Voice of customer (VOC) is one of the most widely accepted principles and practices in product development. And yet, many organizations continue to face a familiar challenge: translating customer input into clear product direction. The issue isn’t whether teams are talking to customers, it’s how they’re doing it.
We believe organizations should approach VOC as a means to define problems clearly enough for engineers to act on them, not as a way to collect feedback. When done well, VOC produces stronger specs, reduces internal debate, and accelerates speed to market.
This was a key theme in Phase 5’s recent webcast with the PDMA, “From Pain Points to Product Success with Problem-Led Insight.” The session focused on how teams can uncover more meaningful signals from customers, and highlighted a broader issue: the voice of the customer is often present but rarely structured to drive decision.
Continuing that line of thought, here we explore why voice of customer research remains difficult to apply in practice and what gets in the way of turning customer insights into direction.
Why VOC Is Important and Where It Often Falls Short
Most teams don’t ignore VOC; they just don’t get enough value from it.
In many industrial and B2B environments, familiarity plays a role. Years of experience and stable product categories create the sense that customer needs are already understood. But in mature markets, customers adapt. Workarounds become routine.
What appears to be stability is often a form of normalization. The signals are still there, but they are embedded in behavior rather than explicitly stated.
At the same time, voice of customer research is often conducted under time pressure. It becomes a step in the process, something to complete before moving forward, rather than a tool for shaping direction.
The result is predictable: teams gather input, but struggle to answer a critical question: What product features should we actually build?
The Real Gap: From Insight to Specification
One of the most consistent barriers to effective VOC is not access to customers, but the ability to translate what is heard from them into something the organization can act on.
Customers describe their world in operational terms:
Product development teams, in turn, need to make decisions that are structured and forward-looking, such as:
Without a clear translation step, insights remain open to interpretation. Teams revisit the same inputs from different perspectives, leading to misalignment and extended debate. Our approach to innovation is built around this step, ensuring that customer insights connect directly to product and business decisions.
How Do You Use VOC Effectively?
The most effective VOC approaches are structured around real situations and, because they are translated effectively, produce a different kind of output.
Instead of asking what customers want, we recommend focusing on:
This shifts VOC from opinion gathering to problem definition. And from there, the goal is clarity:
When product development teams reach this level of definition, they can move directly into product decisions with less ambiguity, reducing the need for repeated interpretation and helping them align around a shared understanding of what matters.
Over time, this leads to faster decisions, stronger alignment, and a more confident path forward.
Why This Becomes More Critical in Mature Categories
The importance of voice of customer insight increases as categories mature.
In environments where products are widely adopted and expectations are well established, differentiation becomes harder to achieve through incremental change alone. Signals of opportunity are often embedded in operational realities, such as downtime, maintenance effort, and troubleshooting complexity, rather than in explicit requests.
Because these challenges are experienced regularly, they are rarely described as new or urgent. They are understood as part of the job.
This creates a gap between what customers say and what they experience. Bridging that gap requires deliberate effort to surface and interpret those patterns.
Moving Forward with VOC
Voice of customer research remains one of the most powerful tools available to product teams, but its value depends on how it is applied.
If your current approach to VOC is generating input but not clarity, it may be time to rethink how it’s structured. We can help you turn customer insights into stronger specs, faster decisions, and better market outcomes. Contact Phase 5 today to learn more.
