We enjoy working with quality clients on quality projects because we are motivated to deliver our best work and always excited for more.

We are requirements-driven such that we can offer an accurate estimate of work and use them to drive your project towards success as defined by you.

25 years of start-up and business experience in the aerospace, electric-vehicle, petrol-chemical, service-industry, semiconductor and medical industries enables us to deliver on time and within budget.

Development Costs | Traditional vs. Lean

Our previous article, “Lean & Affordable Product Development” revealed our approach that doesn’t require big budgets because our focus is to solve the functional problem first with a reference for the desired aesthetic employing DFM, rapid iterations, and economic manufacturing techniques. The approach is sensible and efficient regardless of budget size. Let’s take a deep dive into one of our latest projects to reveal the “Tale of Woe” so many entrepreneurs, inventors, and start-ups learn the hard way when following traditional industrial design product development.

The Stealth Consumer Product Example

The image above is the rendering of the product in its market testing form and is a real-world classic example. It is a complex product. It has a control board, power inverter board, electromagnetic piston, a capacitive sensor, and more that all have to be developed in parallel and packaged together in a tight, sexy, and IP66 waterproof case.

The cost to dress-up and make a solution super sexy is far less than the cost to engineer a high performing solution with a low BOM cost. Our lean and affordable product development saved the client from having to abandon his idea due to outrageous development costs if he pursued it the traditional way (form before function).

This is how it would have played out if we followed the traditional industrial design path:

Conceptual Phase $20-25k

Develop a sexy and miniature concept per client’s vision with sketches, 3D models, renderings with synced branding and imagery in target markets, iterate until the client is happy.

Design & Engineering Phase $20-25k

Attempt to design and engineer the internal components, control boards, etc. to fit the concept, test, and achieve performance requirements. Will require full-blown miniaturization upfront and the development of custom PCBs and more.

Re-design & Re-Engineer Phase $20-25k

Failure of step two actualizes when learning a few of the original assumptions were wrong, various internal components had to change in size and function to achieve the functional and performance requirements.  Now, it is a total struggle to keep the same sexy form, incurring significant extra design work “editing” the original to evolve the form with the evolution of the function of the internal components in tandem.

More Redesign $25-35k

Learn more changes are needed for a myriad of factors from additional testing, can’t use additive manufacturing anymore for performance testing due to the need for homogenous materials, re-design for CNC machining, build more prototypes finally make it functional with a very different looking product than the one presented in step 1.

Market Testing

Try to market test, but it costs so much to make the entire assembly and the client used all of his money in the first 4 steps and is stuck trying to convince an investor to give $100k+ to market test an unproven product concept (in the market) and the design is too expensive to make anyway.


We are not dream-crushers here, we are dream-makers and this is how it really went down:

Feasibility Study $1.5k

Identified client’s assumptions are incorrect, heart-to-heart reality check.

Design & Engineering Phase $3.5k

Pursue two simple functional design concepts, prototype, test, verify, walk away with a functional path.

Performance Testing Phase $7k

Develop internal components in parallel with the step above using OTS (Off The Shelf) control boards (Think Arduino, Beetle Boards, etc). A custom Power Inverter board was made. Test and Iterate twice to meet performance requirements.

Design for Pre-Production $3.5k

Design product assembly, packaging with visual for market testing, and using CNC machining for the case while the internal components are still OTS with the one custom power board.

Market Testing - $5k

Build 20 assemblies for market testing. $5k


There is a DFM manufacturing theme throughout our website for a reason. We want potential customers and clients to understand that they can have an economic and lead-time advantage working with a team that spent a large portion of their careers on the shop floor and therefore can guide them along the most efficient and cost-effective path.

So why are most firms and universities using/teaching the traditional industrial design process one may ask? It’s two-fold. First and foremost, they never put their own net-worth on the line to develop their own idea or as a business owner.  If they had, they would have learned the economic lessons the hard way at the expense of their well-being.

Second, they have very little experience in the myriad of manufacturing disciplines. Start-ups and inventions are not imagined from the manufacturing shop floor. They never made parts with CNC machines, never ran a sheet metal press, never operated a wire EDM, never polished 10,000 small caps by hand to understand the cost, time, and just how dangerous optimistic BOM costs are.


While Ryan T. worked at Tesla Motors (employee #24), all the different powertrain groups struggled to meet deadlines and objectives for their respective technologies throughout the development of the Tesla Roadster. Ryan T’s battery enclosure struggled much less and hit most of the targets because he took a requirements-driven approach when the other groups did not. Constantly preaching to his mentor Dave Lyons to require the other groups to do the same, it never transpired and it was a struggle to the end (production).

However, guess what was implemented for the next vehicle program called, “Whitestar”?  You guessed it.  A dozen system engineers were hired and a full-blown systems/requirements-driven strategy was implemented from the very beginning for that next vehicle, which became the infamous Model S and the automobile of the year; arguably one of the greatest automobile in history.

Dave told Ryan, “You were right man, I never want to go through that again and we are going full-blown requirements-driven all the way!”

Our design, build, learn mantra comes from Dave who was the director of Engineering at Tesla. Prior, he was also the Program Manager at IDEO for 13 yrs beforehand.  IDEO is a global leader and one of the most revered design firms in the engineering and design community.

Lastly, the requirements-driven development philosophy stems from an earlier mentor Bill Brooks. He was the director of engineering for NASA for over 20 years and Ryan T. adopted it ever since working with him at inTest.


We will listen and work hard to build your vision.
