A 2,100-Hour Pre-Production Electronics Project

Building a medical device rarely follows the smooth, predictable trajectory presented in investor pitch decks. While regulatory consultants often default to "it depends," medical device teams require concrete figures regarding engineering hours, calendar timelines, and budget allocations to bring a concept to market safely and effectively.

Lisa Voronkova, co-founder of OVA Solutions, draws on a dataset from developing over 200 medical devices to pull back the curtain on hardware engineering realities. She outlines the four structured phases of engineering—Discovery, Proof of Concept, Design, and Development—explaining how disciplined phase-gate management mitigates costly late-stage redesigns and protects capital.

The conversation dives into transparent, real-world case studies ranging from short pre-production hardware tracks to complex, multi-year continuous glucose monitor (CGM) developments. Lisa and host Etienne Nichols explore the true financial scope of Design for Manufacturability (DFM), realistic blended hourly rates across global markets, and why shortcuts in early contextual validation often lead to catastrophic manufacturing overhead.

Takeaways

• Phase-Gate Discipline Controls Financial Risk: Moving into high-cost tooling or manufacturing before proving core function in a low-fidelity mock-up risks turning a $1,500 prototype adjustment into a $150,000 production mold tool rework.
• Validate in the Real Operating Environment: Conducting customer interviews is insufficient if engineers do not observe the actual clinical setting; lighting conditions, sterile field constraints, and physical workflows dictate foundational hardware requirements.
• Benchmark Engineering Hours accurately: Standard hardware projects generally fall into three tiers: 2,000–3,000 hours for simple electronics integrations, 5,000–6,000 hours for multi-system electro-mechanical devices, and 10,000–30,000+ hours for high-complexity Class II/III systems (e.g., CGMs, surgical robotics).
• DFM Accounts for a Massive Secondary Investment: Completing the initial "golden sample" prototype is only half the engineering journey; preparing a device for mass production (assembly sequences, test fixtures, second-sourcing components) can demand an additional 2,500 to 7,000+ engineering hours.
