Schedule Integrity, Summary and Detail Tasks, Milestone Tasks | PART 3

In Part 1 of this paper, I described the essence of S‑curves and their value. In this Part 2 I shall reveal how S‑curves can be generated.

How is an S‑curve Generated?

To generate a Baseline S‑curve, a Baseline Schedule is required, or a Production Schedule containing the Baseline dates and values of the original Tasks.

The Baseline Schedule/Production Schedule should contain the following information for each Task:

  • Baseline Start Date, Finish Date
  • Baseline Man Hours and/or Cost

To generate Actual and Target S‑curves, a Production Schedule is required.

The Production Schedule should contain the following information for each Task:

  • Start Date, Finish Date (if actual dates are unknown, Baseline / estimated dates should be used)
  • Man Hours and/or Cost (if actual values are unknown, Baseline / estimated values should be used)
  • % Complete (as of the Cut Off Date)

If a Baseline S‑curve is also to be generated with the Actual and/or Target S‑curves, the Production Schedule should also contain Baseline dates and values for each original Task in the appropriate Baseline Fields. This is usually the case if the Baseline Schedule was baselined, and copied to create the original Production Schedule.
