2- The theory of empiricism
The Scrum Guide states that: “Scrum is founded on the theory of empirical process control, or empiricism. Empiricism asserts that knowledge comes from experience and decision-making is based on known facts. Scrum uses an iterative and progressive approach to optimize predictability and risk control. "

  • Transparency
  • Inspection
  • Adaptation

They allow:
• Make empiricism emerge on a lasting basis.
• Constantly improve quality.
• Offer a real and objective view of what is happening.
• Give each participant a global vision of what they are helping to achieve.
• Involve the teams in the choices structuring their activity.
• Give meaning to the work done, thus increasing intrinsic motivation.
• All this without having to "police" each individual.


4- The 5 values:
"When the values ​​of commitment, courage, focus, openness and respect are embodied and lived by the Scrum team, the Scrum pillars of transparency, inspection and adaptation come to life and build trust between everyone. 
Members of the Scrum Team learn and explore these values ​​as they work with Scrum events, roles, and artifacts.
"
