Guidance for Implementing a Cross-Asset Resource Allocation Approach 51 There are many ways to either broaden or narrow the scope of the allocation approach to best fit the goals of the agency. Check the examples in the call-out box to see how other agencies defined the scope of their resource allocation approach.

52 Case Studies in Implementing Cross-Asset, Multi-Objective Resource Allocation Examples: Defining Goals and Objectives Caltrans adapted the goals listed in its Strategic Management Plan for 2015–2020 for use in its resource allocation methodology. Not all of the goals in the Strategic Management Plan were applicable to the prioritization of preservation projects, so some adjustments and reconfiguring were needed to ensure the goals represented what the agency sought to accomplish with the projects.

Guidance for Implementing a Cross-Asset Resource Allocation Approach 59 Example: Using a Spreadsheet When using a spreadsheet to prototype your cross-asset resource allocation approach, it is important to ensure that it can be used to communicate the approach to others. In particular, it should be developed in a way that decision makers can understand the scores and see the results.
