Introduction
What is S - Curve:
Value Vs project time:
Planning Value – Planning progress value
Earned Value -- Actual progress value
Actual Value -- Actual Spent value
Why we use S-curve:
As a tool for project helthy check (status)
As a tool for control of schedule and cost
Forcast of completion ETC and EAC
What it is not:
Not only for the PM (but also for company level of schedule and cost monitoring)
Not the only project control tool (shall together with schedule control, cost control as well as man power plan etc.)

Set-up and use
Basis of S-curve
Basis of Data:
Cost baseline– Budget (BOQ with levels of WBS)
Input Data:
Progress data as percentage
TBD Standard Tool:
Already set as EPCM Tool :\\10.161.34.1\Public\Project Tools Matrix\EPCM Project Tools_02\Project Mangement\PM01 Project Plan

Set-up and use
How to Set- up
Line 1- Planning Value Intial setup Distribute budget Vs Time and consist with master schedule
Update of budget (only possible through approved DCN)
Line 2- Earned Value timely update Earned Value or Actual progress, udpated as percentage.
Line 3 – Actual Value Expenditure accumulated value ( invesigation cash flow)
Forecast of completion Estimate to completion (ETC )
Estimate at completion ( EAC)

Actual Cost :
- ahead of schedule ;
- under budget;
- is it a problem if AV>PV?
No! if EV>AV, it is may not be a problem.

Other Highlights
The S – Curve is currently majorly as tools used for
monitoring the schedule status in construction stage.
• For cost status including ETC,EAC etc., it is included in Detailed
Cost Report ( which is already as TBD standard EPCM document
)
• For schedule control, it will be detailed in schedule control process.
