Optimizing predictable vs complex workflow steps

AspectPredictable (ordered) workComplex (uncertain) work
Nature of the workCause and effect well understood and repeatableCause and effect clear only in hindsight; novel
How to optimize itStandardize into a clear procedure and automate itExperiment, collaborate, and use rapid feedback
Worked exampleRoutine password resetDeveloping a new digital product
If you mismatch the methodAutomating complex work reduces valueLeaving predictable work manual wastes speed and consistency
What good looks likeSpeed and consistencyLearning and adaptation, with work still flowing

Cheat sheet

  • Workflows should be optimized according to the complexity of the work, not with one uniform approach.
  • Predictable (ordered) workflow steps are optimized through standardization and automation.
  • Complex workflow steps are optimized through experimentation and feedback, not rigid procedures.
  • Value streams are applied by combining the eight lifecycle activities into a scenario-specific path.
  • The same activity can appear in several value streams and more than once within one stream.
  • Each value stream path is optimized for the complexity of its own scenario.
  • Different types of demand require different value streams.
  • Applied value streams include operational streams (e.g. incident resolution) and development streams (e.g. new features).
  • Applying value streams aims to keep work flowing smoothly through each scenario's path.
