Comparing Sectors and Performance Measurement Problems in ACCA PM

Updated 11 October 2026 · Fact-checked

Private sector firms mainly pursue profit and shareholder wealth, so performance is largely financial and easy to measure. Public sector and not-for-profit bodies pursue service goals for many stakeholders, with outputs that are hard to quantify. To compare, identify objectives, stakeholders and measurable outputs, then explain the limits of each measure.

Understand Comparing Sectors and Performance Measurement Problems

Every organisation needs performance measures, but what counts as good performance depends on its purpose. A private sector company exists mainly to make profit for its owners. Profit, return on capital and growth are clear, numerical and comparable.

A public sector body, such as a state hospital or local council, is funded by government or taxes. It exists to deliver services to citizens. A not-for-profit (NFP) organisation, such as a charity, exists to meet a social cause. It may be funded by donations and grants. Neither has profit as its main aim, although both must still use money well.

The key difference is stakeholders and objectives. A company has shareholders, lenders, staff and customers, and the shareholder interest usually dominates. A public body answers to taxpayers, service users, government, staff and regulators. A charity answers to donors, beneficiaries, trustees and volunteers. These groups want different things, so there are multiple objectives that can conflict, for example shorter waiting times versus lower cost.

This creates measurement problems. Outputs are often non-quantifiable: how do you put a number on a pupil's education, a patient's wellbeing or public safety? Outcomes may appear years later. Inputs are easy to count, outputs are not. There may be no market price, no competitors to benchmark against and no profit as a single summary figure. Targets set by government may also push staff to hit the number rather than the real aim.

So comparison across sectors needs care. You cannot use profit or ROI for a charity. Instead use value for money: economy (low cost of inputs), efficiency (output per unit of input) and effectiveness (achieving the objectives). Also use non-financial indicators and qualitative judgement, and say clearly where they fall short.

Key rules to remember

Economy: Economy = spending less on inputs of the right quality; Looks at the cost of resources bought. Example: cost per hour of nursing staff.
Efficiency: Efficiency = outputs ÷ inputs; Output per unit of resource used. Example: patients treated per nurse hour.
Effectiveness: Effectiveness = degree to which outputs achieve the stated objectives; Compares results with the aim, such as improved health outcomes. It is often qualitative.
Sector contrast rule: Private: profit and shareholders. Public and NFP: service objectives and many stakeholders; Use this as the starting frame for any comparison answer.

How to solve Comparing Sectors and Performance Measurement Problems questions

Use this method for any question that asks you to compare sectors or discuss measurement problems.

1Read the scenario and name the sector or sectors involved.
2State the main objective of each organisation, and note any secondary or conflicting objectives.
3List the key stakeholders and what each wants.
4Identify what the organisation produces and which outputs can be measured and which cannot.
5Link each problem to the scenario: multiple objectives, non-quantifiable outputs, no profit measure, no market competition, funding limits or political targets.
6Suggest suitable measures such as value for money, cost per unit of service and non-financial indicators, and say what each misses.
7Finish with a short conclusion or recommendation that answers the exact requirement.

Quickest way: Objective, stakeholder, output, measure

When to use it: Use it for short objective test questions and to plan a written answer in a couple of minutes.

Write O, S, M, P on your scratch pad: Objectives, Stakeholders, Measures, Problems.
For each sector, jot one phrase per letter.
Match the question to one letter and answer from that line.
For written answers, turn each letter into a paragraph with a scenario example.

Common mistakes in Comparing Sectors and Performance Measurement Problems

Saying public sector and NFP organisations have no financial objectives.
Students think non-profit means no money matters.
Fix: Say they must still stay within budget and use funds well. Money is a constraint, not the main aim.
Using profit or ROI as the main measure for a charity or public body.
Private sector measures are the most familiar.
Fix: Switch to value for money and service-based indicators, and explain why profit is unsuitable.
Listing generic problems without linking them to the scenario.
Students memorise a list and write it out.
Fix: Tie each problem to a named output in the scenario, such as a hospital's patient outcomes.
Treating efficiency and effectiveness as the same thing.
Both sound like doing well.
Fix: Efficiency is output per input. Effectiveness is whether the objective was achieved. A body can be efficient but ineffective.
Ignoring the multiple stakeholders and their conflicting aims.
Students focus on one group, usually users.
Fix: Name at least two stakeholder groups and show how their interests conflict.

Worked examples

Example 1

A city council runs a free public library service. Explain two problems in measuring its performance compared with a private bookshop.

Show the solution

The bookshop has a clear objective: profit. Revenue, margin and ROI are easy to measure.
Problem 1, multiple objectives: the library aims to promote literacy, give community access and stay within budget. These can conflict, and no single figure summarises success.
Problem 2, non-quantifiable outputs: the benefit of reading, learning and community value is hard to measure. Counting books lent measures activity, not benefit.
Also there is no sales price, so revenue cannot show how users value the service.

Answer: The bookshop is judged on profit. The library faces multiple, possibly conflicting objectives, and its main outputs are qualitative and have no market price, so value for money and user surveys are needed alongside cost per loan.

Example 2

A charity spends ₹40,00,000 on a literacy programme and 2,000 adults complete it. Last year it spent ₹33,00,000 and 1,650 adults completed it. Calculate cost per completer for each year and comment on what the figures do not show.

Show the solution

This year: ₹40,00,000 ÷ 2,000 = ₹2,000 per completer.
Last year: ₹33,00,000 ÷ 1,650 = ₹2,000 per completer.
Cost per completer is unchanged, so efficiency in cost terms is the same.
Limitations: completion is an output, not an outcome. The figures do not show whether reading skills improved, the quality of teaching or the difficulty of the learners.
Effectiveness needs measures such as test results or later employment, which are harder to collect.

Answer: Cost per completer is ₹2,000 in both years. This shows stable efficiency but says nothing about effectiveness, because quality and long-term benefit are not captured.

Exam tips

Always name the sector's main objective first. It sets up everything else in your answer.
Link each measurement problem to the scenario facts. Generic lists earn little.
Use the three Es precisely and do not mix up efficiency and effectiveness.
In objective tests, watch for options that apply profit measures to public or NFP bodies. These are usually wrong.
For discussion questions, give a balanced view: say what a measure does show and what it misses.

Comparing Sectors and Performance Measurement Problems: frequently asked questions

What are the main differences between private, public and not-for-profit performance measurement?

Private firms focus on profit and shareholder return, which are numerical and comparable. Public and NFP bodies focus on service objectives for many stakeholders. Their outputs are harder to quantify, so measures are more varied and often qualitative.

What are the problems of performance measurement in the public sector?

Common problems are multiple and conflicting objectives, non-quantifiable outputs, no profit measure, no market price and political influence on targets. Measures can also distort behaviour if staff chase targets. Always link these to the scenario.

How do you compare performance across sectors?

Direct comparison is limited because aims differ. Compare against each body's own objectives, use value for money (economy, efficiency, effectiveness) and benchmark against similar organisations where possible. State the limits of any comparison.

Why is it hard to measure qualitative outputs in a not-for-profit organisation?

Outputs such as wellbeing, education or social change have no market price and may take years to appear. Surveys and case studies give evidence but are subjective and costly. Counting activity is easier but may not show real benefit.
