What are primary sections in the planning phase?
Feasibility study (C-B analysis) and Requirements Determination.
What is the primary output of the planning phase?

In addition to using the feasibility study and c-b analysis as tools in the planning phase, which tool (or rather, technique(s)) is used to help determine requirements?
Fact-gathering techniques.
What personnel must be involved?
Users, mgt and analysts.
Criteria for feasibility include:
M (management) AT (appropriate timing) O (organizational goals) P (Practical) W (worthwhile with respect to other projects)
What must an analyst identify about the current and future system in the feasibility study?
What’s wrong with old.
Is new sys. viable &
Should new be made
Outcomes of the feasibility study are:
Estimate of potential benefits of proposed sys. Cost and time estimate. Description of the systems: a.) objectives b.) functions c.) estimated cost
Feasibility Study process is…
- analyze current
- interview
- Fn. Reqmts.
- C-B analysis
- Organizational impact.
What are six important domains of feasibility?
Economic Technical Operational Scheduling Legal/Contractual Political
Operational feasibility refers to what?
If the system is capable of fitting into the business environment.. Esp. in the context of the users interaction with the system.
