According to Alan Robinson and Sam Stem, what can organizations do to encourage serendipity?

A) Provide extrinsic motivations
B) Recruit employees with large "C" type creativity
C) Encourage experimentation
D) Organize more official activities

According to Alan Robinson and Sam Stem, organizations can encourage serendipity by encouraging experimentation. This involves giving employees the freedom to try new things, take risks and make mistakes, which can lead to unexpected and valuable discoveries. Providing extrinsic motivations or organizing more official activities may not necessarily lead to serendipitous discoveries, while recruiting employees with large "C" type creativity may not be practical or feasible for all organizations.
