Project Management in Practice

1. Project Management in Practice Allocating Resources to the Project

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

3. Crashing A Project c=6 f=8 a=7 d=4 b=6 g=5 e=9

4. Ex: Table 6-1, Crashing A Project e=3 b=2 c=2 a=3 d=4

5. Ex: Table 6-1, Crashing A Project e=3 b=2 c=2 a=3 d=4 e(-2) a(-1) d(-1) Dur 5 Alternatives: e(-2) d(-1), from incremental, Proj cost = 220+70+30=$300 e(-2) a(-1) d(-1), from original, Proj cost=120+70+40+30=$260

6. Ex: Table 6-1, Crashing A Project e=3 1 b=2 c=2 a=3 2 d=4 3 Dur 4 Alternatives: e(-2) a(-1) d(-1), from incremental, d(-1), b(-1), Proj cost=260+30+60=$350 a,b,e fully crashed this is as far as we can go we cannot get the project duration under 4

10. Example (21 days, baseline) AOA c6 2 4 a6 f9 1 d7 6 b7 3 5 g7 e5

11. Example (21 days, baseline) AOA Using Excel Solver c6 2 4 a6 J8 f9 B17 B19 1 J11 J6 d7 6 J9 J7 B21 b7 J12 J10 3 5 g7 e5 B18 B20

12. Example (21 days, baseline) AOA AOA Event Time for a node: Time when all preceding activities are complete. Timewhen all preceding activities are complete. Max time of paths to node (if more than 1 path), or If one path to node, it is equal to the time to the node. Using Excel Solver c6 2 4 a6 J8 f9 B17 B19 1 J11 J6 d7 6 J9 J7 B21 b7 J12 J10 3 5 g7 e5 B18 B20

13. Example (21 days, baseline) AOA Using Excel Solver

14. Example (21 days, baseline) AOA Node Constraints: 2) 3) 4) 5) 6) Solution (amount to crash each activity) must be integer and >=0: Event Times must be >=0: Activity crash amount must be <= their max: Node 6 (all activities complete) must be <= Project Deadline: Using Excel Solver

15. Example (21 days, baseline) AOA Using Excel Solver

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

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