It is an interesting time at my work. We are working to break a culture of "good enough." From a role in the quality department this is exciting as we are leading many of the changes. The counter to that is each change we implement must be sold to the entire team and both my team and I regularly run into stiff resistance to change.
Selling the change seems to be key as we move to improve. Communicating the "why" and getting buy in from your key team members will help ease the transition. Many times I see the resistance come from a feeling of management dictating what we will be doing moving forward.
As a manager or change agent you know who your key players are on the floor, get to them. Explain the "why," for the company, and for them. This communication is key, if they know why, they will explain it and sell it to their peers better than you ever could. Buy in at this level, followed by effective training on the change, leads to successful implementation.
