2020 Scrum Guide: Summary

🔥 Scrum Definition

Scrum is a lightweight framework that helps people, teams and organizations generate value through adaptive solutions for complex problems.

Scrum requires a Scrum Master to foster an environment where:

A Product Owner orders the work for a complex problem into a Product Backlog.
The Scrum Team turns a selection of the work into an Increment during a Sprint.
The Scrum Team and its stakeholders inspect the results and adjust for the next Sprint.
Repeat

Scrum Team is the one team (no separate Dev Team within Scrum Team).
Introduced Product Goal for Product Backlog, that aims to align Sprint Goal (Sprint backlog) and Definition of Done (Increment) with the Product Goal.
Scrum team decides how to measure own progress towards the Sprint Goal (now Guide is less prescriptive about it).
Three artifacts have corresponding commitments: Product Goal for Product Backlog, Sprint Goal for Sprint Backlog, DoD for Increment.
Sprint Goal is more focused on bringing and communicating value to stakeholders

Empiricism (decisions are made on empiric knowledge) and Lean thinking (reduce waste + keep focus).

Scrum Team = Cross functional team (includes designers, QA, and others - not only Developers).

Scrum uses iterative, incremental approach to optimise predictability and to control risk.

Empirical Scrum pillars of

transparency (via artifacts - Product Backlog, Sprint Backlog, Increment, transparency enables inspection),
inspection (via regular five events - sprint, sprint planning, daily scrums, sprint review, sprint retro; inspection enables adaptation),
adaptation (regular adjustments based on results and progress towards goals).
