The Essential Guide to Requirements Management and Traceability
What is Traceability?
The Definition
Requirements traceability is the ability to track and document the lineage and history of requirements throughout the development process. It provides forward and backward visibility into all activities surrounding each requirement, including design, development, testing, and support, by keeping track of components, parts, materials, and processes involved in the product’s creation. This documented thread helps minimize the risk of negative outcomes, maximize productivity, and ensure that products meet required specifications and standards. Benefits include greater team efficiency, easier regulatory compliance, and higher-quality products, and it allows for quick identification and resolution of any defects or problems.
What is the Purpose and Importance of Traceability?
Traceability enables product teams to associate a specific requirement with all the related project artifacts, as well as other requirements, both forward and backward, so that anyone can see how the activity relates to the requirement — and vice versa — at any point during development. This functionality, also called live traceability, fosters team collaboration and enables early detection of possible production risks.
Think of it this way: How important is it to have your products developed correctly in terms of definition, quality, and timing? Mission critical, right? That’s why requirements traceability is so critical.
Traceability is particularly important in industries such as aerospace, automotive, and medical devices, where safety, quality, and compliance are critical. In these industries, traceability systems are often mandated by regulatory bodies to ensure that products are safe, reliable, and comply with applicable standards and regulations.
Let’s take a look at some of the benefits of requirements traceability throughout the development process. For example:
- Simplifies project estimates
- Enhances process visibility
- Increases development efficiency
- Improves impact analysis of change
- Demonstrates verification and validation
- Strengthens product quality
- Proves compliance or functional safety
A single line of sight on a requirement, or a digital thread, is supremely important for application lifecycle management (ALM) and product lifecycle management (PLM). Both endure tight timelines and increasing numbers of requirements — including those from regulations, where compliance is non-negotiable.
Traceability is particularly important in industries such as aerospace, automotive, and medical devices, where safety, quality, and compliance are critical. In these industries, traceable systems are often mandated by regulatory bodies to ensure that products are safe, reliable, and comply with applicable standards and regulations.
Knowing the relationship between requirements, risk, tests, and so forth, is the difference between developing a compliant product on time and getting stuck in rework, delaying launches, and dealing with unhappy stakeholders. With requirements traceability, you don’t have to compromise on speed or quality.
The bottom line is that end-to-end traceability confirms you’re building the right thing and helps you prove compliance or functional safety. Without it, your development efficiency and product quality are in jeopardy.
What is a Traceable System?
A traceable product or system is one that has a documented history or record of its development, production, and testing. This record provides a complete picture of the product or system, including its design, components, and any modifications or changes made throughout its development. A traceable system also enables organizations to quickly identify the source of any issues or problems that arise during production or testing, and to take corrective action as needed.
Forward, backward, and bidirectional: The mechanics of creating a digital thread with traceability
To connect all the phases of the development process, from customer needs through support, four distinct kinds of links must be used to thread the process end-to-end. This includes high-level requirements as well as derived requirements — those not specifically defined but necessary for meeting defined requirements or having the system work as expected. Derived requirements must also be adequately traced to reap the full benefits of Live Traceability™.
Forward
There are two kinds of forward traceability: forward to requirements and forward from requirements. They both trace from an upstream component to downstream artifacts. The difference is in where they begin.
Forward to requirements traces from customer need to requirements. This is important because customer needs can evolve over time. If they do, requirements may need to change as a result. Following this type of forward traceability enables teams to be informed of changes in priorities at any time throughout development.
Forward from requirements traces relationships between requirements and corresponding downstream artifacts, including test cases. This type of trace ensures that each requirement is not only satisfied but verified and validated.
Backward
Like forward, there are two kinds of backward traceability. This pair traces from an endpoint, or downstream work product, to upstream elements. These two types have differing starting points.
Backward from requirements gives insight on how a requirement came to be by linking the requirement to the customer use case it addresses. This enables teams to improve decision making by understanding the origin of a requirement.
Backward to requirements begins at performed work and traces to its requirement. It gives visibility into why specific items were created and how different pieces of a system fit together. Tracing in this way also allows testers to find gaps or missing requirements.
Bidirectional
Bidirectional requirements traceability is the ability to perform both forward and backward traceability. Bidirectional is optimal because it gives teams full visibility from requirements specifications through building, testing, changes, defects, and back again. Traceability of this caliber can only be achieved through automated requirements management tools, such as Jama Connect®.
What Are the Benefits of Traceability?
The benefits of traceability are many. First, it ensures product quality by enabling organizations to track and verify that all components and processes meet the required standards and specifications. This helps to reduce the risk of defects and recalls, which can be costly in terms of both financial losses and damage to a company’s reputation.
Second, traceability helps to ensure compliance with regulatory requirements. In many industries, organizations are required to maintain detailed records of their products and processes and to demonstrate that they are meeting all applicable standards and regulations. A traceable system provides a way to easily produce these records and demonstrate compliance.
Third, it promotes accountability and transparency. By maintaining a complete record of a product’s development and testing, organizations can demonstrate that they are taking steps to ensure quality and safety. This can help to build trust with customers and stakeholders and enhance a company’s reputation.
How Do You Enable Traceability?
In practice, traceability involves the use of tools and systems to track and document the various components and processes involved in product development and testing. These tools can range from simple spreadsheets and databases to modern requirements management platforms that generate Live Traceability™ that integrate with other product development tools such as product lifecycle management (PLM) systems, test management tools, and task management tools like Atlassian Jira and Azure DevOps.
Challenges in Implementing Traceability
One of the key challenges in implementing traceability is ensuring that all relevant data is captured and documented. This can be particularly difficult in complex product development processes involving multiple teams, suppliers, and partners. However, by establishing clear processes and standards for data capture and documentation, organizations can overcome these challenges and reap the benefits of traceability.
In conclusion, traceability is a critical aspect of product and system development that enables organizations to ensure product quality, compliance, and accountability. By maintaining a complete record of a product’s development and testing, organizations can reduce the risk of defects and recalls, demonstrate compliance with regulatory requirements, and build trust with customers and stakeholders. While implementing a traceability system manually is very challenging, using a modern platform like Jama Connect automatically creates Live Traceability throughout the development process.
