Change + Uncertainty = Chaos

We know there will be change.  Not just change, but waves of change.  This is an absolute given.  It is the one variable in the equation that cannot be controlled.  Therefore, the less uncertainty you as a manager and leader create, the less chaos that will result.  As an engineering leader, your priority should be to reduce the amount of uncertainty that surrounds change.  If you allow too much uncertainty, the only result you can expect is chaos.
