QUESTION 2 The following information is given for a project:

Project

Activity	Predecessor	Duration	Workers needed each day
A	-	4	5
B	A	4	4
C	A	2	2
D	B, C	4	1
E	C	2	3
F	C	4	2
G	D;E;F	3	3

a) Draw the network. How long will it take to complete the project? Identify the critical activities and critical line(s)/path(s). Which activities have slack (float), and how much?

b) Develop a Gantt-chart and a resource table for the project where the activities start as early as possible. Mark the critical activities in the Gantt-chart. In the resource table summarize how many workers are needed each day.

c) Assume that the project has access to maximum 6 workers each day. How will this resource limitation affect the projects schedule?

d) Disregard the information in question c). Assume the projects duration needs to be crashed/reduced by 3 days, but with the lowest costs possible. Activity A can be reduced by 1 day and it will cost 8000. Activity B can be reduced by maximum 2 days and each day will cost 4500. Activity D can be reduced by 1 day and it will cost 2500. Activity F can be reduced by 1 day and it will cost 3000. What is the new duration? Which activities will you crash/reduce and by how many days? Argue why. How much will this minimum cost? Find the critical path(s)/line(s) after the crashing.

e) Disregard the information in questions c) and d). Assume that each worker costs 1000 each day. Develop a table where you summarize the total costs each day and calculate accumulated costs each day. What is the total planned cost for the project (the total budget)?

f) The project is followed-up and controlled after 7 days. Then the following information is collected:

Activity	% Completed	Actual Cost
A	100 %	20000
B	80 %	14000
C	100%	4000
D	0	0
E	40 %	3000
F	30 %	2000
G	0	0

Find/calculate PC, AC, EV, CV, BV, SV, CPI, SPI, ECAC, and ETAC after 7 days. Discuss the development and status of the project after 7 days.
