Constituent Service Quality Survey (CSQS)

Introduction
Extensive research in the past 20 years has shown that high-performance organizations identify several factors as necessary for success. Not surprisingly, customer satisfaction is often considered the most important. Only by knowing what customers (constituents) want from an organization can that organization confidently plan and manage its resources and performance.

The importance of customer satisfaction was demonstrated by the National Quality Initiative (NQI), which acted to establish a database of customer needs and expectations at the national level. To date, more than 20 state departments of transportation have followed the NQI effort and surveyed constituents concerning their needs and expectations at the state level.

Based on the NQI model, MoDOT conducted a statewide telephone survey to assess customer perception of the quality of services MoDOT provides. Survey results and data analysis aid in measuring our efforts to meet customer expectations and serve as a baseline database from which to assess the department's progress in meeting their needs and expectations.

Research Approach
A multidisciplinary team was formed to direct the study. It included employees with backgrounds in community development, research methods, sociology, public involvement, planning and engineering. The team worked with the University of Missouri Department of Rural Sociology to identify relevant performance areas and data collection and analysis methods. The purpose of the research was refined to establish a baseline of customer service and performance and to evaluate MoDOT's effectiveness in meeting customer expectations for quality transportation services.

The study was expected to provide information on customer perception of performance, information to refine operations and services, a benchmark for future research, information to guide planning efforts, and a system of performance management based on the replication of the research. The CSQS research project design consisted of a literature review including other recent NQI efforts, internal and external stakeholder interviews, project review and buy-in by stakeholders and the constituent telephone survey.

MoDOT determined a telephone survey of the state's residents would be the most cost effective and successful means to collect the data needed to develop a statistically valid and reliable database. The survey consisted of 1,581 completed telephone surveys with randomly selected Missourians. The data was collected on a statewide and regional basis facilitating comparisons between the St. Louis Region (4 counties), the Kansas City Region (5 counties) and the rest of the state. This approach allows for a 95 percent confidence level and a maximum sampling error of plus or minus 3 percent for each region and the state as a whole. The elements of the telephone survey included demographic information and transportation use characteristics of the respondent, quality ratings and future priority ratings for transportation system characteristics, and an evaluation of project rating criteria.

Results
The focus of the research analysis involved a set of 41 questions covering all aspects of Missouri transportation, including road conditions and markings, availability of a variety of transportation options, highway construction and maintenance, safety issues and customer service. The forty-first question was about light rail service and only applied to the St Louis area. A discrepancy analysis was used to examine the 41 performance items on the survey questionnaire. Discrepancy analysis is commonly used in helping make decisions about priorities in performance management.

A discrepancy analysis consists of a comparison of the customer's perceptions of the quality of a service currently provided and what level of effort should be expended toward that service in the future. The discrepancy between the evaluation of current satisfaction and expectations of performance in the future identifies services that are a concern for the department, a strength of the department, or a service on which customers feel MoDOT spends more resources than needed.

Of the 41 variables included in the research, 29 of the variables measured were determined to be "strengths"; the remaining 12 items were determined to be "challenges" for the department. The following bar chart identifies the 40 statewide measures used and the discrepancy between the satisfaction and importance for each issue. Items on the left side of the chart represent areas where customers report their current satisfaction is greater than the need for future attention. Variables listed on the right side of the chart are areas that customers report needs greater future attention.

Interestingly, there are items where the public thinks MoDOT is doing better than their importance warrants. These items are shown on the far left side of the bar chart. These include items such as setting speed limits, use of work zone signs, maintaining rest area facilities and providing for regional airports. Conversely, the findings indicate that pavements are the primary concern of Missourians as shown on the far right side of the bar chart. Three of the top items identified as needing improvement include providing pavement that lasts a long time, maintaining the pavement to provide a smooth ride, and repairing pavement surfaces promptly. Other items that were identified as needing more effort included project planning, and the allocation of resources.

31. Providing Amtrak passenger rail service to meet your needs
32. Planning a project in a reasonable amount of time
33. Completing road and bridge construction and repairs in a timely manner
34. Providing the public with adequate opportunities for input in project planning
35. Distributing transportation funds fairly to all areas of the state
36. Using public funds in a cost effective manner
37. Providing pavement that lasts a long time
38. Maintaining the pavement so it provides a smooth ride
39. Repairing pavement surface promptly
40. Providing pedestrian / bicycle pathways on or adjacent to highways that are safe.
41. Provide light rail such as MetroLink (St. Louis only, not plotted on this statewide graph).

Besides the discrepancy analysis, the CSQS report includes a variety of analyzes including significance testing for regional differences and relationships between the variables, demographic profiles, as well as frequency reports. For example, for most items in the survey, the regions are far more similar than they are different. Additionally, the demographic characteristics of the survey respondents' are largely representative of the state as a whole.

The report also indicates that respondents prefer greater attention to maintenance and preservation activities rather than expansion of the system. The survey reports that respondents would devote 60 percent of MoDOT's budget to preservation and 40 percent to new construction. The full report breaks all of the research focus areas down and presents a thorough analysis of the CSQS database.

Implementation
The information provided by the CSQS report will serve MoDOT well as we consider how to allocate future resources to meet the needs of our customers. The information has already been incorporated into the long-range planning process. Additionally, the success of this effort has lead to greater use of customer surveys and non-traditional methods of acquiring input on customer satisfaction. As the CSQS project was designed as a baseline effort, we are now preparing to complete the research effort on a 3 to 5 year basis. We found that the CSQS effort has provided valuable information for planning and operations management as well as communicating to the state's residents that MoDOT wants to know what the public thinks.
