Culture transformation hasn’t failed, but the environment it was designed for has fundamentally changed.
When we published our five principles for culture transformation over a decade ago, the dominant assumption was that culture change happened in episodes: a merger, a restructuring, or a strategic pivot. Leaders would define the culture, cascade it through the organization, and return to steady state. That model no longer reflects how organizations actually operate, particularly in life sciences organizations.
Today’s operating environment is defined by constant iteration:
- AI-enabled capabilities reshaping roles across commercial and medical
- Evolving customer models as decision-making shifts from individual physicians to health systems and payer-driven pathways
- Increasing pressure on cross-functional coordination across commercial, medical, and market access
- Continuous portfolio movement: launches, lifecycle management, and integrations happening in parallel
Organizations rarely have a moment to catch their breath between transformations. They are evolving through constantly overlapping, iterative change.
In spite of the heightened change environment, our five principles for culture transformation still hold:
- Culture work must be addressed at three levels: organizational, team, and individual.
- Culture can be intentionally shaped via the BEAR model where Results are driven by Actions, which flow from Beliefs, which are shaped by Experiences.
- Culture work requires a planned and disciplined implementation cascade.
- Culture change is accelerated by using a ‘leader-led learning’ approach.
- Culture change must leverage technology to accelerate messaging.
In today’s environment, those principles are no longer activated in controlled moments of large-scale transformation. They are activated, or neglected, continuously across everyday work. Organizations must shift the way they approach culture transformation moving forward.
Shift 1: Culture Work Must Be Activated in Every Initiative
Previously, culture work was largely initiated by large-scale change like mergers, market expansions, major restructurings. It was planned, scoped, and carried out over a defined period of time. Today, organizations face a continuous stream of overlapping disruptions:
- AI-enabled decision tools reshaping roles and how work gets done
- Shifting customer structures and payer-driven pathways
- Evolving commercial models with increasing payer and health system influence
- Continuous portfolio shifts, launches, and integrations
The biopharma commercial environment alone has been fundamentally altered. With 71% of physician practices now affiliated with health systems, the customer your field team called on five years ago is no longer the decision-maker. Prescribing authority has moved upstream, governed by EHR-enforced soft stops and institutional formularies, not individual clinical conviction.
This matters for culture because the old model assumed stability between change efforts. This stability no longer exists.
Leaders can’t wait for a “transformation initiative” to curate a strategically aligned culture. They are shaping beliefs and behaviors every day, which means that every initiative whether a product launch, an AI deployment or a shift in customer engagement strategy must also reinforce the culture the organization is trying to build. Without that intentional linkage, initiatives may drive behavior shifts that conflict with the desired culture.
Shift 2: Without Intentional Alignment, Organizations Default to Micro-Cultures
In an environment where change is constant and leaders are shaping behavior in real time, one consequence has become unavoidable: the proliferation of micro-cultures.
Every leader shapes the belief system of their immediate team through the experiences they create daily. That has always been true. What has changed is the degree of variability and the risk it introduces into culture work.
