Project Management with SAP R/3
Measurement technique used in determining the percentage of completion (POC) in progress analysis.
In the time proportional method, the POC is calculated in relation to elapsed time in the project. The assumption is that project progress is linear over time.
You can use this measurement technique when you have short reporting periods or for activities such as consulting or administrative tasks.
