PERT and CPM

Programs, also known as Project Management and Review Technique (PERT), are useful for projects where the time required to complete various activities is unknown. The Critical Path Method, or CPM, is best suited for tasks that repeat themselves (recur). PERT and CPM are two project management approaches that every manager should use to meet a project’s final goal on time. Here are the crucial MCQs on the PERT and CPM to help you assess your knowledge of the subject. For your convenience, the answers are also provided.

MCQs (Multiple Choice Question)

Q1 What is the basis for PERT analysis?

1. 1. An optimistic time
   2. A pessimistic period of time
   3. The date that is most likely
   4. All options mentioned above 

Ans- D is the correct answer. PERT is a method for calculating the quickest way to complete a project by looking at all of the jobs involved and the time needed to complete each one.

Q2 Which of the following options does not pose a significant difficulty when it comes to project scheduling? 

1. 1. There are deadlines. 
   2. Self-directed activities 
   3. An excessive number of staff may be necessary. 
   4. Expensive postponement 

Ans- B is the correct answer. Initiation, planning, implementation, and completion are the four essential phases of a typical project.

Q3 What is the name of the task performance in CPM?  

1. 1. Dummy 
   2. Occasion 
   3. Exertion Contract 

Ans-C is the correct answer. Contract is the name of task performance in CPM. 

Q4 What is the rule for the earliest start time? 

1. 1. It compares the activity’s start time to that of a successor activity. 
   2. It compares the activity’s end time to that of a previous activity. 
   3. It specifies when a project may begin. 
   4. It establishes the start date for a project. 

Ans- B is the correct answer.  Given that all antecedents must be completed, the earliest start time is the earliest moment at which the activity can begin.

Q5 What is the definition of a critical path?

1. 1. It’s a path that connects the starting and ending nodes. 
   2. It combines all of the paths. 
   3. It is the shortest route. 
   4. It is the most direct route. 

Ans- C is the correct answer. In order for a project to be finished, each step along the critical path must be accomplished.

Q6 The execution of a CPM network diagram activity is typically referred to as what?

1. 1. Connector 
   2. Occasion Node 
   3. All of the preceding 

Ans- C is the correct answer. Both of these are the typical name connector and occasion node.

Q7 The activities A, B, and C are the direct precursors of Y. What is the earliest starting time for Y if the three activities’ earliest finishing times are 12, 15, and 10? 

1. 1. 10 
   2. B.15
   3. 12
   4. It’s impossible to say.

Ans- B is the correct answer.  

Q9. What is the symbol for activity in a network diagram? 

1. 1. Rectangles Arrows 
   2. Squares 
   3. Circles  

Ans- B is the correct answer. It is a square symbol.

Q10. A PERT chart’s full name is________.

1. 1. Evaluation and Review Techniques for Programs
   2. Evaluation of Programs and Robotic Techniques
   3. Assessment of Programs and Robotics
   4. Technology for Program Evaluation and Rating

Ans-A is the correct answer. PERT full form is Evaluation and Review Techniques for Programs.

Q11. The maximum time that would be required to accomplish an activity, according to the time estimates generated by PERT planners, is referred to as _________ 

1. 1. The time estimate that is most likely
   2. Time estimate that is optimistic
   3. The time estimate that is pessimistic
   4. The time estimate that is expected

Ans- C is the correct answer. The pessimistic time estimate refers to the maximum amount of time that would be required to accomplish an activity based on the time estimates produced by PERT planners. 

Q12. Which colour is used to illustrate actual progress in bar charts?

1. 1. Red 
   2. Black 
   3. Blue 
   4. Green

Ans- D is the correct answer. Different colours are occasionally used to fill in the bars in bar charts to display varied control information.

Q13. A PERT network focuses on activities, whereas a CPM network focuses on events.

1. 1. True 
   2. False

Ans- B is the correct answer. A CPM network focuses on activities, whereas a PERT network focuses on events. The end of an activity or the beginning of an activity is referred to as an event.

Q14.  Who was the first to use bar charts?

1. 1. Henry Williams 
   2. Henry Gantt 
   3. Jane Gantt 
   4. Henry Joseph

Ans- B is the correct answer. Around 1900 A.D., Henry Gantt invented bar charts. They provide a two-dimensional graphical picture of a project.

Q15. Later, milestone charts were created by modifying bar charts.

1. 1. True 
   2. False

Ans- A is the correct answer. Bar charts, milestone charts, and network diagrams are some of the project management tools and methodologies.

Q16. CPM stands for

1. 1. Critical Path Method 
   2. Control Path Method 
   3. Critical Plan Management 
   4. Control Path Management 

Ans- A is the correct answer. The full form is Critical Path Method.

Q17. The quickest time in which a task may be completed under perfect conditions is referred to as 

1. 1. The most pessimistic time estimate 
   2. The most optimistic time estimate 
   3. The expected time estimate 
   4. The most likely time estimate

Ans- B is the correct answer. PERT planners make three different types of time estimations. The most likely time estimate, the pessimistic time estimate, and the optimistic time estimate are the three options.

Q18. The ________ is the difference between both the allotted time and the actual time needed to execute a task.

1. 1. Free float 
   2. Independent float 
   3. Total float 
   4. Half float 

Ans- C is the correct answer. The total float is the difference between the maximum amount of time permitted and the actual amount of time necessary to accomplish a task or task sequence.

Q19. The goal of network analysis is to

1. 1. reduce the overall project duration
   2. reduce the entire project cost
   3. keep production delays, interruptions, and conflicts to a minimum
   4. extend the project’s entire time

Ans- A is the correct answer. They are to reduce the time to complete duration.

Q20. _____________ is a type of activity that does not require any resources or time.

1. 1. there is no activity
   2. a dummy action
   3. the preceding activity
   4. unique action

Ans- B is the correct answer. This is the dummy action that doesn’t need resources and time.
