For example, all of the above examples could fit into business rentals and non-business rentals. To recap, not all preparation for case interviews is created equal.

Sheppard defined design as "understanding the needs of your users, then creating products and services that meet those needs". Design professionals have long understood the value of design, Sheppard added, but have lacked the quantitative and qualitative data to back up their views and convince senior management.

McKinsey has responded by building a design-consulting division of over people, including employees of California design studio Lunar, which the consultant acquired in , and Swedish studio Veryday, which it bought in The Business Value of Design report contains insights from five years of research, which has been distilled into a metric called McKinsey Design Index, which will be launched online next month.
