Improve Collaboratively, Evolve Experimentally

Improve Collaboratively, Evolve Experimentally in Kanban

Why It's Important

The principles of 'Improve Collaboratively, Evolve Experimentally' form a cornerstone of Kanban methodology. These principles are vital because they:

• Ensure continuous improvement through teamwork
• Reduce resistance to change by making incremental adjustments
• Create a culture of experimentation where failure is accepted as learning
• Empower teams to own their process improvements
• Use scientific methods to validate changes rather than opinions

What It Is

'Improve Collaboratively' means leveraging collective intelligence to enhance processes. It recognizes that:

• Teams closest to the work understand it best
• Diverse perspectives lead to better solutions
• Shared ownership increases adoption of changes
• Collaboration builds trust and psychological safety

'Evolve Experimentally' means using scientific approaches to change:

• Making small, controlled changes
• Testing hypotheses with measurable outcomes
• Learning from both successes and failures
• Building on what works and discarding what doesn't
• Using metrics to validate improvements

How It Works

Improve Collaboratively:

1. Regular improvement meetings - Teams hold cadenced sessions (like Kanban meetings or retrospectives) focused on identifying improvements

2. Cross-functional participation - Including perspectives from different roles and specialties

3. Shared models - Using visualization techniques like the Kanban board to create common understanding

4. Respectful disagreement - Encouraging healthy debate while focusing on facts

5. Consensus-seeking - Working toward solutions everyone can support

Evolve Experimentally:

1. Hypothesis formation - "We believe that [change] will result in [outcome]"
2. Small, safe-to-fail experiments - Making changes that can be reversed if needed

3. Collecting data - Measuring the impact of changes

4. Evaluating results - Honestly assessing whether the experiment worked

5. Amplifying or dampening - Expanding successful changes or rolling back unsuccessful ones

Practical Application Examples

• Adding a new column to the Kanban board to visualize a previously hidden workflow stage
• Testing a new WIP limit to improve flow
• Implementing a temporary expedite lane for urgent items
• Revising team agreements based on lessons learned
• Changing the frequency or format of team meetings

Exam Tips: Answering Questions on Improve Collaboratively, Evolve Experimentally

Key Concepts to Understand:

• These principles encourage evolutionary change rather than revolutionary transformation
• They focus on empirical evidence over abstract theories
• They value team intelligence over individual genius
• They create a learning organization that adapts to changing conditions

Common Question Types:

1. Scenario-based questions: When presented with a scenario, look for answers that:
• Involve the entire team in decision-making
• Suggest small, incremental changes
• Include measurement of results
• Allow for adaptation based on feedback

2. Comparison questions: When comparing approaches, remember that these principles favor:
• Evolutionary over revolutionary change
• Bottom-up over top-down improvement
• Empirical over theoretical
• Multiple small experiments over single big bets

3. Implementation questions: When asked about implementing improvements:
• Start with visualization to create shared understanding
• Use data to identify improvement opportunities
• Involve the whole team in suggesting solutions
• Design experiments with clear hypotheses and measurements
• Review results collectively

Key Phrases to Look For:

• "Collaborative improvement"• "Evolutionary change"• "Safe-to-fail experiments"• "Empirical approach"• "Team-based learning"• "Incremental enhancement"• "Hypothesis testing"• "Metrics-driven decisions"
Common Pitfalls to Avoid:

• Confusing evolution with revolution - Kanban prefers small steps over big bangs
• Thinking individual expertise trumps collective intelligence
• Assuming changes must be permanent - experiments can be temporary
• Selecting improvements based solely on popularity rather than evidence
• Implementing changes too broadly too quickly

Remember that in Kanban, improvement is not a one-time event but an ongoing process of collaborative experimentation. The best exam answers will reflect this continuous, team-based, and evidence-driven approach to enhancement.
