Lesson 05: Agile Principles

We’re going to talk about the Agile Principles in this lesson.


2020 update notes

A few things have changed in the latest version of the Scrum Guide (2020), and the ASF exam is updated based on those changes. However, our videos are not updated yet; so, please note the following changes:

  • There’s no “development team” anymore, but only Developers.
  • The recommended team size is now “10 people or less” for the whole Scrum Team.
  • It’s now called “self-managing” instead of “self-organizing” (same concept, different name).
  • There’s a Product Goal now, which is part of the Product Backlog, and sets the overall direction for the product.
  • The Sprint Goal is now considered as part of the Sprint Backlog.
  • The concept of commitments is introduced for the artifacts:
    • Product Goal is the commitment for the Product Backlog.
    • Sprint Goal is the commitment for the Sprint Backlog.
    • Definition of Done is the commitment for the Increment.
  • The Definition of Done is created by the whole Scrum Team now, and not only by the Developers.
  • Now, any time you finish an item (based on the Definition of Done), a new Increment is formed. It’s not about having just one Increment at the end of the Sprint.
  • The guide doesn’t suggest 10% as the ceiling for the amount of time Developers spend on Product Backlog refinement.
  • Sprint Planning has three topics now:
    • Why? -> Sprint Goal
    • What? -> Items from the Product Backlog
    • How? -> Tasks created by decomposing the items
  • “Estimating” is now called “sizing”. So, it’s the responsibility of the Developers to size the Product Backlog items.
  • “Value” is no longer one of the mandatory attributes of the Product Backlog items. The mandatory attributes are description, size, and order.
  • Instead of calling the Increments “potentially releasable”, the new guide calls them “usable” (more or less the same concept).
