12. After graduation, you and several of your friends decide to start a new software company. As the vice president of operations, you are in charge of several production steps, including the process that records software onto a CD.

You have identified several activities that must take place before this “burn-in” process is ready to use:

a. (**) Draw the project network and calculate all ES, EF, LS, and LF times.

b. (**) Every week of delay in the project costs your company $3,000. Suppose you know the following:
(1) Activity G can be crashed by 1 week at a cost of $1,500, (2) Activity F can be crashed by 1 week at a cost of only $50, and (3) Activity H can be crashed by 1 week at a cost of $2,000. Should you try to crash the project? If not, why not? If so, how much money will the company save?
