What is Requirement Traceability Matrix and Why You Should Use it in Project Management
The Standish CHAOS Report states that 71%
of software projects fail due to poor requirements management. We can imagine this number
being much higher when we consider all industries. Project failure leads to wasted
investments and time, frustrated employees, a bad reputation, and lost revenue.
Project managers often play the blame game and say things like “we couldn’t get
all the information” or “The requirements kept changing.” But that’s
the reality — in any project, there are multiple stakeholders and the requirements may
change on the go because of the evolving business environment.
So, how can we make sure the project you’ve made works, meets all the agreed upon
requirements, and is able to accommodate changes along the way? The easiest way to go about
this is by building a requirement traceability matrix.
Read more to learn about what a requirement traceability matrix is and how you can create one
for your business.
What is the Requirement Traceability Matrix (RTM)?
The easiest way to define a requirement traceability matrix (RTM) is that it’s a
scientific tool, often in the form of a document or chart, that serves as a record of all
project specs. This document tracks project scope, deliverables, and demand from the start
to the end of a project cycle.
Managing a project is stressful and trying to catch every “what-if” situation to
ensure the project doesn’t derail adds more burden on the shoulders of a project
manager. The RTM decreases the stress and pressure of managing and executing projects
because it captures all demands from all stakeholders throughout the project
lifecycle.
A company can use a traceability matrix in any of the following scenarios:
To develop project/product requirements
To test quality and ensure the final product is error free and does what it’s
supposed to do
To conduct a risk analysis
To create a proposal or project plan
To meet compliance protocols
To create testing standards
In the software and manufacturing industries, it’s common to develop a requirement
matrix to ensure that the software or product is tested at the appropriate level. For
instance, in a medical device company, the RTM can be used to check if the equipment is
functioning correctly and meeting the standards of the medical industry.
What an RTM does
An RTM performs the following functions in a project:
Demonstrates the relationship between requirements and other artifacts
Document requirements, tests, test results, and issues
Tracks the requirement, its source, shifts, and how the requirements will be delivered
throughout the project life cycle
Tracks requirements across all stages of the project
Assess the success of the project
Different Types of Traceability
There are three types of requirement traceability most commonly used in project management:
forward, backward, and bidirectional. We will explain each type in more detail.
Forward Traceability: Most commonly used to trace a requirement to a
test or future movement. It ensures that the project is tested thoroughly. Let’s
take an example of a new type of running shoe that is supposed to increase your speed by
2%. Each feature and design of the shoe will be tested to make sure it’s meeting
the specs.
Backward Traceability: This is exactly the opposite of forward
traceability, where you are mapping each test case to a requirement. This type of
traceability is favored in scenarios where there is a risk of “over-doing”
the initial requirements and scope. An example of this can be found in the baking
industry, where once a unique recipe is developed, it’s then taken back through
the chain to identify the steps, ingredients, suppliers, etc, utilized.
Bidirectional Traceability: As the name states, this form of
traceability combines both forward and backward methods. So each requirement or spec can
be linked to a forward test case and vise-versa. We recommend bidirectional traceability
to ensure the highest chance of project success.
Various Components Requirement Traceability Matrix
As mentioned earlier, the RTM is typically a table or chart that lists each spec in a
separate row, against its testing process. The RTM is designed as per the company’s
specific standards, however, there are some essential components that are applicable in all
frameworks.
Requirement Identification (ID) - A numerical identification of
the specification. Using a standardized code system makes it easy to manage
this.
Requirement Type - Which department or function does this specification
fall under?
Requirement Description - Brief description of the requirement. It
could be “send automated e-mail” or “running shoes should dry in X
time”
Test Case Identification (ID) - Much like the requirement ID, assign a
numerical or alphabetical test ID code to each spec.
Test Results - Document whether the test case ID passed, failed, or is
in-process against each requirement ID.
Notes - A column to add any specific notes. You can choose to
include Details about why the test failed or passed in this
part.
In some cases, a company might decide on including the following fields in their traceability
matrix as well: requesting department/client, project objective, and/or design status.
The following table gives an example of a Requirement Traceability Matrix.

Advantages of a Requirement Traceability Matrix
What does having a requirement traceability matrix bring to your organization and project
management? First of all, an RTM is an important component of project documentation that
helps you deliver projects that meet the end-goal. If you want to consistently deliver
high-quality solutions for clients, you’d want to create a RTM.
Other benefits of creating a RTM are:
Helps You Stay On Track
One can look at the RTM as a document that dictates project direction and timing. The process
of mapping out the requirements and related testing processes keeps the project on track.
For project managers, the RTM aids in managing the scope of requirements. They can also
assess if the requirements are realistic in comparison to the deadline. Another benefit of
the RTM is that it eliminates the scenarios of adding too many unnecessary bells and
whistles to a product as that can impact the delivery deadline.
Improves Planning
One increases the chance of project success when things are planned well. With an RTM, each
job specification is accounted for, tested, and improved upon. The matrix also highlights
interdependencies amongst the tasks. This can provide insight into how the entire project
will be impacted if there’s a change to any of the requirements.
Provides Better Documentation
The RTM provides a complete and succinct documentation of the entire project cycle and
performance. The chart can make it easier to identify and rectify errors. Also, the data
captured in the RTM can be presented to a client or even used for future planning.
Aids in Understanding Test Requirements
With an RTM, you know what you’re testing, how, and why. The document also helps you
ensure the tests are valid and reliable. The documents also logs testing bugs and solutions
which can again be used for future project planning. Through testing of all features reduces
defects and improves product quality. All of this leads to greater customer
satisfaction.
Fosters Communication and Collaboration
The RTM also serves as a single source of truth for project information that can be shared
with all stakeholders. The clear listing of each requirement eliminates communication and
confusion. It also identifies which person or team is responsible for that feature so any
concerns can be taken up with the right resource.
4 Steps to Create a Requirement Traceability Matrix
Eager to create a requirement traceability matrix and eliminate confusion, build
accountability, and increase project efficiency? Follow our simple four steps, and you will
be on your way to experiencing the benefits of the RTM.
Step 1: Identify RTM Goals
Before you start using an RTM, you should know why you are gravitating towards it. What is it
that the RTM will help you achieve? Reduce product defects? Ensure thorough testing? Or make
sure that the final product meets the requirements put forth by the customer?
Step 2: List out Client Goal and all Requirements
Now it’s about knowing the client’s goal and listing out all requirements
pertaining to it. Is your client a clothing brand and they want you to create an app for a
seamless shopping experience? In this case, the key points will be having all products
listed along with pictures and detailed description, quick loading app, and a functioning
payment gateway.
Speak to the customer, customer’s clients, and other experts to build a detailed list
of requirements. Each requirement should include an unambiguous description of its
functionality and purpose.
Step 3: Create a Chart or use a Template
Use a dedicated RTM tool, like a software or app, or a template, to create your chart. A
quick Google search will yield free templates that can be downloaded and customized.

A requirement traceability matrix can also be built on Excel, just remember to include all
the relevant
components (mentioned earlier in the blog) in it. The only issue with using Excel to
manage your RTM is that all changes need to be entered in manually which can be an
administrative headache. Excel sheets are also prone to human error.
This YouTube video on creating the RTM on Excel has some helpful tips.
Step 4: Complete, Track, and Modify Matrix as per Needs
Once you have created the chart, complete all the fields with as much detail as possible. As
the project progresses and requirements evolve, update the RTM to reflect the changes. This
includes adding new requirements, modifying existing ones, and linking them to the
appropriate artifacts. Regularly review and maintain the RTM to ensure it remains accurate
and up-to-date.
We would again like to point out that the RTM is a live document that should be updated
throughout the project's lifecycle to reflect changes. This will keep the document as a
single source of truth and maintain the integrity of the traceability links. Keeping the
document updated ensures that requirements are not overlooked, are implemented correctly,
and are adequately tested. All these factors contribute to the successful delivery of the
project.
Pairing Requirement Traceability Matrix with Resource Management Software
To gain even more insights and advantages, it can be wise to pair your RTM with a resource management software. Here’s how combining the two can be beneficial to your project outcomes:
Enhanced Project Visibility:
By integrating them, you gain a comprehensive view of the project, linking requirements with the resources needed for their fulfillment. This allows for better planning and allocation of resources based on prioritized requirements.
Improved Resource Management:
Knowing which requirements need what resources, allows for efficient allocation of personnel, skills, and time. As a project leader, you can quickly identify resource gaps. For instance, if a project requires a data analyst, but you don’t have another analyst on the team, you know it’s time to hire one or increase training initiatives.
Also, if a crucial resource is unavailable, the integrated RMT and resource allocation platform will highlight alternative resources or adjust the project schedule to mitigate any potential impact.
Increased Efficiency:
With employee management software, you will first be able to identify the best resource for each specific requirement. Not only that, but you will get a gauge on how many resources will be required. With this information, you can estimate project timelines and budgets more accurately. The combination of RTM and resource allocation tools reduces waste and improves project delivery efficiency.
Reduced Risk:
Visibility of resource utilization against requirements helps identify potential bottlenecks and risks early on. With this knowledge, you can take corrective actions before project completion is jeopardized. For instance, you will be able to see if a specific resource is overloaded with multiple testing requirements. Straining one resource can create errors, reduce productivity, and increase stress. As a project manager, you can step in and reduce their workload.
Enhanced Collaboration:
Integrating RTM with resource management software facilitates communication and collaboration between team members. Each member can easily see what resources are assigned to which requirements, and who has expertise in certain areas. This visibility fosters team communication and accountability.
The RTM and resource management software, when paired together, create a powerful synergy that enhances project visibility, optimizes resource allocation, improves decision-making, and delivers projects on time and within budget.
