The Scrum Field Book

This is a “sequel” to the Scrum book. The main highlight is regarding decision latency.

We can at most use 1 hour to make decisions. If it takes more than 5 hours, the project is going to fail.

To make that possible, we need to:

1. empower the right person to make the decision
2. keep rules to a minimum so that there is enough structure to ride the chaos

Other notable highlights:

Rules should fight for their lives

They make sense at the time when the rule was made, but it may no longer make sense.

Speed matters, everywhere
