Essentially, any company may constitute appropriate case study material. The important factor when choosing a business to discuss is the ability to effectively link the case study to the point(s) that you are making so that you can support it. Choosing the business that suits a particular topic/question the closest but not being able to effectively elaborate on information relevant to that business in an advantageous manner (i.e. in a way that further increases the quality of your response) is not sufficient for favourable performance.
With that being said, you could discuss the following businesses for each topic and subtopic:
- Role - McDonald's, Qantas
- Influences - McDonald's, Qantas
- Processes - McDonald's, Domino's
- Strategies - McDonald's
- Role - Apple
- Influences - Mcdonald's, Apple
- Processes - Samsung
- Strategies - Apple, Samsung
- Role - McDonald's, Apple
- Influences - McDonald's
- Processes - Apple, Bingo Industries, BMW
- Strategies - Apple, Harvey Norman
- Human resources
- Role - McDonald's, Qantas, JB Hi-Fi
- Influences - Google
- Processes - McDonald's
- Strategies - Google
- Effectiveness - Google, JB Hi-Fi, McDonald's
You may already have relevant case study material targeting some of these businesses. If this is the case, then great! All that would be left would be to maximise your ability to effectively incorporate case study information into your responses. If you wish to discuss one (or more) of these businesses but are not currently equipped with knowledge of relevant information, it would be a good idea to research each business with respect to the particular syllabus dot point that you are covering.
I hope this helps!
