Evangelists shouting at the top of their lungs that "you too can get what RCM offers... but without RCM!"
This particular brand of evangelism had its genesis in the 1990's.
Back when team-facilitated RCM was seen as the only way to implement RCM, and organisations were shedding human resources to try to keep up with competition as trade barriers dropped all over the world.
The evangelists (those promoting derivative methods like streamlining or rationalisation) turned their gaze on the method, instead of the implementation.
And the results have been dramatically, and almost universally, terrible.
