A print doesn’t tell the whole story.
It shows dimensions, tolerances, and specifications. But it doesn’t always communicate how a device is used, what truly drives performance, or where risk is hiding beneath the surface.
That’s where the pre-production meeting (PPM) becomes one of the most important moments in the entire product lifecycle.
For implantable medical devices, a strong PPM isn’t a formality. It’s the difference between a smooth path to production and a cycle of revisions, delays, and unnecessary cost.
At Lowell, we treat the PPM as the point where design intent becomes manufacturing reality.
Why Pre-Production Meetings Matter More Than Ever
Medical device development is under constant pressure.
Tighter tolerances. Faster timelines. Increasing regulatory expectations.
Design teams are expected to get it right early, often with limited iteration. But without alignment between engineering, manufacturing, and quality, even the best designs can stall.
That’s why leading manufacturers don’t wait until production to solve problems. They surface them upfront.
A well-structured PPM creates:
- Shared understanding of design intent
- Early identification of manufacturability risks
- Alignment on inspection, validation, and documentation
- Clear ownership across teams
It’s not just a meeting. It’s a risk reduction strategy.
What a Strong PPM Actually Covers
At Lowell, our pre-production meetings follow a structured framework designed to eliminate ambiguity and accelerate progress. While every program is different, the core areas of focus remain consistent.
Here’s what that looks like in practice:
Design Requirements and Intent
Before anything is machined, everyone needs to understand one thing:
What truly matters for this device to function as intended?
This includes:
- Reviewing whether design requirements are complete
- Discussing DFM (Design for Manufacturability) opportunities
- Aligning on functionality and real-world use
As highlighted in Lowell’s design intent strategy, these discussions are most effective at the very beginning of a project, where clarity can prevent downstream delays.
This is where engineering teams explain how the device works, how components interact, and what cannot be compromised.
Because not every dimension is equal, and treating them that way creates unnecessary complexity.
Drawings, Models, and Specifications
A strong PPM ensures that all technical documentation is aligned and usable across teams.
This includes:
- Final drawings and 3D models
- Model and document transfer processes
- GD&T interpretation
- Specifications for materials, finishes, and packaging
- Marking requirements (UDI, CE, etc.)
Our checklist reinforces this step clearly, ensuring nothing is assumed and everything is verified before production begins .
At this stage, clarity is everything. Misalignment here leads directly to rework later.
Inspection and Quality Requirements
Precision doesn’t stop at machining. It must be proven.
A strong PPM defines:
- First Article Inspection Expectations
- Sampling plans (e.g., AQL standards)
- Measurement methods and gauge strategy
- Validation requirements
- Certification needs (material, compliance, analysis)
Our checklist outlines these elements explicitly, reinforcing that inspection planning is not an afterthought; it’s part of the production strategy from day one .
When these requirements are aligned early, validation becomes faster, cleaner, and more defensible.
Supply Chain, Timeline, and Logistics Alignment
Even the most precise component fails if it arrives late or incomplete.
That’s why a strong PPM also addresses:
- Supply and quality agreements, when applicable
- Project timelines and milestones
- Shipping locations and requirements
- Customer-specific documentation needs
These operational details, captured in our checklist, ensure that execution matches expectation across every stage of production.
Communication Structure and Accountability
One of the most overlooked elements of a PPM is also one of the most critical:
Who owns what?
Our checklist formalizes this by identifying:
- Key contacts across engineering, quality, supply chain, and customer teams
- Clear communication pathways
- Defined points of escalation
This aligns directly with Lowell’s project management philosophy, strong communication and defined ownership are essential to reducing delays and keeping projects on track.
When questions arise, speed matters. And speed comes from clarity.
What Separates a Good PPM from a Great One
Many companies hold pre-production meetings.
Fewer use them to their full potential.
The difference comes down to mindset.
A good PPM reviews the print.
A great PPM challenges it.
It’s where:
- Manufacturers provide DFM insights based on real production experience
- Engineers validate assumptions about function and performance
- Teams collaborate in real time to remove unnecessary steps or risks
As Lowell’s design intent work shows, these conversations can lead to meaningful improvements, even eliminating entire process steps when data and experience support it .
This is where partnership shows up.
From Alignment to Acceleration
When done right, a PPM does more than align teams. It accelerates outcomes.
It reduces:
- Iteration cycles
- Miscommunication between teams
- Validation delays
- Risk of nonconformance
And it increases:
- Confidence in the manufacturing process
- Speed to qualification
- Overall project predictability
At Lowell, this approach is embedded into our New Product Introduction (NPI) process, where cross-functional teams meet regularly to ensure alignment from kickoff through production.
The Lowell Difference
For us, a pre-production meeting isn’t a checklist exercise.
It’s a commitment to getting it right before it starts; because in implantable medical device manufacturing, success isn’t defined by how quickly you can fix problems.
It’s defined by how effectively you prevent them.
