And the third guiding principle is progress iteratively with feedback. And very much the idea of progress iteratively with feedback is to try and often take often what's quite large chunks of really service change, and breaking that down into more manageable pieces of work. And hopefully by doing that, not does it just ensure that we can produce something meaningful to the business more quickly, and therefore really derive better value through providing services back to the organization in a more efficient way, but it also allows us better to control each individual iteration of change that we do, and always with the eye through that around the focus on value that we need, linking back to one of the other principles. But we always say progress iteratively with feedback, and the feedback is critical because feedback shouldn't just occur once we've delivered a small, manageable piece of work back to the organization. Feedback should occur really all the way through, and by doing that, we're gonna get that concept of real focus round the consumer needs back to the co-creation of value principle that is so critical to ITIL 4, and therefore every iteration we're producing something of meaningfulness back to the organization. And we're doing that in so much more of a speedier and efficient way.
