Pick the sentence that sounds most like your week and it routes you, including the branch that separates “can’t” from “won’t”.

Use the interactive router →

A decision tree for when you don’t know where to start.


“People aren’t using the new system.”

Do you know why yet — from talking to them, not from a survey?

⚠️ The single most common error: assuming “won’t” when it’s “can’t”. Managers reliably over-attribute to attitude. See Myths and Traps in Change Management.


“We need a change plan by Friday.”

Change on a Page → fill it in → The One-Page Board Narrative for the exec version.

If you have 90 minutes with the right people first, run Workshop — Behavioural Diagnosis (90 min) and the plan writes itself.


“The sponsor isn’t showing up.”

Sponsor Briefing Pack to make the ask concrete → Leader Behaviour Contract to make it visible → Challenging Upward — Scripts if it continues.

Active, visible sponsorship is repeatedly identified as the largest single contributor to change success. A quiet sponsor is not a minor risk — it is the risk.


“Leadership say the right things but do the opposite.”

Executive Failure Modes (specifically Say–Do Gap) → Leader Behaviour Contract.

The organisation reads behaviour, not memos. One leader visibly bypassing the new process undoes six weeks of comms.


“There’s a lot of resistance.”

Resistance Decoder first. Resistance is almost always one of: unclear ask, real cost you haven’t acknowledged, loss of status/competence, prior broken promises, or a genuinely bad design. Only the last one is your fault, and only the last one is a compliment.


“We rolled out. Adoption spiked then dropped.”

Textbook drift. Habit Loop and Behavioural DriftDrift Check — 30 60 90Embedding and Reinforcement.

The spike was novelty and supervision. The drop is the true baseline. Design for the drop.


“How do we know if it’s working?”

Measurement Plan — Leading and Lagging. If your only metric is “training completed” you are measuring attendance, not change.


“We need to change the culture.”

You can’t change culture directly. You change behaviours; culture is the residue. Go to Target Behaviour Definition and force the aspiration (“more collaborative”, “more accountable”) into observable actions. If you can’t film it, it isn’t a behaviour.


“Everyone’s exhausted — there’s too much change.”

Real and legitimate. Change Readiness Assessment has a saturation section. The honest advice to a senior leader is often sequence, or stop something. Bring them the list of what’s already running.
