Benchmarking: formula sheet

Key formulas

Performance gap

Gap = Benchmark performance − Own performance

For cost measures where lower is better, compute Own cost − Benchmark cost. State clearly which direction is favourable.

Gap as a percentage of benchmark

Gap % = (Own − Benchmark) ÷ Benchmark × 100

Useful to compare gaps across different measures. Always divide by the benchmark, not by your own figure.

Core idea of benchmarking

Measure → Compare with the best → Find the reasons for the gap → Adopt or adapt → Monitor → Repeat

A cycle, not a single event. Use it to structure descriptive answers.

Performance gap

Gap = Benchmark value − Own value (for measures where higher is better); Gap = Own value − Benchmark value (where lower is better)

Use this to show the improvement needed. State the direction clearly.

Gap as a percentage

Gap % = (Gap ÷ Benchmark value) × 100

Useful in numerical comparisons of cost, time or defects.

Classification rule

Who compared with → internal / competitive / functional / generic; What compared → strategic / process / performance

Use this to classify any scenario in the objective section.

Performance gap

Gap = Benchmark performance − Own performance

For measures where lower is better (cost, time, defects), use Own − Benchmark so a positive gap means you are worse. State your sign convention.

Gap as a percentage of benchmark

Gap % = (Own − Benchmark) ÷ Benchmark × 100

Use for cost, time or defect measures. Divide by the benchmark, not by your own figure.

Camp's stages (one common grouping)

Planning → Analysis → Integration → Action → Maturity

Sources vary in how they number and label the steps. Match the stages the question or your answer states.

Potential saving from closing the gap

Saving = Gap per unit × Volume

Use only if the gap is fully closed. Show any assumption about partial closure.

Performance gap

Gap = Benchmark performance − Own performance

Use the same measure and same basis for both. For cost or time measures, a positive gap means you are higher (worse) than the benchmark when you compute Own − Benchmark. State which direction you use.

Code of conduct principles

Legality · Confidentiality · Reciprocity · Purpose-limited use · Consent · Honesty · Preparation

Recall these as a checklist. In an exam, name each principle and link it to the facts in the case.

Critical success factors

Commitment · Clear scope · Right partner · Trained team · Own process understood · Reliable data · Action and follow-up

Not a fixed official list. Use it as a framework and tie each point to the case.

Performance gap

Gap = Actual figure − Benchmark figure

For cost measures a positive gap is unfavourable. For quality or output measures, reverse the sign of the interpretation.

Percentage gap

Gap % = (Actual − Benchmark) ÷ Benchmark × 100

Use the benchmark as the base, not your own figure.

Potential saving

Potential saving = (Actual unit cost − Benchmark unit cost) × Actual volume

This is the maximum saving if the gap is fully closed. Adjust for gaps that are not controllable.

Cost per unit of activity

Cost per activity unit = Activity cost ÷ Number of activity units

Used to compare processes such as cost per purchase order or per invoice.

Quick revision

• Benchmarking compares your performance with the best practice to find gaps and improve.
• It is continuous, not a one-time exercise.
• The aim is to learn why the best performs better, not only to copy numbers.
• Internal benchmarking compares units or departments within the same organisation.
• Competitive benchmarking compares with direct competitors, but data is harder to obtain.
• Functional benchmarking compares a function with the best in any industry.
• Match the type to the scenario: same firm means internal, rival means competitive, other industry means functional or generic.
• Follow the process in order: plan, collect data, analyse the gap, set goals, implement, and review.
• The gap is the difference between your measure and the benchmark, and it must be explained.
• Follow the code of conduct: legality, confidentiality, and no misuse of shared information.
• Top management support and clear measures are key success factors.
• End practical answers with a specific recommendation.

Common mistakes

• Describing benchmarking as a simple comparison of this year's results with last year's. Fix: Say the comparison is with the best performers, internal or external, and that the aim is to learn their practices.
• Writing only about numbers and ignoring processes. Fix: Add that the key step is finding out why the leader performs better and how, then adapting that process.
• Treating functional and generic benchmarking as the same. Fix: Functional stays within the same or related industry. Generic crosses into unrelated industries because the process is similar.
• Calling every comparison with a rival competitive and ignoring the subject. Fix: Also say what is compared. Rival cost per unit is competitive and performance benchmarking.
• Listing steps without explaining them or linking to the case. Fix: Give one line of meaning for each step and use the business named in the question.
• Treating benchmarking as a one-time exercise. Fix: Always add monitoring and recalibration. The benchmark moves, so the cycle repeats.
• Listing the code of conduct points without linking them to the case. Fix: After each principle, add a clause such as 'here the firm shared the partner's data with a rival, breaching confidentiality'.
• Assuming the partner must be a competitor in the same industry. Fix: Choose partners by the process studied. Non-competitors in other industries can be excellent and are often more willing to share.
• Comparing totals instead of per-unit figures. Fix: Convert everything to per unit or per activity before computing any gap.
• Using actual cost as the base for percentage gap. Fix: Divide by the benchmark figure and state the base in your answer.

Exam tips

• For definition questions, include three keywords: continuous, systematic, and best practice. These carry the marks.
• In case-based questions, name the benchmark source (internal, competitor or other industry) from the case and link your points to it.
• When asked for limitations, include data comparability, cost and time, resistance to change, and the risk of blind copying.
• In MCQs, watch for options that call benchmarking a one-time exercise or a pure financial-variance tool. Both are wrong.
• For numerical gaps, state favourable or adverse and divide by the benchmark figure.
• Expect 2-mark MCQs that give a short scenario and ask you to pick the type. Check partner first, then subject.
• In descriptive answers, define each type in one line and add an example from an Indian company setting.
• If a question asks for differences, use a clear contrast on partner, data availability and ideas gained.
