How are people forecasting FUTURE total project costs and profit when actual hours/expenses are exceeding plan but you can't borrow planned hours from future tasks?
My company is a consulting agency that works for a fixed fee amount (vs say an attorney who just bills whatever hours they work). We plan hours and expenses to arrive at a price, and our clients pays that amount whether we work more or less than the plan.
Obviously not all projects go as planned, and some require more hours than planned. So I'm trying to determine how to forecast the eventual total project costs while mid project- this is generally done by adding the Actual hours and expenses to the remaining planned hours and expenses. (that is NOT the same as subtracting Plan from Actual)
Has anyone else solved this? How do others forecast fixed fee project costs or profitability before the project is complete?
