Lean Principles

ELIMINATE WASTE Speed! We only implement what‘s requested and releaseimmediately. Get feedback. And start over.

AMPLIFY LEARNING Learning is integral part of the project.

DECIDE AS LATE AS POSSIBLE Make decisions based on factsBuild in capacity for change

DELIVER AS FAST AS POSSIBLE Design, implement, feedback, improve

EMPOWER THE TEAM No fraction. Responsibility. Less control.

BUILD INTEGRITY IN We deliver business value, in small doses that make sense

SEE THE WHOLE Measure overall performance, not individual

BASELINE – ARCHITECTURAL PRINCIPLES

Business value over technical strategy

Strategic goals over project-specific benefits

Composability over silos

Shared services over specific-purpose implementations

Evolutionary refinement over pursuit of initial perfection

Design for obsoleteness over building for eternity

Good enough over best of breed

Declarative processes over implicit knowledge

Data over opinion
