I am a supply chain professional since 1998. In wikipedia the meaning of supply chain professional is explained as "people who coordinate production among multiple providers, ensuring that production and transport of goods happen with minimal quality control or inventory problems." In my defense supply chain management is mostly planning and problem solving. As a matter of fact, you may think "If I plan then there will be less need for problem solving". Maybe to some extent that is true, but to be honest if you are in supply chain management, you should always plan very well, and never stop expecting the unexpected! The unexpected pitfalls happen, and that's where you grow and shine with your problem solving skills.
