EOSDIS Survey Overview

  1. 1. EOSDIS Survey Overview Carol.L.Boquist@nasa.gov HDF and HDF-EOS Workshop Nov. 4, 2009
  2. 2. Why we survey NASA’s Earth Observing System Data and Information System provides data products and associated services for interdisciplinary studies to a diverse user community. Beginning in 2004, the Earth Science Data and Information System (ESDIS) Project has conducted annual surveys to measure user satisfaction using the American Customer Satisfaction Index (ACSI). The results are one of the ESDIS Project’s metrics sent to the Office of Management and Budget (OMB).
  3. 3. The Easy Part We start by setting up an Interagency Agreement between NASA and the Department of Interior. The survey is conducted by CFI Group under contract with the Federal Consulting Group (FCG) of Department of Interior’s National Business Center. The FCG is Executive Agent in government for the ACSI. They work with OMB to ensure adherence to applicable Federal regulations such as the Privacy Act and the Paperwork Reduction Act.

  7. 7. Who do we survey? E-mail addresses are obtained from: •Orders from registered users •Inquiries •Anonymous FTP access •Data center lists The number of e-mail addresses per data center varies greatly because the data centers vary greatly: •Discipline-specific •Number or frequency of available products •Size of user communities •Number of anonymous ftp users •Restricted access or cost Multiple invitations to the same user •A user with multiple e-mail addresses will receive multiple invitations •A user accessing multiple data centers will receive multiple invitations
  8. 8. Survey Questions The survey contains comment fields and several types of questions: • Demographic questions • Questions to aid recall • Rating questions for the ACSI and EOSDIS models • Non-modeled rating questions The questions were originally based on a previous survey of the members of the User Working Group for each of the data centers. Formulating the questions is a combined effort of project personnel, EOSDIS User Services Working Group (USWG), and the CFI Group. The challenge is to keep the survey short enough so users are willing to respond, yet long enough to reflect the complexity of the data and differences in data centers, and more importantly, understand the needs of the diverse user community.
  9. 9. How did EOSDIS Compare in 2008? The ACSI is the #1 national economic indicator of customer satisfaction. The ACSI is produced by the Stephen M. Ross Business School at the University of Michigan, in partnership with the American Society for Quality (ASQ) and the international consulting firm, CFI Group. The ACSI is used to measure over 40 industries and 200 organizations covering 45% of the U.S. economy. Over 70 U.S. Federal Government agencies have used the ACSI to measure more than 120 programs/services.
  10. 10. Survey Results 2004-2008 Although the survey contains over 50 questions, the ACSI is based on responses for only three questions. N= number of responses used (sample size). See Slide 9 for confidence levels.
  11. 11. The EOSDIS Model 2008 Results and Priorities A series of questions are asked for each of the 6 elements of the EOSDIS model: •Product Search •Product Selection and Order •Delivery •Product Quality •Product Documentation •Customer support CFI’s methodology quantifiably measures and links satisfaction levels to performance and prioritizes actions for improvement.
