Project Management in Practice

Project Management in Practice Allocating Resources to the Project

Outline: • Expediting or Crashing a project • Resource Loading • Resource Leveling Homework: 20 (omit e) using MSP 21 (an AOA diagram may help!) by hand and Excel

Expediting A Project: Table 6-1, Example Project completion time = 21 days, cost $400, critical path = a-c-f

Table 6-1, Example (21 days, baseline) 6 or 4 days only 0 6 6 12 12 21 c6 f9 a6 5 7 12 21 0 6 6 13 d7 13 20 g7 7 14 0 7 7 12 14 21 b7 e5 2 9 9 14

Table 6-1, Example (20 days) 6 or 4 days only 0 5 5 11 11 20 c6 f9 a5 5 7 11 20 0 5 5 12 d7 12 19 g7 6 13 0 7 7 12 13 20 b7 e5 1 8 8 13

Table 6-1, Example (18 days) 6 or 4 days only c4 f9 a5 c (-2) a (-1) d7 g6 b7 e5 g (-1)

Table 6-1, Example (max) Fully crashed. Fully crashed. Crashed by 1. c4 f9 a5 d7 g6 b7 e5

Table 6-1, Example (max=16) Fully crashed. Fully crashed. Crashed by 1. c4 f9 a5 f7 d7 g6 g4 b7 e5

Project Cost versus Project Duration Example Table 6.1 $750 $650 $550 $470 $430 $400

Table 6-1, Example (21 days, baseline) AOA May be crashed 1 day at a time c6 2 4 a6 f9 1 d7 6 b7 3 5 g7 e5

Resource Loading • Amount of specific resources that are scheduled for use on specific activities or projects at specific times. • Usually a list or table.
