History of Lean
@PavelChunyayev
Lean manufacturing
@PavelChunyayev
Lean manufacturing - Principles• Elimination of waste• Continuous improvement• Respect for people• Pull instead of push• Just in time production• Quality built in
@PavelChunyayev
Lean manufacturing – Forms of Waste• Mura – Waste because of variation• Muri – Waste because of unreasonable work• Muda – Waste that doesn’t add value
@PavelChunyayev
Lean manufacturing – Types of Waste• Transportation• Waiting• Overproduction• Defects• Inventory• Movement• Extra processing
@PavelChunyayev
Lean manufacturing – Metrics• Process time• Delay time• Lead time• % complete and accurate
@PavelChunyayev
Lean thinking• Value• Value streams• Flow• Pull• Perfection
• Build quality in• Understanding ‘takt’ time• Reducing batch sizes• Pull system• Continuous improvement• Focus on long-term goal
@PavelChunyayev
Lean ITGoals:• Increase productivity • Increase customer benefits• Continuous improvement process
@PavelChunyayev
Lean IT - Trends• Reducing costs (eliminating waste), six sigma• Transformation to utility• Outsourcing (e.g. Cloud)
@PavelChunyayev
Conflict with DevOps?• Innovation and disruption vs Operational excellence • Experimentations vs Predictability• Unstructured and uncertain vs Standards and variation avoidance
@PavelChunyayev
Lean and DevOps• It’s not only about costs• Continuous learning• Build quality in• Visualize• Think backwards from customer value• Not from current capabilities
• Embrace uncertainty
@PavelChunyayev
Lean software development
@PavelChunyayev
Lean software development - Principles• Eliminate waste• Amplify learning• Decide as late as possible• Deliver as fast as possible• Empower the team• Build quality in• Optimize for the whole
@PavelChunyayev
Waste • Partially done work (Starting more than finishing)• Extra processes (Bureaucracy)• Extra features (Unnecessary code)• Task switching (Changing requirements and priorities)• Waiting (Delays in the development process)• Motion• Defects (Quality issues, rework)
@PavelChunyayev
Amplify learning• Pair programming• Code reviews• Documentation• Wiki• Commented code• Knowledge sharing sessions• Training
@PavelChunyayev
Decide as late as possible• For decisions that are irreversible or impractical to reverse• Keep the options for as long as possible• You will know a lot more by the time the decision needs to be made
• Too early and you are limited by the choice you could have made without enough information
@PavelChunyayev
Deliver as fast as possible• Continuous Delivery• DevOps• Agile methodologies
• Shared responsibility
@PavelChunyayev
Empower the people• Give responsibility to make decisions about their work
@PavelChunyayev
Build quality in• Andon – stop the line• Pair programming• Test driven development• Constant feedback• Minimize handovers (time between stages)• Continuous integration• Automation
@PavelChunyayev
Optimize for the whole• Optimize for the whole, not specific departments or teams• E2e process with focus on customer needs
• Prefer product orientation vs project orientation• Focus on quality and innovation, not on quick execution
@PavelChunyayev
Problems of Lean• Focus on tools, not on the philosophy and culture• Decide on the solution without understanding true problem• Cargo cult
