Simplify processes whenever you can. To do so ask yourself if a complex process really requires so many actions. If not, make it easier, considering creating value for the people involved.
Focus on simple things that create value, rather than following complex processes just because they have been in use for a long time. Ask why there are complex steps and unless there is a solid and current reason, stop doing them. Use the minimum number of steps you need and do nothing that is not creating value for one of your stakeholders.
One implication of this principle is that their processes need to cover the basics and should not be designed to cover all possible situations. Empower people to recognize when they need to do something different, and then trust them to do so. If everyone in an organization has a good understanding of ITIL’s guiding principles, then they must make the right decisions in most situations.
