Budgets fail when hours, price and dates are worked out in three places. This workbook ties them together: hours by phase and level become a standard fee, the standard fee is compared with the proposed fee, and the phases are laid on a calendar against the report release date.

What it is

Budgets fail when hours, price and dates are worked out in three places. This workbook ties them together: hours by phase and level become a standard fee, the standard fee is compared with the proposed fee, and the phases are laid on a calendar against the report release date.

It shows realization at the proposed fee, the blended and effective hourly rates, the fee needed to reach your target realization, hours per calendar week by phase, overlaps and float. A worked example with illustrative numbers and live formulas sits on the Instructions sheet.

Questions

What is realization?

The fee divided by the standard value of the hours at your standard rates. The workbook computes it for the proposed fee and shows the gap to your target.

Why does fee by level have to equal fee by phase?

They are the same total built two ways: row by row and column by column. If they differ, a formula range has been broken. The sheet shows a red check.

How should hours be split by level?

Use the history of similar engagements. Partner hours at planning, review and reporting; manager hours at review; staff hours at fieldwork. Check the share-of-hours row against your usual mix.

What does negative float mean?

The last phase ends after the target report release date. Shorten a phase, start earlier, add staff or move the target.
