Matrix Req
Medical-device design control and requirements managementMatrix Req helps medical-device teams manage requirements, risks, tests, and design documentation in one AI-assisted system, with links between development items and generated technical documents.
Matrix Req's Traceability Checker goes beyond finding missing links: it evaluates whether existing item relationships hold and suggests what could fill each gap, bringing AI-assisted review directly into the design-control workflow.
Matrix Req goes beyond storing specifications: teams can define design categories and relationship rules, connect requirements with risks and tests, and identify broken or outdated links. Its design-control workflow includes change history, approvals, impact analysis, test protocols, and generated documentation. For teams with parallel development work, the product also supports project branching, merging, and reuse of items from existing projects.
The focused fit is regulated product development, so teams writing only general business specifications may prefer a general-purpose documentation tool. For example, a medical-device team migrating existing Excel or Word files can map their content into Matrix Req and preserve links among imported requirements, risks, tests, and specifications.
- +The website reports 28% time saved when writing, validating, and preparing technical documentation and audits.
- +Imports Excel columns or Word sections into Matrix Req fields while preserving links among requirements, risks, tests, and specifications.
