Quick Answer
The answer is the Control Costs process. This is correct because Control Costs is the project management process specifically designed to monitor cost performance, analyze variances from the cost baseline, and manage changes to the budget. When actual costs consistently exceed planned costs, this process enables the project manager to perform earned value management (EVM) calculations—such as cost variance (CV) and cost performance index (CPI)—to quantify the deviation and determine if corrective action is needed. On the CompTIA Project+ PK0-005 exam, this question tests your ability to map a real-world scenario to the correct process group and knowledge area; a common trap is confusing Control Costs with Monitor and Control Project Work, which is broader and not cost-specific. Remember the memory tip: if the problem involves dollars and a baseline, think "Control Costs" for the variance analysis.
This PK0-005 practice question tests your understanding of project management concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During project execution, the project manager notices that actual costs are consistently higher than planned. Which process should the project manager use to analyze this variance?
Plan Cost Management
Why wrong: This is planning, not monitoring.
Control Costs
Control Costs process analyzes cost variances.
Estimate Costs
Why wrong: Estimation is done before execution.
Determine Budget
Why wrong: Budget setting is part of planning.

Correct answer & explanation
Control Costs
The Control Costs process is responsible for monitoring cost performance, analyzing variances from the cost baseline, and implementing corrective actions. Since the project manager observes actual costs exceeding planned costs, they must use Control Costs to perform earned value management (EVM) calculations such as cost variance (CV) and cost performance index (CPI) to quantify and analyze the deviation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Plan Cost Management
Why it's wrong here
This is planning, not monitoring.
Control Costs
Why this is correct
Control Costs process analyzes cost variances.

Estimate Costs
Why it's wrong here
Estimation is done before execution.
Determine Budget
Why it's wrong here
Budget setting is part of planning.
Common exam traps
The trap here is that candidates confuse the planning processes (Plan Cost Management, Estimate Costs, Determine Budget) with the monitoring and controlling process (Control Costs), mistakenly selecting a planning process to analyze execution-phase variances.
Detailed technical explanation
Control Costs uses earned value management (EVM) metrics like CV = EV - AC and CPI = EV / AC to determine whether the project is under or over budget. A negative CV or CPI less than 1.0 indicates cost overruns, prompting root cause analysis such as examining resource rates, scope creep, or vendor performance. In practice, the project manager might also use variance analysis at the work package level to identify specific activities driving the overrun.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
