Project cost control · compared with Spreadsheets

Project cost control without spreadsheets

"Where is the programme overrun coming from?" is the question programme finance and PMO leads ask. With spreadsheets, the first answer takes hours, and the same hours again every month. Here is what each approach takes, and when spreadsheets are still the right choice.

What the job needs

The question

Where is the programme overrun coming from? Asked by programme finance and PMO leads, every month.

The data

The budget by workstream, actuals, purchase orders, forecast and change requests.

The answer

Budget, committed, actual and estimate at completion by workstream, with contingency drawn and the changes behind the overrun.

With spreadsheets

  1. Export the data and paste it into the workbook
  2. Rebuild the lookups and formulas for the new period
  3. Check the totals by hand
  4. Repeat next month

From the files you already export

  1. Export the budget, actuals, purchase orders and change log
  2. Map them once to workstreams and work packages
  3. Ask where the overrun comes from; the bridge from baseline to completion comes back
  4. Rate card exceptions and contingency drawdown sit beside it

Questions about project cost control

Can project cost control be done in spreadsheets?

Yes, and for a one-off question that will not come back they are often enough. The cost is the rebuild: hours, and the same hours again every month. The measures and the checks have to be redone by hand each period.

What data does project cost control need?

Usually the budget by workstream, actuals, purchase orders, forecast and change requests. Covirage reads those exports directly and maps the columns once.

What comes back when I ask "Where is the programme overrun coming from?"

In Covirage, budget, committed, actual and estimate at completion by workstream, with contingency drawn and the changes behind the overrun. Our tools compute it and check that it reconciles; the AI model explains it.
