Apple - Organized by functional rather than divisional organization

... at Apple, we defied business orthodoxy by being a functional rather than divisional organization. Meaning we were organized by product focus like a much smaller company, rather than in discrete business units like some the size of IBM or General Motors. It certainly staved off the complexity of duplication that continues to plague other companies.
