Choose a product, insert the delivery address, choose type of dispatch, pay for the product, confirm order.
B.
Choose a destination, choose a connection, pay for the ticket, optionally reserve a seat, print out the ticket.
C.
Enter one or several e-mail addresses for recipients, optionally add further addresses for cc-recipients, write some text, optionally add attachments, send e-mail.
D.
Get on the bike, drive the bike, pedal, optionally changing gears, get off the bike.
Aparallel gatewaythat fans out to three branches (B, C, D), and
Aparallel gatewaythat joins all three beforeE.
This means:
After A, the process may carry outB,C, andDin parallel (or at least independently).
All active branches must complete before moving toE.
Scenario C fits this pattern:
A = enter primary recipients
B = optionally add cc-recipients
C = write the email text
D = optionally add attachments
E = send email
The optional activities (cc and attachments) can be done in any order while writing the text, but all work is complete before sending. The other scenarios are essentially linear or don’t naturally occur in parallel like this.
