I think that any change in the process is an improvement. Yes, including the change that brings bad results. If executed properly, with the failsafes in place, negative part can be mitigated.
What is important, is the decision to make a change, and commitment to it.
Not every change will bring the intended benefit, but the overall improvement through experimentation and openness is well worth it.
Don’t attempt it in the organisation that does not allow for failure, though - unless you would like to change jobs.
