We are all different and want to change at different paces, if at all! To improve processes and outcomes, they must change, but which pace is best?
I firmly believe this depends on the nature of the change and of the people required to make the change happen.
Engage with the people directly affected by the change AND those directly involved in implementing the change. Seek their views, see what they think will work best, get them deeply engaged in the nature of the change and the speed of implementation. You’ll be much more successful with them than without them.
