Request and wait handshake
Use when
- You send an asynchronous request and wait for a reply or a timeout.
- You need an SLA window and a clean outcome on either path.
Pattern in simple words
- Start.
- Send task: Send payment request.
- Event‑based gateway: wait for one of the following.
- Message event: Payment received. End Paid.
- Timer event: Fourteen days elapsed. Service task Close unpaid. End Closed unpaid.
Result
The process routes to one of two outcomes depending on which event occurs first: the paid path if a payment message is received, or the closed-unpaid path if the fourteen-day timer elapses.
Note:
This pattern cleanly models asynchronous communication with an SLA.
Other scenarios
- Finance: Invoice payment versus due‑date closure.
- Insurance: Claim evidence versus expiry.
- Retail: Supplier confirmation versus alternate sourcing.
- Public sector: Response received versus auto‑close.
- Manufacturing: Order acknowledgment versus cancel.
Wait for a specific message with a deadline
Use when
- A precise message is expected before continuing.
- A deadline must trigger escalation if the message does not arrive.
Pattern in simple words
- Start.
- Receive task: Await specialist report, with an interrupting boundary timer set to five days.
- On timer: User task Escalate. End Escalated.
- Normal path: Receive report. User task Review report. End Reviewed.
Result
The process completes on one of two paths: the reviewed path if the specialist report arrives within five days, or the escalated path if the boundary timer fires before the message is received.
Note:
The timer defines the SLA and triggers escalation.
Other scenarios
- Finance: Await audit response versus escalation.
- Healthcare: Await patient records versus escalation.
- Retail: Await vendor confirmation versus procurement escalation.
- Manufacturing: Await QA test results versus manager escalation.
- Public sector: Await citizen reply versus auto‑close.
