Hi Chris. Float is essentially a pause before a constrained date. The time before this date can be used to reschedule other tasks into. Lag, on the other hand, is hardwired in. A good example is concrete setting. Whatever happens a certain amount of time has to elapse for the concrete to dry. If you reschedule tasks before this period, you still have to allow for that period of time in the project plan. Schedule recruitment to take place, say, in two weeks and you can "eat into" this time by, say, scheduling more interviews.

Hope this helps,

Anthony
