A work project consists of twelve activities labeled through L. Upon being asked to specify the order in which the jobs had to be done, the manager answered as follows: A, B, and C are the first activities of the project and can start simultaneously and immediately; A and B precede D while B precede E, F and H. Activities F and C precede G while E and H precede I and J. The activities C, D, F and J precede K which, in turn, precedes L. Further I, G and L are the terminal activities of the project. Draw a network diagram corresponding to the project. [5]
