In the Production management course, my team of four studied the production of the Apple Watch 9 during the whole semester, and we presented our results every few weeks. The course also invited people from the industry, such as Audemars Piguet, to explain how production is managed in luxury watchmaking.

We first analysed the company: its suppliers, its value adding network, the flows of material and information, and the bill of materials of the watch. We then forecast the demand over 18 months with a Holt-Winters model, tuned to minimise the error on past sales. From this forecast, we built the aggregate plan, the master production schedule, the capacity check and the material requirements plan, and finally chose the inventory policies: economic order quantity, production quantity, discounts and safety stock.
