The assumption that breaks global launches

Hi {{first_name}} and happy Wednesday,

Global launches rarely fail because of engineering.

They fail because teams assume their customer is the same everywhere.

A large medical device manufacturer was preparing a new iteration of a diagnostic device designed for private practices. The product was progressing well, timelines were intact, and internal reviews were positive. Japan was identified as a key growth market, and several versions of the device were under consideration.

On paper, the differences between those versions seemed minor. In reality, the risk was significant.

The team recognized a familiar problem. Product decisions were being shaped by a US-based business development and R&D team, informed by feedback from US sales teams and local physicians. Meanwhile, the physicians who would actually use the device in Japan had not been consulted, creating a real risk that end users on the other side of the world would feel unheard.

One internal concern surfaced early:
"Will our overseas clients be happy with the new model? If we want to grow, we should no longer leave it to chance."

They came to us with a clear question:

How will physicians in Japan actually respond to the versions we’re considering, and what are we missing before we lock the design?

Here’s how we approached the problem. You can too.

We began by preparing interview scripts and messaging specifically for the Japanese market.

This went beyond direct translation. Language was adjusted for local nuance, tone, and clinical context. All materials were translated by a PreScouter team member with a life sciences background to ensure technical accuracy and relevance.

The goal was to ask the right questions in a way that felt natural to the physicians being interviewed.

We identified the true end users in Japan. The specialties and clinical scenarios where the device was used were not the same as in the US, making early validation critical.

With the right users identified, we recruited local physicians across three relevant specialties.

All interviews were conducted in Japanese to encourage open, detailed discussion of real workflows and constraints. Interviews were translated into English for analysis while preserving meaning and nuance.

We analyzed responses across specialties to identify patterns, differences, and unexpected signals.

Feedback was synthesized into a concise format that allowed the client to clearly see how each physician group responded to the proposed device iterations. We also highlighted feature requests and recommendations that had not previously been considered internally.

The focus stayed on decision clarity rather than raw data.

By the end of the engagement, the client gained:

The voice-of-consumer study replaced assumptions with evidence before final design decisions were locked.

You may not be launching a medical device. But if you are expanding into new markets, the lesson is familiar.

Customer insight does not travel automatically across borders. Local context shapes perception, adoption, and value in ways that are easy to overlook from a distance.

Teams that listen early make better decisions later.

If your next launch depends on how real users respond, clarity before commitment matters.
