This means a reading prerequisite—since we will talk about methods of analyzing information systems, you should have previous analytical contact with them at least. Sure, everyone uses them nowadays, but you will need a bit more than just experience using them, in particular some knowledge about the different parts they are made of. Nothing fancy here, but you need to understand the difference between software and hardware and that information systems are generally there to automate business processes, which are sets of human and computer-based tasks organized toward reaching a goal. You will also need to be able to recognize the different parts of such a system.
