Some CEO of a successful company writes a book claiming his management wisdom led to his company success and then a bunch of CEOs read the book and try to replicate the same success because they don't have any original ideas themselves. In this instance the CEO was GE's Jack Welch and his policy was 'rank and yank'
Similarly, some CEO will write that you must have a mission statement and distill your management philosophy into 3 or 4 words preferably starting with the same alphabet. Next thing every CEO has their own tag lines: 'Agility, Accountabilty, Ambition' or 'Passion, Persistance, Performance' or <insert words from thesarus>. My previous company CEO spent thousands of dollars on polished metal tangram squares with her three words embossed on them given to every-single-employee at the company.
