Strategy. Action. Results.
We believe that creating a plan gets in the way of having a plan. Too many times, team members with the best of intentions drill into the details and unearth the various challenges we will face as we pursue a strategy. As a result, the strategy unravels before it really gets started. Our philosophy is to not mix “what” with the ‘how”. Two distinct team discussions are needed to produce a strategy and the plan for implementation.
