The interpretation and application of the improvement recommendations will vary amongst DOTs based on size, organizational structure, leadership objectives, and other factors.
However, by complementing improvement recommendations with real project examples aligned with various areas of the assessment, DOTs will be able to see how others have approached similar challenges, how those challenges were addressed and how desired outcomes were achieved.
Each case study is is provided in a consistent format. This format provides the reader a concise and clear description of why the project was undertaken, the approach applied, the value delivered, and the key challenges faced. Supporting graphics are included with each case study to provide visual context in the form of charts, workflows, screen captures or other artifacts.
The motivation section of the case study is designed to create a relatable position for why a DOT would undertake such a project. The goal of the motivation description is to help the reader identify with the originating challenge or opportunity and related it to a similar challenge or opportunity within their own organization.
The approach is intended to provide a high-level walkthrough of the key steps the DOT took to execute the project or initiative. Specific step, actions, tactics and engagement strategies employed by the DOT are detailed as applicable.
In the value delivered section, the outcome of the project or initiative is described in qualitative or quantitative fashion. By providing the outcome value information the reader can infer similar outcome value propositions for improvements that they are considering that might be associated with the particular case study.
Key Challenges Faced
Each case study highlights key organizational requirements and challenges faced during implementation. Each case study categorizes these challenges by time, resources, expertise, coordination, and change.
Supporting Graphics and Context
In order to bring the project or initiative to life, select images are provided to support the textural portion of the case study. These images may be photographs, screen shots or applications, charts, or other representative graphics to help illustrate motivation, approach, value or challenges.
Case study selection is guided by an understanding of some of the more challenging and progressive areas of the guidance. Each case study is aligned to an assessment area with a single case study potentially covering more than one area or element.
Below are listed the case studies organized by assessment area, section and/or element references identified. A brief case study description outlines how the case study provides a useful example of practice and how it is linked to the assessment and improvement framework.
Detailed case study materials are found in Appendix G.
