The three advantages do not act in isolation; they feed a cycle. Because the model is easy to try, more people try it. Because more people use it, there is demand for tooling — templates, calculators, shared conventions — that lowers the effort of use further. Lower effort brings in still more users, including people who would never have built the model themselves. The cycle also works on the supply side: as the model becomes a shared reference point, results expressed in its terms are easier to compare across teams, which makes it more attractive still. This is why the model now functions as a default starting point within its scope rather than one option among many.

Those three advantages don't sit apart. They feed each other. The model is cheap to try, so people try it. Enough people try it, and someone builds a template, a calculator, a shared convention for reporting the result.
