Competing commitments (Immunity to Change)

Why sensible change stalls

Immunity to Change is used as a trademark by Minds at Work. Named here to identify the model. No affiliation or endorsement.

Use when

A change everyone agreed to is not happening, and nobody is visibly opposing it

Competing commitments (Immunity to Change), shown as a sequence of 4 parts: Improvement goal, Doing / not doing, Hidden competing commitment, Big assumption.
  1. 1

    Improvement goal

    The change you genuinely want, stated as behaviour, not aspiration

  2. 2

    Doing / not doing

    The honest inventory of behaviours working against the goal

  3. 3

    Hidden competing commitment

    What those behaviours are brilliantly protecting you from

  4. 4

    Big assumption

    The belief that makes the competing commitment feel necessary. Test it small

The failure to change is not a deficit. It is the success of an invisible commitment.

How to use it

Run it one person or one team at a time, in writing, over an hour. The move is not exhortation: surface the competing commitment, name the big assumption behind it, then design the smallest safe test that could disconfirm it. Watch-out: it is developmental work, not a workshop icebreaker; do not run it where psychological safety is low.
