Every change program needs a heartbeat. Too fast and people burn out. Too slow and momentum dies. The right cadence is not a fixed formula: it depends on your pace of business change, the complexity of what you are delivering, and the capacity of the people experiencing it. This guide covers both sides of the cadence challenge: how to adapt your change approach when the business keeps shifting, and how to set up a delivery rhythm that sustains momentum without exhausting the organisation. The two are inseparable. A good cadence is both responsive and sustainable.
