The biggest challenge faced in the last job, I would say it was very difficult to get some cohesive information about delivery dates for products that we needed for manufacturing. I had discovered that we had two different sets of lead times that had gone unnoticed and so they had not known why they were planning certain things and things weren't coming in when they were supposed to. So I identified it and the challenge was that one of my coworkers tried to prevent me from speaking to people about it even though it was part of my job and was part of a request from my manager. So I continued to outline, here's the information that you need, here's the possible things that it can affect and they actually launched an investigation into it and a small task force to try and correct how things were appearing in the system.
