One of the great things about diversity is that you get the benefits of different cultural viewpoints into your organization. People from different regions and countries approach problems differently. You and your team get exposed to different work styles, work ethics, and operational mindsets. This exposure will make you more appreciative of the different views your own customers have.
The problem with diversity is that highly diverse teams are more difficult to merge into a single organizational culture. The features of the organizational structure you are trying to build may be at odds with how some of your individuals approach productivity. Merging their cultural background into your team culture is hard but worthwhile.
Diversity is an asset, even when it makes some things more difficult. It is something to be embraced. It also means that you may need to spend more time ensuring that your culture is designed to embrace that diversity.
