CAPM Practice: Determine how to document project controls of predictive, plan-based projects

Standardized subcontractor cost reporting provides actual cost data in a format that can be entered into the EVM system, compared to earned value, and used to calculate CPI. Consistent formats enable meaningful comparison across multiple subcontractors and simplify invoice verification. This is a fundamental cost control practice in projects with multiple external vendors.

**Why not A:** While subcontractor cost reports may incidentally support risk management by revealing performance trends, documenting subcontractor performance for risk purposes is not the primary reason for requiring standardized monthly cost reports. The direct purpose is cost control and EVM calculation.

**Why not C:** Monthly cost reports in a specified format primarily provide cost data, not schedule completion data. Schedule control requires tracking work progress against planned milestones, which is a different type of reporting than cost reporting.

**Why not D:** Requiring subcontractors to submit cost reports is a control mechanism, not a stakeholder engagement activity. Stakeholder engagement involves communication strategies to maintain buy-in and satisfaction, not mandatory financial reporting formats.
