Why are CPM, GERT, and PERT not considered sufficient to create a project schedule?

A) All three are tools and techniques of schedule development, not the actual schedule	B) As mathemetical analysis tools, they simply provide the dates that are posible, and do not consider resource pool limitations
C) They are sufficient. Each calculates early and late start and finish dates for each activity	D) They are Monte Carlo techniques used to provide what-if analysis for adverse external factors on a project

Answer & Explanation Answer: B) As mathemetical analysis tools, they simply provide the dates that are posible, and do not consider resource pool limitations

Explanation:

Answer A is tempting because it is true by definition, but Answer B is correct because it properly answers the question, in that these techniques do not take into account resource pool constraints. Answer C is incorrect because it provides possible early and late start and finish dates, but not the actual schedules. Answer D is incorrect because none of the the three are simulation techniques.
