Requirements Traceability Gap Findertrace sheet
For whoever owns the trace before the assessor samples it

Paste your requirements export. See the breaks in the trace.

Requirements Traceability Gap Finder reads your requirements export and test results line by line. Paste your requirements export and test results: IDs, parent links, verification method, linked tests, results and dates, with or without the requirement text. Every requirement comes back traced up to its parent and across to its verification, with the breaks an assessor samples: no parent, no verification, a test that failed or never ran, a requirement changed after its last passing test, and tests that trace to nothing, each cited to the clause of ISO 26262, IEC 62304, ISO 13485, DO-178C, AS9100D or IATF 16949 that asks for it.

Trace your own exportA first-pass traceability integrity review of your export; it never claims the matrix is complete. 25 requirements free, no account.
  1. Paste IDs and links only if you prefer; the requirement text is optional and nothing leaves your browser until you save.
  2. A paste, never a connection: an export from your requirements tool or your spreadsheet matrix. Nothing connects to DOORS, Jama, Polarion or anything else.
  3. Every break shows the clause that asks for the link and the column it read.
  4. It rules on nothing. It never calls a product or a project fit for assessment: every break is a question for the requirement owner or the reviewer.

40 requirements, 7 with no passing verification, 1 changed since it was tested.

8 of 10 findings raised on 15 requirements, 2 tests tracing to nothing, every one cited to IEC 62304, ISO 13485 or the FDA QMSR.

Walk into the confirmation review or the design file review already knowing each link the assessor will pull on, and the clause behind it. It works from the export you already have, in your browser, with no connection to your tools.
01

Paste the export as it comes

One requirement per row: ID | Parent at least, or a header row with level, verification method, verified by, status, safety rating, last changed, derived and validation. The column names requirements tools and spreadsheet matrices export are read as they are. Test results go in the second box.

02

Read the trace, need to proof

Each chain is drawn from the top-level requirement down, with the verification on the right: highlighted where it is traced and passed, ringed where it breaks, struck through where the requirement changed after its pass. Safety-rated requirements come first.

03

Take the questions to the review

Ten findings in a fixed order, each naming its requirements and the clause of the standard you ticked. The review sheet has blank columns for the reviewer's decision; the board summary puts the counts on one page.

Box 1, one requirement per row: ID | Parent, or a header row with any of Level, Verification Method, Verified By, Status, ASIL or DAL or Safety Class, Last Modified, Derived, Validation, Text. Box 2, optional, one test per row: Test ID | Result | Date, with Requirements if the export carries it. Tabs, pipes, commas or double spaces. First lines such as standards: ISO 26262, ASPICE or as at: 2026-10-01 set the options below.

Your requirements traceability matrix, read the way an assessor samples it

A requirements traceability matrix is the table that ties each requirement to the one above it and to the test, analysis or inspection that proves it. An assessor rarely reads it end to end; they pull a thread: pick a requirement, follow it up to the need it serves and across to its passing result, and ask about any requirement changed since. This reads your matrix, or the export your requirements tool produces, and pulls every thread at once, in your browser.

The rules are published in full: what each standard asks of the trace, the ten findings, the requirement levels it reads, the verification methods, what a requirements traceability matrix is, suspect links and the requirements traceability matrix template. It reads the paste only; a finding names the clause and asks the question, never a ruling on the product.

Breaks in the requirements trace: the questions buyers ask

What does Requirements Traceability Gap Finder do?

It reads your requirements export and test results line by line and traces every requirement up to its parent and across to its verification. It comes back with the breaks an assessor samples, each cited to the clause of the standard that asks for the link.

What breaks does it find?

No parent, no verification, a test that failed or never ran, a requirement changed after its last passing test, and tests that trace to nothing. Each break names its requirements and the clause behind it.

Which standards does it cite?

ISO 26262, IEC 62304, ISO 13485, the FDA QMSR, DO-178C, AS9100D, IATF 16949 and ASPICE, read clause by clause from the published text. DO-254, IEC 61508, ARP4754B and ISO/IEC/IEEE 29148 are named, not quoted.

Does it connect to my requirements tool?

No. It is a paste, never a connection: an export from your requirements tool or your spreadsheet matrix. Nothing connects to DOORS, Jama, Polarion or anything else.

What do I paste?

One requirement per row as ID | Parent at least, or a header row with any of level, verification method, verified by, status, safety rating, last changed, derived and validation. Test results go in the second, optional box as test ID, result and date.

Do I have to include the requirement text?

No. You can paste IDs and links only, and the requirement text is optional, so nothing leaves your browser until you choose to save.

Does it tell me my traceability matrix is complete?

No. It is a first-pass traceability integrity review of your export, and it never claims the matrix is complete.

Does it rule on my product or project?

No. It never calls a product or a project fit for assessment; every break is a question for the requirement owner or the reviewer.

How does it present the trace?

Each chain is drawn from the top-level requirement down with the verification on the right: highlighted where it is traced and passed, ringed where it breaks, and struck through where the requirement changed after its pass. Safety-rated requirements come first.

What does the review sheet give me?

Ten findings in a fixed order, each naming its requirements and the clause of the standard you ticked. The review sheet has blank columns for the reviewer's decision, and the board summary puts the counts on one page.

How does it treat a requirement changed after it passed?

A requirement changed after its last passing test is one of the breaks. It is drawn struck through where the requirement changed after its pass.

How much does it cost to try, and does my data leave my browser?

25 requirements are free and no account is needed. Nothing leaves your browser until you save.

How Requirements Traceability Gap Finder compares with the alternatives

A spreadsheet is better as the traceability matrix you keep and hand over, because it is free and the assessor can read it directly. Requirements tools such as DOORS, Jama and Polarion are better at holding the requirements themselves and keeping live links as they change, and a consultant or assessor is better for judging whether a break matters and what a safety case needs. A general AI assistant is better at explaining what a suspect link is or drafting the review note, but it does not trace your export up to parent and across to verification against the clause text of ISO 26262, IEC 62304, ISO 13485, the FDA QMSR, DO-178C, AS9100D and IATF 16949. The finder reads the export you already have and names the breaks an assessor samples, each cited to its clause; it is a first-pass review, never claims the matrix is complete, and rules on nothing.
