Case frameworks
Firms disagree in public about frameworks, and these guides quote that disagreement rather than resolving it for you. One firm prints that you should avoid forcing a solution into a standard structure; another recommends economic frameworks by name in its own focus areas. Each guide takes one framework, shows it working on real numbers, and marks the point where it starts producing a tidy answer to the wrong question.
