Do you agree with this explanation of a merchandiser's job?
The overall description of what a merchandiser does is to “track and analyze market trends, production costs, and previous sales numbers to determine the product direction that the manufacturers will take each season” (Fashion Schools). They would also spot trends and develop line assortments. At a large company like Levi’s the merchandiser would have a much more focused role. Depending on their exact title they may only work on trend development and assortment planning or they may only work on production or they may only track the sales. Larger corporations have more people meaning the scope of responsibilities for each person is very narrow. Whereas at a start-up the merchandiser may be the only person at the company doing that job and will do everything associated with merchandising from planning, trend spotting, visually merchandising the store to working with factories on production, samples and fit.
The one thing that I would find to quibble with here is that I believe that you are leaving out a part of the merchandiser's job. I would argue that a merchandiser also has to do a lot (of course, as you mentioned, this depends on the exact title of the job and the size of the company) on figuring out how to sell the lines that are decided upon. In other words, it seems to me that your explanation focuses only on the decision about what to make, not the decisions about how to sell what is made. Merchandisers tend to be heavily involved in making decisions about how to present the product to the consumer, not just in deciding what product to offer.
Therefore, I think that you should talk some about that end of the job. I think you should talk about things like promotional campaigns and techniques since those can be part of a merchandiser's job.
