However, owners don't usually undertake the effort and expense of a capital project in order to simply say that the project was great. Owners want buildings that stay great and meet the needs of the people and programs for which the buildings were designed and constructed.
That means that one definition of a great building is a facility whose systems continue to perform as intended for as long as the owner needs them to perform. Two of the cornerstones of commissioning - documentation and training - are focused on this goal. Systems will not have a prayer of functioning as intended if the people responsible for maintaining and operating them are not provided with the tools and knowledge necessary to do so.
