Structure a technical due diligence report around decisions, evidence and uncertainty. Follow an illustrative finding from observation to remediation and ownership.
A technical due diligence report should help a reader decide what to do next. A long inventory of frameworks and repository statistics rarely achieves that on its own. Organise the report around the transaction questions, material findings and confidence in the evidence. The example below is illustrative; it does not describe an Orsun Tech client or a measured result.
Start with a decision summary
State the reviewed product, date, access and intended decision. Summarise material risks and the conditions under which the technical plan appears achievable. Separate facts from management statements and reviewer judgement. Include unresolved questions in the executive summary when they could change the decision; do not hide them in an appendix simply because the evidence was unavailable.
| Finding field | Illustrative entry | Why it matters |
|---|---|---|
| Observation | A restore procedure exists, but no completed rehearsal was provided | Distinguishes documentation from demonstrated recovery |
| Evidence | Procedure version, interview notes and available backup records | Makes the claim inspectable |
| Impact | Recovery duration and completeness remain unverified | Connects the gap to business continuity |
| Action | Restore an agreed sample into an isolated environment | Defines a concrete way to reduce uncertainty |
| Acceptance | Record recovered data, elapsed time and unresolved dependencies | Prevents closing the finding after documentation alone |
Show coverage and confidence
For each area, explain what was inspected, sampled or excluded. A read-only code inspection supports different conclusions from an authorised runtime test. If operating records cover only a short period, state that limitation. Use confidence labels with definitions so that “high” means consistent evidence rather than the reviewer’s tone. A serious but unverified risk should remain visibly different from a reproduced defect.
Make recommendations usable after the deal
Group actions by dependency and decision horizon. Some questions must be resolved before commitment; others belong in integration planning or ordinary maintenance. Name an accountable role and describe the evidence required for closure. Where effort is estimated, record assumptions about system boundaries, staffing and access. A precise-looking number without these assumptions will be hard to use when the receiving team starts work.
- Confirm factual findings with the relevant technical owners.
- Preserve disagreements and missing evidence rather than silently averaging opinions.
- Review the executive summary against the original transaction questions.
- Deliver a findings register that can be updated without rewriting the full report.
Keep sensitive evidence in controlled appendices or references. The broad distribution report should contain enough information to assess the conclusion without exposing credentials, customer records or unnecessary implementation details.

Frequently asked questions
Should the report give a single technical score?
A score may summarise an agreed rubric, but it should not replace findings, evidence and uncertainty. Readers need to know which risks affect their decision.
How detailed should the executive summary be?
Enough to explain the material risks, decision implications and unresolved questions. Technical reproduction details can remain in the findings register or controlled appendix.
Can we include unverified concerns?
Yes, label them clearly and state the evidence needed to confirm or dismiss them. Do not present an access limitation as a passed check.
Who should review factual accuracy?
The relevant product and technical owners should review facts. Preserve reviewer judgement and document material disagreement rather than allowing important findings to disappear.
What makes a finding ready for handover?
It has an owner, evidence, impact, proposed action, dependencies and an observable closure criterion.
Bring the scope. We will help make it buildable.
Share the user journey, integrations and launch constraints. We can clarify the scope and prepare an estimate with assumptions and exclusions.
