Resistance to change is natural.
Involvement leads to commitment.
This is one of the most fundamental axioms of human behavior. As you plan your project, think about ways to pull people into the process. This means not only employing tools and techniques that promote hands-on participation, but also creating a project culture that values massive involvement. Know that it is not necessary to involve everyone in the creation of the strategic solution. Understand that the same people who develop the strategy will probably not be the ones who implement the solution.
