Vertical traceability is a characteristic identifying the source of requirements typically from requirements to design, to the source code and to test cases. A traceability matrix in software testing — otherwise known as a test matrix — is used to prove that tests have been run. The medical device industry is heavily regulated by several agencies, including the FDA and ISO.
Or you can use specialized tools to accelerate the process. That means tracing forward from requirements to source code to test cases to test runs to issues. You should also be able to trace back from requirements to business goals or objectives (to answer why the requirement is there).

Explore the possibility to hire a dedicated R&D team that helps your company to scale product development. See for yourself how easy it can be to use traceability and create a traceability matrix. Software (e.g., flight data recorders) is increasingly embedded in hardware (e.g., a plane).
- So, you now know that requirement traceability is important.
- This can be used during the development process to prioritize the requirement, determining how valuable the requirement is to a specific user.
- Horizontal trace-ability matrix documents the inter-dependency between requirements.
- Software (e.g., flight data recorders) is increasingly embedded in hardware (e.g., a plane).
- Requirements traceability is important to effectively manage your requirements.
- And you’ll be able to manage the scope of your requirements.
Bring Stakeholders and team members together by allowing them to collaborate within the same space. Build online requirements reviews directly from within your horizontal traceability project. Invite Stakeholders and team members alike to request and facilitate change. Some traceability software — such as Helix ALM — automates the process.
Recovering traceability links in software artifact management systems using information retrieval methods
If any change in requirement happens, then it needs to be reflected across all the four browsers. These kind of dependent requirements are easily traceable if horizontal traceability is marked among them. To make it more clear horizontal traceability is a sibling kind of relationship while vertical traceability can be treated as parent-child relationship. A requirements traceability matrix is a document that demonstrates the relationship between requirements and other artifacts. It’s used to prove that requirements have been fulfilled. And it typically documents requirements, tests, test results, and issues.
Requirement traceability also helps your quality assurance (QA) team understand what needs to be tested. This improves test coverage by mapping test cases back to each requirement. So, QA will be able to test all of the right things. And, as a result, you’ll be able to show that your requirements have been properly implemented. In many projects, people use office tools like spreadsheets for managing traceability.
Dramatically reduced cost of ownership & eliminated other siloed tools
Horizontally traceable schedules support the calculation of activity and milestone dates and the identification of critical and near-critical paths. You can easily use this matrix to update relationships in your project, identify orphaned requirements, and ensure Test Coverage. This video shows you how to create an Intersection RTM using the work items from your project.
Prototype, wireframe, and mockup the interfaces your team needs to create. Use pre-built question lists to gather answers and turn them into robust and comprehensive requirements. Use this tool to write use Cases textually and automatically generate a Use Case Diagram.

In order to ensure traceability to artifact types beyond requirements, RM tools often allow to import other artifacts as surrogate requirements that can then be traced with the tool’s requirements tracing methods. The disadvantage of this approach is that different adapters or converters for the different artifact types are necessary that need to have a consistent version and data format. In contrast to ALM tools this consistency must be carried out oneself. Both horizontal and vertical traceability can be bidirectional. Establishing and maintaining robust vertical and horizontal requirements traceability helps to trace transmission of a change to all affected work products and customers/users. When a change in requirement happens, effective impact analysis is possible with the help a traceability matrix.
You can even use Helix ALM for traceability with Jira issues. There are different types of traceability matrices, depending on the desired use. Requirements traceability is important to effectively manage your requirements. Horizontal Matrices allow teams to easily identify issues using a broader perspective. Our packages are built to scale with your business over time.
Some automated traceability applications offer rather simple techniques, such as displaying a table alongside a text document or diagram that shows which requirements link to which test cases, but not allowing these relationships to be viewed in any dynamic way. Other applications offer more sophisticated traceability techniques, such as allowing the analyst to create quick diagrams linking various requirements together (with arrows to show forward and backward traceability). The system then reads this diagram and automatically embeds links between related requirements within a rich text document.
And you’ll be able to manage the scope of your requirements. By linking your requirements to tests, you’ll understand how you can realistically meet those requirements and still ship on time. Traceability can also be used for decision-making throughout product development. You’ll be able to understand how product design will be impacted by requirements. And, if a requirement changes, you’ll be able to analyze the impact of that change across development.
The emergence of requirements networks: the case for requirements inter-dependencies
Repository or tool stack integration can present a significant challenge to maintaining traceability in a dynamic system. In fact, the Intersection Matrix is objectively the fastest way to build relationships between two work items in Azure DevOps. This will allow you to increase coverage Requirements and their Test Cases, identify orphaned requirements and more. The Intersection Matrix allows you to easily update the relationships between two work items by adding a relationship where they intersect. Use the Reporting tool to type up the static content you would like included in your report, and add in the results of Azure DevOps queries. Ensure test coverage and traceability that is easily exported, and that is always up to date.
