Variability & Uncertainty is a fact
of life in SW• Embrace helpful variability to create innovative solutions
• Employ iterative and incremental development
• Leverage variability through inspection [review], adaptation, and transparency
• Reduce forms of uncertainty [features]

Prediction & Adaptation• Keep options open
• Accept that you can't get it right up front
• Favor an adaptive, exploratory approach
• Embrace change in an economically sensible way
• Balance predictive up-front work with adaptive just-in-time work

Validated Learning
Validate important assumptions fast
• Fail fast by having short dev cycles (sprints)
Leverage multiple concurrent learning
loops
• stand-ups, reviews
Organize workflow for fast feedback
• reviews, retrospectives
Assume
Build
Feedback
Inspect
Adapt

Work in ProgressUse economically sensible batch sizes
• Short sprints
Recognize inventory [work] and manage it for good flow
• Focus on idle work, not idle workers
• Reduce cost of delay

Progress
• Adapt to real-time information and replan
• Measure progress by validating working assets
• Focus on value-centric delivery

Performance
• Go fast but never hurry
• Build in quality
• Employ minimally sufficient ceremony
