PMBOK® Guide Sixth edition: Difference between Total Float & Free Float
ฝัง
- เผยแพร่เมื่อ 4 ต.ค. 2024
- The video starts with 3 terms
Total Float, Free Float, and Negative Float.
By default Float or slack actually means Total Float
Total Float: This term is given for the float for a given path, so the path which you have and the flexibility for that given path. Total Float is the schedule flexibility or amount of time that a schedule activity can be delayed or extended without delaying the project finish date. In simple words, it is a flexibility or relaxation without impacting the final date of the project.
Free Float: It is the amount of time that a schedule activity can be delayed without delaying the early start date of any successor. So in simple language free float is the flexibility at activity level and total float is the flexibility at the path level.
The formula for Total Float
Total Float = Difference between Early Finish and Late Finish
OR
= Difference between Early Start and Late Start
Usually, float means positive, you have flexibility, you can delay some part of the work.
Negative Float is reverse, it is a temporary situation, a respiration point, and you can do something to get it settled in the end. Negative float analysis helps to find possible accelerated ways to bring a delayed schedule back on track.

Total float - the float available for the whole path and free float is only for one activity ✔️. No formula to calculate free float. Thank you for the excellent explanation
I have already attended some classes, and the way you explain the concepts is fantastic

Free float effects preceding activity
Thank you so much
I wanna know how to deal with lags if I found any
Specially if the act. which has lag depends on to activities
Thanks for the explanation. i have a doubt.
in case of parallel processing the total float of some activities may be negative? how? can you explain? or probably put a video on it
Nicely explained
Thanks for tour kind words!! Keep an eye to see more PMBOK6 videos, we publish them on regular basis.
I hope you solve some ex.
Best explanation. But what about the Project float?

Can free float affects the predessor activity
Free float is considered in relation with its successor activity. It is the time for which we can delay an activity without delaying the early start date of any successor. So it does not impact predecessor activity.
How to identify the Total float, Free float & Negative float for given PDM.
Start -- A -- Duration - 2days; A to B & A to D
B -- Duration - 3days;
B to C - C -- Duration - 1day;
C to G - G -- Duration - 2days --> End
A to D - D -- Duration - 4days;
D to E - E -- Duration - 1 day;
E to F - F -- Duration - 4days;
F to G - G -- Duration - 2days; --> End
To calculate total float, understand the whole work complete date, and days that are needed to complete the critical path. If you have 25 days to finish work and the critical path will take 20 days, then you have 5 days of total float. You may have a negative float like you estimated to finish an activity in 10 days, but due to an upcoming festival, you have to finish it in five days. Here, you have a negative float of five days. The free float can be at any activity level if its successor start time is delayed, so it has some flexibility. For more details, please refer: www.izenbridge.com/blog/what-is-float-calculate-total-free-float/
Fee float is time period for any activity can be delayed without affecting Early start of successor activity.
Thank you!! Binit, for exploring our content.
Yes Free Float is the amount of time that a schedule activity can be delayed without delaying the early start date of any successor. So free float is the flexibility at activity level and total float is the flexibility at the path level.

Is negative float and independent float the same sir?
No, independent float and free float are different.
Free Float - You have some flexibility to delay an activity. And, when you consume that flexibility even then, its successor activity can start at its early start. It does not need to begin at Late Start.
Independent Float - In the case of the independent float of activity - The situation is even if its predecessor finishes at late finishes, the successor of that activity can begin at its Early Start.
For example -
Duration of an activity is 2
Its predecessor late finish is 4
It's successor Early start is 8
When predecessor finish on day 4 by it's Late Finish, the activity in question finishes by day 6, but you can finish it by day 8 as next activity early start is 8
So activity in question has an independent float.
In the case of Free Float, we don't see when its predecessor finishes.
