the float may be positive, zero or negative

to concentrate his attention on critical activities

to divert the resources from non-critical advanced activities to critical activities

to be cautious for avoiding any delay in the critical activities to avoid delay of the whole project

all of the above

independent float = total float

independent float > free float

independent float < free float.
