Please Note: The contributing authors to these FAQs have tried to be very careful not to formulate the answers as though they are making definite statements or giving precise recommendations. The FAQs attempt to be a guide to existing material and principles: they seldom give categorical "answers". The contributors know that they cannot make precise statements without knowing the background of each user. Excessive specificity in answers would likely lead to misunderstanding, misinterpretation and disappointment. There are no simple answers to the important questions included in the FAQs. The authors provide frameworks for thinking about issues and include resources for pursuing more detailed responses. They believe that no general recipe for good regulation and good management exists. Despite such disclaimers, the infrastructure professionals responsible for assembling the FAQs feel that asking the right questions is an important step in the journey towards improving performance in the energy, telecommunications, water, and transportation sectors.
