Every change starts with optimism, dips into despair, and only then gets better. The dip is not a sign you were wrong.
Based on the emotional cycle of change described by Don Kelley and Daryl Conner.
People go through predictable emotional stages during a change — and the low point comes after the enthusiasm and before the benefit, which is exactly when most changes get abandoned.
Uninformed optimism. The new thing sounds excellent. Nobody has hit the difficulties yet.
Informed pessimism. The reality arrives — it is harder, slower and more disruptive than expected. Enthusiasm drops sharply.
The valley of despair. The low point, where quitting feels sensible and returning to the old way is very attractive. Most changes die here.
Informed optimism. Competence starts to build, the new way begins to work, confidence returns.
Success and fulfilment. The change is normal, and everyone forgets it was ever difficult.
Knowing the valley is coming is most of the defence against it. A team told in advance that week four will feel like a mistake behaves very differently in week four.
Pair with Kotter and Lewin: this is what change feels like, those are what you do about it.
