The same Monday morning, three ways
96 paid fills across 15 preparations. 2 catalog exceptions. A draft never sent, an order never acknowledged, an order 4 vials short. Every column below is showing exactly that.
A · Queue-first
What needs a person, ranked. Open full size
B · Order-first
The ledger of purchase documents. Open full size
C · Exception-first
Only what has stalled. Open full size
What differs, on five axes
| Axis | A · queue-first | B · order-first | C · exception-first |
|---|---|---|---|
| Primary object | A work item — an action owed | A supplier order — a document | A stall — something that stopped |
| Home screen | Buckets of pending action | The orders index | Only what is broken or ageing |
| Unit of action | Batch — many items, one act | Document — advance one order | Single item — resolve one thing |
| Screens | 7–9, two modes | 4 | 4 |
| Characteristic failure | Work outside a bucket is invisible | Demand that never reached an order has no home | On a good day the home screen is empty |
How the ten scenarios landed
3 · 2 · 3, with 2 unwinnable| Scenario | A | B | C |
|---|---|---|---|
| S1 · Cold start Monday | wins | 2 clicks | hides the real work |
| S2 · 100 fills, 15 preparations | wins | close | must leave the concept |
| S3 · Where is Rx #482? | fails | fails | fails |
| S4 · Pins conflict | 1 click | homeless | wins |
| S5 · No active pin | 1 click | homeless | wins |
| S6 · 4-day-old draft | close | needs a sort | wins |
| S7 · Sent, never acknowledged | no data | no data | no data |
| S8 · 8 of 12 arrived | throughput only | wins | nowhere to record it |
| S9 · Undo before sending | loses the trail | wins | not a stall |
| S10 · On a phone at the bench | wins | worst mobile case | answers a narrower question |
The scenarios do not partition by concept. They partition by phase of work. A wins origination, C wins blockage, B wins the document. S3 and S7 are unwinnable by any architecture — they are missing capabilities (cross-object search, and an acknowledgement state) rather than IA choices.
