Cost Estimation: Effort Drivers, Magnitude Indicators & Investment Framing
Cost driver identification — effort inductors, scope drivers, magnitude estimation, team composition modeling, risk-adjusted timeline ranges, service engagement sizing, consulting effort, automation ROI, and staffing model. Use when the user asks to "estimate effort", "identify cost drivers", "size the project", "plan team composition", "identify effort inductors", or mentions WBS, sizing, contingency, burn rate, PERT, Monte Carlo, or "Phase 4" cost work. NEVER produces final prices — produces drivers, ranges, and magnitude indicators with costing disclaimers.
