(Potential causes ofprocurement problems) Logan Logging Company began imple¬ menting a just-in-time inventory system several months ago. The production and purchasing managers, however, have not seen any dramatic improvements in throughput. They have decided that the problems are related to their sup¬ pliers. The suppliers (there are 3) seem to send the wrong materials at the wrong times. Prepare an oral discussion of the problems that might exist in this situ¬ ation. Be certain to address in your discussion the following items: internal and external communications; possible engineering changes and their impacts; num¬ ber, quality, and location of suppliers; and length of system implementation.
