Types of S-curves

An S-curve is graphed on an X-Y graph with the X axis representing time, and the Y axis representing a quantity, usually Man Hours or Cost. The three basic types of S‑curves this White Paper will cover include:

1. Baseline S-curves
   These S-curves are generated from the Baseline Schedule and/or Baseline Fields in the Production Schedule.
    
2. Target S-curves
   These S-curves are generated from the Production Schedule, assuming all Tasks are completed as scheduled.
    
3. Actual S-curves
   These S-curves are also generated from the Production Schedule, using Task % Complete values to date. Actual S‑curves may also be referred to as Progress or Progress To Date S‑curves.

S-curve Quantities

Each of the above S-curves may represent any of the following on the Quantity (Y) axis:

• Any measurable quantity, such as volume of concrete placed, piles driven, etc.
• Man Hours planned/spent
• Cost budgeted/incurred

S-curve Quantity Units

Each of the above S-curves may use one of the following units for the values on the Quantity (Y) axis:

• Absolute Values for Man Hours and/or Cost
• Percentage Values for Man Hours and/or Cost
