D1.4.4 - Total float

Total float.; Gantt (cascade) charts.; Scheduling.

Use total float to connect the rule to the data and decision in the question.

This matters because total float determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply total float to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Total float is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
