None of these models/frameworks work very well if people don’t consistently train to handle responsibility and dissonance (mental, physical, spiritual). This is the critical thing. You don’t want ‘safe’, you want extensible. People need to build their strength and endurance to deal with adversity — apart from poor business models, this is why orgs struggle. Reorganizing companies or reinventing their business operations is not a ‘safe’ practice (I get that you probably aren’t using ‘safe’ in this regard, but it is still a point worth making). Holacracy, for example, from my experience, has serious limitations in this regard — how constitutional amendments manifest, shifting roles, how leadership can be redistributed, etc.
