The article emphasizes that the core is "standardizing and systematizing business execution processes," which means the processes themselves need to be clarified before implementing the system.
Several questions worth reviewing: Do each customer's quotation terms, payment conditions, and visible product range already have clear rules? In the current order process, which steps are done manually but could actually be handled by the system? Which steps must remain manual and require human judgment?
If these conditions aren't organized before going live, customers will encounter more confusion online than they did with email, because systems amplify problems. It's recommended to first complete and organize the process for one or two main customer segments, confirm that the conditions can be described in a structured way, and then start configuring the system. This way, when implementing, you'll have something concrete to map to and won't be changing requirements while going live.
