Why are standards and best practices needed?
Standards and best practices are often misinterpreted as rules and let's face it, no one liked rules as a child, and no one likes them as adults. Instead of rules, think of them as guidance; guidance that can help you and your team (if you have one) work more efficiently with less frustration and confusion. A system set up and maintained with standards and best practices over the years is a much simpler system to upgrade once the newest version of ArcGIS Enterprise comes out. Also, with standards and best practices in place, it is easier to bring new employees on board and get them familiar with the environment.
