You will be best served by doing this exercise by hand. For two questions, please provide clean and neat diagrams, clearly labeled, with short, well-worded answers to each question.

Question 1:

Draw a project network diagram from the following information. What is the expected duration of the project?

Activity	Predecessor	Duration (weeks)
A	None	2
B	A	4
C	A	3
D	A	2
E	B	3
F	C	6
G	C, D	5
H	E, F	6
I	G	5
J	F, G*	4
K	H, I, J	5
L	K	1

* Work on activity J can begin any time, but cannot be completed before F &G are complete (in other words, this represents a Finish-to-Finish relationship with F and G).

Question 2: Suppose that the project in Question 1 of Exercises #2 is staffed by four team members: A manager (MGR), a designer (DES), an Engineer (ENG), and a Technician (TECH). The activities require the following staffing:

Activity	Staff Required*
A	MGR, DES, ENG, TECH
B	DES
C	ENG
D	TECH
E	DES, ENG (requires 50% of each employees time during this activity)**
F	ENG
G	ENG, TECH (requires 50% of each employees time during this activity)
H	DES, ENG
I	TECH
J	TECH (ENG and/or DES can complete up to 50% of the work)
K	DES, ENG, TECH
L	MGR

*Unless otherwise noted, all activities assume 100% time dedication of the assigned employee(s).

**When multiple resources are listed, those resources are required for that activity at the same time.

Create a histogram for each of the three employees (not MGR) to show the demands on their time.

Please help and thank you!
