Ask employees

In 2013 there was a lot of controversy regarding allegations of abuse against several members of the Miami Dolphins professional football team. As part of the NFL (National Football League) investigation into these claims, a report was put together analyzing the behavior of the players. This report was primarily based on emails, text messages, and more than a hundred interviews conducted with the Dolphins personnel.

In 2002 the founders of Google attempted to set up an organizational system without managers. After just a few months, however, their system fell apart. Following this, the founders decided to use the failed experiment to determine which characteristics are the most important for strong leaders.

To find these characteristics, the founders considered not only the factual details from the failed system, but they also relied heavily on such things as employee surveys and double-blind interviews.
