No one likes being dependent on someone else.
The essence of teamwork is that a group of people can come together and produce something greater than if they had each worked independently, the “whole is greater than the sum of its part” idea, but is a supply chain actually “teamwork”?
Perhaps this is pessamistic, but on first glance, a supply chain seems like a necessarily risky environment to work on. The idea that your performance, indeed, your job, is hinged on the ability of someone else to perform adequately is a thought I’d probably find dangerous to wake up to every morning. Don’t get me wrong, its not like other areas of business lack dependencies or aren’t qualifiedf by them, but the very notion of “supply management” is linked with the interaction and dependency, unlike, say, marketing or accounting. A marketing team, from my limited understanding, would probably be required to work closely with each other to achieve a common goal, and they are all dependent on one another, but they are bound by the fact that they will all be regarded and assessed equally on their result.
A supply chain manager is judged on his end whether or not someone else did their job correctly. A rather scary idea.
