When a change in requirement happens, effective impact analysis is possible with the help a traceability matrix. Thus we are in a better position to find adverse side effects due to a modification in a work product and ensure that the change did not hinder compliance with user requirements. Used in software testing and product development, a requirements traceability matrix is an important tool to make sure you fulfill every user requirement. No project should be without one, which is why we’ll take you through a step-by-step guide to making your own requirements traceability matrix. There is no one way to create a requirements traceability matrix, just as there is no perfect project. But using an RTM document will help you and your team dramatically.

horizontal traceability

Using requirements traceability, an implemented feature can be traced back to the person or group that wanted it during the requirements elicitation. This can be used during the development process to prioritize the horizontal traceability requirement, determining how valuable the requirement is to a specific user. It can also be used after the deployment to see why certain unused features found during user studies were required in the first place.

Tracing towards and beyond the requirements

The more complex your project, the more likely it is that you’ll encounter a considerable number of failures. That isn’t a bad thing, but it means that you should consider giving yourself room to describe your intended outcomes and potential errors. Project status goes hand-in-hand with test cases and requirements by allowing teams to implement traceability.

In the previous scenarios, decisions and values were predefined by the transformation that generates each test. Thus, although the decision element is retained for the sake of readability, only one path is given for each test. The proposed metamodel is similar to several existing metamodels mentioned in the Related Work section.

Building Query and Multiple Query Horizontal Matrices

The development team was made up of about 15 people (this number varied during the project) and each result had to be validated with the general project team. Any change during product definition or validation was therefore critical and a great effort was needed to manage the specific aspects affected by each change in the overall system. The traceability matrix provided great support for easily finding connections between artifacts and for evaluating their impact on the rest of the project. The matrix is still used whenever system maintenance is performed. The application of such an approach to traceability management is, then, clearly a task that has to be defined and implemented by the methodology expert. Once integrated in the tool, it will be transparent to software developers, who will only see a monitoring mechanism for dealing with trace conflicts.

Rempel & Mäder (2016) also focus on traceability difficulties, providing an assessment model and a comprehensive classification of possible traceability problems and assessment criteria for systematically detecting those problems. 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.

An analysis of the requirements traceability problem

The status of the project refers to the effectiveness of your tests. If the tests fail, you’ll need to record the issue and search for what caused the problem. Requirements traceability matrix documents are meant to simplify the project management process, and so uniform usage is important. IMedea (G7 Innovation, 2021) was briefly described in the Materials and Methods section of this paper.

Our software helps you plan, schedule and track work in real time. Stay on top of changes with notifications and even comment and share files across departments. Everyone is always working on the same page which helps productivity. Add to that features for task and resource management and you have an all-around project management software. Having the visibility of requirements traceability into requirements such as design, development, testing and support, minimizes negative outcomes and maximizes productivity.

The emergence of requirements networks: the case for requirements inter-dependencies

TraceableElement describes any artifact in a context model and is identified by its attribute name. In the example of the patient (Fig. 1), for instance, a TraceableElement might be the storage requirement (SR-01), the class (CL-01) or the database table (TL-01), but also their attributes. Intersection Matrices are used to quickly and easily manage, updated, and change the relationships between two sets of work items. This type of Matrix can be used to show you your requirements hierarchy and how higher-level work items, like Epics, decompose down into lower-level requirements, like Test Cases and Bugs. Traceability Matrices allow teams to visualize their requirements in a hierarchy, they allow teams to identify disconnected and orphaned requirements, and provide you with an an extra level of auditability. The Intersection Requirements Traceability Matrix allows you to identify and manage the relationships between the requirements in your project.

The industrial application of the approach would allow experiments to be organized within industry, offering an opportunity for further validation. The idea is to conduct controlled experiments in software companies to measure the value-added of this traceability approach for software development teams. As NDT is being used in several companies, we are confident of their experience and collaboration. The key aspects in traceability management are identification of products from the specific contexts to be traced and the creation and monitoring of the traces detected. 3 as context, tracing, and monitoring models, represented in turn by the UML classes ContextModel, TraceModel and MonitoringModel.

Requirements Traceability Matrix – RTM

The practical and project-related levels are presented later, in the Tool Support for Model-Driven Traceability section. One of the most commonly used techniques is the traceability matrix (TM). More challenging issues are how to maintain consistency in the TMs required for the target models in case of changes in the source models and the implications that changes in the target models may have for the source models. It is always possible to completely regenerate target models and TMs, but this solution is neither economic nor possible if the target models have been adjusted. ProjectManager is award-winning project management software that helps you work more productively and track that work to stay on schedule.

  • Traceability is defined by Drivalos-Matragkas et al. (2010) as the ability to chronologically interrelate uniquely identifiable entities in a way that matters.
  • This is the bare minimum and you can add more as needed for your project.
  • The process of enriching methodology M with the proposed MDE-based traceability approach is mainly an activity that has to be performed just once by the methodology expert, or, exceptionally, more than once in the case of improvements to M.
  • The first time a patient attends a clinic, a set of standardized data corresponding to that patient’s clinical history is collected.
  • In both cases, a warning message alerts the user about the changes.
  • Connect teams, departments and even outside vendors to facilitate communication and keep everyone working better together.

When pulling in the information for your Intersection RTM, you might want to visualize one-to-many or many-to-many relationships. The only way to do this is to populate the columns and rows of your Intersection RTM using queries.


The Intersection Matrix will reflect any current relationships that exist between two work items. The Intersection Matrix allows you to easily update the relationships between two work items by adding a relationship where they intersect. For each test case, you’ll need to outline the steps to analysis, the intended result, and the post-test outcome. No matter what project you’re pursuing, though, you must include a few basic elements. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Whether an organization chooses to adopt a matrix or automated system, the efficacy of either method is greatly benefit from best practices.
