Gary Hamel and C.K. Prahalad, whose 1996 book Competing for the Future highlighted what they called the “40-30-20 Rule” of strategic planning.
By that they meant that most senior executives spend less than 40% of their time focused on the world outside their own organization, only about 30% thinking about the next three to five years, and no more than 20% of their time talking with their colleagues about the future to build a common view. In other words, only about 2.4% of management time (40% x 30% x 20%) is focused on building a corporate view of the future.
Yes, that’s right - 2.4%!
