For the past couple of months, I've been analyzing a database which indicates the performance of our work force in the field. I've been looking for the right way to determine our productivity savings by determining a base comparative period that needs to meet the following criteria:
- At least 3 weeks of historical input data
- At least 10 counts of input data.
For the determination of our productivity savings we're taking the average performance between the first week of input data and all the performance reports till we meet the criteria previously mentioned, but I've struggled to find a formula that identifies that time period for every activity and generates the average performance.
The following screenshots are my current status:
I've tried using IF(AND(DISTINCTCOUNT('weeks'), COUNT('activity') in a SUMMARIZE table, but i could only get the first week number when data was recieved.
Hope someone knows how to help, thanks!
