I suspect other people have a better response to this? I think Andy Grove is correct — you can fact check that in John Doerr’s excellent book “Measure What Matters”. My emphasis is less about whether or not Doerr (or Grove) refreshed Peter Drucker’s original principle (management styles is not my jam) and more about the fact that these principles attract fans and practitioners because they are embedded with Primal Code (creation story, creed, icons, rituals, lexicon, nonbelievers and leader). That said, companies run by entrepreneurs and companies operated by managers are inherently different enterprises. Entrepreneurs are innovative and pivot, retrench or switch vision lanes without thinking about how to write it up or what to call it. Managers tend to need a style guide. (NOTE: I’ve heard that Googlers spend more time writing their OKRs than actually doing the work.) Maybe someone else can help answer? Thanks for bringing this up, Dan 🙏🏼
