The most common reason new products miss the market is not a technology failure. It is a requirements failure. The product was built to a specification that did not accurately reflect what customers actually needed — or the specification was never formally captured at all, and the development team built to their best interpretation of what the customer wanted, which turned out to be wrong in ways that only became apparent at launch.
This is the requirements problem at the heart of most commercial NPD failures. And it is almost entirely preventable.
The Requirements Architecture Problem
Most organizations that develop products have some process for capturing customer input. They conduct voice of customer interviews. They run focus groups. They survey existing customers about unmet needs. The raw material for a good requirements document almost always exists.
What typically does not exist is a structured architecture for translating that raw material into a hierarchy of requirements that can guide design decisions — and maintaining that architecture as the program evolves.
The requirements architecture in a well-structured NPD process has three distinct layers, each with a distinct function and a distinct owner. The Business Requirements Document captures what the organization needs the product to achieve commercially — revenue targets, margin expectations, market positioning, competitive differentiation goals, and strategic fit with the portfolio. The Customer Requirements Document translates the business requirements into functional terms that matter to customers — what the product needs to do, how it needs to perform, what constraints the use environment imposes. The Product Requirements Document translates customer requirements into technical specifications that the engineering team can design to — performance parameters, material specifications, dimensional tolerances, interface requirements.
These three documents are not interchangeable. Conflating them produces a document that serves none of them well.
Where Organizations Most Commonly Fail
The requirements process breaks down in four predictable places. The first is insufficient customer input — many requirements documents are written primarily from internal assumptions about what customers need, supplemented by limited external validation.
The second is late baselining. Customer requirements that are not formally baselined before design begins are not requirements — they are intentions. As the program progresses and design decisions are made, an unbaselined requirements document provides no stable reference point.
The third is broken traceability. The requirements architecture is only as valuable as the connections between its layers. The trace matrix — the document that makes these connections explicit — is one of the most consistently underinvested deliverables in NPD, and its absence is one of the most reliable predictors of commercial misalignment at launch.
The fourth is failure to update. Customer requirements are not static. Markets evolve. A requirements document that was accurate at program initiation may be significantly less accurate two years later when the product launches.
The Validation Problem
One of the most revealing questions to ask a development team is: how do you know your product requirements accurately reflect customer needs? The validation of requirements begins in the requirements phase, through structured customer engagement. It continues through prototype and beta testing. And it culminates in the commercial validation that happens when real customers use the product in real conditions.
The MKA Perspective
Across product development engagements in life sciences, bioprocessing, and medical devices, MKA has observed that the requirements problem is almost never a capability problem. The organizations we work with understand their customers, markets, and technologies. The problem is structural — requirements processes that are underdefined, requirements documents produced once and not maintained, and requirements architectures never designed to connect business intent to customer need to engineering specification in a traceable, updatable way.
Getting requirements right is not glamorous work. It produces a document — but a document that, if built correctly and maintained honestly, is the most valuable single artifact in the development program. Every design decision traces back to it. Every validation activity is evaluated against it. Every commercial claim is bounded by it.
