Duration and Calendar Duration, Time and Units/Time explained, P6 basic.

Time is of the essence. Both in project control and in our personal lives.

First, a delay expressed in monetary units is somewhat strange. Second, we will show later in this blog post that this metric is subject to a major fallacy. It is to be replaced with a more comprehensive one. Time for change.
