What Does "Finishing" Mean in R&D: The Road from Prototype to Manufacturable Product
March 13, 2026 • 5 Min Read
Many good ideas remain stuck at the working prototype stage. Because there is a significant "finishing" gap between designing something and transforming that design into a testable, manufacturable, and sustainable technology product.
The 90/10 Rule: The Hardest Part Is the Last 10%
There is a famous saying in the engineering world: "90% of the work takes 10% of the time, and the remaining 10% takes 90% of the time." Getting a prototype to work is exciting — but making that prototype run smoothly on a serial production line requires real "finishing."
At MECRONIC, we approach every project with this "last 10%" perspective from the very start. We track every detail — from the material supply chain to assembly ease — until the product rolls off the line.
"Real engineering is not just making something that works; it is making something that keeps working and can be manufactured."
The Keys to Finishing
- Documentation: Unwritten code and undrawn schematics mean unfinished work.
- Test Scenarios: Passing not just normal conditions but also the most demanding scenarios on paper.
- Manufacturability (DFM): Aligning the design with manufacturing constraints.
Ultimately, finishing is an obsession with detail and the determination not to leave a project on the desk. Our partners know: if a project comes to MECRONIC, it will end up in the field — not on a shelf.
