SIPOC maps a process at its widest level across five columns — Suppliers, Inputs, Process, Outputs, Customers — and fits on one page by design, with five to seven steps at most in the process column.
- Dobavitelji – kdo zagotavlja to, kar proces porablja (notranji ali zunanji)
- Vhodi – materiali, informacije ali zahteve, ki vstopajo vanj
- Proces – peščica glavnih korakov, ne podrobnosti
- Izhodi – kaj proces proizvaja
- Kupci – kdo prejme te izhode in jih presoja
Its purpose is agreement rather than analysis, which is why it belongs early, before anyone maps in detail. Getting a room to concur on where the process starts and stops usually reveals that they did not — better discovered before the measurement plan is written than after.
It is also the fastest way to establish who the customer actually is. Teams regularly find they have been optimising for a recipient whose judgement does not matter.
SIPOC z dvajsetimi procesnimi koraki ni več SIPOC, temveč je postal slab diagram poteka. Njegov namen je imeti celoten proces pod nadzorom na enem mestu; podrobno risanje procesov in Value Stream Mapping pa sta namenjena situacijam, ko je resnično potrebna večja podrobnost.
