Not necessarily. Critical path analysis determines the longest path through a network of project activities, because the main purpose of understanding the critical path is to focus effort on activities that lie on this path, thus increasing the chances of finishing the project on time. If you solely only focus on the critical path activities, then chances are that the activities not on the critical path will soon be on the new critical path because you haven't taken sufficient time to focus on all the activities. Project control should focus on the project as a whole, however more emphasis can be placed on the critical path activities as well as any risky/uncertain activities that could (if not monitored closely) eventually become a critical path activity and push the end date out even further.
