From Rosabeth Moss Kanter at Harvard Business Review: Companies can make strategic choices once they know what conditions will apply — will laws change, will taxes be raised or lowered, will interest rates go up or down? You could be a CEO weighing factory location decisions in the U.S. or abroad, or a retail entrepreneur deciding where and when to open more stores. Waiting for decisions that provide a direction, any direction, can be paralyzing. Motivating people to try something new, or to get on with innovation, is tough when the rules of the game are up in the air. Uncertainty is one of the primary reasons that people resist change. People are relatively adaptable once they know what the situation is, like it or not.
