design-heuristics EventStorming

Short description

From a process or design level EventStorming, design your bounded contexts around the purple sticky called a policy.


  • When a domain experts mentions: When this event happens we will start the reservation process. We can add a policy that can be names: Reservation process policy
  • Sometimes a policy is a long running process for instance a timer to cancel a reservation when the ustomer has not payed. You can design these within your bounded context instead of spanning between.


During process and design level EventStorming we want to design our bounded context. Since we usually take a customer journey or a product it can span multiple bounded contexts.
