How the schema of a TCF was conceived

I find the project quite interesting and brilliant, but I think it would be interesting, at least to me, know you come out with the current schema of the TCF.
I would really like to know the process that brought to define the chain Problems -> Mission -> (Narratives) -> Goals -> Challenges -> Strategies —> Projects -> Journal. How did you find this chain? Was it empirical? Was it based on researches about human beings?
In addition, how do you test it? How do you know that the schema is a good one and you are not missing something?
Thank you in advance

Start by reviewing the TCF schema and the Problems -> Mission -> (Narratives) -> Goals -> Challenges -> Strategies -> Projects -> Journal chain described in the issue. Clarify the historical or research basis for the schema and how it is evaluated, then document the rationale and testing approach in a contributor-facing location identified by the maintainers.
