Hello everyone,

As I'm just starting out with BPMN 2 for school, I hope someone here can help me with the following situation; A pizza place ordering proces where a customer can either order through phone, website or at the store.

When ordering through the website or phone, you can choose if you wan't the order delivered or pick it up at the store. When ordering through website or at the store, you pay upfront. Ordering through phone means you pay afterward at the store or with the deliverer.  

Reading the Bruce Silver book I think there are several actors: customer (black-box perhaps?), storemanager/cashier, delivery boy and the chef. I thought of using channel-dependent start, but within this situation I find it hard to figure out how I should do that.

I'm finding it difficult to figure this out (first time using BPMN). I really appreciate some help and/or tips/tricks.

Have you checked out the available BPMN models for the pizza process?

Thanks Rune,

Yes I have seen some of those example models, but neither seem to take into account the different sources from which the order can come from (website/phone/at the restaurant itself). Also the moment of payment differs depending on where the customer orders the pizza.

What about creating variant processes to keep things clear ? Example Order online vs Order in store, with other words 2 BPMN processes with common activities which are shared between the models? Then you have 2 easy understandable processes ?

Thanks Etienne, 
That's might be a good way to go about it. For the purpose of the assignment I ended up defining the customer as a 'black box', then handling the order within an another pool with four lanes: order worker, chef, deliverer and cashier. Within the process I check if payment has been done and if the customer picks it up or has the pizza delivered. 
Thanks again.
