Concept to production, under one roof
Requirements to volume manufacturing with one accountable team — none of the handoffs and vendor queues that stall a product between a design firm and a factory.
Concept to production is an engineering model in which one team carries an electronic product through every stage: requirements, system design, hardware and PCB layout, firmware, prototyping, validation, and volume manufacturing. Because nothing changes hands between design and the production line, the product reaches market faster and with fewer failed builds.
Where schedules actually go
Ask anyone who has shipped an electronic product where the schedule went, and the answer is rarely the engineering. It is the handoffs. The design firm finishes its files and moves on. The fabricator quotes, queues, and builds to print, whether or not the print was buildable. The assembler discovers the BOM carries a part with a twenty-week lead time. Each seam adds weeks, and when something fails, each party can point at the other two.
We removed the seams. Engineering and production sit in the same building, run by one team, accountable to one schedule. The stages below walk the whole path and show what changes when nobody has to hand your product to a stranger.
The path from concept to production
Seven stages, one team. Firmware starts alongside hardware, and manufacturing sees the design long before it is frozen.
- 01
Requirements & system design
We turn the idea into written requirements and success criteria, then choose the architecture: processor, connectivity, power, sensing. Feasibility questions get answered on paper, where changing the answer costs nothing.
- 02
Hardware & PCB design
Schematic capture, component selection against real market availability, and board layout. Because the production floor is in the same building, design-for-manufacturing review happens while the layout is still cheap to change.
- 03
Firmware & embedded software
Firmware is written alongside the hardware rather than after it. Board bring-up code, drivers, and application logic are ready when the first prototypes arrive, so integration starts the week the boards do.
- 04
System integration
Hardware, firmware, and the enclosure come together as one product for the first time. Interfaces, power behavior, and mechanical fit are exercised as a whole, and the issues that only appear at the seams get found here.
- 05
Prototype & EVT
The first real boards are built and brought up. Engineering validation testing (EVT) proves the design works: core functions verified, major risks retired, and the changes that every first build produces are folded back in.
- 06
DVT & compliance
Design validation testing (DVT) runs production-intent units against every requirement, including environmental stress and EMC pre-compliance. The design freezes only when it has earned it.
- 07
NPI & production ramp
New product introduction moves the frozen design onto production tooling. A pilot run (PVT) proves yield, assembly, and test repeatability, and then the same line that built the pilot builds your volume.
EVT vs DVT vs PVT: the three validation milestones
Before a product ships in volume it passes three build-and-test gates. EVT proves the design works, DVT proves it meets every requirement, and PVT proves it can be built repeatably on a production line. Each gate uses more mature hardware and tighter acceptance criteria than the one before it.
| EVT — Engineering Validation | DVT — Design Validation | PVT — Production Validation | |
|---|---|---|---|
| Core question | Does the design work at all? | Does it meet every requirement? | Can we build it repeatably at volume? |
| Build quantity | A handful of prototypes | Tens of near-final units | A pilot production run |
| Hardware maturity | First working boards, often hand-built | Production-intent design and parts | Final design on production tooling |
| Primary focus | Core functionality and major design risks | Full spec, environmental, and regulatory compliance | Yield, assembly, test, and process repeatability |
| Exit criteria | Functions verified, major issues fixed | Design frozen, all requirements met | Process qualified, ready for mass production |
What one roof changes
Design-and-build is a set of mechanical advantages that show up in the schedule and the budget.
DFM before release, not after failure
Design-for-manufacturing review happens while the layout is still open in the CAD tool. Panelization, test access, and assembly tolerances get decided by the people who will run the build.
Iteration in days
A prototype change is a conversation and a short build, not a purchase order and a vendor queue.
One owner for root cause
When a build issue appears, there is no fab-versus-designer standoff. The same team owns the design and the process, so problems get fixed instead of litigated.
No re-qualification at scale
The line that runs your PVT pilot is the line that builds your volume. Scaling up never means introducing a new manufacturer to your design.
Why this is cheaper and faster
There is no magic in it. Every handoff you remove takes its queue time, its re-quoting, and its misunderstandings out of the project. Design decisions get made with production cost in view, so the expensive surprises (an unbuildable footprint, a part that cannot be sourced, a board that fails in assembly) are caught on a screen instead of on a line. And because validation builds run where the design was made, each EVT and DVT cycle turns around in days rather than shipping cycles.
We will not put a percentage on it, because the true number depends on your product. What we can say is where the savings come from, and every one of them is structural.
The disciplines inside the lifecycle

Concept-to-production FAQs
In seven stages: define requirements and system architecture, design the hardware and PCB, develop the firmware, integrate everything into a working system, validate prototypes through EVT, freeze the design through DVT and compliance testing, and ramp production through NPI and a pilot build. At AEE all seven happen with one team, and the last one happens on our own floor.
They are the three build-and-test milestones before mass production. EVT (engineering validation test) proves the design works. DVT (design validation test) confirms it meets every requirement, including environmental and regulatory ones. PVT (production validation test) verifies the product can be built repeatably at volume on production tooling.
DFM is the practice of designing a product so it can be built affordably and reliably, not just so it works on the bench. It covers component availability, assembly tolerances, panelization, and test access. Skipping it is how designs pass the prototype stage and then fail on a production line.
One vendor takes responsibility for the entire product: design, prototyping, validation, and manufacturing. You bring requirements and receive finished, tested units.
NPI is the transition from a frozen design to repeatable production: tooling, assembly documentation, test fixtures, operator training, and a pilot run that proves yield before volume commitments are made.
The design is yours either way. We release complete fabrication and assembly packages in standard formats, so any competent manufacturer can build from them. Most clients stay because the team that designed the product already knows how to build it, but that is a choice, not a condition.
