Scrum

Scrum Definition

Scrum Team (SC)

Developers

Product Owner (PO)

SM foster envorinoment where:

  1. PO orders work for complex problem into a Product Backlog (PB)
  2. ST turns a selection of work (Product Backlog Items, PBIs) into an Increment during a Sprint
  3. ST & stakeholders Inspect the results & Adjust for next Sprint
  4. Repeat

Scrum Theory

Empiricism: knowledge comes from experience

Lean Thinking: reduce waste and focus on essential

Scrum Approach

iterative, incremental approach
to optimize predictability and to control risk

the Sprint contains 4 formal events:

  • Sprint Planning
  • Daily Scrum
  • Sprint Review
  • Sprint Retrospective

3 empirical pillars

Inspecition:
The Scrum artifacts and the progress toward agreed goals must be inspected frequently and diligently to detect potentially undesirable variances or problems.

Adaptation
If any aspects of a process deviate outside acceptable limits or if the resulting product is unacceptable, the process being applied or the materials being produced must be adjusted.

Transparency

3 formal artifacts:

  • Product Backlog
  • Sprint Backlog
  • Increment

Scrum Master (SM)

A lightweight framework that helps people, teams and organizations generate value through adaptive solutions for complex problems

Scrum Values

Commitment

Focus

Openness

Respect

Courage

Each element of the framework serves a specific purpose that is essential to the overall value and results realized with Scrum

Rather than provide people with detailed instructions, the rules of Scrum guide their relationships and interactions.

Various processes, techniques and methods can be employed within Scrum

Scrum wraps around existing practices or renders them unnecessary

Scrum makes visible the relative efficacy of current management, environment, and work techniques, so that improvements can be made

ST is a group of people who collectively have all the skills and expertise to do the work and share or acquire such skills as needed

The emergent process and work must be visible to those performing the work as well as those receiving the work

Transparency enables inspection. Inspection without transparency is misleading and wasteful

The Scrum framework is purposefully incomplete, only defining the parts required to implement Scrum theory

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.
