acheiving deadline

Your project involves the construction of a flyover that is estimated to cost $1.5 Million. It has to be completed in 2.5 years. The project involves a new technology, on which neither the project resources nor you have worked in the past. As a project manager, you have done the best estimation, but some of the activities based on the new technology have shown negative slack during the execution process. If you do not complete these activities on time, the project finish date will get delayed. The sponsor informs you that the deadline has to be met, even though the project cost may be overrun. Out of the following, which will not assist you in achieving your deadline?

A) You crash the project by adding more resources

B) You define Start-to-Start and Finish-to-Finish dependencies among the task

C) You define more Finish-to-Start dependencies

D) A and B

 

Answer is given as C. Can someone explain

 Here question is which will NOT assist you in achieving deadline.

so this rules out A upfront, as A will result in faster execution. in result D also ruled out.

So now answer should be within B & C.

B talks about parallel processing which should help in getting work done faster.

so we are left with C

C talks about regular finish to start dependencies, which will not let you do parallel work and no chance of schedule crashing.So wont help in achieving deadline.

C. As FS is a sequential relationship.

Qsn'er's intension in this qsn is to  gaze  the understanding of  negative slack (float), and sequential relationships of activities:

but I think answer and options are not narrated correctly.

either there is vital missing  of concepts.

 

 Sir, The explanation is given as follows:

Correct Answer is 'C'. Defining more finish-to-start dependencies implies introducing more serial dependencies. This will not assist you in achieving your project deadline. All of the other options will help you to achieve the deadline by crashing (option A) or fast tracking (Option B).

 Is FF relation an example  of parallel activities. how it can be fast tracked parallely, when one is depends on other, it is only possible by crashing one /or both.

second thing w/o defining SF how you can approach to crashing.
