and Using Float
you travel on thru life brother, whatever be your goal,
Keep your eye upon the donut, and not upon the hole.

and Using Float [P110]
concept of schedule float is the creation of the Critical Path Method
(CPM) of scheduling in the late 1950s. In the 60s and 70s significant
advances ion the concept of float occurred as the ADM scheduling
methodology developed. Much of this sophistication has been lost in the
intervening 40 years as the PDM methodology gained precedence. How
significant is this loss of insight?
From a practical perspective there are two issues of paramount
paper argues that the lack of defined calculations for most of the
float values in a PDM schedule must reduce the overall value of the
schedule model compared to more rigorous approaches. But also
recognises that if scheduling is a modelling process designed to affect
the future behaviours of people working on the project (ie, persuade
them to work to the plan), other factors may be more important.
levelling and smoothing is completely reliant on having access to
accurate and understandable float values. The absence of these means
the scheduling algorithms are likely to be less efficient.
management relies on clearly defining critical and non-critical
activities and knowing how much flexibility (float) is reasonably
available on the non-critical activities.
