Plans improve only when they receive feedback
Teams often finish a project and immediately begin the next one. Without comparing forecast and actual effort, the same estimation bias follows them into every new plan.
Look beyond one variance number
Measure variance by phase, role, task type, project manager, and client. Patterns reveal whether the issue came from scope, estimation, staffing, or execution.
- Under-forecast effort creates delivery and margin risk
- Over-forecast effort hides reusable capacity
- Late timesheets make variance appear smaller than it is
- Repeated bias should change templates and assumptions
Use accuracy to build confidence
Forecast accuracy is not about blaming the estimator. It is a measure of how quickly the organization learns. Show the reason for a variance and record the corrective action used in the next forecast.
