Pritchard | The Critical Chain technique has now become a standardized practice and has evolved to the point where practitioners feel comfortable arguing about the practice and the nuances of implementation. | ||
The way CPM (critical path method) schedules were calculated in the 1970s and 80s (prior to the availability of low-cost PC scheduling tools) used a simplification designed to minimise error and speed up a tedious task. | |||
Time Analysis calculations in a Precedence Diagramming Method (PDM) Critical Path | |||
The concept of ‘float’ is less than 60 years old. The existence of a critical path and non-critical activities (with their associated ‘float’) grew out of the science of scheduling as defined by Critical Path Analysis | |||
Time scheduling calculations can be done in a number of different ways. This article offers a standardised set of calculations and notes areas where different software tools may produce different outcomes. |
