Please review the attached for assistance with supply chain and location planning.

---
Construct an "analysis of the division's operations and produce a plan to improve operations with an eye for reducing costs."
Summarize recommendations in a paper. Include thoughts on the "laundry list" below.

1. Should production remain in Mexico or be brought back to the US?
a. If so, where would you recommend?
b. Should only part of the production be brought back to the US?
c. Should production be shifted to Asia (China)?

2. Should the product distribution network be changed?
a. Production in Mexico, central warehouse (NAW) in St. Louis, regional distribution centers in Pennsylvania, Georgia, Texas, Colorado, California
b. Close NAW, ship from Mexico directly to regional distribution centers listed in letter "a" above
c. Close NAW, create a new central warehouse in Texas near the Mexico plant, ship to regional distribution centers in letter "a" above (with a distribution center in St. Louis/Chicago region)
d. Close NAW, create a new central warehouse in Texas near the Mexico plant, ship directly to customers.
e. Hire a professional distribution company to handle distribution.

3. Should the St. Louis Customer Service staff be decentralized to the regional distribution centers listed above?

4. Can the sales forecast process be improved? If so, how?
