As a programmer and someone who has started a small SaaS software business by myself. I can related to this comment. Programmer are the doers. They often pride themselves as the ones who are actually getting things done in an technology company.

This mentality often comes off to "those who manages or lead" as arrogant, and rightfully so. Often the doers don't see the bigger picture. For example, the relationships that is required to have individuals in an organization work together as a whole.
