A troubleshooting report records what failed, which tests were performed, what those tests showed, and what should happen next. It lets another person continue an investigation without repeating every conversation or treating an untested explanation as the root cause.
Use the template below for software support, QA investigations, or an engineering handoff. It differs from a bug report template: the bug report describes a failure; the troubleshooting report also preserves the investigation and verification record. You can write one even when the cause is still unknown.
Copyable troubleshooting report template
Keep observations, hypotheses, and decisions in separate fields. Record “not tested” or “unknown” when appropriate. Do not collect private account information simply because the template has room for it.
Investigation title: Original ticket / issue reference: Report owner / receiving team: Investigation date and time zone: Customer task and observed failure: Expected result: Customer impact / available workaround: Known scope / unknown scope: Environment and starting state: Application / release: Browser / OS / device: Relevant account role or settings: Reproduction steps and frequency: Evidence reference / useful timestamp: Access audience / sanitization check: Test 1: Question or hypothesis: Starting conditions: One change made: Observed result: What the result supports / does not establish: Tests not yet performed and why: Confirmed findings: Unconfirmed possible causes: Next action / owner / agreed update: Verification task / expected outcome: Verification environment and result: Remaining limitations: Closure or follow-up decision:
How an investigation becomes a useful report

Start with the customer’s task. “Export fails after I select CSV” gives the next investigator a reproducible question. “The app is broken” does not. Record the starting state, selected options, and the exact visible error before proposing changes.
Write each test as a question and an observation. If a new browser profile works, that narrows the investigation to differences between profiles; it does not prove that a particular extension caused the failure. State what remains untested. Use the technical troubleshooting checklist when choosing the next test.
A filled troubleshooting report example
The following case is fictional. It shows the structure of an investigation, not a claim about a real product, customer, or fix.
| Field | Completed example |
|---|---|
| Task and symptom | A support user opens a saved report, selects CSV, and sees “Export unavailable.” The page remains responsive. |
| Expected result | The selected report downloads as a CSV file. |
| Impact and scope | One reported user cannot complete the CSV export. PDF export works in the reported session. Other accounts have not been tested. |
| Environment | Fictional app release 4.2, a desktop browser, support role, and the same saved report. Exact browser version belongs in the real report. |
| Initial reproduction | Open the saved report, select CSV, and start export. The same visible error appears in two attempts. |
| Evidence | Recording at 00:18 shows the selected format; 00:24 shows the error. Use approved internal links in a real report. |
| Confirmed finding | The tested failure is specific to the CSV path in the reported session. A cause has not been established. |
| Next action | The application team checks the CSV export path. Support retains responsibility for customer updates until a handoff is accepted. |
The test log matters as much as the summary
| Question | Test and observation | Safe interpretation |
|---|---|---|
| Does another format fail? | Keep the report and session unchanged; select PDF. A PDF downloads. | The general ability to start an export worked in this test; CSV remains the failing path. |
| Does a fresh profile change the result? | Use the same role, report, and CSV option in a clean profile. The same error appears. | The tested profile change did not remove the symptom. It does not rule out all client-side causes. |
| Do other roles fail? | Not tested because an approved comparison account is unavailable. | Account-role scope remains unknown; do not call this an all-user failure. |
A report that says “we tried everything” loses the details needed to evaluate the work. A short table showing three controlled questions is more useful than a long list of unrelated fixes.
Use evidence to answer a specific question
A screenshot can show an error or static layout. A screen recording is useful when the order of actions matters. Link the relevant timestamp and explain what the viewer should notice. Keep the written steps so a recipient does not have to watch a full recording to understand the issue.
Technical logs or request identifiers can help with an application investigation, but include them only when available through the approved capture method. A recording link does not imply that console or network evidence was collected. Check who can open the evidence, remove unrelated private details, and preserve the original record under your team’s access rules.
Hand off the investigation without losing ownership
Choose the receiving team based on the open question. A request to engineering should say what support already checked and what needs engineering access. A request to a team lead might instead concern an approval decision. The support ticket escalation process explains how to obtain an accepted handoff.
Handoff summary: Customer task and impact: [...] Reproduction / evidence: [...] Tests already performed: [...] Confirmed findings: [...] Open question requiring your team: [...] Requested next action: [...] Customer-update owner: [...] Acceptance / next-update agreement: [...]
If a software defect is confirmed, reference the investigation in the Jira bug report. Avoid copying conflicting versions of the same test log across systems. Keep one authoritative investigation record and link to it.
Verify the original task before closing
Verification should repeat the customer’s starting state and failing sequence, with the relevant permissions and environment. Record what changed, the expected result, and what actually happened. If only a workaround was tested, say so. A successful test with an administrator account does not establish success for the customer’s role.
For the fictional CSV case, the acceptance check is not “the patch deployed.” It is “the support-role user can export the same saved report as CSV and the resulting file opens with the expected data.” Check other formats only when the change could affect them. Name the owner of any remaining follow-up.
Frequently asked questions
Can I write a troubleshooting report without knowing the cause?
Yes. Describe the failure, controlled tests, confirmed observations, and unanswered questions. An honest report with an unknown cause is useful; an unsupported root-cause statement can send the next person in the wrong direction.
How detailed should the report be?
Include enough context for someone to repeat the relevant tests and understand the next decision. Keep lengthy logs in approved evidence storage and link the necessary portions. Remove tests that concern unrelated problems.
Who should own the report?
The investigation needs a named owner. The customer update may remain with support even after engineering accepts the technical work. Record both responsibilities when they differ.
