What it is: Gaining a clear distinction of what we are choosing to do

When to use it:

When working in larger groups with many perspectives (or throughout your own individual process to feel clear-headed)
When you have leadership reviews
When there are multiple good options (and so you’re at risk of second-guessing yourself later)

How to use it:

Document what it is you are deciding between, and why it is you are choosing one option over another
Capture the alternatives for future reference
Include the types of signals that would make you reconsider / go with a different direction

This works great with

Assumptions map - as you make design decisions, it will help unearth assumptions and hypotheses you are making in choosing specific design details
