Role of Requirements Traceability Matrix in Regulatory Compliance Across Industries

Requirements Traceability Matrix (RTM) - An Overview

The journey of a product or service begins with collecting requirements, designing the product, identifying the components needed, purchasing them, transferring the process to the manufacturing team, testing it, and then releasing it in the market. This entire journey is not always linear. Many back and forths are based on practical considerations such as usability, parts quality, quantity, manufacturing capabilities, etc. Therefore, at every stage, changes may be made. With every iteration, the possibility of the final product not meeting the initial requirements becomes stronger. This leads to nonconformance, rework, or complete rejection of the product.

To ensure conformance and the continued relationship between requirements and the components/subassemblies/functionality, the process needs to be documented and cover requirements, product tests, test findings, and issues. This is crucial for product quality, performance, and safety.

The traceability document provides easy access to information such as:

• Components
• Suppliers
• Inspection reports
• Manufacturing process
• Testing reports

End-to-end traceability enables the tracking and tracing of components, sub-assemblies, and assemblies from the time of purchase to the end product. This is an essential requirement of quality control and assurance for regulatory compliance. In addition to correcting errors, it also helps fulfill customer requirements.

RTM Requirements Across Industries

In different industries, the RTM requirements can vary based on the nature of operations and the risks of nonconformance.

• Construction: The workflow begins with project planning when the client's project requirements are defined and the project specifications are developed based on this. The design and engineering plans are detailed, with each design element linked to the specific project requirements. The plan is executed in the construction phase, after which the building is inspected to ensure conformance and compliance. Conformance includes tracing the results to the specific project requirements before handing over.
• Healthcare: The requirements for a new healthcare system or process are defined and aligned with patient safety and product quality standards. The product design and development is the next stage, with features traceable to clinical requirements, healthcare regulations, and regulatory standards. The device is tested using test cases, and the results are documented. The device is monitored continuously, and any change or update is validated by linking it to the original clinical requirements.
• Automotive: Once the requirements for a new vehicle model have been defined, they must be traced back to regulatory, safety, and performance standards. The specifications of the vehicle features are detailed and manufactured to align with the design and specifications.

Some of the regulatory standards for RTM include:

• ISO/IEC/IEEE 29148:2018: This provides guidelines for the documentation of system requirements, emphasizing the importance of traceability throughout the requirement engineering process.
• ISO 13485: This governs the medical device industry, providing guidelines for establishing a Quality Management System with traceability requirements. Changes to requirements must be documented, and the impact of those changes must be assessed.
• FDA: The US Food and Drug Administration Regulations for Medical Devices specifies regulations for developing and maintaining medical devices.
• DO-178C: Governing the aerospace industry, particularly for software development in airborne systems, it guides traceability and documentation of requirements throughout the software development life cycle.
• IEC 61508: This ensures the functional safety of electrical/electronic/programmable electronic safety-related systems, providing requirements for ensuring the safety of systems. Traceability is one of the important aspects of demonstrating compliance.

By complying with these standards and regulations, industries can ensure the final product’s quality and safety and demonstrate due diligence during audits or inspections. Project managers and teams must stay updated on the relevant standards and guidelines applicable to their industry to ensure effective traceability practices.

Role of RTM in Regulatory Compliance

Some of the critical factors that help businesses improve compliance with RTM include:

• Improved Transparency and Accountability: As the RTM document traces the journey of a component end-to-end across workflows, establishing a traceable link between regulatory requirements with associated controls and business processes. This enables establishing accountability and improved transparency in the processes.
• Risk Management: Aligning RTM with regulatory requirements enables businesses to determine potential compliance risks and implement controls proactively to mitigate them. This reduces non-compliance risk and increases product quality, safety, and performance.
• Enhanced Audit Efficiency: A well-documented RTM improves the effectiveness of audits as it enables the tracing of regulatory compliance easily, along with identifying risks and the corresponding controls implemented.

How to Make RTM Effective

For the RTM to improve compliance across industries, the quality leaders must identify applicable regulations and the key requirements to ensure compliance.

Once the applicable regulations are identified, organizations must define the necessary controls in policies and procedures, which will influence the implementation of technical safeguards, training programs, and other control measures.

The controls must be mapped to the relevant business processes or systems, which must also be documented in the RTM. Since regulatory compliance is ongoing, the RTM must be periodically reviewed and updated with changes to regulations, processes, or control measures.

Using a cloud-based solution for RTM can improve its effectiveness by improving visibility into processes, automating the RTM documentation process, integrating workflows, and enabling proactive risk and change management. A product lifecycle management software such as ComplianceQuest, aligned with leading regulations and standards, also facilitates changes to the RTM documentation process based on changes in the regulatory environment. This increases the compliance of manufacturing companies across industries.
