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:

    “Every child has an inner timetable for growth—a pattern unique to him. . . . Growth is not steady, forward, upward progression. It is instead a switchback trail; three steps forward, two back, one around the bushes, and a few simply standing, before another forward leap.”
    —Dorothy Corkville Briggs (20th century)
