The Roadmap: Key Phases in the Prototype-to-Production Journey
To successfully scale a product, understanding the key phases between prototype and production is essential. We guide you through a structured four-phase approach that ensures your product is production-ready.
LLWL: Creating a Looks-Like, Works-Like Prototype
The first milestone in scaling your product is creating a Looks-Like, Works-Like (LLWL) prototype. This prototype closely resembles the final product in both design and functionality, allowing you to test and refine the product before moving to manufacturing. Typically, 1-5 units are produced in this phase.
EVT: Engineering Verification Testing
During the Engineering Verification Testing (EVT) phase, we produce 20-50 units using low-volume manufacturing techniques. Rigorous testing verifies that the product meets all defined engineering specifications, including functional, durability, environmental, and preliminary compliance testing.
DVT: Design Verification Testing
The Design Verification Testing (DVT) phase focuses on manufacturability at scale with 100-250 units. We verify that components fit correctly, production processes are efficient, and the product meets all safety and regulatory requirements.
PVT: Production Verification Testing
In the Production Verification Testing (PVT) phase, we produce 500-1000 units to validate the entire production line, packaging, logistics, and quality control processes. This phase ensures that all processes are ready for full-scale manufacturing.
Each phase involves progressively larger production runs, allowing for the identification and resolution of issues before significant investment in tooling and inventory occurs. This structured approach ensures a smooth transition from prototype to production.
| Phase | Units Produced | Testing Focus |
|---|---|---|
| LLWL | 1-5 | Design and Functionality |
| EVT | 20-50 | Engineering Specifications |
| DVT | 100-250 | Manufacturability and Safety |
| PVT | 500-1000 | Production Line Validation |
Design for Manufacturing (DFM): Optimizing Your Prototype for Production
The journey from a prototype to a production-ready design hinges on the effective application of Design for Manufacturing (DFM). DFM is about designing with the realities of manufacturing in mind, considering factors like material selection, ease of assembly, and the limitations of manufacturing processes.
Simplifying Designs for Manufacturability
Simplifying designs for manufacturability involves reducing part counts, eliminating unnecessary complexity, and ensuring that assembly processes are straightforward and repeatable in a production environment. By doing so, we can significantly reduce production costs and improve product quality.
- Reduce part counts to minimize assembly time and costs.
- Eliminate unnecessary complexity to improve manufacturability.
- Ensure assembly processes are repeatable and efficient.
Material Selection Considerations for Scale
Material selection becomes critical when scaling to production. Materials that worked well for prototyping may be too expensive, difficult to source, or incompatible with high-volume manufacturing processes. We guide you through evaluating each component with DFM principles in mind.
Reducing Complexity and Production Bottlenecks
Understanding manufacturing process limitations is crucial. Features that are easily created through CNC machining or 3D printing may require significant redesign for injection molding, stamping, or other mass production techniques. By implementing DFM early in the design phase, we can reduce production costs, improve quality consistency, and accelerate time-to-market.
By applying DFM principles, we can identify potential production bottlenecks before they become costly problems during manufacturing, ensuring a smoother transition from prototype to production.
Transitioning from a Prototype to a Production-Ready Design: Best Practices
Successfully transitioning from a prototype to a production-ready design is crucial for product success and involves several key best practices. As we navigate the complexities of scaling up production, it’s essential to adopt a proactive approach that considers manufacturing processes from the outset.
