Value stream mapping that calculates.
Rother and Shook symbols, lead time and takt time live from your process data, future-state scenarios with payback. Not a drawing tool with VSM shapes, but a calculation tool that happens to draw a standards-compliant map.
The demo runs without signing up: a complete value stream with five processes, inventory and calculated metrics. Change one cycle time and watch the lead time respond.
Part of a current state as the editor draws it: from supplier to customer, process boxes with C/T, C/O and OEE, inventories in pieces, the bottleneck marked red, above it the information flow in blue, below the timeline with lead time.

Company overview
Three modules for the same line
Your lines appear in three places: in the value stream as a process box, in the capacity analysis as a planning unit over twelve months and in daily planning for the next production day. All views run on the same master data and can be used independently.
Value stream mapping
Current and future state, Rother & Shook symbology, every metric with its own visible arithmetic. Plus an industry benchmark (your own cycle time/OEE against reference values by industry and company size) and CSV bulk import for existing process lists.
How a value stream map is madeCapacity management
A 12-month view per line, an automatic traffic light from the load rate (demand ÷ monthly capacity), and a built-in recommendation — from cutting changeover times to outsourcing.
Daily planningPilot
Setup plan and shift plan for tomorrow, setup conflicts in the Gantt, forecast of machine time and direct labour productivity — then plan against actuals, day close and measures. For production where people look after several machines.

Taktane doesn't replace a workshop facilitator — it provides the numbers that come out of the room. Process data gets into the system today by manual entry or CSV import; there's no live ERP connection yet.

Capacity and productivity
Where will it get tight in the next twelve months, and how productive was last month against last year?

Daily planning
Plan the next production day from setup plan and shift plan and see whether staff and machine time fit.

Day close
The morning after, answer four questions and close the day with a short code — in a few minutes.
How the daily routine works
Every number shows its own arithmetic
Under each metric sits the formula with the values actually used. A surprising number therefore explains itself from its own inputs, instead of looking like a defect.
- Lead time
- WIP ÷ output
- Little’s Law across every inventory point in the chain.
- Takt time
- Available min/day ÷ customer demand
- Derived from annual demand and shift pattern, not estimated.
- Process cycle efficiency
- Value-added time ÷ lead time
- The number that starts the discussion in the steering committee.
- Actual output
- Available min/day ÷ bottleneck
- Effective cycle time including OEE, not the nominal one.
The tool pushes back
A value stream can be methodologically wrong and still look fine. The method check runs on every change and ranks by severity: first what invalidates a metric, then what only affects the drawing.
Metric affected
Capacity shortfall
If the line cannot meet customer demand, inventory grows without bound. Little’s Law no longer holds, and the tool says exactly that instead of claiming a lead time.
Methodologically unsound
Push upstream of the pacemaker
Everything upstream of the pacemaker needs a pull system. Where a connection still runs as push, it is named and counted.
Methodologically unsound
No pacemaker set
Without a pacemaker, the ERP schedules every process individually. The map shows it that way, and the note explains why that is rarely intended.
From current state to business case
Each future-state scenario takes shape along the eight questions from Rother and Shook and is its own copy of the value stream. The comparison places them side by side and translates the lean metrics into the language budgets are decided in.
| Metric | Current state | Scenario A |
|---|---|---|
| Lead time | 18.4 days | 9.1 days |
| Process cycle efficiency | 0.41% | 0.83% |
| Working capital tied up | €1.4M | €0.7M |
| Investment | – | €85,000 |
| Payback | – | 14 months |
| Risk | – | Medium |

Built for the room where the value stream is created
A VSM is not filled in at a desk, it is worked out in front of the group. Afterwards it has to fit on a sheet that someone else reads.
- Presentation mode
- Hides import and renaming. Process boxes stay editable, because a value stream is created in the room with the team and is not finished beforehand.
- Full screen
- One movement space instead of three. For the projector in the meeting room and the laptop on the shop floor.
- PDF export
- Map and metrics on A4 landscape. The sheet that goes into the committee.
- 26 terms explained in context
- Pacemaker, supermarket, FIFO, heijunka, EPEI. Explained where they appear, so green belts and operators can follow.
The data sheet for the shop floor
A printable data-collection sheet with measurement instructions, ungated and without sign-up — for the moment the numbers come from the machine, not the desk.
One line from the instructions:
Changeover: from the last good part of the old variant to the first good part of the new one. Enter 0 where there is no changeover.
Where your data lives
A value stream describes your production: takt times, inventory, bottlenecks. Anyone working with it wants to know up front where that is stored.

Start without prior knowledge
What is a value stream map, when does capacity planning pay off, what does daily planning measure? The learn section explains each module with an example and the procedure, plus a glossary of all terms.
Look first, decide after
The demo needs no account and no company address. Anyone who then wants to build their own value streams will find the same functions in the tool.
