Rapid Application Development

MAIN FEATURES
1. ITERATIVE
  1. REPEATS OVER AND OVER
2. CREATES PROTOTYPES
SOFTWARE DEVELOPMENT
SIMPLIFIES THE WORK LOAD
1. BROKEN DOWN INTO STAGES
Prototype types
1. Pilot Prototype
  1. Used to determine a design approach.
  2. it guides the planning decisions of how the project is to be carried out
2. Modelling prototype
  1. these are created to test to see if the prototype fits the requirements of the customer
  2. Throwaway
    1. prototype is thrown away after being discussed or evaluated
  3. Evolutionary
    1. code is retained and used to develop more detailed prototype
Pros
1. customer doesn't have to be 100% sure what they want
  1. Improves quality ( compared to waterfall)
    1. focuses on speed of development, so customer can see it early
      1. risk analysis is a key feature, pilot prototypes can help assess risk early on
        Good for small to medium projects with high collaboration
Cons
1. requires significant time commitment
  1. risk of poorly designed product
    1. requirements may be less well defined
