What AI already does of a BA's job

Published July 6, 2026

A coverage matrix: around 50 business-analysis techniques from Wiegers and BABOK v3, each one scored honestly on how much an AI assistant covers and what's left to the human. Five levels from "Full" to "None," with a clear scale. Bottom line: roughly 58% of a BA's formal tasks are already meaningfully automated, and only about 10% stay purely human.

Prompt · guide

Reviewing a site through synthetic users

Published June 25, 2026

A ready-made prompt: runs any live page - landing page, pricing, a form - past 5 fictional but realistic users from your audience. Each one reads top to bottom and says what caught their eye, what was confusing, and where they'd close the tab. Output: a verdict by section and a top-5 list of copy fixes. Calibration before you show it to real people.
