Exercise $5\mathrm{.}6$ The order$-$to$-$cash process of your favorite online bookstore has ten major activities conducted by ten people with five different roles. How much time do you approximately need for creating a process model that is validated by the various stakeholders and approved by the process owner? Consider two scenarios: one in which you run interviews, the other in which you run workshops. You may also use other discovery methods in these two scenarios, in addition to either interviews or workshops. Can you estimate the difference in time effort between the two scenarios? Make appropriate assumptions.
