The quality/ability/extent of being traceable.
Traceability in systems refers to the ability to track and follow the history, application, or location of an item or activity through recorded data. This ensures that each stage of the system's lifecycle can be connected to its preceding and subsequent stages.
As a system quality attribute, traceability enhances the system's reliability, maintainability, and accountability by allowing the origin and path of requirements, design elements, code, and tests to be documented and followed.
- Requirements Traceability: The ability to link requirements to their source and to their corresponding implementation and verification elements.
- Version Control: Maintaining detailed records of changes to the system, including who made the changes and why.
- Impact Analysis: Assessing the potential consequences of changes in one part of the system on other parts.
As a non-functional requirement (NFR), traceability specifies the need for mechanisms and processes that allow for the tracking and linking of all aspects of the system throughout its lifecycle.
- Documentation: Comprehensive documentation that details the relationships between requirements, design, code, and tests.
- Traceability Matrix: A tool used to ensure that all requirements are covered by appropriate design elements, code modules, and tests.
- Change Management: Processes and tools for tracking changes and their impacts throughout the system lifecycle.
As a cross-functional constraint, traceability requires the involvement of multiple teams and stakeholders to ensure consistent tracking and linking of all system elements across different phases and components.
- Interdepartmental Collaboration: Ensuring coordination among teams (e.g., developers, testers, project managers) to maintain traceability throughout the system lifecycle.
- Tool Integration: Using integrated tools that facilitate traceability across different phases (e.g., requirements management, version control, testing).
- Standards and Practices: Establishing and enforcing standards and practices for maintaining traceability throughout the system.
To implement traceability:
- Establish Clear Processes: Define clear processes for capturing, documenting, and maintaining traceability links from requirements through to testing.
- Use Traceability Tools: Implement tools that support traceability, such as requirements management software, version control systems, and traceability matrices.
- Create and Maintain Documentation: Develop comprehensive documentation that outlines the traceability links and ensures it is regularly updated.
- Integrate Traceability into Workflows: Ensure that traceability is an integral part of the development, testing, and maintenance workflows.
- Conduct Regular Reviews and Audits: Periodically review and audit traceability links to ensure they are accurate and complete.
- Train Stakeholders: Provide training to all stakeholders on the importance of traceability and how to use the tools and processes effectively.
- Monitor and Improve: Continuously monitor the effectiveness of traceability efforts and make improvements based on feedback and evolving needs.

Dictionary: trace: Trace. to follow the footprints, track, or traces of. to follow, make out, or determine the course or line of, especially by going backward from the latest evidence, nearest existence, etc. to go back in history, ancestry, or origin; date back in time.
Define traceable: Traceable refers to the ability to track and follow the activities, transactions or changes made in a computer or software system. It involves recording and storing relevant data and information that can be used to identify the source of an issue, facilitate troubleshooting or diagnose problems in the system. Traceability is crucial in ensuring data integrity, system security, regulatory compliance, and quality control in software development and maintenance. It also helps to improve transparency and accountability in the use of computer and software resources.
