Principles
sub-optimize the overall system.
Focus on the Entire Value Stream
From concept to cash.
From customer request to deployed software.
Deliver a Complete Product
Customers don't want software; they want their problems solved.
Complete solutions are built by complete teams.
Think Long Term
Beware of governance and incentive systems that drive short term thinking and optimize local performance.
The three biggest wastes in software development are:
Building the Wrong Thing
"There is nothing so useless as doing efficiently that which should not be done at all." –Peter Drucker
Failure to Learn
Many of our policies – for example: governance by variance from plan, frequent handovers, and separating decision-making from work – interfere with the learning that is the essence of development.
Thrashing
Practices that interfere with the smooth flow of value – task switching, long lists of requests, big piles of partly done work – deliver half the value for twice the effort.
Final Verification Should Not Find Defects!
Every software development process ever invented had as its primary purpose to find and fix defects as early in the development process as possible.
Mistake-Proof your Process with Test-First Development
Tests – including, unit tests, end-to-end tests, and integration tests – must be available to establish confidence in the correctness of the system at any time during development, at every level of the system.
Break Dependencies
System architecture should support the addition of any feature at any time.
Predictable Performance is Driven by Feedback
A predictable organization does not guess about the future and call it a plan; it develops the capacity to rapidly respond to the future as it unfolds.
Maintain Options
Think of code as an experiment – make it change-tolerant.
Last Responsible Moment
Learn as much as possible before making irreversible decisions. Don't make decisions that will be expensive to change before their time – and don't make them after their time!
Rapid Delivery, High Quality, and Low Cost are Fully Compatible
Companies that compete on the basis of speed have a big cost advantage, deliver superior quality, and are more attuned to their customers' needs.
Queuing Theory Applies to Development, not Just Servers
Focusing on utilization creates a traffic jams that actually reduces utilization. Drive down cycle time with small batches and fewer things-in-process. Aggressively limit the size of lists and queues
Managing Workflow is a lot easier than Managing Schedules
The best way to establish reliable, predictable deliveries is to establish reliable, repeatable workflows with iterations or a kanban system.
People who are paid fairly and adequately are motivated by autonomy, mastery, and purpose.
Autonomy
The most effective work groups are semi-autonomous teams with an internal leader with end-to-end responsibility for complete, meaningful tasks.
Mastery
Respect for people means providing the challenge, feedback, and environment that enables everyone to become excellent.
Purpose
Tie work to value. Only by believing in the purpose of their work will people become engaged in achieving that purpose.
Failure is a Learning Opportunity
The most reliable performance comes when even small failures are deeply investigated and corrected; when noise is not tolerated.
Standards Exist to be Challenged and Improved
Embody the current best known practice in standards that everyone follows, while actively encouraging everyone to challenge and change the standards.
Use the Scientific Method
Teach teams to: establish hypotheses, conduct many rapid experiments, create concise documentation, and implement the best alternative.

Leading Lean Software Development:
Results are not the Point
Building on their breakthrough bestsellers Lean Software Development: Concept to Cash and Implementing Lean Software Development: An Agile Toolkit, Mary and Tom Poppendieck's latest book shows software leaders and team members exactly how to drive high-value change throughout a software organization–and make it stick.
Implementing Lean Software Development:
From Concept to Cash
This book draws on the Poppendiecks' unparalleled experience helping development organizations optimize the entire software value stream. You'll discover the right questions to ask, the key issues to focus on, and techniques proven to work. The authors present case studies from leading-edge software organizations, and offer practical exercises for jumpstarting your own Lean initiatives.
Lean Software Development
An Agile Toolkit
Lean Software Development shows software professionals how to achieve breakthrough quality, savings, speed, and business value by adapting the seven "lean" principles that have already revolutionized manufacturing and R&D. Drawing on 25+ years' experience leading enterprise projects, the authors show how to use these principles to create agile processes that work - because they're optimized for your environment.
