Scrum History and Principles

Scrum Theory and Principles: The Empirical Foundation

Scrum is built on a solid theoretical foundation rooted in empirical process control - the idea that knowledge comes from experience and decisions should be based on what is observed. Understanding Scrum theory is essential for applying the Scrum framework effectively and passing the PSM-1 certification.

Quick Answer: Core Scrum Principles

PrincipleDescriptionApplication
EmpiricismKnowledge from experienceDecisions based on observation, not prediction
TransparencyVisibility of all aspectsShared understanding of work and processes
InspectionRegular examinationFrequent checkpoints to detect variances
AdaptationAdjusting based on findingsQuick response when issues are detected
Self-OrganizationTeams manage their own workTeam decides how to accomplish goals
Time-BoxingFixed time containersAll events have maximum durations

The Three Pillars of Scrum

Scrum is founded on three pillars that support every implementation of empirical process control:

1. Transparency

  • All significant aspects of the process must be visible to those responsible for the outcome
  • Requires a common language so all participants share understanding
  • The Definition of Done provides transparency on quality standards

2. Inspection

  • Scrum artifacts and progress must be inspected frequently
  • Inspection enables detection of undesirable variances
  • All Scrum events are designed for inspection

3. Adaptation

  • When inspection reveals that aspects deviate outside acceptable limits, adjustments must be made
  • Adjustments should be made as soon as possible to minimize further deviation
  • Empowered, self-managing teams adapt quickly and effectively

Why Theory Matters for Practice

Teams that understand Scrum theory can:

  • Make better decisions about how to apply the framework
  • Adapt intelligently when facing unique situations
  • Avoid cargo cult Scrum (doing ceremonies without understanding purpose)
  • Coach others on the reasoning behind Scrum practices

Connection to Scrum Values

Scrum theory and the Scrum values work together:

  • Openness enables transparency
  • Courage enables honest inspection
  • Commitment enables meaningful adaptation
  • Respect enables self-organization
  • Focus enables time-boxing discipline
