Value stream map
Native value-stream maps (VSM) for lean process analysis. Declare process boxes with their data — `process Weld { ct: 45s; co: 30m; uptime: 85%; operators: 2 }` — and the inventory or wait time between them, and the engine draws the timeline ladder and COMPUTES what the map exists to show: total lead time, total value-added time, flow efficiency, and the takt comparison. The one process diagram whose numbers are an analysis rather than a caption.

Most users come to Value stream map from eVSM, iGrafx, Lucidchart value stream maps or Visio lean templates. flowss runs this engine in the browser — no install, shareable via URL, exportable to PNG / SVG / PDF / source.
Syntax at a glance
customer "Despatch" demand: 320/day
process Weld { ct: 45s; co: 30m; uptime: 85%; operators: 2 }
wait 22m
process Paint { ct: 90s; uptime: 92% }Paste this in the Studio code pane to see Value stream map render live. The full grammar is at the upstream-docs link above.
Sample templates
All 13 →Current-state map of an emergency department running 320 patients a day, computing the 6.7-hour lead time against 93 minutes of clinical work and naming imaging as the capacity constraint.
Body-in-white front door line from steel coil to trim, showing the classic ~1% flow efficiency of a batch-and-queue plant and marking the paint shop as the monument that breaks takt.
Commit-to-production flow for a team shipping twenty changes a day: 2 hours of work inside a 1.3-day lead time, with a 50% rolled throughput yield exposing how much rework code review and the integration suite create.
Mortgage origination from application to funding: 4.7 hours of processing spread across a ten-day lead time, with a 35% rolled throughput yield quantifying the rework loop caused by incomplete documents.
Dinner service from ticket to table at a declared 45-second takt, the rare stream with 60% flow efficiency, showing three of the five stations unable to keep pace with the pass.
Pick-to-despatch flow for 4,200 next-day parcels a day at a 13.7-second takt, showing a well-balanced stream where no station breaks takt yet only 2.5% of the lead time adds value.
