Jackson System Development - JSD Steps

JSD Steps

When it was originally presented by Jackson in 1982, the method consisted of six steps

  1. Entity/Action Step
  2. Initial Model Step
  3. Interactive Function Step
  4. Information Function Step
  5. System Timing Step
  6. System Implementation Step

Later, some steps were combined to create a method with only three steps.

  1. Modelling Stage (Analysis): with the Entity/Action Step and Entity Structures Step.
  2. Network Stage (Design) : with the Initial Model Step, Function Step, and System Timing Step.
  3. Implementation Stage (Realisation) : The implementation Step.

Famous quotes containing the word steps:

    “The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Child’s play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
    —Erik H. Erikson (20th century)
