The diagram should explain itself. If you have a business that uses an HRIS product of any kind (PeopleSoft, Oracle, CostPoint, SAP, whatever) and have an Active Directory environment, *AND* you’re not automating the creation of user accounts (and group memberships) you’re an idiot (or just clueless). The diagram box labelled “Process” (see example) is so simple to implement it would make a third grader shake their head in disbelief that an adult couldn’t figure it out. It really is simple. There are scripts falling out of peoples asses across the Internet that make this easy to do. So, if you’re not doing this, get busy.
