The Salmon or the Chicken: How Do You Make Up Your Mind?
•
1 like•530 views
This document discusses managing uncertainty in software development projects. It explores how to make decisions without full knowledge of what will be needed or what will change. It advocates deciding based on what is "correct enough" and "not painful", rather than attempting to eliminate all uncertainty. It also suggests delaying decisions to the last responsible moment and accepting that requirements will inevitably change in unknown ways. The overall message is that great software results from making incremental decisions to progress while releasing frequently for feedback, rather than trying to predict and plan for all future changes upfront.

- 42. If you want to make great software ... you don't do it by attempting to make each decision great. You make decisions that get you over the line ... then you release, get feedback, and keep doing it again.
