Example of a well thought out TPM
Est. at Completion
Worst Case Est.
Worst Case Estimate
(WCE) Measured or estimated progress to be compared with planned progress. WCE accounts for contingency (see below)
Estimate at Completion
Forecasted WCE value of a TPM at designated completion
Planned profile
Time phased expected values (based on prior experience)
Tolerance Band
Management control limits representing projected level of error or control within the process
Goal (Target)
Desired objective profile values; Usually set to allow design trade space between Goal and Threshold
Threshold
Limiting acceptable profile values, usually the required or specified values
Variance
Difference between the Planned Profile and WCE
Margin
Difference between the WCE and Threshold value
