MS Project Exercises Exercise 10.20 Suppoudly have a complete activity predecessor table below and we Mish to create a network diagram highlighting the activ- ity sequence for this project. Using MS Project, enter activities A through E, their durations, and their predecessors. Note that all duration times are in days. Predecessors Activity A B Project: Remodeling an Appliance Duration Conduct competitive analysis 3 Review field sales reports 2 Conduct tech capabilities assessment 5 Develop focus group data 2 Conduct telephone surveys 3 D A, B, C D E ANSWER QUESTION 10.21 s 381 Predecessors Activity F Duration 3 E G H F G H 1 - im Identify relevant specification improvements Interface with marketing staff Develop engineering specifications Check and debug designs Develop testing protocol Identify critical performance levels Assess and modify product components Conduct capabilities assessment Identify selection criteria Develop RFQ Develop production master schedule Liaise with sales staff Prepare product launch 3 2 6 12 3 L M N 0 P Q R 4 5 LK 1 M M NO P Q 1 3 Exercise 10.21 Now, continue developing your Gantt chart with the rest of the information contained in the table in Exercise 10.19, and create a complete activity network diagram for this project Exercise 10.22 Identify the critical path for the project shown in Exercise 10.19. How can you identify the critical path? (Hint: Click on the "Tracking Gantt" option.) 10.25. Dummy variables are used in what kind of network dia- gramming method? a. AON b. Gantt charts d. OBS 10.26. Suppose you evaluated the best-case, most likely, and worst-case duration estimates for an activity and deter- mined that they were 3 days, 4 days, and 8 days, respec- tively. Using PERT estimation techniques, what would be the expected duration for the activity
