Tools

Engineering calculators and planning tools for mechanical design, verification, and regulated product development.

Planning Tools
Design control documentation for medical device development — traceability, risk analysis, and V&V planning aligned with FDA 21 CFR Part 820, ISO 13485, and ISO 14971.
Design Control
Requirements Traceability
Map user needs through system requirements, design inputs/outputs, verification methods, and acceptance criteria — with regulatory clause traceability, development phase tracking, and trace-health scoring for FDA 21 CFR Part 820.30 and ISO 13485 submissions.
Launch tool
Risk Analysis
FMEA Risk Analysis
Build DFMEA/PFMEA risk tables with severity, occurrence, detection, RPN scoring, hazardous situation and harm analysis, residual risk acceptability per ISO 14971, mitigation ownership, and CSV export for design history files.
Launch tool
V&V Planning
Design Verification Planner
Plan verification and validation activities by requirement — specify V&V type, test phase, sample rationale, acceptance criteria, protocol IDs, regulatory clause references, and evidence links for FDA submission and ISO 13485 design control packages.
Launch tool
Test Methods
Test Protocol Library
Define test protocols from design requirement to measurable output — specify test conditions, equipment, acceptance criteria, and sample rationale. Cross-link each protocol to V&V plan entries (DV-xxx), requirements (REQ-xxx), and FMEA risk controls (FM/UR/PF-xxx) with clickable badges across all planning tools.
Launch tool
Quality System
ISO 13485 Checklist
Clause-by-clause audit-readiness tracker for ISO 13485:2016 §§4–8 — capture status, owner, and evidence reference for every QMS requirement. Custom rows for organization-specific obligations; cross-links into the FMEA, traceability, and design-verification tools.
