Iterative Development

Waterfall model iterative -> spiral model

Chararter

  1. Small steps, feedback and refinement and adaption

  2. Iterative & incremental

  3. Time-boxed ( Prepare fixed deadline )

-> iterative development : each function is done step by step

-> hard or unknown function is early done then easy function

Benefits

  1. Early mitigation of high risks

  2. Early visible progress

  3. Early feedback, user

  4. Managed complexity

  5. Can improve the process itself, iteration by iteration

Procedure

  1. inception
  2. ealboration
  3. construction
  4. transaction
    -> each step has done all job but more important job than other
