JSD Steps
When it was originally presented by Jackson in 1982, the method consisted of six steps
- Entity/Action Step
- Initial Model Step
- Interactive Function Step
- Information Function Step
- System Timing Step
- System Implementation Step
Later, some steps were combined to create a method with only three steps.
- Modelling Stage (Analysis): with the Entity/Action Step and Entity Structures Step.
- Network Stage (Design) : with the Initial Model Step, Function Step, and System Timing Step.
- Implementation Stage (Realisation) : The implementation Step.

Famous quotes containing the word steps:
“What had really caused the women’s movement was the additional years of human life. At the turn of the century women’s life expectancy was forty-six; now it was nearly eighty. Our groping sense that we couldn’t live all those years in terms of motherhood alone was “the problem that had no name.” Realizing that it was not some freakish personal fault but our common problem as women had enabled us to take the first steps to change our lives.”
—Betty Friedan (20th century)
