Tender Case Study: What Evaluators Need to See

What Should You Include in a Case Study for a Tender?

In bid writing, a case study for a tender should be proof that you’ve delivered work like the buyer needs, not a glossy account of how good you are. It gives evaluators facts they can match to their criteria: relevant scope, a credible method, controlled risks and measurable results.

The strongest example uses six short parts: contract overview, challenge, delivery approach, outcomes, added value and client validation. You’ll see what belongs in each section, how to use evidence that earns confidence, and how to keep useful proof ready before the next deadline lands.

Why This Matters in Tender Evaluation

A case study has one job: make it easy for a buyer to see that you can deliver this contract safely and well.

In public sector tenders, evaluators assess responses against evaluated criteria and scoring guidance. Read the tender documents to understand the evidence requirements. The Government’s assessment and award guidance is a useful reminder that good intentions do not earn marks. Clear evidence does.

Buyer concerns and priorities may also have been signalled through market engagement before the formal submission stage of the procurement process.

Your service may be excellent, but if relevance is buried in general claims, the evaluator cannot do much with it. Where applicable, map proof to social value, sustainable procurement or innovation procurement requirements. A well-chosen example should support your wider win strategy and reduce perceived risk. It shows that you have handled a similar client, scale, pressure or delivery issue before.

If an evaluator has to infer relevance or hunt for the result, the evidence is working too hard.

Teams often write tender answers around a full day of delivery. That is why familiar projects get copied in at the last minute. A little structure avoids that scramble and makes it easier to understand how buyers score tender responses.

How to Structure a Case Study That Scores in a Tender?

Most SMEs already have the raw material. It sits in mobilisation plans, KPI reports, client emails, contract reviews and the experience of those who delivered it.

The job is to turn it into scoreable proof, not just capability claims.

Start With the Contract Snapshot

Give the evaluator enough context to judge similarity. Include the client name, or an authorised anonymised description, sector, contract value, contract duration, delivery dates, locations, core scope and team size.

This snapshot should work for a commercial contract as well as a public procurement example. Then connect it to the tender requirement in one plain sentence. If the buyer needs a multi-site service with a short mobilisation period, say whether your example involved those conditions.

If market engagement identified a buyer concern before the tender was issued, reflect it in your evidence. If every detail is hidden behind “confidential”, relevance becomes hard to assess. Get client permission for names, values and quotes before you use them.

Explain the Challenge and Delivery Approach

Set out the starting point. That may be an urgent mobilisation, complex stakeholder group, service continuity risk, legacy data issue, safeguarding requirement or high-volume demand.

Then explain what your team did. Include roles, governance, reporting, quality controls, escalation routes and how you monitored performance. A delivery approach should show decisions and controls, not a list of policy titles.

Keep it relevant to the question. A brilliant project story is still the wrong evidence if it does not address the buyer’s stated concern.

Use a Six-Part Case Study Format

Six labelled sections stop a capable project becoming a vague 800-word story.

Section	What to Include	What It Proves
Contract overview	Client, sector, dates, contract value or scale, scope	Comparable experience
Requirement and challenge	Starting position, risks and constraints	Understanding of the work
Delivery approach	Actions, people, controls and reporting	A credible method
Measurable outcomes	KPIs, targets, actual results and timescales	Performance evidence
Added value and social value	Social value, improvements or innovation	More than baseline delivery
Client validation	Reference, quote or permission to contact	Claims can be checked

Use the six-part structure to score maximum marks within the word limit. When space is tight, shorten sentences rather than removing evidence.

If the tender asks for two examples, provide two focused examples. Don’t stretch one project across every question until it starts to look like it was the only contract you have ever delivered.

Turn Delivery Into Measurable Outcomes

Good results make the difference between “we can do this” and “we have done this”.

Use Traceable Results, Not Broad Claims

“High-quality service” and “excellent customer care” are capability claims. They are not evidence on their own.

Use the measures the client tracked: service-level performance, response times, completion rates, audit scores, satisfaction results, cost savings, incident reduction or retention. Pair KPIs, targets and actual results with quantitative evidence, including the timeframe and data source.

Where possible, show the starting point, target and achieved result. If there was no baseline, don’t invent one. State the actual result and how it was verified.

The reports, dashboards and contract review notes form the evidential backbone of the case study. Keep them available behind the case study for clarification, reference checks or future bids. More ideas sit in these bid case study proof points.

Add Social Value and Client Validation

Social value only earns marks when it answers the buyer’s requirement. If it is scored, use the Government’s Social Value Model guide to check the theme, outcome and measurement requested.

State what you delivered, who benefited, how many people were reached and how the result was tracked. Measure environmental or responsible-procurement evidence against relevant sustainable procurement indicators, rather than relying on general promises about local impact.

Finish with a client reference where the tender permits it. Where innovation, testing or new delivery methods genuinely formed part of the contract, explain the added value in a way relevant to innovation procurement, then include a named contact, role and permission to approach them. A short client quote can add colour, but it should support the evidence, not replace it.

Pre-Submission Case Study Checklist

Before you submit, ask whether the case study gives an evaluator a clean route to the marks.

• It matches the contract scope, sector, scale or risk in the question.
• It includes contract duration, delivery dates, locations and contract value or a meaningful scale measure.
• It separates what your team did from the results achieved.
• It uses real figures, timeframes and evidence sources.
• It addresses social value, quality or innovation only where the buyer asks for it.
• It has client approval for names, quotes and contact details, plus a client reference where the tender permits one.
• It follows the word count, format and every sub-question.

Keep a Working Case Study Library

Build a case study library, not a folder full of old PDFs. Keep a short evidence sheet for each project with the contract facts, results, source documents, client permissions and approved wording. Assign a named internal owner for evidence maintenance across bid writing and proposal management.

A case study library should have an owner and a review date. Tag entries by sector, service, geography, contract scale, challenge and outcome, plus sustainable procurement or innovation procurement where relevant. Review them after contract reviews and at least annually. A three-year-old result may still be useful, but only if it remains accurate.

Before each tender submission, run the case study through a pre-submission bid checklist. It’s faster than explaining a missing figure at 4pm on deadline day.

Common Mistakes That Lose Marks

A generic company profile is not a case study. It makes capability claims, telling the buyer what you want them to think rather than showing what you can prove.

• Reusing the same broad example without showing why it fits the current requirement.
• Listing activities without linking them to a result, KPI or managed risk.
• Hiding key facts, then expecting the evaluator to assume the work was comparable.
• Bolting on generic sustainability wording merely to claim sustainable procurement, without supporting evidence.

Do not pretend every project was perfect either. If something went wrong, a brief explanation of the control, correction and lesson can show maturity, including in projects involving innovation procurement. Unsupported innovation language won’t replace that evidence. Buyers are assessing delivery risk, and they know real contracts have bumps in the road.

Final Thoughts

A strong case study for a tender is clear, relevant and backed by evidence someone can check. It gives the evaluator confidence that your delivery claims are more than well-written promises, supporting tender success.

Your team already holds much of the proof. Match the example to the requirement, quantify results and retain the evidence. Then pull it into a format that’s easier to read, easier to score and harder to dismiss.

FAQ

How Long Should a Case Study for a Tender Be?

Follow the tender instructions first. There is no standard length. A short answer still needs the same proof, but each section may be one or two tightly written sentences.

How Many Examples Should We Include?

Include the number requested. If the buyer does not specify, choose the few examples that best match the scope, risk and scoring criteria rather than adding every project you can remember.

Can We Anonymise a Client?

Yes, where confidentiality requires it. Give enough approved detail to show sector, scale, scope and outcomes. Ask the client what may be shared before submission.

What Makes a Client Quote Useful?

A client reference is useful when a client quote confirms a result, service quality or relationship point already shown in the evidence. It should be attributed, approved and short enough to earn its place.
