In this unit, we begin looking at formal modeling diagram syntax for information systems. However, you may find that many organizations do not use these formal modeling techniques, and instead use rough drawing techniques (what I call “boxes and arrows”). Why are these formal techniques important, and if you are working with an IT organization that has not adopted a formal standard for process modeling, what might be your advice to entice them to do so?
As an IT auditor, what is the benefit to you if organizations use standard techniques to model their processes and systems, and what challenges might you have in organizations where no such standards exist?
