Building Multiply: Eleven Ways to Be Wrong

Founder & CTO Oskar Boëthius Lissheim on the panel of adversarial lenses he runs over every spec before writing code — eleven ways to catch the wrong plan before it ships.

Our founder and CTO, Oskar Boëthius Lissheim, just published the latest instalment of his "Building Multiply" series, this time on the panel of adversaries he runs over every spec before writing a line of code. We've adapted it below. Read the original on LinkedIn.

A flawless build of the wrong plan is still the wrong plan. So before any code, Oskar runs a panel of adversaries over the spec: eleven lenses, each hunting a different way to be wrong.

From five lenses to eleven

The panel started with five, in the spirit of Jeffrey Emanuel's approach. It grew by interviewing its own candidates, eventually settling on eleven distinct ways a spec can be wrong.

This is part of an ongoing series on how we build Multiply. Read Oskar's full essay on LinkedIn.
