The companies that consistently create market value don’t start with technology. They start with people.
During more than two decades working across engineering, commercialization, strategic partnerships, and company creation, one observation has become impossible for me to ignore.
Products rarely fail because the engineering wasn’t good enough.
More often, they struggle because the product was designed before the customer was truly understood.
I’ve watched remarkably talented teams solve incredibly difficult technical challenges, only to discover that adoption was slower than expected, differentiation wasn’t compelling enough, or customers simply didn’t change their behavior.
The engineering was exceptional.
The challenge was that engineering had been asked to optimize a product before the team had fully understood the people it was meant to serve.
That experience fundamentally changed how I think about product leadership.
I’ve come to believe that customer insight isn’t simply a commercial input—it is one of the most important engineering inputs.
The End User Belongs in Every Design Review
One sentence has stayed with me throughout my career:
The end user is one of the most important members of the engineering team—even if they never attend a design review.
Every engineering decision ultimately affects someone downstream.
The clinician.
The patient.
The manufacturing technician.
The purchasing department.
The field service engineer.
The reimbursement pathway.
The investor deciding whether to fund the next stage of development.
When product ideation begins with technology instead of these people, engineering often ends up optimizing the wrong problem.
My observation has been remarkably consistent.
Unless product ideation begins with the end user’s needs, frustrations, workflow, and desired outcomes, products often struggle to gain meaningful traction. Teams can engineer exceptional technology, but if they haven’t deeply understood who they’re helping and why it matters from the very beginning, commercialization becomes an uphill battle.
The most successful products don’t begin with a feature list.
They begin with empathy.
Engineering Creates Enterprise Value
Engineering is often viewed as the function responsible for building products.
I believe its influence is much broader.
Engineering determines manufacturing scalability.
Supply chain resilience.
Clinical workflow.
Training requirements.
Serviceability.
Regulatory complexity.
Commercial adoption.
Competitive differentiation.
Ultimately, engineering decisions create—or limit—enterprise value.
This is why commercialization should never be viewed as something that begins after engineering.
Commercial thinking belongs beside engineering from the first product discussion.
Understanding the customer isn’t the responsibility of marketing alone.
It is the responsibility of product leadership.
Design Freeze Is Often Commercial Freeze
One of the most significant milestones in product development is design freeze.
By that point, many of the decisions that determine market success have already been made.
Manufacturing cost.
Clinical workflow.
Ease of use.
Training burden.
Serviceability.
Regulatory complexity.
Scalability.
Competitive differentiation.
Marketing can communicate those decisions.
Sales can position them.
But neither can fundamentally change them.
By the time a product reaches design freeze, much of its commercial destiny has already been determined.
That is why understanding the customer must happen before engineering begins optimizing the solution.
The Companies That Change Markets Ask Different Questions
Consider what happened when Apple introduced the iPhone.
The mobile phone industry wasn’t standing still.
Companies like Nokia, Motorola, BlackBerry, Palm, and Samsung were investing heavily in better batteries, better keyboards, clearer calls, smaller devices, and improved cameras.
Apple approached the market differently.
It wasn’t engineering a better phone.
It was engineering a different role for the phone in people’s lives.
That subtle shift changed customer expectations—and ultimately redefined an industry.
The greatest competitive threat rarely comes from the company building a slightly better version of today’s product.
It comes from the company asking a fundamentally different question.
Product Leaders Engineer Outcomes
The strongest product organizations I’ve encountered don’t wait until design verification to think about the customer.
Commercial thinking is present during concept generation.
Manufacturing is present during concept generation.
Regulatory is present during concept generation.
Clinical workflow is present during concept generation.
Because every one of those perspectives influences the engineering decisions that follow.
Great product leaders understand that engineering and commercialization are not sequential activities.
They are parallel disciplines working toward the same objective:
Creating meaningful value for the people the product is intended to serve.
Practicing What We Build
These principles continue to shape every opportunity I pursue.
Whether evaluating an established product portfolio, advising leadership teams, or building ScreenHER, the first question is never,
“How can we improve the existing product?”
It’s always,
“What problem is the customer still trying to solve?”
That question changes the conversation.
Instead of protecting the current solution, teams begin designing around the desired outcome.
Everything else follows.
One Question Every Leadership Team Should Ask
Before approving the next product roadmap, I believe every leadership team should pause and ask one question:
Are we engineering a better product…
…or engineering a better future for the customer?
The answer determines far more than the next product release.
It determines whether an organization protects today’s market…
…or creates tomorrow’s.

Innovation rarely begins with the next feature.
It begins with challenging the assumptions behind the current one.
I’d love to hear your perspective.
When have you seen customer insight fundamentally change the direction of a product—or when have you seen an exceptional technology struggle because the market wasn’t understood early enough?
The best engineering doesn’t simply build products.
It creates value.
