- The project accumulates contradictory documents and the model cites an obsolete plan
- Maintain a dated decision log, mark superseded artifacts, and refresh a short canonical brief before major work.
- A confident forecast hides unrealistic utilization, staffing, pricing, or cost assumptions
- Keep calculations in a transparent model, run downside scenarios, and reconcile projections with quotes and actuals.
- The model misreads a lease, permit, ordinance, tax, or insurance requirement
- Use AI to organize questions, then verify current primary documents with the responsible agency or qualified professional.
- Detailed synthetic personas are mistaken for measured local demand
- Label them hypotheses, recruit representative customers, and update the plan with observed behavior and willingness to pay.
