Practical guide
How to connect a business case to value evidence throughout delivery
Build a traceable connection from each material approved expectation to the benefit record, responsible people, period evidence and decisions that follow.
Wovex
Summary
Connect a business case to value evidence by giving each material benefit claim a stable reference and following it into a defined benefit, owner, measure, starting position and dated expectation. Link later observations and review decisions back to that chain, keeping approved expectations distinguishable from current forecasts. Check the connection when scope, assumptions or ownership change, and agree who maintains it after project closure. A document link alone does not establish that the evidence supports the claim.
Start with the approved claim you need to follow
A business case may explain why an investment should proceed while the later evidence sits in operational reports, benefit records and meeting decisions. The practical task is to connect those records so a reviewer can follow one material claim without reconstructing the investment story.
Begin with a specific approved expectation. Identify its location and version in the business case, what improvement it describes, who should benefit and when it is expected. Use a stable reference that people can recognise across the supporting records.
This does not require every system to store another copy of the business case. It requires an understandable relationship between the approved position and the information used to review it. The Teal Book places benefits management across the life cycle, providing context for that continuing connection.
Use a business case to evidence checklist
Apply the checklist to each material benefit, with effort proportionate to the decision it supports.
Connection | Check that a reviewer can establish |
|---|---|
Approved claim | Which statement, source version and decision authorised the expectation. |
Benefit and recipient | The defined improvement and the people or operation expected to experience it. |
Responsibility | Who maintains the benefit, supplies observations and responds to a material issue. |
Measure and baseline | What is measured, its unit, source, starting period and relevant limitations. |
Target and forecast | The dated commitment and current expectation, kept distinguishable. |
Period evidence | The observation, population, source and explanation for the reporting period. |
Review decision | What was concluded, the evidence available and the reason for the response. |
Operational handover | Who will maintain the chain when delivery responsibility changes or the project closes. |
A link is useful only when the destination answers the question. Check that the referenced report uses the same benefit definition and population. A working hyperlink to an unrelated or superseded report creates apparent traceability without a usable explanation.
Test the connection with a worked record trace
Consider a fictional data-improvement project whose business case expects fewer duplicate customer records. The following references are illustrative labels, not Wovex record IDs or a required naming scheme.
Claim C-07 identifies the expectation in section 3.2 of the approved business case and its approval record.
Benefit B-04 describes the reduction in duplicate records, the affected service and the operational person responsible for the improvement.
Measure M-12 defines the duplicate-record proportion, its baseline observation and the dated target and forecast used for review.
Extract E-03 supplies a completed-period result but identifies a legacy dataset excluded from that observation.
Decision D-02 limits the current claim to the covered population, assigns investigation of the gap and sets the next evidence review.
The chain lets a sponsor move from the original expectation to the actual conclusion. It also exposes a limitation: the current observation does not yet establish improvement across the whole population envisaged by the business case.
This is more useful than a green completion status or a folder containing all five records without explaining their relationships. It does not establish causality or prove that every source is correct.
Keep changes connected without rewriting the approved position
When an assumption, scope or timing changes, identify the affected claim and measure before updating the current expectation. Record the reason, relevant dates, decision authority and the evidence considered.
A forecast revision and a target revision are different decisions. Keep the approved commitment recognisable and explain which periods the new forecast affects. A later reviewer should be able to distinguish a more realistic expectation from a newly agreed objective.
Review the record references when ownership changes, evidence is corrected or a report is replaced. Agree which source remains authoritative and how readers will recognise a superseded record. The aim is reliable interpretation, not a claim that every system automatically synchronises its values.
For the comparison definitions, use the baselines, targets and forecasts guide. This checklist applies those definitions to the connections between records.
Carry the chain into operational use
Before project closure, confirm who will provide results, maintain explanations and bring material changes to the appropriate review. Make the continuing responsibility explicit rather than assuming the former project team will keep it working.
Include access to the approved claim and decision context in the handover. An operational owner needs to understand why a target exists and what assumptions underpin it, as well as which report to complete.
Use the post-closure benefits tracking guide for the handover and recurring review arrangements. The business case remains the source of the approved rationale; continuing evidence shows how that rationale is developing in practice.
Use a Value Case where it helps organise the connections
Wovex’s Value Case can bring relevant value-model items, supporting artefacts and recorded activity into a structured review context. Assess that arrangement against one complete claim-to-evidence chain and confirm the plan, access and configuration required.
A record of a decision can preserve its explanation, but does not establish an enforced approval gate. Do not assume automatic forecast snapshots, immutable history or copying between target fields and reporting values.
This article provides a generic record-tracing method, not a tested product demonstration. Keep the original business case, current evidence and human decisions understandable whichever tools are used.
Sources and context
The checklist, record references and duplicate-record scenario are Wovex guidance; the example is fictional. Sources supply lifecycle context, not an official evidence-linking standard or product endorsement. Confirm the actual source records, governance and supported product scope.
