Katie Hope, reporting for BBC: Three years ago, Swedish software consultancy Crisp decided that the answer was no. The firm, which has about 40 staff, had already trialled various organisational structures, including the more common practice of having a single leader running the company. Crisp then tried changing its chief executive annually, based on a staff vote, but eventually decided collectively that no boss was needed. Yassal Sundman, a developer at the firm, explains: "We said, 'what if we had nobody as our next CEO -- what would that look like?' And then we went through an exercise and listed down the things that the CEO does." The staff decided that many of the chief executive's responsibilities overlapped with those of the board, while other roles could be shared among other employees. "When we looked at it we had nothing left in the CEO column, and we said, 'all right, why don't we try it out?'" says Ms Sundman.
