Critical Path issues.

Hello All,

Is there a way to make the last activity non-critical. On a number of projects I have a critical path which includes the last few activities because they are last; and not really critical? (although I understand the logic that if they slipped the project would slip)

I have, for a work around, used project finish milestones and linked the last activity in the critical path to it to get around this (making the milestone the last activity.)

Is this the only way to get around this ?

Thanks in advance,

Kevin.
