L1 - Introduction
Information Systems: An integrated set of components for collecting, storing, and processing data
and for delivering information
Eg. WES: stores
information about students , point of sales: stores transactions and
product information
Systems Development Life Cycle (SDLC)
1. INITIATION: Can it be done?
Key activities:
- Review and prioritise project requests
- Assess project feasibility (Can it be done?)
- Develop Project Plan
Why is it conducted: To determine whether you can get what the client wants on time
and
within budget.
Scope creep: scope is unlikely to stay fixed. Requirements may change, environment may
change. To manage scope creep, through negotiations of timeframes and necessary
requirements. k
2. Analysis
Key Activities
- Determine detailed user requirements
- Create system models to confirm requirements and for design
- Build vs Buy analysis
Why is it conducted: By obtaining a detailed and comprehensive understanding of the
business requirements, the Project Team can develop the Functional Specification that
will drive the system design
