It is important to note that rule number one of OKRs is that… there is no rule number one! OKRs are the first truly crowd-sourced methodology. There is no one rugged prairie agency or thought leader that has created and commands what can and cannot be done around OKRs in business.
There is no one thought leader that developed OKRs. Sure, John Doerr wrote a book named “Measure What Matters” which has greatly popularized OKRs, but he's clear that he did not come up with the concept. As such there is no one to form and refine new ideas as they come to the space.
In addition, the dilemma is that John's book was not intended as a” how to” and therefore has proven very difficult for most organizations to follow and most software vendors to enable. In reality, there is no one source to say any of these ideas are right or wrong.
Further complicating the problem is that it appears that most of the OKR software Developers lack industry and real-world business experience. This has resulted in a cluster of tools that either try to replicate the stories from John Doerr’s book or merely copy what the other software vendors are providing.
