The six barriers that can sit beneath execution problems
Research by Harvard Business School professor Michael Beer and organisational scholar Russell Eisenstat identified six recurring barriers to strategy implementation: a top-down or laissez-faire senior management style; unclear strategy and conflicting priorities; an ineffective senior management team; poor vertical communication; weak coordination across functions, businesses or borders; and inadequate leadership capability further down the organisation.
They described these barriers as “silent” because organisations do not always acknowledge or address them directly. Instead, the visible symptoms - missed milestones, slow decisions, competing priorities or inconsistent execution - can be treated in isolation.
Turn the barriers into organisational capabilities
The alternative is to build the capabilities that sit on the other side of those problems. Leaders need to provide clear direction while remaining open to upward influence and feedback. Strategy and priorities need to be clear enough to guide everyday decisions, and senior teams need to be able to work through constructive conflict and speak with a common voice.
Open vertical communication is equally important. Executives need a realistic view of how the organisation is operating, while people closer to delivery need a way to raise issues without those messages being filtered out. Across functions and locations, coordination needs to be designed around shared outcomes rather than internal competition. And mid-level leaders need genuine accountability, authority and development so implementation does not depend entirely on the executive team.
Why organisations can struggle to respond
Knowing the barriers is easier than changing them. Addressing them may require leaders to reconsider established behaviours, relationships and ways of working. Common responses include avoidance, replacing individual managers or engaging directly with the underlying issues.
Avoidance can preserve harmony in the short term but leaves the barrier in place. Management replacement can sometimes be necessary, but a new executive may still inherit the same systems and assumptions. Engagement is harder because it asks the organisation to surface uncomfortable information and work through it, but it is also the response most likely to build lasting capability.
Execution is an organisational discipline
Strategy implementation improves when organisations treat it as more than a project plan. Clear priorities, effective leadership, honest communication, cross-functional coordination and capable managers are the operating conditions that allow strategy to move from intent into action.
External perspective can help when established patterns are difficult to see from inside the organisation. The value is not in adding another layer of theory; it is in helping leaders identify what is blocking execution and build the practical capability to address it.
