AssetManager NT provides a motivation and a framework for running individual management systems in a consistent, coordinated way that supports tradeoff analysis. Over time, it may serve as the catalyst for enhancing management systems to produce performance measures that better allow for comparison of investments across asset types.

The what-if tool provides interactive on-screen views of the relationship between investment levels and performance measures by investment category. Four views are provided for what-if analysis: • The budget view allows the user to explore the relationship between the average level of investment over time and the value of a single performance measure for a selected asset and portion of the network.

the allocation of resources across geographic and network subsets. 2.3 The tool shall allow users to set a target value for a performance measure for the network as a whole at the end of a selected time horizon and to see what annual expenditure level would be required to meet that performance target.

This user interface eliminates the need for users to edit the configuration text file; however, this text file is still part of the system. 5.2 The tool shall allow the user to maintain an unlimited number of sets of configuration information, each of which can specify different asset classes, network and geographic subsets, weighting factors, and performance measures.

For agencies that routinely use benefit/cost analysis tools for significant numbers of projects, utility programs could be developed to extract results data. (Agencies that do not have benefit/cost tools in place can Figure 6.

; • Expenditures by project type for a budget scenario (in tabular and bar chart form) , which allows filtering by geographic and network category; • Amount of work by type compared to established work targets for a budget scenario or comparison across budget scenarios (in tabular form)

A combination of a geographic category and a network category. Performance measures may be summarized for each system subset.

From page 46... ...
Project impacts can only include values for performance measures that are on this master list. Similarly, system measures reported for projects must match the system measures associated with the reported performance measures for the projects.
|
From page 47... ...
Each project type may be assigned a type of system measure for purposes of tracking work to be accomplished in the program against established targets. 1.5 The tool shall construct pick lists from the standard performance measures, system measures, network categories, geographic categories, system subsets, project types, and asset types to ensure consistency in data entry of project and system information.
|
From page 48... ...
6.2 The tool shall produce a pie chart showing the distribution of program resources by budget category and a bar chart showing the budgeted and allocated program resources by budget category. 6.3 The tool shall produce a report showing the projected versus target values of performance measures for each system subset.
