TPM Relationship with TAM

There is a close relationship between TPM and TAM, since both consider asset and system performance, risks and available resources to achieve desired objectives over time. Both rely on a strategic approach, using data to make investment and policy decisions in order to achieve performance objectives. Internationally, there is less distinction between asset management and performance management, with the IAM defining asset management as encompassing the “balancing of cost, opportunities and risks against the desired performance of assets to achieve the organizational objectives.” In the United States, TAM applies to the technical and financial decisions, plans and actions related to physical infrastructure, while TPM considers a broad range of system performance categories.

A graphic illustrating the integration of asset management and performance management is provided in Figure 2-4. In the figure, the circle on the left represents the interconnection of the various performance areas that transportation agencies are concerned with throughout their planning processes. Flowing into the performance circle is the asset management circle, representing an agency’s infrastructure needs to support system performance.

The FHWA’s Expert Task Group (ETG) published a white paper explaining the relationship between asset management and performance management. It acknowledges the performance of a transportation system is dependent on many factors, including operational characteristics, and system usage and demand, in addition to the physical condition of the infrastructure assets. The paper explains that “performance management focuses on how policies, resource allocation, and other decisions affect all aspects of system performance including safety, operations, environmental stewardship, and infrastructure condition.” (FHWA 2012) Asset management is described as an application of performance management principles with a long-term focus to manage the performance of infrastructure assets, the resources allocated to operate a transportation system, and the investments made to achieve the agency’s long-term goals and objectives.
