compress the schedule

 The sponsor of the project you are managing asks you to compress the schedule.

Which of the following CORRECT?           

A crashing always shorten the timeline but often increases risk

B fast tracking often results in increased cost

C crashing is only a viable alternative if earned value analysis indicates that the project is ahead of schedule and under budget

D fast tracking will result in less parallel activities than crashing project

*****

Can some one pls validate/clarify the statements below,

Fast track also add (may/often) add cost, due to increased communcation / coordination required

As per PMBOK, Crashing the activities on the critical path saves time but Fast tracking any activities saves time (why so?)

 

A Wrong  : Crashing always shorten the timeline but increases cost not risk.

B wrong :  Fast Track always increase risk and re-work.

D wrong : Fast Track increases parallel activities, chance of more critical paths/near critical paths.

C some how acceptable, there is no other chance :

Reg Schedlue : If you Crash the schedule, that means schedule become shorten. in this case schedule is already ahead of schedule. then the schedule again ahead of schedule.

Example : The current  schedule is 2 weeks ahead.  If you crash 1 week then it becomes 2 weeks ahead.

Reg Budget : Current budget is under budget.  If you crash the schedule costs going to increse. 

Clarification: I

--Fast Track kills Project Managers Time that cost of money to the Projec. (Fast track also add (may/often) add cost, due to increased communcation / coordination required)

Crashing the activities on the critical path saves time because applying additional resources.

Ex: Activity A takes 20 days with 2 people.  If you add 2 more people the activity A may take 10+ days( + law of diminishing returns) .

Fast TRack : The activities need to run parallel that means the time of which activities doing parallel going to save.

Ex: Activities A, B,C and D takes each 5 days total duration is 20 days

If you do A and B activities doing FS relationship simultanious with C and D doing FS relationship.

The toal work completing in 10 days.

 

Answer is B...

 

A crashing always shorten the timeline but often increases risk> This is false as crashing increases resources and cost.

B fast tracking often results in increased cost> This is true as rework and risk ultimately increase cost.

C crashing is only a viable alternative if earned value analysis indicates that the project is ahead of schedule and under budget> Not true as we only crash the schedule to get back on schedule.

D fast tracking will result in less parallel activities than crashing project> Not true as we do activities in parallel as we don't have enough resources to do otherwise.

My final answer is B.

The example above explains how fast tracking can save time. When you do multiple activities simultaneously rather than consecutively, it will take less total time to complete. However, as previously stated, when you do fast tracking you incur risks like rework if coordination isn't well done. Thus there is an increased need for communication and coordination.

Well, I guess the right answer is option A the question you ask on http://college-paper-writing-service.reviews/ website. Because I think so that crashing always shortens the timeline and that the chances of risk factor are very few. So we may consider the option A which is correct. Please let me know! Thanks.
