Free Float greater than Total Float

Hi, 

 

I'm having an issue with Free Float v Total Float, in some instances I have Free Float which is greater than Total Float. I understand the difference between the two so I don't understand how free float can be greater than total float. I read somewhere that it could be a poor use of constraints and I have constraints in these activities / milestones to try to hold the completion dates, either Finish On or Finish On or Before. 

 

Any advice would be appreciated.

Hi Emma,

A free float greater than total float means that some activities have negative float; negative float comes from unsatisfied No Later Than constraints

Let's say Activty A starts today, is 6 working day long and has a NLT constraint next Friday; P6 gives the activity a 1 day negative float.
