Breakthrough strategies rarely fail because the original insight was wrong. They fail in the handoff — in the gap between the function that generated the idea and the constellation of other functions, partners, and external actors who must change their behavior for the idea to reach its potential. The commercial merit of the strategy survives intact inside the originating team. It dies in translation.
Research published in the Harvard Business Review by Linda A. Hill in the March/April 2026 issue introduced a tripartite taxonomy for innovation leadership — Architects, Bridgers, and Catalysts — and identified the bridger as the archetype most consistently absent from organizations that fail to scale their innovations. Unlike conventional hierarchical managers who coordinate through formal authority and reporting structures, bridgers operate through contextual and emotional intelligence.
They understand both sides of an organizational interface — the language, the incentives, the professional vocabulary, the implicit priorities — and they build the mutual trust required for people who do not naturally coordinate to make shared commitments. Organizations that lack them do not simply execute their strategies more slowly. They watch those strategies devolve into territorial disputes between functions that cannot find common ground.
Why silos persist despite awareness
The persistence of organizational silos is not primarily a structural problem. It is a relational one. Every large organization understands, at an intellectual level, that cross-functional coordination is required for complex strategies to succeed. They invest in matrix structures, cross-functional working groups, and integrated planning processes. These investments consistently underperform because they address the architecture without addressing the relationships that the architecture was supposed to enable.
Tiziana Casciaro, Amy Edmondson, and Sujin Jang, researching cross-silo leadership across global organizations, found that the most valuable innovation opportunities lie at the interfaces between functions, offices, or organizations — but that horizontal collaboration remains "devilishly difficult to implement effectively" despite its recognized value. The difficulty is not conceptual. Organizations know they need it.
The difficulty is interpersonal: learning about people on the other side of the interface and building the capacity to relate to them. Employees who can reach outside their silos to find colleagues with complementary expertise learn more, sell more, and gain skills faster. But the conditions required to do this reliably do not emerge from org charts. They emerge from repeated, structured contact that builds the mutual understanding across which genuine coordination becomes possible.
The village dependency problem at scale
In complex strategic challenges — pharmaceutical launches that require simultaneous coordination of clinical, payer, patient support, and commercial functions; government modernization programs that span bureaus with incompatible systems and cultures; health system transformations that require clinicians, administrators, and community partners to change behavior simultaneously — the bridger is not a nice-to-have. The bridger is the mechanism through which village dependency gets resolved.
Without someone who can hold the full coordination requirement in view and translate across the incentive structures of each party, the village dependency remains theoretical. Each actor continues to optimize locally. The strategy requires them to optimize collectively. No mandate from the top can close that gap without the relational tissue that makes collective optimization feel safe and achievable.
Linda Hill's research into collective genius — the conditions under which organizations produce repeated innovation rather than one-off breakthroughs — found that innovation leaders do not set a vision and expect others to execute it. They create communities willing and able to generate new ideas. They manage the tension of clashing perspectives.
They foster what she calls creative abrasion — the productive friction between genuinely different views that generates options that no single perspective could have produced. This is the bridger's work at a team level. The capacity to hold difference in productive rather than destructive tension. The ability to sit in a room where people's professional incentives diverge and move them toward a shared commitment without resolving the divergence by suppressing it.
The structural substitute
Michael Tushman's foundational research on boundary roles in the innovation process established empirically that organizations require specific individuals to act as nodes — translating information across organizational boundaries and preventing the isolation of strategic initiatives within the function that originated them. This finding has held across fifty years of organizational research. What changes is the scale and complexity of the boundary-spanning problem, which has grown as organizations have become larger, more global, and more dependent on external ecosystems for execution.
The organizations most exposed to bridger deficits are those whose senior leaders have spent careers deepening expertise within a single function and have consequently built their organizational instincts around vertical authority rather than horizontal influence. When those leaders convene cross-functional strategy sessions, they tend to manage the session from the top — setting the frame, controlling the agenda, resolving conflicts by decision rather than by dialogue. The result is a session that produces apparent alignment without producing the genuine mutual understanding that alignment requires. The bridger performs the work that the session design in those organizations never gets to.
The structural substitute for the bridger — when the organization's bench does not include enough of them — is a convening process deliberately designed to perform the bridging function. Not information sharing. Not presentations across functions. But structured, facilitated contact in which the people who must coordinate are required to name their actual constraints, surface their real incentive conflicts, and build specific mutual commitments before they leave the room. The strategy may survive the absence of bridgers in the organizational hierarchy if the process that produced it did the bridging's work.
Frequently Asked Questions
Why do complex strategies fail to scale across organizations?
The most common cause of scaling failure is not the strategy's commercial merit but the absence of individuals who can translate priorities across operational silos with different cultures, vocabularies, and incentives. Without people who can operate as genuine boundary-spanners, complex strategies devolve into territorial disputes between functions that cannot find common ground.
What is a bridger and why are they critical to strategy execution?
A bridger is a leader who possesses the contextual and emotional intelligence to curate partners, translate priorities across distinct operational silos, and integrate disparate ways of working. Unlike hierarchical managers who rely on formal authority, bridgers build mutual trust and influence across boundaries that reporting lines do not follow. Research into innovation scaling identifies the bridger as a frequently missing but critical enabler of complex strategic implementation.
How can organizations compensate for a bridger deficit?
The most direct structural solution is to deliberately convene the cross-boundary actors whose coordination is required — before the execution phase begins — and to design that convening around explicit trade-off resolution rather than information sharing. When bridgers are absent from the organizational bench, the convening structure itself must perform the bridging function: creating the shared context, surfacing the conflicting priorities, and forcing the mutual commitments that bridgers would otherwise build informally over time.
