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

ETC (using current CPI) = Remaining Planned Work / CPI. If remaining planned cost = $240,000 and CPI = 0.88, then ETC = $240,000 / 0.88 ≈ $272,727. This means even though $240,000 was planned for remaining work, at the current efficiency rate, the project will spend approximately $272,727 to complete that work — a $32,727 additional overrun on top of existing overruns.

**Why not A:** ETC can be calculated without knowing the explicit Actual Cost value when the remaining planned budget and CPI are known. The formula ETC = remaining budget / CPI uses the planned remaining cost and the current efficiency rate. AC is embedded in CPI but is not separately needed for this calculation.

**Why not B:** $211,200 would result from multiplying $240,000 by 0.88, which incorrectly applies CPI as a multiplier. Since CPI < 1.0 means the project is less efficient than planned, the remaining work will cost more, not less. You must divide by CPI, not multiply.

**Why not D:** Using the planned $240,000 assumes the remaining work will be completed at the originally planned efficiency (CPI = 1.0). With a CPI of 0.88, the project is demonstrably less efficient than planned, so assuming planned efficiency for remaining work ignores actual performance data.
