KEY TAKEAWAYS
Anyone working in app development or product design knows the challenge of keeping track of feature testing, client expectations, and defects throughout the project. A requirements traceability matrix (RTM) organizes that process by linking every requirement to its related tests, deliverables, and outcomes so nothing gets overlooked during development. If you have never created one before, this guide explains what an RTM is, why it matters, and how to build one.
What is a requirements traceability matrix?
A requirements traceability matrix (RTM) is a document that maps each project requirement to its corresponding deliverable, test case, or objective throughout the entire project lifecycle. It acts as a visual reference, typically plotted on a spreadsheet or software dashboard, with columns tracking each requirement alongside its source, current status, and verification method.
Software development and QA teams use an RTM to verify that every requirement is addressed at each phase of the project, whether they’re building a client-facing product or an internal tool. This keeps project outcomes aligned with client expectations and enables project managers to manage scope effectively while preserving quality standards.
Key elements of a requirements traceability matrix
, each working together to link every project requirement back to its origin and validation method. Understanding these components is essential for building an RTM early in the project. Below is a breakdown of the main components and what each one captures.
| Component | Description |
| Requirement ID | A unique code assigned to each requirement for easy reference and tracking. |
| Requirement description | A brief statement explaining what the requirement is and its role in the project. |
| Source | The origin of the requirement, such as a stakeholder, regulation, or internal document. |
| Priority | How critical the requirement is relative to project goals or deadlines. |
| Status | The current state of the requirement, such as planned, in progress, or completed. |
| Verification method | How the team confirms the requirement has been met, whether through testing, review, or sign-off. |
| Owner or assignee | The person or team responsible for delivering or validating the requirement. |
| Comments or notes | Additional context, updates, or changes the team should be aware of. |
Who needs the requirements traceability matrix?
RTMs are widely used among software developers, product teams, and professionals managing highly complex or regulated projects. While a more general project does typically track requirements, an RTM serves technical teams that must test and validate specific features.
Below are a few key sectors that rely on it to maintain oversight of deliverables and meet strict regulatory or quality standards.
- Healthcare
Pharmaceutical organizations use RTMs to verify that medical devices and clinical systems comply with FDA and ISO standards. This keeps every requirement documented and traceable, which is critical for product safety approvals and regulatory audits. - Information technology and software development
IT and software teams use RTMs to connect user requirements to technical specs and test cases. This ensures the final product reflects the client’s original requirements, even as requirements evolve through each project phase. - Construction and engineering Engineering firms use RTMs to track design requirements against safety standards, building codes, and project specifications. This ensures every deliverable meets regulatory requirements and reduces the risk of costly design changes later in the project.
- Finance and banking
Banks and financial institutions use RTMs to verify that systems meet data protection laws, risk controls, and security standards. This gives compliance and audit teams a record of how each technical or operational requirement was addressed.
Beyond these industries, any project team managing complex requirements can use an RTM to keep stakeholder needs tied to project objectives. Smartsheet offers a range of RTM templates suited for software development, agile workflows, and general project tracking to help you get started.
What are the types of requirements traceability matrix?
RTMs come in different forms depending on how requirements need to be tracked and validated. Here is a quick overview of the main types and how each one is used across different projects.
1. Forward traceability matrix
This matrix maps each requirement to the deliverable or test case that fulfills it, so every requirement leads to an output within the project.
Real-life example: Software developers use a forward matrix to link user requirements to code modules. This confirms each function delivers the intended value and that no feature is built outside the agreed project scope.
2. Backward traceability matrix
A backward matrix traces deliverables or test results back to their requirements. This helps teams confirm that every output in the project has a documented reason for existing.
Example: Product launch teams use a backward matrix to verify that every feature in the final release ties directly to a customer requirement. This ensures development efforts reflect market needs and that no resources were spent on features without measurable value.
3. Bidirectional traceability matrix
This type combines forward and backward traceability to confirm that every requirement is implemented and that each deliverable corresponds to a documented need.
Example: In medical technology, a bidirectional matrix connects regulatory requirements to test results. This validates every safety or quality requirement is tested and approved before the product reaches healthcare providers.
How to create a requirements traceability matrix
If you prefer to build your own requirements traceability matrix from scratch, follow these steps:
- Identify project requirements – Collect all technical requirements from stakeholders and project documents. Note which items are mandatory and which are optional to set priorities and understand dependencies for later phases.
- Categorize requirements for complex or multi-stage projects – Group related requirements so large projects are easier to manage. This helps teams understand how each requirement contribute to a specific project phase.
- Assign unique identifiers – Give each requirement a unique ID or label to streamline tracking as requirements evolve or when multiple teams work on the same project. A consistent naming system also helps link tasks to the outcomes they support.
- Define sources and stakeholders – Record who requested each requirement and who is responsible for approving or implementing it. This makes future updates easier to trace back to the right owner.
- Link requirements to deliverables – Connect each requirement to its related output, such as a product feature or test scenario, to confirm that every deliverable has a specific requirement behind it.
- Add verification and validation criteria – Specify how each requirement will be validated, whether through testing, inspection, or review. This gives the team a clear standard to measure each requirement against.
- Monitor status and update progress – Track each requirement using status categories like planned, in progress, or complete. Consistent updates help in spotting risks or delays before they affect delivery.
Project management platforms like Wrike simplify requirements management with tools that categorize and track project files. Its built-in templates let you group requirements by folder hierarchies and capture new requests using customizable forms.

FAQs
An RTM should be produced early in the project lifecycle once stakeholders and the project team have agreed on goals and specifications. Building it during planning phase ensures every requirement is captured and traced correctly before execution begins.
A requirements traceability matrix typically includes the requirement ID, description, source, test cases, and status. Additional fields like ownership and comments can be added depending on the project complexity and the level of detail required.
The three types are forward, backward, and bidirectional traceability. Forward connects requirements to deliverables, backward traces deliverables back to requirements, and bidirectional covers both forward and backward directions.
