Chapter 7, Problem 20P
Summary Introduction
Interpretation: Duration of the project is to be calculated.
Concept Introduction: Critical path is the arrangement of project activities which gives an estimate time duration under which project will be completed. The project activities may include float activities which can be delayed focusing on the shortest time duration.
PERT diagram is a graphical project management tool used to organize and analyze project and it’s activity. It defines time duration for a project and also for each activity in a project.
Early start time: The rule for early start time of a task is that it is equal to largest early finish time of the task’s immediate predecessors.
Early finish time: The early finish time of a task is addition of both task time and early start time of the task.

Students have asked these similar questions
A project consists of Six activities: A,B,C,D, E, F. A and B have no preceding activities, but activity C requires that activity B must be completed before C can begin. Activity D cannot start until both activities A and B are complete. Activity F can start any time. Activity E requires activities A and C to be completed before it can start. If the activity times are A: 10 days; B: 4 days; C: 8 days; D: 3 days, E = 2 days, and F: 1 day,
* Find out the minimum time possible to complete this project.
* Are there any critical path activities? Which one are those?
There are six processes in the project time management knowledge area. How do these processes interact in the creation of the project schedule?
A project has four activities that take 4, 3, 6, and 7 days, respectively. What is the totalcompletion time for the project?a. 3 days, because this is the minimum timeb. 7 days, because this is the maximum timec. 20 days, because this is the sum of the timesd. It is not possible to determine the total completion time from the given information
