development of the project charter.
 A short document that is prepared for both internal
and external stakeholders
 Provides a high-level overview of the project
 Useful communication tool that helps to assure that
the organizations and other stakeholders understand
the initiation of a project

9
Chapter 5
 A project charter typically contains:

 Project manager name and contact information
 Customer name and contact information
 Projected start and completion dates
 Key stakeholders, project role, and responsibilities
 Project objectives and description
 Key assumptions or approach
 Signature section for key stakeholders

10
Chapter 5
 The key activity of project planning is the
process of defining clear, discrete
activities and the work needed to complete
each activity within a single project.
 The objective of the project planning
process is the development of a Baseline
Project Plan (BPP) and the Project Scope
Statement (PSS).

Chapter 5
Assessing Project Feasibility
(Cont.)
 Economic feasibility: a process of
identifying the financial benefits and costs
associated with a development project
Often referred to as a cost-benefit analysis
Project is reviewed after each SDLC phase in
order to decide whether to continue, redirect,
or kill a project

19
Chapter 5
Determining Project Benefits
 Tangible benefits refer to items that can
be measured in dollars and with certainty.
 Examples include:
reduced personnel expenses,
lower transaction costs, or
higher profit margins.

20
Chapter 5
(Cont.)
 Most tangible benefits will fit within the following
categories:
 Cost reduction and avoidance
 Error reduction
 Increased flexibility
 Increased speed of activity
 Improvement of management planning and control
 Opening new markets and increasing sales
opportunities

21
Chapter 5
(Cont.)
 Intangible benefits are benefits derived from
the creation of an information system that cannot
be easily measured in dollars or with certainty.
 May have direct organizational benefits, such as the
improvement of employee morale.
 May have broader societal implications, such as the
reduction of waste creation or resource consumption.

22
Chapter 5
Determining Project Costs
 Tangible cost: a cost associated with an
information system that can be measured
in dollars and with certainty
 IS development tangible costs include:
Hardware costs,
Labor costs, or
Operational costs including employee training
and building renovations.

23
Chapter 5
Determining Project Costs (Cont.)
 Intangible cost: a cost associated with an
information system that cannot be easily
measured in terms of dollars or with
certainty
 Intangible costs can include:
Loss of customer goodwill,
Employee morale, or
Operational inefficiency.

24
Chapter 5
 One-time cost: a cost associated with project
start-up and development or system start-up
 These costs encompass activities such as:
 Systems development,
 New hardware and software purchases,
 User training,
 Site preparation, and
 Data or system conversion.

25
Chapter 5
 Recurring cost: a cost resulting from the
ongoing evolution and use of a system
 Examples of these costs include:
 Application software maintenance,
 Incremental data storage expenses,
 Incremental communications,
 New software and hardware leases, and
 Supplies and other expenses (i.e. paper, forms, data
center personnel).

26
Chapter 5
 Both one-time and recurring costs can
consist of items that are fixed or variable in
nature.
 Fixed costs are billed or incurred at a
regular interval and usually at a fixed rate.
 Variable costs are items that vary in
relation to usage.

27
Chapter 5
 Procurement
 Consulting, equipment, site preparation, capital,
management time
 Start-up
 Operating systems, communications installation,
personnel hiring, organizational disruption
 Project-related
 Application software, software modification,
personnel overhead, training, data analysis,
documentation
 Operating
 System maintenance, rental, asset depreciation,
operation and planning

28
Chapter 5
The Time Value of Money
 Net Present Value (NPV)
Use discount rate to determine present
value of cash outlays and receipts
 Return on Investment (ROI)
Ratio of cash receipts to cash outlays
 Break-Even Analysis (BEA)
Amount of time required for cumulative
cash flow to equal initial and ongoing
investment

29
Chapter 5
The Time Value of Money
 Time value of money (TVM): the concept
that money available today is worth more
than the same amount tomorrow
 Discount rate: the rate of return used to
compute the present value of future cash
flows (the cost of capital)
 Present value: the current value of a
future cash flow

30
Chapter 5
The Time Value of Money (Cont.)
 Net Present Value
PVn = present value of Y dollars n years from
now based on a discount rate of i.
NPV = sum of PVs across years.
Calculates time value of money

31
Chapter 5
The Time Value of Money (Cont.)
 Break-even analysis: a type of cost-
benefit analysis to identify at what point (if
ever) benefits equal costs

32
Chapter 5
Assessing Technical Feasibility
 Technical feasibility: a process of
assessing the development organization’s
ability to construct a proposed system

33
Chapter 5
 The potential consequences of not assessing
and managing risks can include the following:
 Failure to attain expected benefits from the project,
 Inaccurate project cost estimates,
 Inaccurate project duration estimates,
 Failure to achieve adequate system performance
levels, and
 Failure to adequately integrate the new system with
existing hardware, software, or organizational
procedures.

34
Chapter 5
Project Risk Factors
 Project size
 Team size, organizational departments, project duration,
programming effort
 Project structure
 New vs. renovated system, resulting organizational changes,
management commitment, user perceptions
 Development group
 Familiarity with platform, software, development method,
application area, development of similar systems
 User group
 Familiarity with IS development process, application area, use
of similar systems

35
Chapter 5
(Cont.)
 Risk can be managed on a project by:
Changing the project plan to avoid risky
factors.
Assigning project team members to carefully
manage the risky aspects.
Setting up monitoring methods to determine
whether or not potential risk is, in fact,
materializing.

36
Chapter 5
(Cont.)
 The four primary factors associated with the
amount of technical risk on a given project are:
 Project size,
 Project structure,
 The development group’s experience with the
application and technology area, and
 The user group’s experience with systems
development projects and the application area (see
also Kirsch, 2000).

37
Chapter 5
(Cont.)
 Four general rules emerged as technical
risk assessments:
Larger projects are riskier than smaller
projects.
A system in which the requirements are easily
obtained and highly structured will be less
risky than one in which requirements are
messy, ill structured, ill defined, or subject to
the judgment of an individual.

38
Chapter 5
(Cont.)
The development of a system employing
commonly used or standard technology will
be less risky than one employing novel or
nonstandard technology.
A project is less risky when the user group is
familiar with the systems development
process and application area than if
unfamiliar.
