Given the following project to landscape a new building site.

Activity Immediate Predecessor Activity duration(days) Resources used

A: Get Plants - 2 X,Y
B: Get flowers A 2 X
C: Obtain soil A 3 X
D: Obtain Fertilizer B,C 4 X,Y
E: Select Labor D 3 W,X
F: Set date D 1 W,X,Y
G: BEGIN E,F 2 X,Y

(a) Determine the critical path and project duration in days.

(b) Given that each resource is assigned 100% to each task, identify the resource constraints.

(c) Level the resources and determine the new project duration and critical path

(d) Find what alternative solutions can be used to shorten the project duration and not over-allocate the resources.
