1c - Development Methodologies

1. Specific ways of completing design and implementation (development)

2. Prototyping

   • Iterative process between design and development
   • System designed as it is developed in stages
     • User evaluates each stage
       • Changes made based on user feedback e.g changes to requirement specification
     • O- User gets to see the actual system instead of just designs
       • O- More effective feedback

3. Rapid Application Development (RAD)

   • Used a lot for mobile apps
   • Prototyping
   • Timeboxing
     • Requirements are set can compared at the beginning and end of each stage
     • O- Requirements can be refined
     • User and developer decide on features for next stage
   • Uses Computer Aided Software Engineering (CASE)
     • Feasibility
     • Gather Requirements
