For large projects that involve several hundred people performing various activities over several years, it is practical to have each person estimate activity durations at the beginning of the project.

True or false?

False

Explanation:

It is very Impractical to have each person in such a project estimate activity durations at the beginning of the project.

Firstly there are several hundred people involved and it is a very large project, each and every person cannot begin to guess how long activities will take because the plans will have to fit into the next person's plans. It is impractical.

Also, it is a Long Term Project where people will perform different roles over those years. It is impractical for each person to estimate how long their activities will take to complete again because such plans would have to be interwoven with the next person's.
