Category Managers work for procurement within the supply chain. Their title is often confused with the position of the buyer. Generally working for retail, category managers are responsible for procuring certain goods falling under a particular category.
As a Category Manager, your job will entail sales and marketing activities, apart from making sure the right products are available on the sales establishment's shelves. You will contribute to creating the retail strategy for the category of goods in your section.
Getting up to speed on whatever your competitors are doing will be a big part of your job, kind of like a spy or a detective. You will not only have access to market research and benchmark data, but you will also gain insight into the overall finances of your company and the legal terms.
