PK0-005 Project Management Concepts Practice Question
A project manager is evaluating the financial viability of several proposed projects. The steering committee wants to select projects that maximize return over time. Which TWO financial metrics should the project manager use to compare long-term profitability? (Select TWO).
⚠ Common exam trap
PK0-005 often tests whether candidates recognize that payback period and ROI ignore the time value of money — a common mistake is selecting ROI as a long-term profitability metric because it is familiar, but it does not discount future cash flows.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Net Present Value (NPV)
Net Present Value (NPV) is correct because it discounts all future cash inflows and outflows to present value using the organization's cost of capital, giving a direct dollar measure of the project's long-term value creation; projects with higher positive NPV maximize return over time. Internal Rate of Return (IRR) is correct because it expresses the discount rate at which a project's NPV equals zero, allowing comparison of projects' annualized percentage returns over their full life spans, which supports long-term profitability ranking. Payback Period is not marked correct because it only measures how quickly the initial investment is recovered and ignores cash flows after the payback date and the time value of money. Return on Investment (ROI) is not marked correct because it is a simple ratio of net benefits to costs that does not discount future cash flows or capture project duration. Cost-Benefit Analysis is not marked correct because it is a general appraisal framework rather than a specific discounted cash-flow profitability metric.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Net Present Value (NPV)
Why this is correct
Net Present Value discounts all future cash flows to today's value, directly satisfying the steering committee's requirement to maximise return over time. Unlike payback period, which ignores cash flows beyond the break-even point, NPV captures total long-term profitability across each project's full lifespan, making it the definitive metric for comparing financial viability.
- ✗
Payback Period
Why it's wrong here
Payback Period measures how quickly cumulative cash flows recover the initial investment, ignoring all returns after that point and the time value of money. It is tempting for liquidity or risk screening on short horizons. Long-term profitability comparison instead requires Net Present Value and Internal Rate of Return.
- ✗
Return on Investment (ROI)
Why it's wrong here
ROI expresses total net benefit as a percentage of cost, so it ignores when cash flows occur and cannot rank projects by absolute long-term value. It is tempting because it normalises returns across differing investment sizes. Comparing long-term profitability requires Net Present Value and Internal Rate of Return, which discount future cash flows.
- ✓
Internal Rate of Return (IRR)
Why this is correct
Internal Rate of Return discounts future cash flows to find the rate at which a project's net present value equals zero, so projects can be ranked by percentage yield regardless of scale. This directly satisfies the steering committee's goal of comparing long-term profitability across competing proposals, since IRR accounts for the time value of money over the full project lifespan.
- ✗
Cost-Benefit Analysis
Why it's wrong here
Cost-Benefit Analysis totals and compares costs against benefits, but without discounting it treats future cash flows as equal to present ones, so it cannot rank long-term profitability across projects. It is tempting as a broad feasibility check. Net Present Value and Internal Rate of Return apply discounting to future cash flows.
