Strategic Leadership causes and organization to most effectively accomplish a vision. This can only be achieved if all of the alternative routes to accomplishing the vision are assessed and the one that would achieve the vision with the best use of resources is pursued.
The best use of resources can only be determined if the resource usage of the alternatives are compared, which implies that models for each of the alternatives are developed and assessed.
These models can only be developed using information about the resource usage and outcomes of the alternatives. A leader cannot lead strategically without having access to likely costs and outcomes of alternative strategies for accomplishing the mission. To pretend that this can happen otherwise would be like trying to drive a car most economically without a way to measure fuel usage or distance travelled.
Any organization that cannot access detailed information about its resource usage or outcomes is not leading strategically.
