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:

    “There must be a solemn and terrible aloneness that comes over the child as he takes those first independent steps. All this is lost to memory and we can only reconstruct it through analogies in later life....To the child who takes his first steps and finds himself walking alone, this moment must bring the first sharp sense of the uniqueness and separateness of his body and his person, the discovery of the solitary self.”
    —Selma H. Fraiberg (20th century)
