Bridges transition model — Organizational Development

William Bridges distinguishes change from transition:

Change is situational and external. It happens on a date: a new structure, a new system, a new manager.
Transition is psychological and internal. It is the process people go through to come to terms with the change, and it has no date.

Bridges' central claim: transition starts with an ending, not a beginning. Organizations manage change and neglect transition, then are baffled when a technically successful implementation produces a demoralized workforce.

Evidence: Weak. Not validated as a staged theory, and the phases have no established durations or boundaries. The change-versus-transition distinction is conceptually useful and consistent with the job insecurity and organizational grief literatures, which document real performance and wellbeing effects from loss during restructuring. The specific three-phase structure is a clinical framework, not a finding.

Use when: the change is done and it is not working; when people who agreed with the change are behaving as though they did not; when there has been loss.

Do not use when: you need project mechanics. This model manages people, not plans.

The three phases

Ending, losing, letting go. People must let go of the old way and the identity that went with it. Expect denial, anger, bargaining, anxiety, and grief. The work here is to name what is genuinely ending and honor it.
The neutral zone. The old is gone, the new is not yet operational. Productivity drops, anxiety rises, old weaknesses resurface, and people are simultaneously exhausted and creative. This phase is the hardest and the most important. It is also where most organizations declare the change complete and withdraw support.
The new beginning. New identity, new energy, new sense of purpose. Cannot be forced or scheduled; it emerges when people have made sense of the neutral zone. Bridges: beginnings occur after endings and the neutral zone, never before.

The phases overlap and different people are in different phases at once, including within one team.

Managing each phase

Ending

Name precisely what is ending, and for whom. Vagueness prolongs it.
Identify who loses what: status, competence, relationships, territory, routine, meaning, future plans.
Do not denigrate the past. People helped build it; attacking it attacks them.
Mark the ending explicitly. Ceremony is not sentimentality; it is a signal.
Give information repeatedly. Anxiety destroys retention.

Neutral zone

Say out loud that this phase exists and that it feels bad. Normalizing it is the single highest-value intervention available.
Set short-range goals; the horizon is short in this phase.
Protect people from additional change. Do not stack initiatives here.
Use the phase for experimentation — this is when the system is most plastic.
Increase the frequency of communication even when there is nothing new.

New beginning

Communicate the four Ps: Purpose, Picture, Plan, Part to play.
Reinforce quickly and visibly; early inconsistency resets the whole process.
Celebrate the new, not the survival of the transition.

Examples by audience

Health care: a service reconfiguration ends a team that worked together for fifteen years. The rota is the change; the loss of a functioning team and a professional identity is the transition. Clinicians who "resist" a clinically sound reconfiguration are usually in the ending phase and being told they are being obstructive.
Software: migrating off a long-lived internal system ends the expertise of the people who knew it best. Their reluctance is rarely technical conservatism; it is loss of hard-won mastery and status. Name it, and give them a visible role in the new system.
Executive: an executive who has been through the ending privately over months announces the beginning on day one. The organization hears a beginning before it has had its ending, and the mismatch reads to the executive as resistance. Slow down and start with the ending, publicly.

Limitations

Not empirically validated as a staged theory.
Can be used to pathologize legitimate disagreement: "they're just in the neutral zone" is a way of not listening. Some resistance is correct.
Offers little guidance on structural or technical work.
