61 APPENDIX A State and Provincial Agency Survey Questionnaire Quality Management of Pavement Data Collection Survey Questionnaire for NCHRP Synthesis Topic 39-01 One of the most costly parts of operating a pavement management system relates to collecting network- level pavement condition information, and agencies are faced with developing procedures and guidelines for quality management of these activities. Agencies using contractor-provided services for pavement data collection have had to develop methods for contractor selection, monitoring during the contract period, and data acceptance. Agencies using staff resources for pavement data collection have had to develop similar quality control activities which include training of their staff. The objective of this survey is to support the development of a synthesis project aimed at documenting quality management practices employed by public road and highway agencies for automated, semi- automated and network-level manual pavement condition data collection and delivery. The synthesis will document: (1) the quality management techniques used in contractor selection, monitoring, and data acceptance by agencies that outsource the data collection; (2) the quality management techniques used for operations by in-house staff including training, certification, monitoring, and data acceptance in agencies that conduct these efforts internally; and (3) how these practices have impacted the quality of the decisions made based on the data collected. The survey consists of three types of questions: fill in the blank, chose one, and multiple choice. In the fill in the blank questions, please type the adequate answer. A choose one question allows you to choose only one response from the available response options. In the multiple choice questions you may mark/check more than one box as appropriate. Since the survey is “dynamic,” you may notice that it skips some questions that are not relevant to your agency. For example, if you do not indicate that you are contracting some of the data collection activities, the survey will not display the questions on quality assurance of the delivered data. The survey has persistence if you have the cookies allowed option turned on in your computer; your response will be stored each time you press the Next Page button. Unfortunately, your stored responses will not be accessible from other computers. If this survey would be better answered by somebody else within your office, please feel free to forward it to that individual. DEFINITIONS: The following definitions are important to complete this survey. Quality Assurance: All those planned and systematic actions necessary to provide confidence that a product or facility will perform satisfactorily in service. For purposes of this survey, quality assurance activities are those that govern the acceptance of the data. Quality Control: Those actions and considerations necessary to assess and adjust production processes so as to control the level of quality being produced in the end product. It is also called process control. For purposes of this survey, quality control activities are those used to control the data collection activities, either by a data collection contractor or a road agency collecting data in-house. Quality Management: The overarching system of policies and procedures that govern the performance of quality assurance and control activities; i.e., the totality of the effort to ensure quality in the data. Please complete the electronic survey by Saturday, March 15, 2008 If you have any questions, please contact: Gerardo Flintsch, e-mail: flintsch@vt.edu, Tel: 540-231-9748.
