Years ago I worked as a junior procurement officer at a medium sized Canadian manufacturing company. Within my first year, our production scheduler resigned and to my surprise, I was promoted to her position. I was terrified because I didn't have a background in operations management and I didn't understand its mysterious jargon. Acronyms like MPS, MRP, BOM, and the like were foreign to me. I also did not have a good grasp of our ERP system (SYSPRO).
