Rapid Application Development

Rapid Application Development

1. MAIN FEATURES

   • ITERATIVE
     • REPEATS OVER AND OVER
   • CREATES PROTOTYPES

2. SOFTWARE DEVELOPMENT

3. SIMPLIFIES THE WORK LOAD

   • BROKEN DOWN INTO STAGES

4. Prototype types

   • Pilot Prototype
     • Used to determine a design approach.
     • it guides the planning decisions of how the project is to be carried out
   • Modelling prototype
     • these are created to test to see if the prototype fits the requirements of the customer
     • Throwaway
       • prototype is thrown away after being discussed or evaluated
     • Evolutionary
       • code is retained and used to develop more detailed prototype

5. Pros

   • customer doesn't have to be 100% sure what they want
     • Improves quality ( compared to waterfall)
       • focuses on speed of development, so customer can see it early
         • risk analysis is a key feature, pilot prototypes can help assess risk early on
           • Good for small to medium projects with high collaboration

6. Cons

   • requires significant time commitment
     • risk of poorly designed product
       • requirements may be less well defined
         • not easy to use for large projects
