My answer to In project management, what soft skills are the most important for success?
Answer by Ken Larson:
DEVELOP the ability to cross organizational lines and make disparate groups or functional organizations work together with only your power of persuasion and your contract going for you.
EVOLVE the art of directing resources without having them report to you while keeping home departments and functional bosses happy at the same time.
MANAGE to convince the executives in your company that your project (s) is the most important in the firm.
LIVE with the prospect that if the project is late, fails or otherwise disappoints the powers that be, replacing you will be the designated corrective action.
GROW to crave the satisfaction that comes from succeeding at the above challenges and you would not have any other job because no other pursuit makes your day go as fast, grows you skills as sharp and totally occupies your intellect.
