- 1. Building and Deploying an Information Systems A Key for Successful Organization
- 2. Building and Deploying an Information Systems An Information System (IS) can have a major impact on corporate strategy and organizational success. The involvement of managers and decision makers in all aspects of information systems is a major factor for organizational success, including higher profits and lower costs. Some of the benefits business organization seek to achieve through information systems include: better safety, competitive advantage, fewer errors, greater accuracy, higher quality products, improved communications, increased efficiency and productivity, more efficient administration, superior financial and managerial decision making.

- 4. Information System Architecture Information System Architecture (ISA) refers to the business processes and policies, system structure, technical structure and product technologies required for a business or an information system. The architecture comprises a detailed description of design, contents, list of current hardware, software and networking capabilities of the computerized system. This architecture include both the hardware and software used to provide solution to the customer. It also include details of long-term plans like upgrading and/or replacing old equipment and software.
- 6. Software Development Lifecycle Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality software's. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. SDLC is the acronym of Software Development Life Cycle. It is also called as Software Development Process. SDLC is a framework defining tasks performed at each step in the software development process. ISO/IEC 12207 is an international standard for software life-cycle processes.
- 8. Software Development Models The software development models are the various processes or methodologies that are being selected for the development of the project depending on the project’s aims and goals. There are many development life cycle models that have been developed in order to achieve different required objectives. The models specify the various stages of the process and the order in which they are carried out. The selection of model has very high impact on the testing that is carried out. It will define the what, where and when of our planned testing, influence regression testing and largely determines which test techniques to use.
- 10. Software Testing Software testing is the act of examining the artifacts and the behavior of the software under test by validation and verification. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. It includes Analyzing the product requirements for completeness and correctness in various contexts like industry perspective, business perspective, feasibility and viability of implementation, usability, performance, security, infrastructure considerations, etc.
- 12. Deploying an Information System As an IT service, deployment refers to the methods involved in bringing new hardware or software in order to work properly in its environment; installation, configuration, testing, and any other necessary steps. The deployment requirement specifies the configuration of a software system with its precise requirements. A model that describes the nonfunctional properties of a system in relation to its architecture lays the basis for future design trade-offs regarding nonfunctional properties of system architecture.
