Topic snapshot

What this topic is really testing

Performance Analysis questions test whether you can turn project-control data into a defensible interpretation. Expect scenarios where the formula is only the first step: the answer still has to explain variance cause, trend, forecast effect, risk, corrective action, and communication to the right stakeholder.

Common CCP traps in this topic

• Reporting CPI or SPI without explaining what caused the variance.
• Mixing status-date data with outdated baseline or forecast information.
• Assuming a current efficiency trend applies to all remaining work.
• Ignoring near-critical schedule risk when the cost result looks acceptable.
• Choosing a recovery action that fixes the metric but creates cost, quality, contract, or stakeholder risk.

Sample questions

These questions are original PM Mastery practice items aligned to this topic area. They are designed for self-assessment and are not official exam questions.

Question 1

Topic: Performance Analysis

A cost professional is advising a plant manager on how to compare two alternatives for the same required pumping service. The owner has not set a fixed retirement date for the facility, uses an 8% time-value rate, and wants the recommendation expressed as a cost per year of service.

Which economic-analysis method should be used as the primary basis for the recommendation?

• A. Use internal rate of return on the new pump as a stand-alone capital investment.
• B. Use initial capital cost only because both alternatives provide the same pumping service.
• C. Use simple payback based on the new pump’s annual O&M savings versus the added capital.
• D. Use equivalent annual cost at 8%, including capital recovery, O&M, and residual value.

Best answer: D

What this tests: Performance Analysis

Explanation: When alternatives provide the same service but have different service lives, recurring operating costs, and residual values, the analysis should account for the full lifecycle cash-flow pattern and the time value of money. Because management wants the result stated as a cost per year of service and there is no fixed study-period endpoint, equivalent annual cost is the best primary method. It annualizes each alternative’s capital recovery, annual O&M, and terminal value using the 8% rate, allowing a consistent comparison despite the 4-year and 10-year lives. The result supports a replacement decision without relying on first cost or a partial savings measure.

Equivalent annual cost fits equal-service alternatives with unequal lives and converts lifecycle cash flows into the requested annual cost basis.

Question 2

Topic: Performance Analysis

A construction project is 8 calendar days late against a contractual turnover milestone at the data date. Liquidated damages for missing the milestone are $35,000 per day. The superintendent proposes weekend and night-shift overtime for electrical terminations, estimates a $210,000 direct labor premium, and says it will recover all 8 days.

Before approving, project controls notes four constraints:

• The proposal excludes $75,000 for night supervision, temporary lighting, and additional inspections.
• Recent overtime in the same congested area reduced labor productivity by about 15%.
• Electrical quality hold points cannot be bypassed.
• The contract requires owner approval for compensated acceleration and changed work hours.

What is the best professional action?

• A. Do not accept the proposal as presented; prepare an integrated recovery analysis including indirect cost, productivity, quality coverage, and owner-approval requirements.
• B. Start the overtime because the $210,000 labor premium is less than the $280,000 potential liquidated damages.
• C. Update the baseline milestone to the proposed recovered date and report the added cost as a forecast issue.
• D. Approve only the added direct labor, then track supervision, lighting, and inspection costs as normal indirect budget variances.

Best answer: A

What this tests: Performance Analysis

Explanation: A recovery action that appears attractive on a direct-cost comparison can be misleading. The direct overtime premium of $210,000 is less than the potential $280,000 liquidated damages exposure, but the excluded $75,000 of support costs nearly eliminates that apparent benefit before considering productivity loss, added inspection coverage, rework risk, or failure to recover the full 8 days. Because quality hold points cannot be bypassed, the recovery plan must preserve inspection and acceptance requirements. Because the contract requires owner approval for compensated acceleration and changed work hours, implementation without approval can create unrecoverable cost or contractual dispute. The cost professional’s role is to provide an integrated cost/schedule recovery analysis with assumptions, risks, and approval needs clearly stated.

The apparent schedule recovery must be tested against total cost, forecast reliability, quality constraints, and contractual approval before acceleration is recommended.

Question 3

Topic: Performance Analysis

A cost engineer is reviewing a pipeline installation control account at the monthly data date. The control budget is 10,000 linear feet at $120 per linear foot. No scope change has been approved.

Which corrective action is best supported by the exhibit?

• A. Report 5,000 earned linear feet because that was the planned quantity, and treat the cost overrun as a timing difference until next month.
• B. Maintain the approved baseline, report earned progress from 4,000 accepted linear feet, remove the staging constraint, and update the ETC/EAC using current productivity until recovery is verified.
• C. Hold the EAC at the control budget and authorize overtime immediately so the schedule performance index can return to plan.
• D. Reset the control baseline to the actual installed quantity and move the equipment-setting logic so the cost and schedule variances are removed.

Best answer: B

What this tests: Performance Analysis

Explanation: The exhibit shows both schedule and cost underperformance driven by field productivity. Planned progress is 5,000 linear feet, but only 4,000 accepted linear feet have been earned, and actual cost is already above the earned value implied by the budget rate. The field note identifies a correctable production constraint: material staging congestion. A sound corrective action should keep the approved baseline intact, measure earned value from accepted physical progress, coordinate with field and scheduling to remove the constraint, and update the forecast using demonstrated productivity until recovery is proven. Changing baseline dates, forcing earned progress, or holding the forecast at budget would make reporting look better but would not solve the performance driver or support reliable decision-making.

This addresses the demonstrated productivity driver while preserving baseline integrity and forecast credibility.

Question 4

Topic: Performance Analysis

A cost engineer is asked whether the September performance report for a construction control account is reliable enough for an executive cost review. The approved BAC is $5,500,000.

Supporting file notes:

• Progress quantities were frozen on Sep. 25, not Sep. 30.
• Accounting export through Sep. 30 shows AC of $3,746,900; no accrual reconciliation is attached.
• The procurement log lists a pending $430,000 field change dated Sep. 29.
• Last month’s forecast included a $210,000 trend; the current report removes it with no closure record.

Which professional judgment is best supported?

• A. Report a favorable cost position because the current forecast removed last month’s trend exposure.
• B. Accept the report because the CPI is nearly 1.00 and the EAC is below the approved BAC.
• C. Treat the report as not yet decision-ready because the precise EAC lacks reconciled source evidence and consistent timing.
• D. Exclude the pending field change because it has not been approved and therefore cannot affect forecast credibility.

Best answer: C

What this tests: Performance Analysis

Explanation: A performance report can look authoritative when it presents exact values, but credibility depends on traceable, time-consistent, reconciled source data. Here, the report uses a Sep. 30 status date while progress quantities were frozen five days earlier. The reported actual cost does not reconcile to the accounting export, and no accrual bridge is provided. A pending field change and an unexplained trend removal also affect forecast reliability. The cost engineer should not treat the detailed EAC as decision-ready until the audit trail supports it. The appropriate professional response is to qualify the report, reconcile source timing and actual cost, and resolve change or trend status before executives rely on the forecast.

The apparent precision is undermined by cutoff differences, unreconciled actual cost, pending change exposure, and an unsupported trend removal.

Question 5

Topic: Performance Analysis

At the data date, a mechanical installation control account is 10 workdays behind the integrated schedule. The project manager asks whether the proposed recovery plan should be approved for the next cost report.

Recovery note:

• Proposal: add a night shift and Saturday overtime for 4 weeks.
• Direct premium included in proposal: $96,000.
• Schedule effect claimed: recover 8 of the 10 late workdays.
• Costs not included: extra field supervision, QA/QC inspection, temporary lighting, safety coverage, and equipment standby.
• Current workface: two subcontractors already share the same congested area.
• Recent trend: craft hours above 50 per week reduced installed-unit productivity by 12% and increased weld rework.
• Contract condition: owner approval is required before changing shift patterns or billing acceleration costs.

What should the cost professional recommend?

• A. Report the 8-day recovery now but defer indirect costs and productivity loss until actuals confirm them.
• B. Hold approval and rework the recovery forecast to include indirects, productivity and quality impacts, and owner authorization.
• C. Approve the plan using the $96,000 premium because it recovers most of the schedule slip.
• D. Rebaseline the control account to the recovery schedule so progress is measured against the new plan.

Best answer: B

What this tests: Performance Analysis

Explanation: A recovery action should not be judged only on its direct labor premium or claimed schedule gain. In cost and schedule integration, the forecast must reflect the full cost and execution effect of the corrective action. Here, the proposal excludes field indirects and support costs, assumes no productivity degradation despite congestion and recent overtime evidence, and ignores increased quality risk from rework. It also cannot be implemented or billed as acceleration without owner approval. The professional response is to treat the plan as incomplete, revise the recovery forecast with these effects, and obtain the required authorization before recommending approval or reporting the recovery as credible.

The exhibit shows that the attractive direct-cost recovery case omits material cost, productivity, quality, and contractual constraints.

Question 6

Topic: Performance Analysis

A cost engineer is reviewing a refinery shutdown control account at the data date. The base EAC already reflects approved scope, actuals, commitments, and approved changes through the data date. Open trends are probable cost impacts being evaluated but not yet approved as changes. No baseline change or management-reserve release has been authorized since last month. Which interpretation/action is best supported by the status exhibit?

• A. Report only the $48.8M base EAC, noting that trends and residual risks are not approved changes.
• B. Report a $51.3M risk-adjusted forecast, a $1.7M adverse movement, and escalate the $1.3M control-budget exposure.
• C. Move $1.3M of management reserve into the control budget and report the account as on budget.
• D. Report the account as within budget because the base EAC is below $50.0M and $1.2M contingency remains.

Best answer: B

What this tests: Performance Analysis

Explanation: Risk-adjusted performance should separate forecast insight from budget authority. The current base EAC is $48.8M, but expected open trends and residual risks add $2.5M, making the risk-adjusted forecast $51.3M. Compared with the prior risk-adjusted forecast of $49.6M, the adverse movement is $1.7M. The approved control budget is $50.0M, so the expected risk-adjusted position is $1.3M over the control budget; equivalently, the $1.2M remaining contingency is insufficient for the $2.5M expected exposure. Because management reserve is outside the control budget and requires sponsor approval, the professional action is to report the risk-adjusted forecast transparently, validate and process the trend exposure, and escalate the reserve or funding decision rather than absorb it silently or rebaseline without authority.

Base EAC plus expected trend and residual-risk exposure equals $51.3M, leaving a $1.3M expected overrun that may require approved reserve action.

Question 7

Topic: Performance Analysis

A cost engineer is preparing an updated EAC for a refinery revamp piping control account at the data date. The account is 62% physically complete and has a CPI of 0.84. The project manager needs a forecast for a funding review tomorrow.

Constraints:

• The approved control budget is still valid; no scope change has been approved.
• Actual costs and accruals are complete through the data date.
• The remaining work is mainly 3,800 field welds in congested tie-in areas.
• The contractor proposes adding a second crew, but access permits for the tie-in areas are not yet confirmed.

Which remaining-work fact is most important to confirm before relying on the ETC?

• A. The achievable weld productivity for the remaining tie-ins, including confirmed crew access and availability
• B. The overall project CPI across all control accounts
• C. The total cash paid to the contractor through the data date
• D. The original budgeted unit rate used for the completed weld quantities

Best answer: A

What this tests: Performance Analysis

Explanation: Forecast reliability depends on the quality of the assumptions for the work still remaining, not only on past performance. In this case, the remaining scope is concentrated in field welds under constrained access conditions, and the proposed recovery depends on a second crew that may not be able to work. Even with complete actual costs and a valid baseline, the ETC could be materially wrong if it assumes productivity or crew availability that cannot be achieved. Past CPI is useful context, but the decisive forecast input is the productivity basis for the remaining welds under the actual access and crew constraints.

The ETC depends most on whether the remaining weld work can actually be performed at the assumed productivity with the crews and access available.

Question 8

Topic: Performance Analysis

At the June data date, the cost engineer is preparing the control account report for a piping installation package. All amounts are USD.

Constraints:

• Earned value must be based on approved installed-quantity progress.
• Actual cost must include paid costs plus accruals for accepted work through the data date.
• The baseline may be changed only through approved change control; no approved change exists.

The schedule update shows 55% physical completion versus 60% planned. The draft dashboard uses ledger actual cost only, shows CPI = 1.34, and labels the account as a cost underrun. What is the best action before the report is issued?

• A. Issue the dashboard using ledger actual cost, describe the account as a cost underrun, and wait for supplier invoices before changing actual cost.
• B. Charge the full 630,000 remaining open commitment to actual cost, report the account as severely overrun, and request immediate funding.
• C. Reset planned and earned value to match the posted ledger actual cost, remove the schedule variance, and defer variance reporting until change control acts.
• D. Revise actual cost to include the 410,000 accepted-work accrual, keep planned and earned value unchanged, and report the schedule slip and accrued cost overrun with a reconciliation note.

Best answer: D

What this tests: Performance Analysis

Explanation: Conflicting cost-control records should be reconciled before performance is interpreted. Ledger actual cost, commitments, accruals, and physical progress are related but not interchangeable. In this case, the ledger-only actual cost understates incurred cost because accepted work through the data date has not been accrued. Including that accrual changes the cost view from apparently favorable to unfavorable. The remaining open commitment is still exposure for unperformed or unaccepted work, not actual cost. Earned value should remain based on approved installed quantities, and planned value should remain tied to the approved baseline unless an approved change modifies it. Because earned value is below planned value, the schedule slip is a real performance issue, while the favorable CPI from ledger actuals is a data reconciliation issue.

Accepted work must be accrued in actual cost, while earned value and planned value remain tied to measured progress and the approved baseline.

Question 9

Topic: Performance Analysis

At the July data date, a cost engineer is preparing the monthly cost report for a construction control account. Amounts are in thousands of dollars.

• Cost status:
  • BAC: 4,000
  • Earned value (EV): 2,200
  • Actual cost (AC): 2,530
  • Prior-month EAC: 4,300
  • Current EAC: 4,560
• Management thresholds:
  • Variance explanation: CV% = (EV - AC) / EV, triggered when worse than -10%.
  • Sponsor escalation: forecast movement = (Current EAC - Prior-month EAC) / Prior-month EAC, triggered when greater than +5%.
  • Baseline review: (Current EAC - BAC) / BAC, triggered when greater than +15%.

Which interpretation and management action is best supported by the report?

• A. Take no threshold action because the EAC overrun is less than 15% of BAC.
• B. Start the baseline review and defer sponsor escalation until the baseline is revised.
• C. Prepare only the cost variance explanation; the EAC movement is still within threshold.
• D. Prepare the cost variance explanation and escalate the EAC movement; the baseline review threshold is not crossed.

Best answer: D

What this tests: Performance Analysis

Explanation: Each management threshold should be tested against its own rule. The cost variance percentage is \((2,200 - 2,530) / 2,200 = -15\%\), which is worse than the -10% trigger, so a variance explanation is required. The forecast movement is \((4,560 - 4,300) / 4,300 \approx +6.0\%\), which is greater than the +5% sponsor escalation trigger. The forecast overrun against BAC is \((4,560 - 4,000) / 4,000 = +14\%\), which does not exceed the greater-than-15% baseline review threshold. The supported action is therefore to explain the unfavorable cost performance and escalate the forecast movement, while avoiding an unsupported baseline review action.

CV% is about -15% and EAC movement is about +6%, while the EAC overrun is +14%, so only the first two thresholds are triggered.

Question 10

Topic: Performance Analysis

At the 30 Jun data date, a cost engineer reviews the control-account performance report for structural steel before it is issued. Company procedure requires earned value to be supported by approved installed quantities, actual cost to include incurred work through the data date including accruals, and forecast changes to retain a trend or change reference.

Structural steel control account
BAC: $2,500,000
PV at 30 Jun: $1,600,000
Reported EV: $1,700,000, based on manual progress entry of 68%
QA-verified installed quantity: supports 52% completion
AC loaded: $1,520,000, accounting feed posted through 15 Jun
Unaccrued 16-30 Jun subcontractor work: $220,000 estimated
Cost coding: $180,000 steel cost posted to civil account, transfer pending
Forecast: EAC manually reduced from $2,450,000 to $2,200,000; no trend/change reference

Which interpretation is the best professional judgment?

• A. The CPI and EAC should be treated as unreliable until actuals, accruals, cost coding, supported progress, and the forecast override are reconciled.
• B. The field progress entry should be retained because it produces an EV consistent with the current plan and avoids a baseline change.
• C. The account is underrunning because EV exceeds PV and AC, so the reduced EAC can be issued as the current forecast.
• D. The report is usable if the steel coding transfer is made; the other items affect accounting timing but not performance analysis.

Best answer: A

What this tests: Performance Analysis

Explanation: Performance analysis depends on current, consistent, and traceable data. In this control account, both sides of the CPI calculation are compromised: EV is based on a manual 68% progress entry even though verified installed quantities support only 52%, and AC is incomplete because the accounting feed is stale, accruals are missing, and steel cost is coded to the wrong account. The EAC is also suspect because it was manually reduced without a trend or change reference. Publishing favorable CPI or EAC values from these inputs would give stakeholders false confidence. The professional response is to reconcile the performance data, restore auditability, and then interpret variance and forecast results.

The report contains stale actuals, missing accruals, misclassified cost, unsupported earned progress, and an unaudited EAC override.
