DateBatch or strainWalked by
Follow one batch from harvest to release. For each waste, write what you saw, where, and how often. Dry time, cure time and the test hold aren't waste. No solutions yet.
| Waste | What it looks like here | Where to look, what to ask | What I saw |
|---|---|---|---|
| DDefects | "Crispy" or case-hardened flower. Mold found in cure. Mislabeled totes, mixed grades. A failed yeast-and-mold test. | Dry and cure logs, lab results.Where would a dry check have caught it? | |
| OOverproduction | Everything trimmed to top grade when demand is for smalls. A whole room bucked before trim has room. | The vault, next to the packaging plan.What did we trim that is still waiting? | |
| WWaiting | Trimmers idle until the dry room releases. A lot sitting after its results came back. A line at the scale. | Staging, the scale, the vault.Outside dry and cure, where did it sit? | |
| NNon-utilized talent | The fastest trimmers washing totes. Graders' quality calls that never reach cultivation. | The crew, end of shift.What slowed you down today? | |
| TTransportation | Totes from dry room to trim to vault, then back for a regrade. Samples walked across the building. | Vault log, a floor plan.How many moves didn't change the flower? | |
| IInventory | Released bulk aging past its best window. Trim with no extraction plan. Stacked bins at every station. | The vault, trim storage, stations.How old is the oldest released lot? | |
| MMotion | Trimmers getting up to weigh every bag. Searching vault shelves for a lot. One shared scale. | Trim room, bucking area, vault.How many steps to finish one bin? | |
| EExtra processing | Hand touch-up on machine-trimmed bud. A lot weighed three times because scale and system disagree. | Weigh station, adjustment log.Why did we weigh or grade it again? |
Two numbers to write down: harvest-to-release days for this batch, and today's bud-to-shake.
