Using the example of Lego or another firm you are familiar with, describe how the company has had to change operational strategy in response to changes. Use the framework of either demand and supply uncertainty (efficient/responsive/risk hedging/agile) or the "working your assets to boost your growth" questions of who/what/how. (5-6 sentences should be enough. Explain what they were doing; what changed; why that was a problem if they kept business as usual; how they responded)
