A business process concerns the order that things happen, and their consequences.

Here we show how adding and multiplying on a calculator affect the total.

|''with a calculator''|

|''given the total is''|10|

|''+''|5|

|''*''|10|

|''the total now is''|150|

But we don't get any useful feedback (by default) if the expected value is wrong:

|''the total now is''|140|

So we can use the special '''is''' instead, as follows:

|''the total now''|'''is'''|140|

as it shows what the actual result was. After all, it's just as easy to make mistakes in tests.
