Project Estimation Accuracy and Cost Overrun Risk
Definition
Custom machinery projects are complex, involving engineering, procurement, manufacturing, assembly, testing, and customer integration. Multiple sources of estimation error plague projects: (1) scope creep from customer requirement changes (10-20% typical), (2) procurement delays (2-8 weeks beyond estimate due to supply chain issues), (3) engineering rework when design assumptions prove incorrect (5-15% of schedule), (4) manufacturing inefficiencies and material waste (3-10% of cost), (5) customer-side delays in installation/integration (weeks to months), (6) quality issues discovered late in cycle requiring rework. Result: 40-60% of projects experience 10-25% cost overruns or schedule delays. For fixed-price contracts, this directly reduces profitability. For time-and-materials, it damages customer relationships and competitive position. Project managers lack visibility/tools to track actual vs. estimated costs and schedule in real-time, so problems discovered too late for mitigation.
