There is no reason why this theory should not work for any department. Try a department, then see what are your top sellers in that department.

Now select your department.

Here I used the stationery department. I put in 99 million in red for illustration. That is overkill - put in 100. I also selected a whole year as short periods can have significant fluctuations. We do not want to do this every week.

Now study the report to see your shop's strengths. See what do you sell. 

Now go to a major retailer's website and see how they categorize their department. Some like Amazon and the supermarkets have spent millions on this categorization, so they know something. Also, check out a few other shops. 

You now know the theory and your strengths, so layout your stock in a logical order.

Why not start now, pick a small department and see how you go?
