Mental Models for Product Designers
summary
A product designer at Dropbox develops a printable cheat sheet of seven starter models that claim to make decision‑making, problem solving and communication more reliable. Models include first principles, inversion and abstraction laddering for problems; a hard‑choice grid and problem‑solution‑confidence for decisions; and a quick what so what now what and diamond structure for communication. The cheat sheet sees use in a Dropbox file‑recovery project, in mind‑mapping software, and in support‑agent brainstorms.
