Value for Money and Performance Measurement in the Public Sector

Updated 11 October 2026 · Fact-checked

Value for money (VfM) asks whether a public body gets the best result from the resources it uses. You test it with three Es: economy (low cost of inputs), efficiency (best output per input) and effectiveness (outputs achieving the intended outcomes). In SBL, apply each E to the scenario's facts.

Understand Value for Money and Performance Measurement

Public sector bodies have no profit figure to show success. Profit tells a company whether it created value. A hospital, school or council needs another yardstick. Value for money is that yardstick. It asks whether public money was used well.

Value for money is judged using three tests, often called the 3Es.

Economy: buying inputs of the right quality at the lowest reasonable cost. It is about spending less on what you put in.
Efficiency: getting the maximum output from the inputs used, or using the minimum inputs for a given output. It links inputs to outputs.
Effectiveness: whether the outputs achieve the policy goals or outcomes. It links outputs to outcomes.

The tests can pull against each other. A cheap supplier (economy) may deliver poor quality, which hurts effectiveness. A very efficient process may produce an output nobody needs. A body can be economical and efficient yet ineffective. That is why you must assess all three together.

Measurement is the hard part. Inputs and outputs are often easy to count, such as cost per patient treated. Outcomes are harder, such as better public health or lower crime. Outcomes take years to appear, depend on many factors outside the body's control, and may be valued differently by different stakeholders. Many bodies also have several objectives that conflict, so no single measure is enough.

Some writers add a fourth E, equity (fairness of access and treatment), and sometimes ethics or environment. Use these only if the scenario raises fairness or access issues.

Key rules to remember

Economy: Economy = cost of inputs, compared with a benchmark or budget (spending less for the same quality); Link: inputs. Check quality is held constant, or low cost may be false economy.
Efficiency: Efficiency = outputs ÷ inputs (or cost per unit of output); Link: inputs to outputs. Example: cost per patient treated, pupils taught per teacher.
Effectiveness: Effectiveness = extent to which outputs achieve the intended outcomes or objectives; Link: outputs to outcomes. Compare actual outcomes with the stated target.
Value for money: VfM = economy + efficiency + effectiveness (assessed together); It is a judgement across the three, not a single number.

How to solve Value for Money and Performance Measurement questions

Use this method for any question on value for money or public sector performance.

1Identify the organisation, its objectives and its main stakeholders from the scenario. Public bodies have several objectives, so list them.
2Separate the facts into inputs (costs, staff, resources), outputs (services delivered) and outcomes (the real change achieved).
3Apply economy: are inputs bought at a sensible price and quality? Quote figures or facts from the case.
4Apply efficiency: compare outputs with inputs, over time or against similar bodies. Calculate a ratio if figures are given.
5Apply effectiveness: compare outcomes with stated objectives. Note if the outputs actually delivered the benefit intended.
6Explain interactions and trade-offs, for example cost cutting that harms quality, or efficiency that reduces access.
7Comment on measurement problems: hard-to-quantify outcomes, time lags, outside influences, and conflicting stakeholder views.
8Conclude with a clear judgement and a practical recommendation, such as better KPIs or benchmarking.

Quickest way: Inputs, outputs, outcomes in two minutes

When to use it: Use when time is short and the question asks you to assess or improve public sector performance.

Draw three boxes on your plan: inputs, outputs, outcomes.
Fill each with facts from the scenario.
Label the arrow between inputs and the price paid as economy, inputs to outputs as efficiency, and outputs to outcomes as effectiveness.
Write one point and one scenario fact for each E.
Add one measurement difficulty and one recommendation, then write your answer.

Common mistakes in Value for Money and Performance Measurement

Treating economy as simply spending less.
Students link economy to cost cutting and forget quality.
Fix: Define economy as lowest cost for a given quality. Warn about false economy when quality drops.
Confusing efficiency with effectiveness.
Both sound like 'doing well', and the words are used loosely.
Fix: Efficiency is outputs per input. Effectiveness is whether outputs achieve the goal. Efficient but pointless is possible.
Using profit-based measures only.
Students carry over commercial ratios from private sector questions.
Fix: Use cost per unit, service levels, waiting times and outcome measures. Say why profit is not the aim.
Listing the 3Es as a definition with no application.
Learned theory is easy to write out without using the case.
Fix: Use a scenario fact in every point. SBL marks go to application and professional skills, not recall.
Ignoring measurement difficulties and stakeholder conflicts.
Students focus on what to measure and not on why it is hard.
Fix: Add points on outcome time lags, outside factors, conflicting objectives and the risk of targets being gamed.
Giving no judgement or recommendation.
Students run out of time after the theory.
Fix: Finish with a short conclusion on overall value for money and one or two practical actions.

Worked examples

Example 1

A regional ambulance service spent $12 million last year and responded to 40,000 emergency calls. This year it spent $13.2 million and responded to 48,000 calls. Average response time was unchanged. Assess the change in efficiency.

Show the solution

Efficiency links inputs to outputs, so calculate cost per call.
Last year: $12,000,000 ÷ 40,000 = $300 per call.
This year: $13,200,000 ÷ 48,000 = $275 per call.
Cost per call fell by $25, which is 25 ÷ 300 = 8.3% (to one decimal place).
Spending rose 10% (1.2 ÷ 12) while calls rose 20% (8,000 ÷ 40,000), so output grew faster than input.
Effectiveness cannot be fully judged from this. Response time is unchanged, but outcomes such as survival rates are not given.

Answer: Efficiency improved: cost per call fell from $300 to $275 (about 8.3%). Effectiveness is unproven because the data gives no outcome measures. The service should also report patient outcomes.

Example 2

A city council cut the cost of its road repair contracts by choosing the cheapest bidder. Within a year, repairs failed and the council had to repeat the work. Residents complain. Explain the value for money issues.

Show the solution

Economy: inputs were bought at the lowest price, so on the face of it economy improved.
But quality was not held constant. The cheap contractor's work failed, so this is false economy.
Efficiency: repeat work means more inputs for the same output. Cost per successfully repaired road rose.
Effectiveness: the aim is safe, durable roads. Failed repairs and complaints show the objective was not achieved.
Stakeholders: residents bear the disruption, and taxpayers pay twice. Public trust falls.
Measurement: a measure based only on contract cost would miss this. Use whole-life cost, repair durability and resident satisfaction.
Recommendation: set quality standards in tenders, use performance clauses and monitor outcomes.

Answer: The council gained economy but lost efficiency and effectiveness, so value for money fell. It should judge bids on whole-life cost and quality, and track durability and satisfaction as well as price.

Exam tips

Always tie each E to a fact or figure in the case. Generic definitions earn few marks.
If figures are given, calculate a ratio such as cost per unit, then comment on what it means.
Show that the Es can conflict, and give one example. This shows commercial acumen.
Cover why outcomes are hard to measure when the requirement mentions performance or KPIs.
Close with a clear judgement and a recommendation. This supports your professional skills marks.

Value for Money and Performance Measurement: frequently asked questions

What is the difference between economy, efficiency and effectiveness?

Economy is the cost of inputs for a given quality. Efficiency is the output you get from those inputs. Effectiveness is whether the outputs achieve the intended outcomes. You need all three to judge value for money.

Why is performance harder to measure in the public sector?

There is no profit figure, and objectives are many and often conflict. Outcomes are hard to quantify and take time to appear. Outside factors also affect results, and stakeholders value outcomes differently.

Is there a fourth E in value for money?

Some frameworks add equity, meaning fair access and treatment. Use it if the scenario raises fairness or access issues. The core test is still economy, efficiency and effectiveness.

How do I answer a value for money question in SBL?

Split the facts into inputs, outputs and outcomes. Apply each E using case facts, note trade-offs and measurement problems, then give a judgement and recommendation. Keep the answer tied to the scenario.
