Paper Mate Inc. is developing a more comfortable mechanical pencil named the Squishy Grip. Listed below is the work-breakdown-structure for the research and development processes at Paper Mate Inc. Map of the PERT/CPM model and determine the critical path and the number of days to complete the project. In addition, determine the probability that the project will be complete in 45 days, 50 days, and the number of days at the 85^th percentile.

ACTIVITY IPs TIME

OPT. MOST PESS.

A NONE 6 8 10

B NONE 4 5 6

C NONE 1 2 3

D A 8 18 28

E C 4 5 6

F B,D,E 7 8 9

G B,D,E 2 5 8

H F 12 13 14

Furthermore, each activity along the critical path can be crashed by 2 days. The crash cost per day starts at $100.00 (cheap) for the first activity of the critical path and increases to $500.00 (expensive) for each of the additional critical activities. Determine the best crash strategy if the R&D project needs to be completed 3 days early.

Then submit a 2 Paragraph project report to your boss the V.P. of R&D, Mr. Daffy Duck summarizing all your PERT/CPM results.

Answer for Question One

Map of the project with the completion time and critical path clearly displayed:
