Your Design History File is not a folder; it is a web of interconnected decisions, risks, and test results. For many teams, especially those scaling quickly, that web is a tangled mess of Word documents, Excel spreadsheets, and disconnected Jira tickets. Here is why a leading ventilator company, Hamilton Medical, is investing in a major systems overhaul to prevent this exact problem.
What the Announcement Says
Hamilton Medical, a major player in critical care ventilation, just announced they are adopting PTC's Codebeamer, an Application Lifecycle Management (ALM) solution. They are integrating it with their existing Windchill Product Lifecycle Management (PLM) system. The goal is to replace legacy systems and paper based processes to create what the industry calls a “single source of truth” for product development.
This move is designed to create automated traceability across their engineering, risk, quality, and V&V teams. In short, they are building a digital thread that connects every requirement to every piece of code, every risk mitigation, and every test case. It is a proactive move to ensure they are always prepared for an audit and can manage the immense complexity of modern medical device development.
The Failure Mode They're Preventing
This is not a story about a recall; it is a story about preventing one. The silent failure mode that Hamilton Medical is addressing is broken traceability. When an auditor asks you to prove that a specific software requirement was tested and that the test passed, the scramble begins. Engineers dig through old emails, search network drives for test reports, and manually piece together the story. This is not just inefficient; it is dangerous.
A broken traceability chain means you cannot be certain that you have tested every risk control or implemented every safety critical requirement. It makes it nearly impossible to assess the impact of a proposed change. A seemingly small software update could have unintended consequences on a critical risk mitigation, and without a connected system, that link can be easily missed until it is too late. This investment is an insurance policy against that kind of systemic failure.
Regulatory & Standards Context
This initiative hits directly at the heart of FDA 21 CFR 820.30 (Design Controls). This regulation requires manufacturers to establish and maintain procedures to control the design of the device in order to ensure that specified design requirements are met. A key part of this is the requirement for traceability from user needs all the way through to validated design.
For a software intensive device like a ventilator, IEC 62304 is also paramount. This standard for medical device software lifecycle processes is obsessed with traceability. It demands clear links between software requirements, software architecture, detailed design, and the tests that verify them. Manually maintaining this level of documentation for hundreds or thousands of requirements is brutally difficult. ALM tools like the one Hamilton Medical is adopting are purpose built to enforce the discipline required by these standards.
Design Playbook - Learning from the Event
Audit: Can you instantly generate a complete traceability matrix for any requirement?
If an auditor picked a random high level user need from your file, how long would it take you to show them every downstream design input, design output, risk control, and V&V test case associated with it? If the answer is measured in days of manual effort instead of minutes of running a report, your process is a liability.
Check: When a test case fails, does your system automatically flag the associated requirements?
Modern ALM platforms can create these links. A single failed verification test should ripple backward, putting a hold or question mark on all the requirements it was meant to satisfy. This prevents a product from being released with known gaps in its verification evidence, a common and critical manufacturing escape.
Audit: How much engineering time was spent manually compiling DHF documents for your last audit or submission?
Calculate the cost of that activity in man hours. That number is the ROI for investing in a more integrated system. Engineers should be spending their time solving technical problems, not acting as document librarians. This is a direct measure of the friction and inefficiency in your current process.
Check: Are your risk controls from your FMEA explicitly linked to the verification tests that prove they are effective?
It is not enough to just list a risk mitigation like “add an alarm.” You must have a formal link from that mitigation in your risk file to a specific test case in your V&V plan that challenges the system and proves the alarm works as intended under defined failure conditions. This link is non negotiable.
