Fit 2001 week 2:
The Context Systems Analysis and Design
1. Phases of system development of life cycle (SDLC):
a) Planning (important to confirm the feasibility of the project)
b) Analysis (important to understand the business needs)
c) Design
d) Implementation
e) Support (maintain, enhance, support)
2. Scheduling project phases:
a) Waterfall approach- each phase falls into next phase
b) Overlapping (current) approach
c) Spiral model: and adaptive SDLC approach that cycles over and over again through development activities until a project is complete.
3. Methodologies and models:
a) Methodologies: comprehensive guidelines to follow for completing every SDLC activity collection of models, tools and techniques.
b) Models: representation of an important aspect of real world, but not some real thing
c) Tools: software support that helps creating models and other required project components.
d) Techniques: collection of guidelines that helps analyze complete system development activity or task.
4. Two approach
a) Traditional approach
b) Object-oriented approach-views information system as collection of interacting objects that work together to accomplish objects.
5. Confirm project feasibility:
a) Economic feasibility:
i. CBA-cost/benefit analysis
ii. Intangible cost/benefit cannot be measured in dollars
b) Organizational and cultural feasibility
c) Technological feasibility
d) Schedule feasibility
e) Resource feasibility
f) Staffing and launching feasibility.
