Identifies each week how many days behind or ahead your project is to date.
This graph quantifies, in days , the lag (positive or negative) that our project has each week , according to the periods of the S curve .
In this way, each week the gap will be calculated as follows:
The project offset will always answer the question:
"According to my baseline, how long ago was the current real progress due?"
In the image: T1 and T2 represent dates of different moments of the project:
- T2: Represents the date of the current moment of the project (current week).
- T1: This value is obtained by extrapolating over time the value that represents the real progress in T2 over the baseline.
Therefore, the offset is defined as:
Offset = T1 - T2
The subtraction is done in calendar days and the result is expressed in days.
