Hi Anonymous! As always, just use pure logic to disaggragate the ACTUAL question!
"What are key drivers of market growth?"
1. Market growth is defined as the yearly percentage change in total market size (revenues)
2. Revenues can be disaggragated into Volume and Price
3. Volume growth is driven by changes in market demand (number of customers, average demand per customer) and market supply (production capacity, logistics capacity, etc.)
4. These elements can be further disaggregated into drivers (e.g., expected growth in number of customers can be driven by demographics, macro trends, shifts in preferences, etc.)
You can (and should) outline this logic by means of a logic tree. As any case question, mastering first principles of problem structuring will allow you to come up with the answer to this specific question.
