 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.
B  model
 Waterfall
 V model
 Spiral model
 Traditional
            approach
        Analysis requirement
        Specify requirement
        Produce high level design
 Modeling
 Partitioning
 iteration
 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
 Background
     Terms of reference.
      Reasons for the study.
 The current situation
       Overview of current situation.
       Problems and requirements identified.
 Proposed solution
      Technical implications.
      Operational implications.
      Cost implications.
 Cost– benefit analysis
 Recommendations
