(20 marks) Task 3

  1. What is a feasibility study? Why is it important? (5 marks)

A feasibility test can be define as a controlled process for indentifying problem and opportunity, determining objective, describing situations, defining successful outcomes and assessing the range of cost and benefit associated with several alternative for solving problem. It is an operation plan that review criteria to determine whether or not a plan is within the capacity of the resources that can be made available test.

Feasibility test is important in sense that it used to determine if the project should get the go-ahead. If the project is to proceed, the feasibility study will produce a project plan and budget estimates for the future stages of development. Besides that, it also establishes a high-level view of the intended project and to determine the budget. The business feasibility study is an effective way to safeguard against waste of investment or resource. The research and information uncovered in the feasibility study will support the business planning stage and reduce the research time. Hence the cost of business plan will also be reduced.

  1. What are the five aspects of feasibility? (5 marks)

  1. Technology and system feasibility

(ii) Economic feasibility

(iii) Legal feasibility

(iv) Operational feasibility

(v) Schedule feasibility

c) Explain briefly the five phases of the systems development life cycle. (10 marks)

6. Once the new system is up and running for a while, it should be exhaustively evaluated. Maintenance must be kept up rigorously at all times.
5. The system is put into use. This can be done in various ways. The new system can phased in, according to application or location, and the old system gradually replaced. In some cases, it may be more cost-effective to shut down the old system and implement the new system all at once.
4. The new system is developed. The new components and programs must be obtained and installed. Users of the system must be trained in its use, and all aspects of performance must be tested. If necessary, adjustments must be made at this stage.
3. The proposed system is designed. Plans are laid out concerning the physical construction, hardware, operating systems, programming, communications, and security issues.
2. The new system requirements are defined. In particular, the deficiencies in the existing system must be addressed with specific proposals for improvement.
1. The existing system is evaluated. Deficiencies are identified. This can be done by interviewing users of the system and consulting with support personnel.

(10 marks) Task 4

  1. Describe the features of (PERT) Charts Project Evaluation and Review Technique. (5 marks)

Feature of a PERT

  1. It identifies the specific activities and milestones.

  2. It determines the proper sequence of the activities.

  3. Construct a network diagram.

  4. Estimate the time required for each activity.

  5. Determine the critical path.

  6. Update the PERT chart as the project progresses.

  1. What is a Gantt chart and explain the main features of the Gantt chart. (5 marks)

A Gantt chart is a project management tool that represents the timing of projects or tasks as they occur within a given timeline. Since Gantt charts are easy to understand, they are used by most project managers and collaborators to illustrate progress.

(20 marks) Task 5

  1. As the system analyst designing and implementing a new Accounting Information System list the reasons why you conduct the acceptance testing. (8 marks)

Acceptance testing is conducted to:

    1. Establish compatibility between the new system and old system. This will facilitated a smooth transition during implementation.

    2. Enable the vendors to establish the risk that a new system can bring once it is implemented.

    3. Familiarize the technical formulas that vendor can use and relate to some magical mix of transaction and process of the company before designing and new system.

    4. Adequately match the expectation of the new system on the personnel that are to utilize the new system.
