Change is Good - Up to a Point

One of the most often, and often most challenging issues faced by managers is getting change to "stick." A change in process or procedure is agreed to and implemented. Now everyone will do it that way. Right? Well, often, not. Pretty soon, one or more have reverted to the old way of doing it. No apparent reason. No "I don't like the new way so I'm going back to the old way." Folks just slip back to the prior way of doing things. The change doesn't "stick."

Here's a (kind of) scientific explanation for why this is true and why it's so hard to change. Self-Control is Exhaustible

That's why we always encourage follow up as part of implementation. Once the training is done and the change is made, there needs to be provision to regularly - and consistently - check to see if the change is still in place. If there is no expectation of follow-up and follow through, then there is no requirement for self-control - no requirement to stick with the change until it is the new habit.

If you want your changes to stick, you'll have to stick to your changes.
