Why use a bidirectional traceability matrix?
Bidirectional traceability matrices help ensure that all the required software requirements (only what is required is developed) are addressed in software design and tested in the software testing activities. Bidirectional traceability matrices also make it less likely that requirements are misinterpreted as they are refined.
What is bi-directional traceability?
Bi-directional traceability with the hazard analyses that include software allows a project to develop and maintain a list of all software safety-critical components that have been identified by the system hazard analysis. The bi-directional traceability with the hazard analyses allows the engineers and safety personnel to see which software components are software safety-critical components and allows the project to ensure that the software safety-critical requirements are implied to those software components that trace to hazard analyses.
Why is it important to trace test cases?
To ensure full traceability between requirements and tests, it is important to trace test cases, test scripts, test data, and other supporting test information not already found in the test procedures to the relevant test procedures. This level of trace information may or may not appear in a traceability matrix.
How do traceability matrices help?
Traceability matrices help ensure that test procedures verify one or more software requirements by mapping those procedures back to one or more software requirements.
Why is traceability important?
Traceability is important because it can point out software requirements that are not tested (i.e., missing tests) and tests that do not serve to test requirements (i.e., extra tests). Keep in mind that a single requirement could trace to multiple test procedures. The reverse is also true.
How to show traceability in Westfall?
Using a matrix such as the one shown below (Bidirectional Requirements Traceability, Westfall, 2006 356) allows a single exercise to show traceability both forwards and backward. The matrix is completed left to right early in the appropriate phase in the project life cycle. As each column is completed, the forward trace is extended to the next set of products. Simply starting with a column such as the LLD (low-level design) Section and looking at the data in the columns to the left shows the backward traceability from an LLD element to its parent HLD (high-level design) element and back to the parent requirements.

What is traceability matrix?
Traceability matrices help ensure that each design element, typically documented in a Software Design Description (SDD), traces back to a software requirement that is the source or reason for having that element in the design. Traceability also helps ensure that all requirements are addressed in the design and that only what is required is designed.
What is requirements tracing?
For small projects without access to a requirements tool that includes tracing features and with time/budget limitations preventing them from acquiring a new tool and associated training, requirements tracing may be done with a spreadsheet (such as Excel), a simple database (such as Access) or a textual document. It is very important that the project be diligent about keeping such traces up to date as these methods do not include automatic updates when requirements, design elements, or other relevant documents change.
