Simulation: illustrative exampleOrder via WhatsApp → invoice · v1.0 · owner: Patrícia · Horizonte, fictional study company
Trigger: customer sends the order via WhatsApp. Completion: invoice issued and sent to the customer in the conversation.
Normal path (13 steps): reply → enter in the app → copy to the spreadsheet → check the price of every item → approve above R$ 5 thousand → print and take to the warehouse → check availability in the ERP → pick → notify Juliana → email to finance → retype in the ERP → check the customer record and issue the invoice → send the invoice.
Decisions: discount within policy? (rule) · above R$ 5 thousand? (rule) · discount between 5% and 10%: give it or not? (Patrícia's judgment) · customer with a complete record? (rule, today only at step 12) · product out of stock: deliver partially or wait? (judgment, with the customer).
Detours: D1 incomplete record: finance sends it back to customer service after picking ("about 15 a week," declared = hypothesis). D2 product out of stock: partial order, Juliana calls the customer (1 in 5 cases, observed).
Measures: 168 orders in the week of 10/13 (counted, dashboard) · 21 min of people time per order (median, 5 cases) · 30 h until the invoice (median, 5 cases) · longest wait: finance invoices the next morning, and the warehouse receives the papers in two batches (10 am and 3 pm).
