We wondered when we started hearing this whether this would de- personalize of work and increase isolation and loneliness. When we asked people who live in this world if they felt that way, they looked at us like we were nuts. They are given more freedom and control over project once they are on the team. Fewer sign-offs and other bureaucratic controls. They are working on projects they are excited about and are proud of their accomplishments.
Work is an adventure, instead of a routine grind.
Another reason they don't feel isolated is they learn to work the system. Employees figure out how the team assignments are allocated and position themselves to join teams with colleagues they have worked with before. Some people have been on many teams with the same mix of people for several years. They create their own personalized network. This is great for creating a personalized culture.
