 #### Maturation Phases
 1. several sprints to learn scrum, learn small increment, 
+2. over time focus shifts to organisations interaction with teams
+3. iteratively teams are transformed. They deliver quickly and change direction quickly, meaning the organization has strategic opportunities to plan and execute differently and better
+4. meaning everything gets better and better over time.

+#### Summary of Key principles
+- **Inspect and Adapt**: Agile is empirical with focus on learning from experience. Meaning the framework should create opportunities to reflect periodically and make adjustments based on experience.
+- **Start with Scrum**: might not be the final journey, but is the best structured and best supported place to start.
+- **Build Cross-Functional Teams**: The teams should be self managed, meaning they need to include a full skillset to make well informed decisions that are binding to the organisation.
+- **Integrate Testers into the Development Team**: Close feedback loop between development and test by having the people work together.
+- **Motivate Teams Through Autonomy, Mastery, and Purpose**: Motivation factors are inherently supported: Teams work with Autonomy and to become better over time (Mastery). healthy Agile team and motivated Agile team are strongly intertwined.
+- **Develop a Growth Mindset**: Agile teams have a big steady focus on getting better.
+- **Develop Business Focus**: Developers should understand the business to fill the gaps in requirements.
+- **Tighten Feedback Loops**: Don't take any longer to learn lessons than you need to. This supports more rapid progress from Inspect and Adapt and faster imporvements in Effectiveness.
+- **Fix the System, Not the Individual**: If a developer is not performing look for the system problem that is frustrating the person. Usually it's the system, not the people.
+- **Increase Team Capacity by Building Individual Capacity**: Team attributes are the combination of individual members attributes and interactions. By strengthening the people, you strengthen the team.
+- **Keep Projects Small**: They are easier and more often successful. Not all work can be structured like this, but if you can you should do it.
+- **Keep Sprints Short**: they support a frequent inspect and adapt feedback loop and expose problems quickly before they grow into large problems
+- **Deliver in Vertical Slices**: Feedback is important  and teams get better feedback on their product in vertical slices and thus improve more. This means the business improves more as well.
+- **Manage Technical Debt**: Focus on Quality. Managing technical debt supports higher team morale, faster progress and higher quality products.
+- **Support Large Agile Projects Through Architecture**: Good architecture even allows large projects to use agile. Good architecture can make a large project feel smaller
+- **Minimize the Defect Detection Gap**: The cost of fixing a defect grows with the age of the defect. --> Detecting early and fixing it is cheaper and increases quality.
+- **Create and Use a Definition of Done**: a good definition of done helps catch incomplete or faulty work early, minimizing the gap between defect insertion and detection.
+- **Maintain a Releasable Level of Quality**: High quality helps catching additional defects that slip through
+- **Use Automated Test, Created by the Development Team**: Helps minimizing the defect detection gap. Everyone on the team feels responsible and reinforces that quality is the responsibility of everyone.
+- **Refine the Product Backlog**: this ensures the team tackles high priority tasks first and doesn't invent new requirements
+- **Create and Use a Definition of Ready**: make sure requirements are truly ready before the team begins implementing them.
+- **Automate Repetitive Activities**: You have more benefits when automating repetitive tasks.
+- **manage to Outcomes, Not De**
