“You don’t get results by focusing on results. You get results by focusing on the actions that produce results.” Mike Hawkins.
So, work backwards from the results you want (probably behaviour change), to the actions that people need to do to get those results, to how you will enable them to take the required actions.
Those actions will take place immersed within the organisational culture. Is the culture friendly or inimical to the actions that people need to do to get the results you want?
If the culture needs to change, each person is part of the solution or part of the problem.
Some people stand higher than others; these are the people whom others see as leaders. What they do and what they say, and what they don’t do and what they don’t say, are clues that others use as a basis for their own behaviour.
Who can help you by being part of the solution, and who might be a barrier?
In the words of Gandhi, who can “Be the change you want to see in the world”?
Find them and enlist their help.
My best wishes, Paul
