Structuring the Documentation Process

When structuring the documentation process, establishing a methodical approach to manage and organize documentation is paramount. This involves creating a strategic map, which defines the flow of document creation, review, approval, and revision cycles. It is essential to interlink the various stages of documentation to maintain a cohesive and compliant record trail, underpinned by a robust document control system that ensures documents are current and retrievable.

The organization of documentation must consider an item-based methodology, where each information item serves as a fundamental building block in the documentation architecture. By linking related items—such as design requirements to risk assessments, or test cases to validation protocols—developers create a traceable and dynamic documentation system. In this system, real-time updates to one item cascade through associated documents, maintaining accurate record integrity that is essential for regulatory scrutiny and quality assurance throughout the product realization process.

Essential Documents for Medical Device Realisation

To ensure compliance with ISO 13485, MDR, and FDA regulations, a comprehensive suite of documents is integral throughout the entire medical device product realization process. These documents serve as a roadmap, guiding developers from the initial concept to post-market surveillance, while also ensuring traceability and meeting verification and validation requirements.

The product realisation process begins with the Design and Development Plan, which outlines the overall strategy and approach. This is followed by the creation of various documents, including Inputs, Outputs, Reviews, Verification, Validation, and Transfer records, which capture the necessary information at each stage of development.

For a seamless transition from concept to a market-ready product, it is crucial to have well-documented Product Requirements Specifications (PRS), Risk Management Files, and Clinical Evaluation Reports (CER). These documents not only demonstrate compliance with regulatory obligations but also serve as evidence during audits.

To achieve traceability and meet verification and validation requirements, it is essential to establish clear links between the documents and information sources. This includes the need for also linking requirements to risks, technical specifications, and user requirements. Using documents as information base, makes is almost impossible to trace how requirements are implemented and verified throughout the product realization process. Manually keeping track with lists of identifiable single requirements, specifications etc. is a hard challenge for developers and document managers and bears high risk of errors in each step.

By utilising an item-based approach, such as the one offered by Matrix Requirements with MatrixALM, developers can effectively manage and update their documentation.
