Time is the Enemy

business strategy development is a time sensitive process.  strategy development work is intellectually demanding, tiring, detail oriented, yet rewarding.  due to its demanding nature, strategy development is also time sensitive.  in my experience strategy efforts that take over 3 to 4 months to produce at least an initial viable product, often die of their own weight.

if your effort is likely to take longer than 3 to 4 months either rethink the goals or segment it and consider rotating some of the team members prior to subsequent phases of the effort.  that rotation will even introduce new thinking and fresh perspectives to the team.
