stable, you can implement many system capabilities relatively quickly to streamline and
simplify formerly manual processes. However, if your organization is new to the field of project
management, you might have to introduce system features in several phases so that the learning
curve is not too steep. Another factor, which could be considered in planning the scope and phasing
of your implementation are the history and type of project. (informit.com) There are so many
different types of project management software that runs on desktop or notebook computers can
perform these tasks easily and quickly, can enable a project leader to plan and control
implementation tasks, and can help a team install a new system on time and within budget.
Examples of project management software solutions include SAP, Agile, Microsoft Project,

Systems Life Cycle : Development And Success Of A Project...
Systems Life Cycle The continual strive for world class health care has identified the systems life
cycle as an import element to improve patient care. Systems development life cycle is a "phased
approach to analysis and design which holds that systems are best developed through the use of a
specific cycle of analyst and user activities" (Kendall & Kendall, 2014, p.4). The seven phases of the
systems life cycle are identifying problems, determining human information requirements, analyzing
system needs, design the system, developing and documenting software, testing and maintain the
system, and implementing and evaluating the system (Kendal &Kendall, 2014). The roles of the
nurse informatician and a project manager play an integral part in the development and success of a
project.
Nurse Informatics Professional in Project Management A nurse informatics professional and a
project manager share several roles and responsibilities. "Project managers and informaticians
interface to ensure that project timelines and budget projections are on target" (McLane &Turley,
2011). Both professions have a goal of successful implementation of an organization's ambition and
vision. A nurse informatics professional applies their expertise and skills as medical professional
with the knowledge of data management. This bridges the gap between nursing and informaticians.
Unlike the tailored knowledge of a nurse informatician, project managers specialize in execution of
project. They may not

Traditional Systems Development Life Cycle Essay
Introduction Today, many project managers and organizational leaders grapple with the question, is
the traditional Systems Development Life Cycle (SDLC) and the supporting Project Management
Life Cycle (PMLC) processes relevant for todays projects? Depending on the level of completeness
of the specifics known at the time the Requirements Breakdown Structure (RBS) is developed, a
choice is needed to be made as to the appropriate approach to plan and manage the project. Hence,
an agile approach could be the right solution. This writing assignment takes a close look at the
considerations confronted by the Pizza Delivered Quickly (PDQ) business to help with the decisions
needed to fulfill the PDQ application requirements and manage the project. Generate the RBS for
the Inventory Management sub–system project and choose the model you will use. Rank order the
specific models from best fit too worse fit, and state your rationale for that ranking? Before most
projects are developed, requirements must be identified and defined. In the case of the PDQ project
we will refer to this process as defining the Requirements Breakdown Structure (RBS). The RBS
informs the developer as to what is to be completed and is usually packaged in the format of
deliverables. These well–formatted deliverables are further broken down into workable deliverables
known as Work Breakdown Structure (WBS) deliverables. There is a slight difference in a RBS and
a WBS. The RBS is less complete than the

System Development Life Cycle Essay
Computer system plays an important role in solving human problem in their daily life. There are
standard steps in order to develop information system called System Development Life Cycle
(SDLC). SDLC is the framework available to build a complete system. There are five phases in
SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in
Appendix 1). The first phase in SDLC is planning. In this phase, the potential system development
project is identified. Project manager summarizes all strength and weakness that possible to occur
using their professional skills (Hoffer, George, & Valacich, 2008). Next, business plan is defined and
documented by project manager in a formal format. According to Burch ... Show more content on

The interview session has been done by include an open–ended and closed–ended question which
are related to the implemented project. Next, sampling technique is executed by system analyst who
does evaluation to the current system or prototype. These processes give feedback in evaluation
form that filled after tested the system. Lastly, observation is performed by using questionnaire
form. According to Burch (1992), the questionnaire is analyzed and transform into structured form
that easy to understand. After all information has been collected, structuring of system requirement
takes place. It focused on development process modeling which perform "graphically representing
the process, or actions, that capture, manipulate, store, and distribute data between a system and
environment" (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is
structured by system analyst using special tools and techniques to create a decision table. According
to Hoffer, George and Valacich (2012), decision table is a "diagram of process logic where the logic
is reasonably complicated" (p. 200). This table is useful to help system analyst to make a decision
toward the project. Then all information's gained from this phase are documented in System
Analysis Report (SAR) that acts as a guideline or reference to the future system development project
(Burch, 1992). The next phase in SDLC is design. According to Weitzel and Kerschberg

System Development Life Cycle

development process, although it is also a distinct process independent of software or other
information technology considerations. It is used by a systems analyst to develop an information
system, including requirements, validation, training, and user ownership through investigation,
analysis, design, implementation, and maintenance. SDLC is also known as information systems
development or application development. An SDLC should result in a high quality system that

For example, a piece of software may be backward–compatible with an older version of itself.
Development
Development is the translation of the program design into a software product. In this stage workable
solutions are made of our design. There are two main activities
File Creation and Application program creation. The personnel involved again are the developers
and senior programmers. Software development is sometimes understood to encompass the
processes of software engineering. There is detailed documentation at this stage like Data
Dictionary, Operating Instructions and Input and Output Specifications.
Some tools we use to achieve these features: structured programming object–oriented programming
standards compliance documentation Testing
Testing includes the process of executing a program or application with the intent of finding errors
Software testing is a technical investigation done to provide users with information about the quality
of the system under test, with respect to the context of its specifications. Testing allows for a
criticism or comparison between programs. Test will be carried out by the Systems Analyst or the
Senior Programmer. There is also a practice in which software testing is done at the same moment
the project starts and it is a continuous process until the project finishes or else it is done at the end.
At this stage documents generated are Test log, Test plan, Test data and Test results

The Information Technology (IT) Security Certification and Accreditation (C&A) process evaluates
the implementation of an IT system or site against its security requirements. The process produces
evidence used by a designated manager as part of the basis for making an informed decision about
operating that IT system or site. The NSTISSI2 NATIONAL INFORMATION SYSTEMS

"comprehensive evaluation of the technical and non–technical security safeguards of an IS to
support the accreditation process that establishes the extent to which a particular design and
implementation meets a set of specified security requirements" and accreditation is a "formal
declaration by a Designated Approving Authority (DAA) that an IS is approved to operate in a
particular security mode at an acceptable level of risk, based on the implementation of an approved
set of technical, managerial, and procedural safeguards" (SANS Institute, 2007, p. 1).
"The NIACAP establishes a standard national process, set of activities, general tasks, and a

Overview of System Development Life Cycle (SDLC)
System development life cycle is a process use for the period of development system. SDLC
contains four main steps those are analysis, planning, design and implementation during the analysis

SDLC is methodology utilization throughout the improvement of programming framework
beginning from arranging until the execution stage. Information stream outlining, on the other hand,
is utilized to prepare the procedure model throughout the examination stage [12]. Procedure model
is exceptionally imperative in characterizing the prerequisites in a graphical perspective.
Accordingly, the unwavering quality of the methodology model is the key component to enhance the
execution of the accompanying stages in
SDLC.
SDLC is likewise used to see on how an data framework can help business necessities, outlining the
framework, fabricating the framework and conveying the framework to clients [12]. SDLC
comprises of four principal stages, which are examination, outline, execute and testing stages.
In the examination stage, prerequisites of a framework are distinguished and refined into a
procedure model. Procedure model could be utilized to speak to the methodologies or exercises that

Agile methods are based on giving high priority to the customer involvement early in the
development cycle. It incorporates testing by the customer early in the process and often as possible.
Testing is usually done at each point when a stable version becomes available. The foundation of
Agile approach is based on starting testing at the beginning of the project and which continues
through the end of the project. Comparison of Waterfall methodology and Agile Methods of
Development Waterfall and agile methods of development are not the only two methodologies
available, but they generally are among the common methods used to deliver projects. Each has its
individual merits, but sometimes one method is more appropriate for a particular project than the
other. The waterfall and the agile are both usable methodologies and each have its own strengths and
weaknesses. Waterfall is attempting to predict the future and whereas Agile is all about responding
quickly to the present. The most critical parts of agile are designed first. Agile provides for adding
new parts to existing ones. Customer can change the requirements anytime, that is why the parts are
designed as separate elements, and the structure of one element does not influence much on the
others. Whereas, in waterfall methods, project is planned from top to bottom at once. Developers
have to take into account every detail of the

5. Deployment and maintenance: Once the software is approved, it is implemented and kept
functioning through maintenance. As the reader may notice, I am using both terms software and
system. The SDLC can be applied to either one. However, to be clear, there are differences. A
system is a collection of components and processes. A system can be made up of one or more types
of software. Interestingly, according to Shah, the "innovation and thought leadership" derived from
software development has encouraged those that develop the overall systems to implement the
software development models and concepts. For the sake of this paper, the "S" in SDLC will be
referred to as software. Most importantly, as Shah implied, it is imperative for the SDLC to be
implemented to help define requirements, reduce overall development and maintenance costs, and to
produce a feasible product. Does one size fit all? Ruparelia contends that different methods of the
SDLC should be implemented depending on the type of software being developed. A Comparison of
Software/System Development Methods 3 The Waterfall Method Over time there have been
numerous methods developed to implement the SDLC. The more traditional, and arguably oldest,
method is the waterfall method. Just as the name suggests, this method is a sequential process where
each phase or stage flows into the next. Ruparelia identifies that waterfall was first documented by
H.D. Benington in 1956, but

Abstract Enterprise resource planning (ERP) systems are recognized for their distinguished features
and integrative information systems in organizations, such as data circulation in financial accounting
systems and human resource information systems. However, they are also known to be complex
systems with multiple operating systems and applications that require several strategies to follow;
for organizations to achieve their corporate growth objectives. Hence, a good approach to solving
the problem of complexity is in adopting a high–level architecture model which can be used to
describe the components of the system and their relationship. In this paper, an effective approach to
systems development is discussed alongside several ERP architecture methods. Several ERP
implementation strategies are highlighted and requirements are shared. Key Words ERP systems,
ERP architecture, implementation strategies, system development life cycle Background According
to Motiwalla & Thompson (2012), "the system development life cycle (SDLC) provides useful
guidelines to the ERP implementation process" (p. 90). It is a process of developing new

The Development Of The System Development Life Cycle
Data processing was an art rather then a science. The length of a project was hard to predict, along
with the cost and degree to which how the problem was first initiated. The new leadership of Tony's
Chips has decided to move the website to an internally hosted site instead of its current external site.
The newer internal website should be redesigned in order to allow customers to buy products online.
The development of the System Development Life Cycle (SDLC) created a much easier way to
develop systems. This process will be used for Tony's Chip's new independent company. Each step
in this process is clearly defined through each individual phase. The SDLC consists of five different
phases that will be utilized in this project. The five phases are systems planning, systems analysis,
systems design, systems implantation, and systems support and security. The sequential steps are
often called "a waterfall" because each phase should be completed before moving on to the next.
Once a phase is completed, there is no returning to it. Overview of the Required Web Architecture
Building the web architecture is possibly the most important step in the systems planning phase. You
will be able to establish the foundation of the project, followed by the beginning decisions that will
reflect the entire system during the systems planning phase. By understanding and familiarizing

The security systems development life cycle (SecSDLC) uses the same phases as the systems
development life cycle. Although the two processes are different due to what each is used for and
the activities associated with them, Michael Whitman and Herbert Mattord claim "the overall
methodology is the same." (2012, pg. 26). Since a business, company, or an organization with a
network must consider the many technologies and methodologies available today, for an effective
security control plan, one would be remiss not to follow the SecSDLC phases:
1. The Investigation phase is engaged with "a directive from upper management, dictating the
process, outcomes, and goals of the project, as well as its budget and other constraints" (Whitman &
Mattord, 2012, pg. 26). During this phase, all interested parties discuss whether the organization has
the funds and commitment to move forward with a potential plan.
2. The Analysis phase is engaged when documentation from the investigation phase is reviewed.
The team will analyze current policies and threats, and "relevant legal issues that could affect the
design of the security solution" (Whitman & Mattord, 2012, pg. 27) as well.
3. The Logical Design phase is engaged when the analysis of the plan is complete. This phase is
where the team "creates and develops the blueprints for information security" (Whitman & Mattord,

Information technology governance refers to aligning the strategy of the IT department with the
strategy of the organization. IT governance is carried out by aiming at ensuring that companies
maintain their level of operation striving to achieve their goals and strategies while at the same time
finding better ways of measuring the performance of information technology within the
organizations. Information governance guarantees that interests of the stakeholders are well taken
care of as well as ensuring that realistic results are achieved from the organizational activities

The third step is the design stage which involves the requirements for the design of the technology,
and these include data layers, programming language, and the data services. This stage helps in
implementing a design that highlights the coverage of the business logic that was analyzed at the
previous stage. The next step is the coding which involves writing the sources of the actual code that
will be used in the implementation of the business logic, the models, and the integrations of the
services that had been generated earlier. The fifth stage is a testing step where testers such as beta
testers are solving issues that arise out of the application (Petersen & Baca, 2009). However, this
stage usually tends to repeat the coding stage so that there can be proper squashing of the detected
bugs. The final stage is the operation stage where the application is considered complete and can be
deployed. Besides, this stage involves maintenance and support in ensuring the application remains
updated and fully operational (Petersen & Baca, 2009).
The Purpose of the Model
The waterfall model should be used in certain situations. For instance, waterfall models should only
be applied when the requirements are clearly known and properly fixed (Tutorials Point, n.d.). They
can also be used when there is a stable definition of the product, a distinct understanding of the
technology, or when ambiguous requirements are

Systems Operation, Support and Security

Introduction ARC is an established brand that operates in the car racing industry. They are based in
Australia with a customer base, both locally and internationally. The organisation is planning to
expand to Hong Kong and Shanghai during the coming year. They developed a system to assist
them with their customers, which was growing tremendously. ARC integrated with Wincarz, which
is a smaller yet successful organisation in the racing car industry. WinCarz used an off–the–shelf–
CRM system to manage the customer relations. The integration allowed them the freedom to
combine operations, personnel relations and systems together, and operate under the ARC banner.
The integration of the CRM systems of ARC and WinCarz created conflicts. The following report
discusses the appropriateness of the integration in a technical and business perspective. 1.
Immediate Integration Recommendation SDLC methodologies are the steps that a developer works
by to have a highly structured procedure running during the development of any software. (Massey
and Satao,2012) The stages of the system development life cycle requires research, observation,
dedication and user focused development. ARC and Wincarz may have had different protocols they
worked by, and this makes their company systems least a little bit different to the other. Simply, the
research or the dedication put for the development/customization of the initial systems would be
unrelated, making developing a system with the best of both

Plan This iteration will cover the development phase of the systems development life cycle. This
iteration has two objectives: (1) To learn what processes take place in the development phase at
Almac (2) Learn how the process at Almac differs from other companies in the industry. My plan is
to interview a systems developer from Almac and a systems developer from another company. I
have selected Anne Beeman from Almac Group and Nestor Ramirez from Century 21 the
department store. Anne has worked as a systems developer for Almac Group for three and a half
years. I selected her because she has worked in both developing new studies and also in maintaining
existing studies. Anne will provide more insight ... Show more content on Helpwriting.net ...
I will present him with the options of a Face time video call or a standard telephone call. I believe
that the interviews will happen within a matter of days. I will ask Anne if she is available on
Wednesday March 2, 2016. I am hoping that Nestor will be available on the same date as Anne just
later in the day. These meetings are very important because developers bring all the aspects of the
planning and analysis phases to life. These interviews will give me in depth knowledge about what
processes developers take to code a project. I am also interested to know what their involvement is
throughout the varying stages of the systems development life cycle.
Action
I asked Anne if she'd be willing to participate in my project in person. She agreed and said that I
could schedule a meeting whenever I was open. My interview with Anne happened on the 2nd of
March. I arrived at the meeting room a bit earlier than our scheduled time so that I could setup and
prepare. She was about 20 minutes late because her lunch went late but I had scheduled ample time
for us to chat so I wasn't worried. The questions I prepared for Anne are shown in Figure 1 below:

followed. However, conversation with Anne flowed easily and so I also had the opportunity to ask
supplemental and supporting questions in response to her

System Development Life Cycle ( Sdlc ) Methodologies
Businesses rely heavily on their information systems for decision making, an essential component of
organization management. Information systems serves several purposes in a business, ranging from
transactions and assisting leadership with difficult strategy formulation. Advances in computer–
based information technology in recent years have led to a widely variety of systems that managers
are now using to make and implement decisions (Alter, 1976). In today's businesses, systems
development is a process of examining a business situation to analyze better procedures and
methods to stay competitive. System development life cycle (SDLC) methodologies are promoted as
means of improving the management and control of the software development process, structuring
and simplifying the process by specifying activities to be done and techniques to be used (Russo,
1995). Every businesses have different types of projects that have different requirements. Therefore,
businesses must choose the SDLC phases according to the specific needs of the project. There are
different types of SDLC. These are Waterfall Model, V–Shaped Model, Prototyping Model, Spiral
Model, Iterative Incremental Model, and Extreme programming (Agile development) (Sami, 2012).
Each of the models has different level of risks and benefits to cope with the project requirements.
This paper will discuss the processes of System Development Life Cycle methodologies that makes
it excessively formal and rigid and

A Comparison of the System Development Life Cycle and the Risk Management Framework The
System Development Life Cycle (SDLC) and the Risk Management Framework (RMF) are both
processes that are critical to the overall function of an information system, however many project
managers and system developers working with the SDLC regularly neglect to incorporate the RMF
steps into the development of information systems. This lack of planning and foresight often has
unexpected financial impacts, or worse, adverse security effects to an organization later on. Is it
possible these individuals overlook the RMF because it is difficult to follow or does not align well
with the SDLC? What is the purpose of, and the steps involved with each of these ... Show more

During SDLC phase one, the initiation phase, "the need for a system is expressed and the purpose of
the system is documented" (NIST, 2008). Some of the expected outcomes from this phase would be
a project plan and schedule; system performance specifications outlining the operational
requirements, system design documents, and a document that defines roles and responsibilities. The
corresponding RMF step, security categorization, establishes the foundation for security
standardization among information systems and provides a vital step towards integrating security
into the information system (NIST, 2008). During this step, the type(s) of information processed by
the information system are identified and the information system is categorized to determine the
level of protection requirements to put in place. Some of the expected outputs of this step include a
security project plan and schedule, documented system boundary, the system categorization, and the
security roles and responsibilities. These two process steps are very similar except the focus of RMF
is on information security related functions. In some cases, SDLC produces the expected outputs
that RMF requires, and the security professionals only require a copy of the documentation for their
records. For example, the system design document often depicts the system boundary. The reason
this step is so critical is that it

System Development Life Cycle Models The concept of making employees to form a work group is
very simple. But to make it fit the system is challenging. System Development Life Cycle uses
certain principles to assure that systems meet their requirements (DOJ, 2000). These principles
impose various degrees of discipline to the process to make it efficient and even predictable. The
entire model goes through certain phases of investigation to System Operation. It is matter of
personnel choice entirely to develop any model. Each model will suit only particular conditions. The
main challenge is to select the correct model for the system to make more efficient. THE SEVEN

"The systems development life cycle (SDLC) is the process of determining how an information
system (IS) can support business needs, designing the system, building it, and delivering it to users"
[1]. There are several approaches (models) to the SDLC but purpose of the each approach is the
same. Each and every process comprises of phases: Planning phase, Analysis phase, Design phase,
Implementation phase, and Maintenance phase. The Planning phase is phase related to the planning
of the system such as initial system request, feasibility analysis and project plan; Analysis phase is
the phase which is related to the analysis of the system, in this phase analysis such as requirement

It also identifies the important risks associated with the project that must be managed if the project
is approved [1].
Example:
Now to go into further details of the feasibility, we have to define the types of feasibility. There are
three types of feasibility
Technical Feasibility– It is the type of feasibility which deals with the technical specifications of the
system and verifies the project feasibility within the limits of current technology? Does the
technology exist at all? How complex is the system? These are the various aspects which are dealt in
the technical feasibility of the system [1].
Economic Feasibility– It is the type of feasibility which deals with money related issues in the
company. This is also known as cost–benefit analysis. This attempts to answer the question "Should
we build the system?" Economic feasibility is determined by identifying costs and benefits
associated with the system, assigning values to them, calculating future cash flows, and measuring
the financial worthiness of the project. As a result of this analysis, the financial opportunities and
risks of the project can be understood. These are the aspect which are dealt in economic feasibility
[1].
Organizational Feasibility– It is the type of feasibility which deals with "how well the system
ultimately will be accepted by its users" [1], how is the overall market for the system, is there any
legal concern about the system? [1]. The various organizational factors that can

Makedonia Palace, after a request from the company that has the hotel, Black and White A.G, so
through this system can make it easier to track the management area where the company needs.
Throughout the course of building the system will be followed some basic steps that should be done
which and is called Systems Development Life Cycle (SDLC). Of course all this will be discussed
below, as are the potential risk that may exist in order to fail the system, if not all, of any party, and
to suggest some alternative proposals. Company profile First of all, before analyze all the above,
let's analyze a little the profile of the hotel something which is very important so that can proposed a
system as close as possible to the standard of the hotel. The Makedonia Palace is based in the second
largest city in Greece, Thessaloniki since 1980 and is one of the most historic hotels in the country.
The hotel offers countless services to its customers such as covered parking, jewelry store, sports
facilities and catering but also a friendly and very good environment to employees that helps them to
improve themselves constantly. In 2013 the hotel has undertaken by a new entrepreneur who put the
aim to improve the facilities and the services of the hotel to the client but also for the employees.

Planning
In the planning phase, a Project Charter is provided to all management, stakeholders and those with
significant authority over the company. The Project Charter essentially defines the project. It
contains the objectives of the project describing the deliverables, while also containing a description
of the criteria used to assess when each section is completed, risk assessments and identifies
stakeholders and management (Documentation Consultants, n.d.). The Project Management Plan is
also produced during the planning phase. It contains the project's schedule and milestones, required
resources and cost estimations and budgets.
To start off the planning you must study the current system with the people involved (such as
clients, employees or management). These groups would have meetings to discuss areas of the
system that could be improved and suggest possible solutions. In these meetings, agendas are given
out so that everyone knows what the objectives are. Notes are recorded to be reviewed during
requirements analysis.
Also included in the analysis phase is a feasibility study. As the name would suggest it simply
assesses if the new system is feasible within the budget and manpower of the company. (Overton,
2007)
It would determine if the project should even be started and if would it be possible to make it within
the budget –

System Development Life Cycle (SDLC)
The Systems development life cycle (SDLC) is a conceptual model that is used in the project
management which describes the stages involved in the information system development project,
from an initial feasibility study through maintenance of the completed application. SDLC is used to
correct problems in existing system, and to improve the system quality and structure. It certainly
makes the process easy for building a system and helps to reduce failures such as unclear objectives,
possibility of not meeting the user needs, or cost overruns. We can generally consider the SDLC in
five phases. These 5 phases are repeated until the desired or efficient output is achieved. The 5
phases of system development life cycle are:
1. Planning
2. Analysis
3. Design
4. Implementation
5. Maintenance
1. Planning:
This phase begins when the project is defined and the appropriate resources have been selected. The
first part of the planning phase involves collecting, defining and validating functional, support and
training requirements. The second part involves developing initial life cycle management plans,
including project planning, project management, Configuration Management, support,

Intro to System Analysis and Design
Introduction to System Analysis and Design 1. INTRODUCTION Systems are created to solve
problems. One can think of the systems approach as an organized way of dealing with a problem. In
this dynamic world, the subject System Analysis and Design, mainly deals with the software
development activities. 2. Defining Your System A collection of components that work together to
realize some objective forms a system. Basically there are three major components in every system,
namely input, processing and output. [pic] In your system define the different components that are
connected to each other and how they are interdependent. Remember the objective of the system
demands that some output is produced as a result of processing the suitable ... Show more content on

System Analysis also includes sub–dividing of complex process involving the entire system,
identification of data store and manual processes. The main points you are to discuss in your papers
regarding system analysis are: Specification of what the new system is to accomplish based on the
user requirements. Functional hierarchy showing the functions to be performed by the new system
and their relationship with each other. Function network which are similar to function hierarchy but
they highlight those functions which are common to more than one procedure. List of attributes of
the entities – these are the data items which need to be held about each entity (record) (d) System
Design Based on the user requirements and the detailed analysis of a new system, the new system
must be designed. This is the phase of system designing. It is a most crucial phase in the
development of a system. Normally, the design proceeds in two stages: preliminary or general
design Structure or detailed design Preliminary or general design: In the preliminary or general
design, the features of the new system are specified. The costs of implementing these features and
the benefits to be derived are estimated. If the project is still

The System Development Life Cycle Framework
Prior to Zachman, organizations often introduced information systems technology in direct response
to a perceived need by the organization such as the automation of a particular job function (Bernard,
2011). As Bernard notes, this became increasingly problematic as organizations evolved as did their
need for integration and communication between their system implementations. Systems developed
to meet business requirements on a case by case basis often using proprietary vendor products which
eventually led to heterogeneous collection of disharmonious systems (Bernard, 2011). Zachman
Framework Compared to the System Development Life Cycle Framework The most common
approach to developing a system during the time Zachman created his framework was the System
Development Life Cycle Framework (SDLC) (Collins, 2008, February). SDLC is typically divided
into five phases which are planning, analysis, detailed system design, implementation, and
maintenance (Coronel & Morris, 2015). Each of these phases is intended as a gate which must be
passed through before proceeding to the next (Coronel & Morris, 2015). With this structure in mind,
it should be clear that while it may be possible to revisit the planning phase during the analysis
phase, the converse would certainly not be possible. Consequently, this emphasizes perhaps the key
and fundamental difference between the two approaches. Even a cursory glimpse at the initial
Zachman (1987) framework would not reveal a series of
