Scheduling 2.0 - Calculations for Free Float and Total Float

NOTE: Scheduling 2.0 has been deprecated and is no longer supported by CMiC. See Product End of Support for further details.

Early Start (ES) = earliest start date of activity without affecting the project's start date.

or

Early Start = Early finish of predecessor.

Early Finish (EF) = Early Start + activity duration (including the resources assigned that also affect duration).

 

Late Start (LS) = Late Finish - activity duration (including the resources assigned that also affect duration).

Late Finish (LF) = latest end date of activity without affecting the project's end date.

or

Late Finish = Late start of successor

 

Early Float (EFS) = Difference between early start and late start.

Late Float (LFF) = Difference between early finish and late finish.

 

Free Float = Difference between activity end date and activity's earliest successor start date.

Total Float = Minimum between early float and late float.
