Heijunka
Level the mix of a line, a pick area or a packing station the way Rother and Shook and Art Smalley describe it. Enter the time the line has and what each product needs, and see the takt, the pitch, the load and the EPEI, the day's sequence in a heijunka box with clock times, and what levelling costs in changeovers and saves in finished stock and in uneven hours. The box prints on A4 for the line.
2 · Products and families
Demand for the same period as the working days. Cycle time per unit at this line, in seconds; the pack-out is the units in one container (a tote, a case, a pallet); the changeover is the time to change over to this product. To shorten it, use SMED Changeover.

Your work
All your work in one file
Every tool keeps your work only in this browser. Save it as one file to keep a copy, to carry on from another phone or computer, or to hand it to a colleague. Nothing is uploaded.
Then clear old entries in these tools to make room: the file keeps them, and opens on any device.
Works offline too: once a tool has been opened on this device, it and the other tools of its role open without a connection.
Team sync Off
Share the tools you choose with your team: every device keeps working without a connection and syncs when it can. The work is encrypted on this device with a key made from the team code, so the server cannot read it.
Your team code
On another device, open this box and scan the code or type the six words under “Join a team”. Give it only to your team: whoever has it can read and change the shared work; for someone who should only look, make a read-only code instead. Write it down; it is not shown again.
Read-only: this device takes the team's work and sends nothing, so it can neither change nor delete the team's copy. Changes made here to the shared tools are not sent, and the next sync replaces them with the team's copy.
For someone who should see the team's work but not change it, such as a manager or a screen on the wall. It cannot change or delete anything.
When someone leaves the team: the work moves to a new code and the old copy is deleted. Every other device then joins again with the new code, and the old read-only codes stop working.
Read-only code
On the other device, open this box and scan the code or paste it under “Join a team”. Whoever has it can read the shared work, so give it only to people who may see it. It stops working when the team changes its code.

- Six Sigma · 5 minSigma & Control Cha
r tTurn defects into a sigma level, combine on time, undamaged and complete into perfect delivery, and see whether a bad day is a signal or noise.→ - Worksheet · 10 min5 WhysMove from a symptom to a root cause you can change, then agree one countermeasure, one owner and one check. Print it or save it as PDF.→
- Root causes · 15 minFishbonePut the effect at the head and collect causes with the team on the 6M, 4P or hotel bones, each with its why. Votes and likely causes rank them, the likely ones become actions to verify, and the top one goes to 5 Whys or the causes to Pareto.→
- Risk · 30 minFMEAWrite down how each process step can fail, rate severity, occurrence and detection, and get the RPN and the AIAG-VDA action priority. A heat map, the top ten risks and the actions with owners until the re-rating shows the risk is gone.→
- Six Sigma · 10 minProcess LabPaste measurements and get the right control chart (I-MR, Xbar-R/S, np, c, u) with Nelson rules and before/after phases, Cpk, chi-square, regression and a Gage R&R or attribute agreement study. Every number in plain words.→
- Lean · 20 minTime StudyTime each element over five cycles with a stopwatch, space bar as the lap key. Get the standard time per station, takt from demand, a Yamazumi against it and the first element to move.→

r tfolioEvery DMAIC project on one page: phase, status, the next tollgate and its checklist, days in the phase, sigma before and after, and savings planned against realised. Each project keeps its charter, SIPOC, CTQ tree, RACI, Kano, RTY, COPQ and control plan.→ - Inventory · 15 minABC/X

Days open and to containment against targets, every action to the tracker, print and Word.→ - Strategy · MonthlyHoshin KanriThe site's strategy on one X-matrix: breakthrough and annual objectives, improvement priorities, metrics and their owners, with the gaps listed. Catchball notes per priority, a bowling chart month by month, and a countermeasure when a metric misses twice in a row.→
- Overview · WeeklySite CompareThe sites you look after side by side, each read from its read-only team code without joining: damage and incomplete rates, routes on time, OEE, 5S, safety, actions, maintenance and the hotel rates, best and worst named, ranked by a rule you can see.→

Report-out in A4 and Word.→
- Six Sigma · 20 minCost of Quali
t yList what prevention, appraisal, internal and external failure cost, as hours, counts or amounts for any period, and get the cost of quality a month and a year, the cost of poor quality as a share of revenue, the largest items and what a cut in failure would save.→ - Inventory · 15 minKanban SizingWork out how many kanban cards each supermarket or two-bin loop needs, by Toyota's formula or a statistical safety stock, see the cards to add or take out and the stock value at maximum, and print the cards eight to an A4 sheet.→
