Following Analysis Methods Usually Richland Colle

there are 4 questions, answers is already provided. i just need to explain why i choose that answer. i have to provide reason to choose that answer.

This assignment is about which option did I pick and why I picked that option? Please provide reason/opinion why you choose that option for your answers but did not choose any other options..please send me about more specific reason in contrast to pick that answer? thank you You can use any references like google or Book name which is provided below.

Question 21)

You just completed developing the schedule for your project and got the approval from stakeholders and the sponsor. One of the team members assigned to work on a critical component informs you that she needs additional time to complete her activities as several relevant pieces were missed during planning. Her updated estimate would have no impact on the critical path; thus, the project duration would be the same. The best approach the project manager may take in this situation will be:

A. Find a replacement for the resource who can complete the task within the allocated time.

B. Inform the resources that it is too late for any kind of change in the project schedule.

C. Inform the resources that it is OK as you have sufficient schedule reserve to handle this kind of situation.

D. Update the project schedule and other relevant plans to reflect the new estimate.

I picked A

23)	Your project currently has ten more people assigned to the team besides you. As your project is getting delayed, management wants you to add four additional team members to your project at the end of the month. How many more communication channels will you have once the additional team members are added?
	A.	55
	B.	50
	C.	105
	D.	160

I picked C. 105

37)	While working with your team members on activity sequencing, a team member identifies that even though a series of activities are planned to be completed in a specific sequence, they can be performed in parallel. What type of activity sequencing method may be utilized in this situation?
	A.	Critical path
	B.	Resource leveling method
	C.	Monte Carlo simulation
	D.	Precedence Diagramming Method (PDM)

I Picked A.

26)

Which one of the following analysis methods usually use Monte Carlo simulation to simulate the outcome of a project by making use of the three-point estimates (Optimistic, Pessimistic, Most Likely) for each activity, a huge number of simulated scheduling possibilities, or a few selected scenarios that are most likely, and the network diagram?

Precedence Diagramming Method (PDM)

What-if-scenario analysis

Critical chain method

Resource leveling

I picked A. precedence Diagramming method (PDM)
