Analysis- separation of a substance into parts for study and interpretation; detailed examination. substance- business system Parts – various subsystem we are deﬁning systems analysis as that part of the process of systems development that begins with the feasibility study and ends with the production of target document.
A systems analyst will be required to perform a number of different tasks in carrying out the analysis phase of a development project. 5 areas have been identiﬁed into which these tasks can be grouped.
Planning the approach Asking questions and collecting data Recording the information Interpreting the information collected Specifying the requirement
“failure to prepare is to prepare to fail”. What type of information is required? What are the constraints on the investigation? What are the potential problems that may make the task more difficult?
As part of the planning process, analysts must ensure that: They understand the objectives and terms of reference agreed with the client; They are aware of constraints that affect the analysis process; They plan the research, initial contact and other tasks to be completed during the investigation and manage time appropriately.
Who initiated the project? What is their role in the organisation? What are their objectives for the project? What are the company objectives?
The stated objectives of the client will usually be recorded in the terms of reference. Defines SCOPE Of system. System boundary. Constraints. Objectives. Permission. End product.
Ifno written terms of reference exist, the analysis team would be well advised to prepare a draft based on their understanding and present it to the client for agreement.
Gather information face-to-face contact with the client. Focus on conﬁdentiality, integrity, respect and conﬁdence-building. Recognise expertise in the users and welcome their input. Have as a key objective the need to build the client‟s conﬁdence. Keep everybody informed. This includes client contacts and project staff. Be discreet and diplomatic. Double-check any information gathered.
Effective use of time. List objectives and set priorities. Make a daily „to do‟ list. Handle paper only once. Set and keep deadlines. Always carry a notebook . Do it now .
Small- scale system analysis. Analysts should concentrate on providing the answers to four key questions: How much? The cost of the new system. What? The objectives of the new system. When? The delivery timescale. How? The means and procedures used to produce the new system.
The feasibility study report has to address three levels of feasibility: Technical feasibility. Business feasibility. Functional feasibility
