在审查和制定拟议的基础设施更换计划的整个过程中，可靠数据的重要性无论怎样强调都不为过。管道维护和更换的工程方面以及财务方面需要进行大量的协调工作，以证明需要更换计划，并帮助规划该计划。作者相信，随着我们进入未来，这些数据将更加重要，以证明该计划正在有效地实施，并且客户正在收到好处。局外人的观点，甚至那些可能被视为对手的人，在制定替代方案时也同样重要。这一进程正在进行中。 项目灵活性是整合新发现和保持共识的关键因素。因此，销售基础设施更换计划可以归结为三种努力:发现、建立共识和灵活性。

Throughout the review and establishment of a proposed infrastructure replacement program, the importance of sound data cannot be over emphasized. The engineering aspects as well as the financial aspects of pipeline maintenance and replacement require an extreme amount of coordinated effort to substantiate that a replacement program is needed and to aid in planning the program. The author believes that the data will be even more important as we go into the future to demonstrate that the program is being done efficiently and that benefits are being received by the customers. The viewpoints of outsiders, even those who may be considered adversaries, are equally important in fashioning a replacement program. This process is ongoing. Program flexibility is a key ingredient to incorporate new discoveries and maintain consensus. Selling an infrastructure replacement program, then, comes down to three efforts: discovery, consensus building, and flexibility.
