Requirements traceability matrix: what is it and why it is useful?
When managing a project, it is essential to be able to visualize the relationships between its requirements, and objects. They guide the path of product development to meet the needs of stakeholders. In this scenario, knowing how to create a requirement traceability matrix is essential.
What is requirement traceability matrix (RTM)?
The Requirements Traceability Matrix is a document that links requirements throughout the validation procedure. It is the model which used to visualize the evolution of different requirements and their points of intersection. As it is common to change these items during the execution of the project, it becomes easier to see whether it will be necessary to promote changes without missing any important item.
The traceability matrix must be made after determining these items. It is natural that there is a refinement of these needs, but the matrix does not leave the origin. And, the reason for the requirement to be lost. Thus, there is a guarantee that the project and business objectives will be aligned at the time of delivery.
How to identify the requirements?
The identification of requirements require, mainly, the evaluation among all those involved in the project. Without planning being carried out by a well-integrated team of leaders, chances are high that expectations will not be aligned. And the result will not be well evaluated. To start defining the requirements of the project, it is important to know the existing types. They are –
- Functional requirements– which are related to the behaviour of a project or the outcome of a project. If the project involves creating a system, for example, the need for the tool to display an error message whenever a failure occurs is a functional requirement.
- Non-functional requirements– which address product properties. The obligation for this alert to be accompanied by a sound is a non-functional design requirement.
Conclusion: Why it is necessary?
Going beyond the continuous exchange of information between those involved, the survey and registration of project requirements may adopt some strategies. They make information more accurate and improve the quality of implemented project management practices. We can point out as the main approaches –
- Analysis of the business profile
- Documentation of all requirements
- Classification of requirements into priority levels
These three points are addressed by the project requirements traceability matrix. It is one of the most intelligent methods that the business can adopt to follow the objectives of each stage.
