RESOURCE ALLOCATION & TEAM INVOLVEMENT

Successfully bringing a medical device to market requires a cross-functional team with expertise spanning engineering, clinical insight, regulatory strategy, and commercialization. At this early concept stage, planning for the right contributors at each phase helps avoid gaps that can delay development or increase risk.

Because your device involves basic electronics, pressure control, and regulatory compliance, your development team doesn’t need to be large, but it must be well-coordinated. Below is a breakdown of the key functions you’ll need to cover, along with when they typically become essential.

Core Functional Roles

Team Structure Tips for Early Inventors

• Start Lean but Specialized
  At the concept stage, 1–2 versatile engineers (mechanical + electrical) and a part-time regulatory advisor can move things forward without overextending resources.
• Outsource Strategically
  Consider outsourcing firmware development, regulatory submissions, or specific test protocols if you don’t have in-house bandwidth but keep a clear scope and deliverables.
• Engage Manufacturing Early
  Even if full production is months away, early DFM consultation can reduce iteration cycles and avoid costly redesigns after verification testing.
• Don’t Delay Clinical Input
  Clinical feedback shouldn’t wait until the prototype is finished. Loop in respiratory therapists or ICU clinicians early to validate assumptions about use environment, ease of setup, or device footprint.
• Plan for Transitions
  As you move from prototype to production, your team will need to shift focus from creativity and problem-solving to process control and reliability. Start lining up partners for production, QA, and distribution during Phase IV.

Successful medical device development isn’t about staffing a large team it’s about bringing the right expertise at the right time. Early overinvestment in engineering without regulatory input, or late-stage usability feedback after tooling, can lead to avoidable rework.

Plan your resource strategy around milestones, not just timelines, and don’t hesitate to bring in temporary or fractional experts during high-stakes phases.
