Milestone critical task Lead & Lag time in Project

1.      What is a Milestone in a project?

      

      A milestone is a reference point that marks a major event in a project and is used to monitor the project's progress. Any task with zero duration is                 automatically displayed as a milestone. You can also mark any other task of any duration as a milestone.

2.      What is a critical task in a project?

           

            Tasks which cannot be delayed without affecting the project finish date are the critical tasks. A Critical must be completed on schedule for the project               to finish on time. If a critical task is delayed, the project completion date might also be delayed. A series of critical tasks makes up a project's critical                 path.

3.      What information can help me analyze my projects progress?

           Five pieces of task information help to analyze the project progress: 

• Duration
• Work
• Start date
• Finish date
• Cost
  
  Variations of each of these types of fields help you compare and evaluate your progress.
  

4.      What is the difference between Lead time and Lag time?

      Lead time: An overlap between tasks that have a dependency.

    Lag time: A delay between tasks that have a dependency. For example, if you need a two-day delay between the finish of one task and the start of               another, you can establish a finish-to-start dependency and specify a two-day lag time
