This document discusses several key Scrum patterns that can help teams deliver work more efficiently. It describes the "Yesterday's Weather" pattern which involves using a rolling average of past sprint velocities to determine how much work to pull into each sprint. The "Interrupt Pattern" is presented as a way to deal with unexpected interruptions by implementing a buffer. And the "Happiness Metric" pattern is introduced as a means to regularly measure team happiness and identify opportunities to improve engagement and performance.

Scrum Pattern: Yesterday’s Weather
As a Scrum Professional, I want to know more about the Scrum Pattern
Yesterday’s Weather so that I know how much work to pull into each Sprint

7. &
Pattern 1: Yesterday’s Weather
NOTE: To compute
Yesterday’s Weather,
take a rolling average
of the velocity for the
last 3 Sprints. Keep
recalculating
throughout the
release.

Symptoms
Demotivated team members
No working product (after 1 year)
Too many projects in-flights

10. &
• Work was pushed down to the
teams (~60 points per Sprint)
• Velocity not measured, no concept
of “Yesterday’s weather”
• Scrum Master didn’t use a Burn-
down chart
