Policy-Driven. TAM should capture and respond to policy objectives, and provide meaningful information about how changes in the transportation system support these objectives. A TAM policy can set boundaries, clarify intent, and communicate the scope of a TAM program including types of assets that will be managed and what work activities to emphasize.. [NCHRP 551]
Performance-Based. TAM should have concrete objectives that are translated into system performance measures used for both day-to-day operation and longer-term strategic management. The use of performance data to support the management of assets enables agencies to select and deliver projects that achieve its objectives. Transparent processes allow for accountability to both internal and external stakeholders.
Risk-Based. Risk management plays a role in resource allocation, project selection, long-term planning and other essential parts of the TAM process. As such, an organization’s approach to risk management and the outcomes resulting from a risk assessment have important implications for TAM. An agency must establish a risk management approach and integrate risk management in TAM planning and decision making.
Strategically Aligned with Agency Priorities. TAM measures should be aligned with agency priorities and goals to ensure that investments made to extend asset service life provide the maximum impact to achieve long-term goals. Connecting performance measures to higher level strategic goals also supports an agency’s ability to communicate to customers and stakeholders how technical measures relate to system performance.
Transparent. TAM planning and results should be monitored and reported for both impact and effectiveness. Feedback on actual performance should influence agency goals and objectives, as well as future resource allocation and project decisions. Transparency and agency accountability are key in ensuring the long-term support of project partners, customers and stakeholders.
Information-Driven/Evidence-Based. Strategic decisions with respect to agency goals and TAM objectives should be evaluated using credible and current data. Decision support tools such as management systems should be applied to help in accessing, analyzing and tracking data, and must be an integral part of business and decision processes. Data requirements for performance measures should be realistic and feasible. [NCHRP 551]
Option Oriented. By taking a structured and repeatable approach to TAM decision-making, an organization improves its own resilience and ensures that it will continue to succeed even as new challenges arise and personnel changes over time.
Continuously Improved. TAM processes should provide managers with sufficient information to understand problems and suggest solutions. The agency should be committed to regular, ongoing processes of monitoring and reporting results in order to identify and implement improvements to system performance or further the effectiveness of TAM.
