SDLC - Answers - Systems Development Life Cycle
6 phases of SDLC - Answers - 1. Identify
2. Plan
3. Discover
4. Design
5. Build
6.Complete
2 approaches to SDLC - Answers - Predictive and Adaptive
Predictive Approach - Answers - assumes project can be planned in advance and that
the information system can be developed accordingly
-low tech risk
-well understood
-sequential
-ex.waterfall model
Adaptive approach - Answers - Requirements and needs uncertain. Assumes project
must be more flexible and adapt to changing needs as the project progresses
-iterative
-high tech risk
-ex. agile and spiral development
Waterfall Model - Answers - an SDLC approach that assumes the phases can be
completed sequentially with no overlap
Pros of Waterfall model - Answers - -Simple and easy to use
-Well understood and req identified in advance
-Change is minimized
Cons of Waterfall Model - Answers - -early commitment to errors that won't be found
until the end
-no feedback loop
-requires problem is understood fully at the start
-does not account for changes in the biz environment
Agile Development - Answers - Developing work continually and iteratively, with a goal
of more frequent product rollouts and constant improvement across smaller components
of the larger project. Team members nor users completely understand the new system
and are responsive
-2 types: Unified Process and Scrum
