Refreshed and updated PowerPoint resources aimed at assisting teachers with the delivery of the CAIE (9609) A-level Business specification. These slides are designed to support the delivery of 4.2 Inventory Management. The presentation starts with an examination of the purpose of inventory (raw materials, work-in-progress and finished goods), before then considering the costs and benefits to a business of holding inventory.  It then examines simple inventory control charts, including a look at buffer levels, lead times and re-order levels.  The importance of supply chain management (SCM) is then analysed in detail before it moves on to consider the impact and implications for a business of both just in time (JIT) and just in case (JIC) inventory management systems.  The slides contain the Quick Fire Five questions and also a practice essay (both with solutions).
