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 4.1 The Nature of Operations. The presentation starts with an examination of the transformational process, the role of factors of production and the ways of adding value to products via the operations function.  It then examines efficiency, effectiveness, labour productivity and sustainability, including the calculation of labour productivity and ways of improving levels of productivity within a business.  Next capital and labour intensive operations are assessed before the presentation concludes with a detailed look at the various operational methods of production including: job, batch, flow and mass customisation.  The slides contain the Quick Fire Five questions and also a practice essay (both with solutions).
