Resource allocation decisions are based on a well-defined and explicitly stated set of policy goals and objectives. C H A P T E R 2 Interstate Asset Management Framework

Once an initial set of goals and objectives has been established, the next step is to analyze options and tradeoffs. In this step, analytical tools are used to systematically analyze the impact of different budget levels for a specific set of assets and activities.

Generic asset management process with issues of importance for the IHS. • Customer expectations • Response to program implementation • Use analytical tools to analyze the impact of different funding levels on system performance • Incorporate risk assessment results • Consider tradeoffs between preservation, mobility, safety, environment, and other areas • Monitor and report performance results • Collect and manage data for accountability and feedback • Evaluate delivery alternatives • Keep all stakeholders updated on delivery status • Determine strategy for developing programs and prioritizing projects • Define the role of the stakeholders in the resource allocation process • Finalize budget allocations • Establish goals and objectives for IHS assets • Select the performance measures • Set performance targets Policy Goals and Objectives Analysis of Options and Tradeoffs Resource Allocation Decisions Program and Service Delivery System Conditions and Service Levels Funding Levels Customer Input

In another respect, the objective is quite broad, as it implies consideration of the full range of factors that might impact operation of the IHS, and introduces the concept of a national interest in IHS asset performance. This approach provides a consistent asset management framework and performance expectations for the IHS by leveraging existing agency-to-agency institutions and relationships in managing the connection points of the system.

The basic strategy recommended for integrating decision making for IHS assets with the broader decision-making scope presented here is for each IHS owner to develop an Interstate Asset Management Plan on a periodic basis. The plan should summarize conditions of IHS assets, establish performance measures for those assets considering available funds, and describe the plan for future investments in the IHS.

With regard to other assets beside pavement and bridges, the guidance can be summarized as follows: • IHS owners should collect inventory and inspection data for IHS pavements and bridges consistent with both Federal reporting requirements and the requirements of pavement and bridge management systems, and they should use these systems to manage pavements and bridges. • IHS owners should collect inventory and inspection data for all of their IHS structures, including those listed in Table 2.1.

With regard to the Environment category, it is clear that this is an area of great importance, but there are few environmental measures that can be both localized to the IHS, and used to support the asset management process. Also, there is little consistency from one IHS owner to another concerning how environmental data are collected and reported.

The starting point for developing the Interstate Asset Management Plan should be an agency's existing long-range plan (LRP) developed following the Federally mandated LRP development process.

It should serve as guidance for subsequent programming and project prioritization processes, and provide a basis for monitoring the effectiveness of investment decisions in terms of the defined targets. Since resources are invariably limited and insufficient to achieve all desired outcomes, the "art" of asset management comes into play when all of the information and analyses are focused on evaluating an array of "what if" investment alternatives that consider vulnerabilities and deficiencies, risks and priorities, goals and performance targets.
