Using the Tool
This subsection introduces the TAM Gap Analysis Tool designed for agencies to self-assess their Transportation Asset Management (TAM) practices. It outlines the tool's purpose, administration process, and the flexibility it offers in tailoring assessments to agency needs. Additionally, the document provides a checklist suggesting strategies for addressing identified gaps and advancing agency practices based on the gap analysis results across different TAM focus areas.
Note: This subsection was derived from the AASHTO TAM Portal. Copies of the TAM Gap Analysis Tool, User Guides, and additional information are available here: https://www.tam-portal.com/tool/tam-gap-analysis-tool-nchrp-08-90/
Overview
A gap analysis is administered by an individual within the agency who is responsible for identifying participants, determining what part of the assessment each participant will receive, distributing links to the assessment to each participant, and compiling the results. As detailed in the User’s Guide, the TAM Gap Analysis Tool provides agencies flexibility in using the survey as it’s designed, or reducing the survey length by eliminating Elements or Criteria that may not be relevant. There is also flexibility in determining which parts of the assessment are appropriate for each participant. For instance, individuals associated with data collection may only be asked to evaluate the criteria related to Assessment Area 4, Data Management.
Individualized links are distributed to each participant to complete the assessment. Assessment participants are required to log into the web-based tool (using their email address). Once logged in, the participants are able to access the assessment, where they are asked to rate the agency’s current practices in comparison to each Criterion using a 5-point rating scale. Optional fields are provided for notes that a participant may want to make to explain their response. In addition to rating the agency’s current practices, the tool allows the agency to set a desired, or targeted, rating for each criterion using the 5-point scale.
After all assessments are completed, the results are compiled and presented as graphs, spider diagrams, and tables. Results can be compiled at the agency level or by any subset of the raters. Results can also be presented at the Assessment Area, Element, or Criteria level depending on the agency’s needs. To facilitate reporting, results can also be exported in spreadsheet format for external reference and use.
