This book addresses a generic methodology for quantifying the benefits of Asset Management Systems (AMS) implementation and justifying investment in AMS implementation based on literature review and case studies that focus on road performances. The case studies suggested that AMS implementation contributes to an improvement in transportation agencies' performance and costs for maintenance and rehabilitation, and that the benefits derived from AMS implementation exceed costs for AMS implementation and operation. In addition, this book identifies barriers and needs in AMS implementation process and illustrates a strategic direction for successful AMS implementation based on literature review as well as the Soft Systems Methodology, which exposes barriers and needs from inside a hypothetical transportation agency.
