After working on over 1,000 product development projects for more than 275 small businesses, we’ve seen a common issue time and again—companies working incredibly hard to develop the wrong product. It’s like designing a motor controller with a perfect PWM (Pulse Width Modulation) signal but for the wrong voltage range. No matter how refined the execution is, if the fundamental concept or conceptual design is flawed, the entire effort is wasted.
This is where Conceptual Design plays a crucial role. It sets 90% of the development cost, unit cost, performance, usability, and overall success of a product. If you get this phase wrong, everything afterwards—from prototyping to Design Verification Testing (DVT)—can turn into an expensive lesson in failure.
So, what makes a strong Conceptual Design, and how can you ensure that you’re setting the right foundation for your product? Let’s break it down.
Understanding Conceptual Design: More Than a Block Diagram
Many engineers and product developers mistake Conceptual Design for a simple block diagram or system flowchart. But just as a motor controller isn’t only about setting up an H-bridge, Conceptual Design isn’t just about defining components. It’s about deeply understanding the requirements and comparing different approaches to find the best possible solution.
Consider Apple’s iPod. At the time, digital music players were already on the market, but Apple recognized that ease of loading songs was a crucial requirement. This led to the creation of iTunes, an ecosystem that made transferring music seamlessly. If Apple had skipped the Conceptual Design phase and jumped straight into building another MP3 player without this insight, history might have played out very differently.
Laying the Groundwork for a Strong Conceptual Design
To develop a product with a solid foundation, follow these key steps:
Without well-documented requirements, a Conceptual Design is just guesswork. Imagine trying to design a motor controller without specifying torque requirements, efficiency targets, or operating temperatures. You might end up with something that spins a motor but doesn’t meet the actual needs of the application.
- Keep requirements solution-agnostic—avoid phrases like “must use a BLDC motor” and instead state “must achieve X RPM with Y efficiency.”
- Prioritize requirements based on impact and feasibility.

2. Widen Your Input Sources
Great Conceptual Design doesn’t happen in isolation. In motor control, input from firmware engineers, mechanical designers, and power electronics specialists can optimize the system. Likewise, in product development, insights from diverse teams can uncover critical factors you might miss.
Include perspectives from:
- Customers and end-users
- Vendors and suppliers
- Industry experts
- External product development consultants
Broadening your team ensures you don’t overlook valuable insights that could lead to a better design.
3. Allocate Adequate Time
One of the biggest mistakes companies make is rushing Conceptual Design to jump into detailed development. This is like tuning a PID controller without first understanding the motor dynamics—it leads to instability and inefficiency.
- Small businesses often have long product life cycles, meaning they can afford to take time in this phase.
- Most development costs come later in detailed design and Design Verification Testing (DVT), so a well-executed Conceptual Design can reduce costly iterations.
- Regularly revisiting and refreshing Conceptual Designs can prevent disruptive surprises from emerging technologies.
4. Use a Structured Methodology
Choosing the best Conceptual Design isn’t just intuition—it’s a process. Think of it like selecting the best control algorithm for a motor controller. You need a way to compare different approaches objectively.
- Weight the requirements—not all specifications are equally important.
- Rank each design concept against these weighted requirements.
- Score each concept based on how well it meets the criteria.

Why Skipping Conceptual Design Leads to Failure
Let’s say you rush through Conceptual Design and start detailed development prematurely. Here’s what can go wrong:
- Escalating Costs: Redesigning a product after prototyping is far more expensive than adjusting the Conceptual Design early on.
- Market Mismatch: If you don’t deeply understand customer needs, you might build something nobody wants.
- Unfixable Performance Issues: If a core system architecture is flawed, no amount of optimization will fully resolve the underlying issue.
We’ve seen companies invest heavily in Design Verification Testing (DVT), trying to fix fundamental design flaws that should have been caught earlier. That’s like adjusting a motor controller’s feedback loop to compensate for an undersized power stage—it’s a band-aid, not a solution.
Conceptual Design and Design Verification Testing: The Perfect Pair
A strong Conceptual Design directly impacts the success of Design Verification Testing (DVT). If your conceptual foundation is weak, DVT will expose critical failures, sending you back to the drawing board.
- Conceptual Design ensures that all possible design directions are evaluated upfront.
- DVT validates that the chosen design meets real-world requirements.
By treating Conceptual Design as the first step in a rigorous validation process, you create a smoother path to product launch.

Final Thoughts: Invest in Conceptual Design, Reap the Rewards
Just like a well-tuned motor controller ensures smooth operation, a well-executed Conceptual Design sets the stage for product success. It determines cost, performance, and usability while minimizing risks in later development stages.
To recap:
✅ Start with clear, written requirements.
✅ Gather diverse input from multiple disciplines.
✅ Allocate enough time for proper exploration.
✅ Use structured scoring methods to evaluate concepts.
✅ Treat Conceptual Design and Design Verification Testing (DVT) as complementary processes.
Investing in Conceptual Design ensures your product is built on a solid foundation—one that leads to market success rather than costly redevelopment.
