TAM Elements Overview

Monitoring the state of the assets and developing desired and expected Levels of Service (LoS). Performance measures are used to align agency investment decisions with organizational objectives, such as asset condition or system reliability, and to monitor progress towards achieving agency goals. In TAM, asset performance is most commonly defined in terms of asset condition or maintenance LoS. LoS provides the link between agency goals and the investments and interventions that should take priority when managing assets.

Maximizing use of available revenues. Agencies are faced with the problem of determining how to divide scarce resources between different asset types, in order to accomplish a variety of different objectives. TAM planning offers processes to help make these resource allocation decisions, such as Multi-Objective Decision Analysis (MODA), long term financial planning, and Life-Cycle Planning.

Monitoring and managing risk. In TAM, uncertainty complicates efforts to make decisions about the future and forces agencies to be nimble so as to effectively respond to unpredictable events and evolving conditions. An organization’s approach to risk management and the outcomes resulting from a risk assessment have implications for TAM. It is important to establish processes to track changes in risks over time and monitor actions taken to manage risks, through tools such as a risk register and/or a risk mitigation plan.

Investing in asset maintenance. State DOTs can specify their desired SGR, consistent with their TAM objectives, for the 10-year analysis period of their TAMP. This strategic long-term maintenance strategy helps agencies minimize the life cycle costs of preserving assets, while also managing asset performance to a defined target to the extent practicable with available resources.

Understanding the potential for asset failure and developing intervention strategies. Being aware of the potential for asset failure and making strategic investment decisions can help agencies prevent failures, reduce costs, and maintain a desired level of service. Over an asset lifecycle, a range of interventions are possible, from reactive, routine and preventative maintenance, to large investment associated with renewal, replacement and disposal.

Allocating resources and prioritizing work based on both short and long-term performance. The resource allocation process should support achieving short- and long-term goals. An agency must establish what scarce resources must be allocated, and what the constraints on these resources are. A key part of the process is to translate goals and objectives into performance measures so the agency can set target values for key measures and/or establish a target level of service.

Continuous improvement based on feedback. An agency should have regular, ongoing processes of monitoring and reporting results in order to identify and implement improvements to system performance or further the effectiveness of the performance management process. Ongoing monitoring, improvement and/or problem identification should be incorporated into the planning process to help adjust and determine future targets and processes.

Aligning the organization. Successful TAM depends on the alignment of a diverse set of internal business units and external partners and stakeholders. Strategic coordination and communication can bring these people and groups together to achieve TAM goals. In addition, the choice of a TAM organization model is important, and should align with and support agency policies and priorities.
