2 Source: Adapted from James A. D. Stoner, Management, 6th ed. (Upper Saddle River, NJ: Pearson 1995).
- a. Draw a network diagram for the project.
- b. Mark the critical path and state its length.
- c. If the Tesla 6 had to be completed 2 days earlier, would it help to:
- i) Buy preassembled transmissions and drivetrains?
- ii) Install robots to halve engine-building lime?
- iii) Speed delivery of special accessories by 3 days?
- d. How might resources be borrowed from activities on the noncritical path to speed activities on the critical path?

Draw a network diagram showing the linkage between these activities from start to finish. For the diagram, each activity should be labelled alphabetically ie. A, B, C… etc.
PERT Formula:
TE = (O + 4T + P) / 6
TE = Pert Expected Time Duration,

- The Virginia Department of Transportation is undertaking aconstruction project to widen a large section of interstate, highway near Washington, DC, which includes the construc-tion of a number of new bridges, interchanges, and over-passes. The first step in the project is the appointment of a project manger and the development of a project team, someof which will be departmental employees and others will beprivate consultants and operatives. The team for a project thissize also requires a large support staff with varying technicalskills. Once the team is selected and the staff is in place the first task is to select a primary contractor to manage and over-see the actual construction.

Each piece of architecture depicts its time, history, and style. It shows how far humans have gone and how brilliant our minds can build something complex out ofscratch. From past to present-day architecture, it signifies uniqueness and creativity thatmade them remarkable. Today’s architecture requires modern materials to beaccurate and sustainable.With that remark, Bio Industries is proposing Bio-Bricks.
