Abstract:

Every project manager has probably thought at some point, “If only I had more time, I would be better at my job.” Unfortunately, most of us aren’t lucky enough to be given more time to do our jobs. Time is usually the project constraint that is the least flexible. We are constantly forced to prioritize our work, but don’t always make the right choices.
