APPENDIX B
Service Providers 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. 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 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. 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 company, 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.
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 cob Monday, April 15, 2008
