The standard for project management

Control thresholds. 

Variance thresholds for monitoring cost performance may be specified to indicate an 

agreed-upon amount of variation to be allowed before some action needs to be taken. Thresholds are typically 

expressed as percentage deviations from the baseline plan.

Rules of performance measurement. 

Earned value management (EVM) rules of performance measurement are 

set. For example, the cost management plan may:

u

n

Define the points in the WBS at which measurement of control accounts will be performed;

u

n

Establish the EVM techniques (e.g., weighted milestones, fixed-formula, percent complete, etc.) to be 

employed; and

u

n

Specify tracking methodologies and the EVM computation equations for calculating projected estimate at 

completion (EAC) forecasts to provide a validity check on the bottom-up EAC.
