A Blank Cell in Your Trace Matrix Is a Finding Waiting to Happen

A trace matrix looks complete because every column has a header. The gaps hide in the cells. Three failures show up over and over.

A trace matrix looks complete because every column has a header. The gaps hide in the cells.

Three failures show up over and over.

An input with no output.

The Product Requirement has a verification record but the Design Output cell is empty.

You verified a specification that does not formally exist. The protocol was written against a moving target.

A risk control that never became an input.

It sits in the Hazard Analysis or the FMEA (Failure Mode and Effects Analysis) but never earned a Product Requirement ID.

It is a good intention with no home in the design.

A reference that points to the wrong document.

The cell cites ISO 13485 or 21 CFR Part 820 instead of the test-method standard that actually supplies the requirement.

The high-level QMS (Quality Management System) standard does not belong in the reference cell.

Each of these is invisible in a summary and obvious in a row-by-row read.

Which is exactly how an auditor reads it.

Fill the output. Give the control an ID. Cite the standard that supplies the method.

The matrix only protects you if every cell carries a real, traceable answer.

rmForge enforces the chain on every Hazard Analysis row, so controls arrive as traceable requirements instead of orphan notes.
