The problem with OKR and every other fad managment system weather it be agile. SaFE, or LEAN is that they are all essentially cargocults once the leave the orgnisation that spawned them.

The problem is that organisations that feels the need to import management dogma's are trying to avoid doing the hard and potentially ego-destroying for upper management task of examining why they arent getting the performance from their mid management they want, by simply copying in the surface aspect of someone more succesfull,

Add to this that there is a surpricingly small number of people both in management and programming that have ever managed a project from cradle to grave at all let alone done so successfully and you get a culture of management consultants that have never been with a project long enough to watch the pretty facade crumble diue to a lack of solid foundations.
