What are the Eight Phases of Change?
The Eight Phases of Change is a change management model developed by Harvard Business School professor John Kotter, introduced in his 1996 book "Leading Change." Based on research into why major change efforts fail, Kotter identified eight common mistakes organisations make and developed an eight-step process designed to avoid those mistakes and lead transformation successfully.
The model remains one of the most widely referenced frameworks in change management and is used by organisations across industries when navigating significant strategic, cultural, or operational change.
The eight phases
Phase 1: Create a Sense of Urgency — help people understand why change is necessary now. Phase 2: Build a Guiding Coalition — assemble a team with the authority and credibility to lead the change. Phase 3: Form a Strategic Vision and Initiatives — develop a clear vision of the future and the strategic initiatives that will get there. Phase 4: Enlist a Volunteer Army — mobilise a broad group of people to drive the change.
Phase 5: Enable Action by Removing Barriers — identify and address obstacles that block progress. Phase 6: Generate Short-Term Wins — create visible early successes to build momentum and credibility. Phase 7: Sustain Acceleration — use early momentum to drive deeper and broader change. Phase 8: Institute Change — embed the new approaches in the organisation's culture and systems to make them permanent.
Why change efforts fail
Kotter's research found that major change initiatives fail for predictable reasons: insufficient urgency, no guiding coalition, unclear vision, poor communication, failure to remove barriers, no short-term wins, declaring victory too soon, or failing to anchor changes in the culture.
Each step in the eight-phase model directly addresses one or more of these failure modes. Following the model does not guarantee success, but it significantly reduces the risk of avoidable failures.
Applying the model in practice
The eight phases are designed to be broadly sequential, but Kotter himself has acknowledged that change in practice is often messy and non-linear. The phases serve as a guide and a checklist rather than a rigid prescription.
What matters most is that leaders give appropriate attention to each phase rather than skipping steps — particularly the early phases around urgency and coalition-building, which are often underinvested because leaders are eager to get to implementation.
Change management and strategy execution
Every significant strategic initiative involves change management. When strategy requires people to work in new ways, adopt new tools, or let go of old habits, the discipline of change management becomes essential to execution success.
Empiraa supports change and strategy execution by providing the visibility, accountability, and communication tools that help leadership teams sustain momentum through each phase of a major change journey.
