1. Draw the Network Diagrams for each situation
2. What is the critical path in each
3. Suppose you want to shorten the completion time as much as possible, and
you have the option of shortening any or all of B, C, D, and G each by one
week. Which would you shorten? Why?
4. What is the critical path and the earliest completion time based on your
analysis in #3 (above)? Explain your rationale.

Critical Thinking:
Objective:
Create a report that summarizes your Network Diagram and answers the four
questions listed above. Your explanations of the topics presented above as
requested by the R&D Department. You may insert a portion of an Excel
spreadsheet into your paper showing the critical path. Other software solutions such
as Power Point or Microsoft Project may be inserted into your paper.
TELL ME WHAT YOU HAVE LEARNED.
Requirements:
Successful Critical Thinking Exercise will be three (3) to five (5) pages in length and
incorporate the information and knowledge gained in the course addressing the
areas defined in the Case and Rubric.
