Value stream mapping for people who've outgrown whiteboard photos and want their process to feel wrong before they have to argue it's wrong. Work flows as a river; bottlenecks attract ravens; demand sliders break the system live.

Value Stream World hero showing Flow / Scale / Pressure metaphors and the Flow State ideal example
Hero. Flow / Scale / Pressure — three ways to read a stream.
The DevOps Transformation stream config — sliders for demand (items/day) and a chart of how soon the 100x / 1,000x / 10,000x / 50,000x item finishes, with bottleneck info
Configure. Crank demand and see when the system breaks.
Night-time city scene of the DevOps Transformation stream with steps Story Refinement → Development → Pull Request Review and waiting times labelled on each gap
Open the gates. Work flowing through the stream after dark.
Day 32 — work piling up at Change Approval (work piling up flag, 12 hours wait), red bills floating, deploys lagging, days lost
Day 32. Change Approval is bleeding the system.
Day 45 — Main Branch flagged with high failure rate, building still running, ravens circling, $90.5K of red value lost
Day 45. Main branch on fire, ravens circling.

Buildings are sized by cycle time, gaps by wait. Crank up demand and watch WIP pile up while ravens circle the bottlenecks.

Three lenses:

  • Flow — work as a river through the system
  • Scale — buildings = cycle time, gaps = wait
  • Pressure — push demand, see where it breaks

Ships with example streams (Flow State, Startup Sprint, Enterprise Release Train) plus an AI "generate one for me" mode.
