Question

Consider the portfolio of projects described in the table. The resource requirements are in numbers of labor hours. The Greatest Resource Utilization rule would begin work with project:

Project	Date Rec'd	Date Due	Resource 1	Resource 2	Resource 3
A	Apr 2006	Oct 2006	200	0	400
B	Feb 2006	Sep 2006	150	200	170
C	Mar 2006	Aug 2006	0	250	200
D	Jan 2006	Nov 2006	150	100	0

Options:

A.

B.

C.

D.

Answer 1

Here the resource requirements are in labor hours. Hence the resource utilization is labor utilization.

Labor utilization can be found as labor hours per month, by dividing the total labor hours with the number of months for a particular portfolio

The project details are:

Project	Date Rec’d	Date Due	Resource 1	Resource 2	Resource 3
A	Apr 2006	Oct 2006	200	0	400
B	Feb 2006	Sep 2006	150	200	170
C	Mar 2006	Aug 2006	0	250	200
D	Jan 2006	Nov 2006	150	100	0

Hence the total duration (in number of months), total resource (in labor hours) and labor utilization (in labor hours per month) is:

Project	Duration (months)	Resource (labor hours)	Resource Utilization (labor hours per month)
A	6	600	100
B	7	520	74.29
C	5	450	90
D	10	250	25

Hence, according to the greatest utilization rule: Project A is the project with which one should start. This is because project A is taking the maximum time an employee should contribute hence maximizing their utilization.
