How Do You Develop a Product? The Stages That Helped Us Bring Hundreds of Ideas to Market
A complete walkthrough of the ATI product development process - from idea conversation to mass production.
In Brief
Over close to 30 years and hundreds of projects, ATI has refined a development process that takes an idea from a first conversation to mass production. This article walks through the major stages so first-time entrepreneurs know what to expect.
Stage 1: Feasibility Conversation
Before any contract, we hold an open conversation about the idea, the entrepreneur's background, the target market, and the budget. Not every idea is right for development - sometimes the market isn't ready, the technology is too immature, or the budget is too thin to reach production. Saying so up front is part of our job.
Stage 2: Characterization (PRD)
Once we move forward, we write a Product Requirements Document. The PRD captures functionality, materials, mechanics, electronics, certifications, packaging, and a target unit cost. It becomes the source of truth that guides every later decision.
Stage 3: Industrial Design
Industrial designers turn the PRD into form: ergonomics, user experience, look and feel. Sketches and renderings are reviewed with the entrepreneur until the visual direction is locked.
Stage 4: Mechanical and Electronic Engineering
Engineers turn the design into a manufacturable product: 3D CAD, mechanism design, PCB design, firmware. This is where most surprises happen, and where ATI's experience earns its keep - we anticipate manufacturing constraints early so the product is buildable.
Stage 5: Prototyping
Functional prototypes (3D-printed, CNC-machined, or vacuum-cast) validate the design in the real world. Most products go through 2-4 prototype rounds before tooling.
Stage 6: Tooling and Pilot Run
Once the design is locked, we cut steel - injection molds, sheet metal dies, fixtures. The first pilot batch comes off these tools and is tested end-to-end against the spec.
Stage 7: Mass Production
With the pilot validated, we scale up. Independent QC, ongoing factory management, and continuous improvement all sit on top of mass production.
Tip From the Experts
The biggest single predictor of project success isn't the idea - it's the rigor of the characterization stage. Entrepreneurs who invest in a thorough PRD almost always end up with a better product, in less time, at lower cost.
Key Takeaways
Feasibility First

PRD Is Source of Truth
Specification drives every later decision.
Design + Engineering
Form, function, and manufacturability together.
Iterative Prototyping
Two to four prototype rounds before tooling.
Tooling and Pilot
Pilot batch validates the production tools.
QC at Scale
Independent inspection during mass production.
Frequently Asked Questions
How long does the full process take?
Typical range is 8-18 months from kickoff to mass production. Complex regulated products can take longer.
How much does it cost?
Highly product-dependent. We provide a clear scope and budget after the feasibility conversation.
Do I need a patent before starting?
Not necessarily. A provisional patent can be filed early to lock in priority while development continues.
Can I change the spec mid-project?
Yes, but every change has a cost. We surface implications transparently so decisions are informed.
Do I need to manufacture in China?
Most consumer products benefit from China manufacturing. Some categories are better served locally.
Who owns the IP?
You do. Our customer agreements transfer all IP to the customer.
