<aside> 📕 Risk: Probability of a negative impact, weighted by how negative it is.

Reversibility: How easy is it to undo.

</aside>

Before doing something (like shipping code), we ask ourselves

• How much risk of having a very negative impact does it have.
• What's the probability that this action will need to be undone/changed.
• What is going to be the cost of undoing it. I.e. How reversible is it?

Low risk and easy to revert - “Two-way door”

Ship it! 🚢 - At Happy Scribe, we move fast.

High risk or difficult to revert - “One-way door”

This is very exceptional. In these cases, it’s okay to slow down.

1. Try to reduce the risk and/or increase the reversibility. For example, by writing tests.
2. Ask someone else to review your work.
3. Make sure to get the thumbs up from the rest of the tech team.
