If activity is accelerated in the critical path, then it may no longer be the critical path, assuming some other activity now takes longer.

Why critical path is critical to project management?
Critical path method - This is the schedule network analysis technique used to identify the schedule flexibility and the critical path of the project schedule network diagram. The critical path is the longest path (sequence of activities) in a project schedule network diagram. Because it is the longest path, it determines the duration of the project and hence the finish date of the project given the start dateThe Critical Path and Duration of the Critical Path, gives the project manager a clear picture of how long all the activities can take to complete. It also helps him to identify the flexibility in the project schedule by calculating the early and late start and finish dates of each activity on each path. The schedule flexibility of an activity is measured by the positive difference between the late start date and the early start date for the activity and is called float time or total float.
If the critical path for a project with uncertain activity times is not known for certain until after the project is completed?

'project control should always focus on the critical path' comment?
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.
What kinds of decision making situations may be analysed using PERT and CPM techniques?
CPM vs. PERTCPM or "Critical Path Method":tool to analyze project and determine duration, based on identification of "critical path" through an activity network. Knowledge of the critical path can permit management of the project to change duration. A single estimate for activity time was used that did not allow for variation in activity times Activity times are assumed to be known or predictable ("deterministic") Activities are represented as nodes or circles PERT or "Project Evaluation and Review Technique":Another derivative of the GANTT chartMultiple time estimates were used for each activity that allowed for variation in activity timesActivity times are assumed to be random, with assumed probability distribution ("probabilistic")Activities are represented by arrowed lines between the nodes or circles
What is the importance of slack time critical activies and critical path?
According to Malhortra/Krajewski/Ritzman, In their book "Operations Management", The maximum length of time that a task can be delayed without procrastinating the whole project is called activity slack. Activity on a critical path has Zero slack. Information on slack is useful because it summit activities that call for close attention. In this respect, activity slack is the amount of timetable slippage that can be accepted for an activity before the entire project will be delayed. Slack at an activity is lessened when the assessed time duration of an activity is surpassed or when the planned start time for an activity must be put off because of resource considerations (1). 1- Malhortra Krajewski Ritzman, "Operations Management" , 9th Edition, Prentice Hall, NJ

What is defined by a critical path?
The Critical Path is the longest path (sequence of activities) in a project schedule network diagram. Because it is the longest path, it determines the duration of the project and hence the finish date of the project given the start date. Critical Path is one of the key outputs of the Project Schedule Creation activity
What is the significance of Critical Path Analysis in Project development?
Critical path method - This is the schedule network analysis technique used to identify the schedule flexibility and the critical path of the project schedule network diagram. The critical path is the longest path (sequence of activities) in a project schedule network diagram. Because it is the longest path, it determines the duration of the project and hence the finish date of the project given the start date.The second important feature of the critical path method is to identify the flexibility in the project schedule by calculating the early and late start and finish dates of each activity on each path. The schedule flexibility of an activity is measured by the positive difference between the late start date and the early start date for the activity and is called float time or total float.Without a proper Critical Path Analysis, an efficient Schedule for the Project cannot be created
How do critical path charts helps to analysis and manage the problems caused by delays?
Critical path method - This is the schedule network analysis technique used to identify the schedule flexibility and the critical path of the project schedule network diagram. The critical path is the longest path (sequence of activities) in a project schedule network diagram. Because it is the longest path, it determines the duration of the project and hence the finish date of the project given the start date.The second important feature of the critical path method is to identify the flexibility in the project schedule by calculating the early and late start and finish dates of each activity on each path. The schedule flexibility of an activity is measured by the positive difference between the late start date and the early start date for the activity and is called float time or total float.Note: Each activity on the critical path will always have a float time of '0'. This is because we have calculated the early/late start dates based on the critical path estimate and the other paths obviously don't take that much time and hence can afford the float time whereas the critical path activities cannot.Trivia:Each activity on a critical path has zero float time and therefore poses a schedule risk. So, you must monitor the activities on all critical paths very closely during the execution of the project.

How do you calculate EST and LST in critical path?
Early Start Time is calculated by doing a forward pass through the Critical Path. Usually the Early start for the first activity is 0 and increases as we traverse through the path Late Start Time is calculated by doing a backward pass through the Critical Path.

What if the activity is delayed in critical path?
Completion of the entire project is delayed; the entire project falls behind schedule.
