Using labor rules is a great feature for CC managers. It allows them to focus on defining their team (existing and future) and leaves the financial calculations to the tool. To my surprise, CC managers demand a high level of accuracy of the OPEX calculation resulting from applying the labor rules to their team roster. Accuracy is defined as the gap between the OPEX calculation in ITPF and the OPEX calculation originating from the source of truth for financial data (Oracle in my context).

It may appear simple to calibrate the labor rules calculation. Step one is to reproduce in ITPF the business rules as defined in Oracle, step  two compare the opex results from both and adjust ITPF. Something is missing and I do not what.

After following the two steps above at the aggregate level (CIO roll up) the gap is under 0.02%. The target was shooting for under 1% so arriving at below 0.02% appear to be a great result. The surprise was looking at the gap at the sub-division level and arriving at variances over 10% in some cases. Obviously if one organization is looking at a large variance, some other organizations will be experiencing the opposite to arrive at a consolidated variance under 0.02%. But this does not help end users as they compile their plans and forecast. Or does it?

Curious to hear how others are solving this problem
