McKinsey : Unleashing the power of small, independent teams
Small, independent teams are the lifeblood of the agile organization. Top executives can unleash them by driving ambition, removing red tape, and helping managers adjust to the new norms.
What does it take to set loose the independent teams that make agile organizations hum? These teams are the organizational units through which agile, project-based work gets done. The typical agile company has several such teams, most composed of a small number of people who have many or all of the skills the team needs to carry out its mission. (Amazon CEO Jeff Bezos contends that a team is too big when it needs more than two pizza pies for lunch.) This multidisciplinary way of composing teams has implications for nearly every business function. Take IT management. Instead of concentrating technology professionals in a central department, agile companies embed software designers and engineers in independent teams, where they can work continually on high-value projects.
