Zooming Out
We just saw that there are many unique traces. The reason for this is that there are several stages in the process where various activities occur in parallel. This will create a unique sequence for each different ordering. When three activities can occur in any order, there are six different possible orderings. When we have another set of three parallel activities later in the process, the combined number of different orderings will increase to six times six, etc.
Let's work around this by collapsing those activities into a single activity instance. We have already collapse the sub processes Create Quotation, Production and Accounting. The sub process Delivery still needs to be collapsed.
