Product Strategy & Definition

Product strategy for complex hardware before the wrong decisions get expensive

In complex hardware development, you can spend months building on a decision that was wrong from the start. Assumptions about product architecture, user needs, regulatory requirements or manufacturing can shape an entire development program before anyone realizes there’s a problem.

By then, significant time and money may have been committed. What could have been a simple course correction becomes costly rework, regulatory delays or a fundamental rethink of the product.

We help teams make the right decisions in the right sequence, while there’s still room to change course. By bringing together technical, user, regulatory, market and manufacturing expertise early, we help establish what can move forward and what still needs to be proven.

The order of decisions can change the outcome of your product.

Some decisions can wait. Others shape everything that follows. Knowing which questions to answer first can prevent months of wasted development and costly rework.

The challenge isn’t a shortage of decisions. It’s knowing which ones to make first.

Product architecture, user requirements, regulatory pathways and manufacturing decisions are interconnected. A choice made in one area can create constraints in another.

Good product strategy helps teams understand those dependencies, identify what needs to be proven, and make informed commitments in the right order.

Good product strategy establishes what needs to be decided, what needs to be proven, and what can wait.Inertia’s Product Strategy Sprint brings the right expertise together to resolve the questions that matter most before the next major development commitment.

Product Strategy Sprint

Inertia’s Product Strategy Sprint is a senior-led engagement that brings together engineering, user, regulatory, market and manufacturing expertise to resolve the questions shaping your product’s next stage of development.

When teams bring us in

Teams bring us in when an important product decision needs more evidence, expertise or validation before they can confidently move forward.

Here are some of the situations we see most often.

You need to understand the regulatory, reimbursement or market path for a medical device.

You may have a promising medical device or diagnostic concept, but regulatory classification, intended use, reimbursement, evidence requirements, market access or adoption assumptions are still shaping what the product can realistically become. These are not side considerations to add later. They can change the product definition, development plan, evidence strategy, architecture, workflow, commercialization path and the investment required.

You need a physical prototype to resolve a critical technical challenge.

A prototype built for this purpose is deliberately focused on the question that matters most. It might isolate a mechanism, interface, sensing approach, thermal problem, fluidic issue, form-factor constraint, workflow interaction or architectural assumption. The goal is not to build a miniature finished product. It is to learn enough from real hardware to make the next product decision with confidence.

You are defining the first version of a platform.

Several credible versions may be possible, but the team cannot fund all of them at once. The work is to determine what belongs in the first product, what can wait, what needs evidence now, and what has to be true before further commitment makes sense.

You already have a product in development and another major commitment is approaching.

Engineering has momentum, but another substantial round of development, capital, tooling, validation or program commitment is coming. The team needs to know whether the current direction still holds, what has changed, and what needs to be resolved before more is committed.

You have a promising technology, but the product around it is still taking shape.

The technical capability may be real, but the strongest product, user, workflow, market and business case around it may still be undefined. The work is to determine where the technology creates enough value to support a viable product.

You are deciding what comes next.

The current product may already be in market, or several next-generation directions may be competing for investment. The team needs to decide which product, market or platform direction deserves the next serious commitment.

What the Product Strategy Sprint covers

Each Sprint draws on the expertise your product needs, bringing together senior specialists across engineering, user research, regulatory strategy, market access and manufacturing.

We examine the product through three connected areas: People & Use, Market & Access, and Feasibility & Cost. Together, they help establish whether people will use it, whether the business can work, and whether the product can be built at a viable cost.

Feasibility & Cost

Can we actually build it, at a cost that works?

Understand the technical architecture, development and manufacturing realities, and cost assumptions that determine what can actually be built.
Areas of work
- Architecture Selection & Technical Risk Assessment
  Compare candidate architectures and identify the risks most likely to block progress.
- Proof-of-Concept Prototyping
  Build the smallest prototype that answers the biggest unknown, including proof-of-physics work where needed.
- Should-Cost & Design-to-Cost Analysis
  Estimate what the product should cost to make and compare that against the target cost.
See how we shape what can actually be built
People & Use

Will people want it, choose it and use it?

Understand the users, workflows, unmet needs and adoption realities that determine whether the product earns a place in the real world.
Areas of work
- Stakeholder & Use-Environment Mapping
  Who uses it, who decides, who pays, and where it gets used.
- Voice of Customer & Workflow Discovery
  Watching and interviewing real users, then mapping how the work gets done, step by step.
- User Needs & Requirements
  A ranked view of what users need, where the product could fail in use, and the requirements engineers can build to.
See how we uncover what users actually need
Market & Access

Can it support a viable, scalable business?

Understand who buys, how the product gets paid for, and the market, regulatory and access realities that determine whether the business works.
Areas of work
- Reimbursement & Procurement Landscape
  Who pays, by what route, and who signs off. Include medical-device reimbursement and procurement realities where relevant.
- Regulatory & Standards Strategy
  The approvals, standards and evidence expectations that need to be understood early enough to shape the product.
- Market Sizing & Competitive Landscape
  A grounded view of the reachable market and the alternatives buyers use today.
See how we determine what makes the business viable

What a Product Strategy Sprint produces

Every Sprint is shaped around the decisions your team needs to make. The work and deliverables depend on the questions we’re trying to answer.

Depending on your needs, a Sprint may produce one or several of the following outcomes.

Medical device regulatory, reimbursement and market access strategy

A practical path through the external requirements that will shape the device, the evidence program and the route to market.

Regulatory pathway. FDA, Health Canada, EU MDR / IVDR, intended use, likely classification, submission pathway and the evidence expectations that may affect product definition.
Reimbursement and market access. Payment, purchasing, coding, coverage and adoption realities that can materially change the commercial path.
What needs to be decided now. Which regulatory and market-access questions need to influence the product today, and which can wait until later development.

Medical device product definition and requirements baseline

A documented starting point for the device before detailed development moves ahead.

Intended use and product scope. What the device is, who it is for, where it will be used and what belongs in the first product.
User needs and design inputs. The needs, functional requirements, performance expectations and constraints that are ready to start carrying into development.
Early risk and regulatory foundations. The product assumptions, use-related risks, safety considerations and documentation that will eventually need to stand up within the design-control process.

Technical prototype

A focused piece of working hardware built to answer a specific technical question before the team commits to a more complete product.

Proves what needs proving. That could be a mechanism, sensor, fluidic path, thermal architecture, electronics approach, interface or other critical part of the system.
Built around the question, not appearances. It does not need to look like the finished product. It needs to generate useful evidence.
Especially valuable when hardware is the unknown. For a medical device, that might mean proving a sample-handling approach, sensing method, mechanical interaction or critical subsystem before more development is committed.

User and workflow evidence

Evidence about who the product is for, how it needs to work in the real world, and where current assumptions need to change.

User needs and priorities. What users actually need from the product and which needs matter most to adoption and use.
Real workflow fit. How the product sits within the physical, clinical, industrial or operational environment in which it will actually be used.
Evidence that changes the product. Findings that can influence requirements, usability, architecture, interfaces or the next round of development.

Manufacturing feasibility and cost plan

An early manufacturing view of how the product could be built, what will drive cost, and which production decisions need to influence development now.

Manufacturing approach. Likely processes, assembly methods, materials and production constraints that should inform the product architecture before it hardens.
Cost and volume assumptions. Early BOM, tooling, labor, volume and COGS ranges that help determine whether the product and business case can work together.
Sourcing and production risks. Critical components, supplier dependencies, long-lead items, tolerances and other manufacturing issues worth addressing before detailed development goes too far.

Decision record for development and manufacturing

A documented record of the important product decisions, evidence, assumptions and constraints that later teams need to inherit.

What was decided and why. The reasoning and evidence behind important product choices are captured instead of being left in meeting notes or people’s heads.
What is still assumed. Open assumptions and uncertainties remain visible so later teams know what may need to be revisited.
What needs to carry forward. Development and manufacturing teams inherit the context behind the product instead of having to reconstruct it later.

Ready to work through the decisions holding your program back?

Bring us the product, the evidence you have, and the questions that still need answers. We’ll help determine where the Sprint should focus and what needs to happen next.

Featured Product Strategy Case Study

Point-of-care diagnostics

Point-of-care blood analyzer

A cartridge-based, single-drop biomarker analysis platform for decentralized testing, built on integrated electrochemistry and precision mechanical interfaces.

Challenge

A decade of proven electrochemistry lived as disconnected prototypes, with sensing, firmware, cartridge, and enclosure, but no architecture tying them into a manufacturable product.

Approach

Architecture first. We aligned electrochemistry, cartridge interface, firmware, and mechanics on a single alpha platform, and pivoted from multi-user to single-user to cut contamination and interface complexity.

Outcome

A fully integrated diagnostic platform, structured for regulatory and V&V pathways, carrying Verv from fragmented R&D to a coherent, manufacturable device.

"Having worked with several engineering firms over the years, Inertia truly stood out. They were the only team that consistently delivered exactly what we expected: organized, proactive, and always moving forward. Their exceptional communication and project management, with regular, in-depth updates, were especially reassuring given our significant investment.
Unlike other firms, who lacked oversight and attention to detail, Inertia excelled in every aspect, from project management to design controls. Their talented team delivered a diagnostic device platform that exceeded our expectations. Without a doubt, they are our top recommendation. No one else comes close."

Jeff SuttonVerv Technologies

"Inertia brings creative design, thoughtful engineering, and a sensitivity to scaled manufacturing, along with proactive thinking around potential roadblocks. I haven't contracted a firm with the same scope as Inertia before. Other vendors have had much more specific areas of focus for support. With those vendors, I've had to be much more hands-on in terms of providing instruction on wants and needs, and it's been more stressful overall since aspects can go wrong if I'm not micromanaging.
With Inertia, I don't have any of those concerns. It's been a great collaborative process with clear communication, and the team at Inertia really understands what we're building, like they're part of our company. It's been a pleasure working with Inertia so far and we hope to have many more years of successful collaboration ahead."

Eric KriegsteinChief Executive Officer, Infusense

"Working with Inertia is a very positive experience. We are developing a new analytical device in an environment where the path is still evolving and the work requires flexibility and sound product development judgment. What has stood out is the way the Inertia team has embraced that reality: they listen carefully, adapt as the project changes, and help us keep moving without forcing the work into a rigid process.
Even when issues came up, the team responded constructively and improved the way we worked together. Their capacity of combining technical capability, responsiveness, patience in due time, and genuine collaboration is very valuable, and I would recommend Inertia without hesitation."

Veronique BougieChief Operating Officer, Anasens

"What stands out with Inertia is that they do not wait. They come into a meeting having already found the problem, gone to the root cause, and put it on paper: this is why, this is the consequence, these are the options, and this is the one we recommend. Usually in R&D someone tells you there is a problem and it is yours to work out. Here the solution arrives with it.
Everything around the work is just as organized. The presentations are well structured, bullet points come after every meeting so nobody gets lost in who said what, and the action items are always clear. Having worked with other engineering teams in different contexts, Inertia stands out as extremely rigorous, both in documenting the thinking behind a decision and in knowing medical devices and manufacturing properly.
For us the value is the quality. The team is autonomous, they get the product, and we have never had to micromanage. We trust their expertise."

"Being a first-time entrepreneur, the Inertia team fully immersed me in their product development experience and made me feel in total control of my product’s destiny, providing exceptional support required to get the work done right and on time.
They shared with me all their knowledge and understanding of the technical, regulatory, and commercial landscape which empowered me to make the best decisions for my product and my customers. Their transparency, communication, and collaboration are head and shoulders above anything I've ever experienced."

Dayo Olakulehin MDChief Executive Officer, Ligand Innovation Global

"What differentiated Inertia was the combination of structure, ownership, and consistent follow-through throughout the project. The team moved the work forward steadily and independently, without requiring much day-to-day oversight from our side. There was clear progress from week to week, and it felt like dedicated resources were actively advancing the work between meetings rather than waiting for the next check-in to determine what to do next.
The team brought strong communication, thoughtful listening, and creative problem solving to the work. Feedback was taken seriously, ideas were translated into practical next steps, and the overall experience felt smooth and productive.
Inertia came across as a capable, well-organized development partner that could take ownership of a defined scope, maintain momentum, and deliver quality work with a high degree of autonomy."

Product strategy and definition questions, answered

What is product strategy for hardware development?

Product strategy establishes what you’re building, who it’s for, whether it can succeed commercially, and what needs to be proven before committing to development. For complex hardware, that means evaluating user needs, technical feasibility, regulatory requirements, market opportunities, and manufacturing costs together.

When should a company invest in product strategy?

Product strategy is most valuable before major development commitments, but it can also help when an existing program encounters uncertainty. Teams often need support when defining a new product, evaluating a technology, choosing a regulatory pathway, resolving a technical challenge, or preparing for their next stage of investment.

What happens during Inertia’s Product Strategy Sprint?

Inertia’s Product Strategy Sprint is a senior-led engagement focused on the decisions that matter most to your product. Depending on the challenge, the work may include user research, technical investigations, physical prototyping, regulatory and reimbursement strategy, market assessment, or manufacturing feasibility. The scope is shaped around the questions your team needs answered.

What will our team have at the end of a Product Strategy Sprint?

Deliverables depend on the work undertaken. They may include a technical proof-of-concept prototype, a regulatory and market roadmap, documented user needs and product requirements, manufacturing cost assessments, or a record of key decisions, assumptions, and supporting evidence. The goal is to give your team something concrete to carry into the next stage of development.

Can Inertia help validate a technology or build an early prototype?

Yes. Inertia’s engineering and prototyping teams can investigate specific technical risks, conduct experiments, and build physical prototypes to test critical assumptions. These are often focused technical demonstrations rather than finished product prototypes. The objective is to establish whether a proposed approach is feasible before committing to more extensive development.

How does product strategy address regulatory requirements and manufacturing feasibility?

For medical devices, regulatory requirements and reimbursement considerations can influence product architecture, intended use, and market strategy from the beginning. Manufacturing considerations can be equally consequential across complex hardware categories. Inertia brings these perspectives into early product decisions, drawing on specialist regulatory expertise where required and its own development and manufacturing experience.

How is a Product Strategy Sprint different from starting a traditional product development project?

A traditional product development project typically begins with an agreed direction and focuses on designing, engineering, and delivering the product. A Product Strategy Sprint helps establish whether that direction is sound before making larger commitments. It focuses on resolving critical questions, testing assumptions, and identifying the decisions that should guide development. The Sprint can also help teams already in development work through challenges that require a change in direction.
