The Scrum Guide was last updated on Nov 2020. I hope this helps others learn and study for their certifications. I hope to pass on some of the value of my learning to others wishing to change careers and learn.

Scrum is a lightweight framework that helps people, teams and organizations generate value through adaptive solutions for complex problems. In a nutshell, Scrum requires a Scrum Master to foster an environment where:

1. A Product Owner orders the work for a complex problem into a Product Backlog.

2. The Scrum Team turns a selection of the work into an Increment of value during a Sprint.

3. The Scrum Team and its stakeholders inspect the results and adjust for the next Sprint.

4. Repeat

Scrum is founded on empiricism and lean thinking. Empiricism asserts that knowledge comes from experience and making decisions based on what is observed. Lean thinking reduces waste and focuses on the essentials.

Scrum employs an iterative, incremental approach to optimize predictability and to control risk. Scrum engages groups of people who collectively have all the skills and expertise to do the work and share or acquire such skills as needed. Scrum combines four formal events for inspection and adaptation within a containing event, the Sprint. These events work because they implement the empirical Scrum pillars of transparency, inspection, and adaptation.
