The Personal MBA

A glossary dressed as a course: it teaches vocabulary for judgment rather than judgment itself.

The Personal MBA, Josh Kaufman, 2010.

A glossary dressed as a course: comprehensive, well organized, genuinely useful as a reference. It teaches vocabulary for judgment, not judgment itself, and reads best next to a real decision rather than instead of one.

Kaufman argues a business reduces to five repeatable functions (creating value, marketing it, selling it, delivering it, and financing the whole operation), and that mastering the mental models underneath those functions matters more than a credential. The book compresses decades of other people’s frameworks, from Drucker to modern pricing theory, into one shared vocabulary, and positions that compression itself as the alternative to business school. Compression is not the same as insight, and the book mostly proves the first.

Two things. The five part definition of a business, used as a filter: value, marketing, sales, delivery, finance, and if an effort is missing one of the five it is a hobby, not a business, whatever else it resembles. And the convenience versus fidelity axis: nearly every improvement to an offering is really a decision about which of those two to sacrifice, since chasing both at once tends to produce neither.

Before pitching a new offer to my newsletter list I score it on an index card against the five parts: what the value is, who wants it, whether they will pay, whether I can actually deliver it, and whether the math clears my hourly rate. Six offers scored this way since spring. Two failed at delivery before I built anything, which saved roughly three weekends I would otherwise have spent making something I could not fulfill. One passed all five cleanly and still did not sell, because the card has no box for whether anyone had heard of me yet, a problem the book treats as solved the moment attention gets attracted, as though attracting it were the easy part.
