Delaying the acquisition of the glass is likely to delay the entire project - this activity will be on the critical path and have no float, of any sort, attached to it and hence it is a 'critical activity'. the paint cannot be bought until it has been chosen, the new window cannot be painted until the window is installed and the new putty has set. obtaining the glass, obtaining the putty, choosing the paint etc., while others are consecutive e.g. Some of these activities can run concurrently e.g. There are various component activities involved in the project as a whole obtaining the glass and putty, installing the new glass, choosing the paint, obtaining a tin once it has set, wiping the new glass free of finger smears etc. Example Ĭonsider the process of replacing a broken pane of glass in the window of your home. Float is core to critical path method, with the total floats of noncritical activities key to computing the critical path drag of an activity, i.e., the amount of time it is adding to the project's duration.
The total float represents the schedule flexibility and can also be measured by subtracting early start dates from late start dates of path completion. The total float of a path is the combined free float values of all activities in a path. If a project network chart/diagram has 4 non-critical paths then that project would have 4 total float values.
project completion date (" total float").
In project management, float or slack is the amount of time that a task in a project network can be delayed without causing a delay to: ( December 2007) ( Learn how and when to remove this template message) Please help to improve this article by introducing more precise citations.
