Project BackgroundData collection Respondents • 4,390 responses were received • 4,390 responses were used for modeling Those who answered for more than one data center: Two: 134 Three: 12 Four: 2 Five: 1 E-mail addresses from lists associated with some of the data centers were included to reach the large number of users who may have accessed data via anonymous ftp.
Project BackgroundRespondent information Demographics (when comparable) remain fairly consistent with 2009 For which specific areas do you need or use Earth science data and services? * Multi-select question; Answer choices added in 2010; Language to question was changed slightly in 2009; Modeling was asked as a separate question prior to 2008

NASA EOSDIS Benchmarks Strong performance continues … ACSI (Overall) is updated on a quarterly basis, with specific industries/sectors measured annually. Federal Government (Overall) is updated on an annual basis and data collection is done in Q3. Quarterly scores are based on a calendar timeframe: Q1- Jan through March; Q2 – April through June; Q3 – July through Sept.; Q4 – Oct. through Dec.
NASA EOSDIS ModelProduct Search/Selection/Documentation and Customer Support most critical Scores The performance of each component on a 0 to 100 scale. Component scores are made up of the weighted average of the corresponding survey questions. Impacts The change in target variable that results from a five point change in a component score. For example, a 5-point gain in Product Search would yield a 1.0-point improvement in Satisfaction.
NASA EOSDIS 2007 – 2010 Significant changes from 2009 (+/-) 0.4 (+/-) 0.8 (+/-) 0.5 (+/-) 0.5 (+/-) 0.5 (+/-) 0.5 (+/-) 0.5 =Significant Difference vs. 2009
Areas of Opportunity for NASA EOSDIS Remain consistent year over year Top Improvement Priority Product Search (76) Product Selection and Order (77) Product Documentation (76)
Score ComparisonSame CSI inside and outside the USA 73% of respondents are outside of the USA in 2010 vs. 71% in 2009. Respondents outside the USA have the same Satisfaction score with EOSDIS (77). Compared to last year there was no score change for those respondents within the USA and a one-point score increase for those respondents outside the USA.

Product DocumentationData product description most sought after What documentation did you use or were you looking for? Data product description 78% Product format 66% Science algorithm 49% Instrument specifications 44% Tools 40% Science applications 30% Production code 12% CSI for those whose documentation was not found is 70 vs. those who got it delivered with the data (77) or online (78). Was the documentation… Delivered with the data (18% vs. 18% in ‘09) Available online (75% vs. 73% in ‘09) Not found (7% vs. 9% in ‘09) Impact=1.0 =Significant Difference vs. 2009
Product DocumentationScores by data center (+/-) 2.2 (+/-) 3.0 (+/-) 2.6 (+/-) 2.7 (+/-) 4.1 (+/-) 0.8 (+/-) 1.3 (+/-) 1.6 (+/-) 1.9 (+/-) 2.6 (+/-) 2.4 (+/-) 3.3 =Significant Difference vs. 2009
Customer SupportMaintain strong performance 88% (89% in 2009) were able to get help on first request. These respondents continue to have a significantly higher CSI (82) than those who did not (66). Did you request assistance from the Data Center’s user services staff during the past year? No=75%. Of those who said yes, 87% used email, 2% used the phone, and 11% used both phone and e-mail. Impact=1.5 =Significant Difference vs. 2009
Product QualityPreferences in line with actual for the most part In 2009, 58% said products were provided in HDF-EOS and HDF and 44% said they were their preferred method. *Multiple responses allowed
Product QualityMaintains score this year Impact=0.5 =Significant Difference vs. 2009
DeliveryDrops one point this year Over half said their data came from MODIS (same in 2009) 28% said ASTER (27% in 2009) *Multi-Select Impact=0.6 =Significant Difference vs. 2009
DeliveryMethods for receiving … 73% said FTP was their preferred method in 2009 How long did it take to receive your data products? 23% immediate retrieve CSI=81 20% less than 1 hour CSI=78 27% less than a day CSI=76 23% 1-3 days CSI=76 4% 4-7 days CSI=75 2% more than 7 days CSI=69
Customers over multiple yearsWho have answered the survey multiple years … No significant differences were seen between 2009 and 2010 for those who have answered the survey over the last four years. For those answering the survey over multiple years, most scores have seen some positive movement (Difference refers to 2010 vs. 2009)
Customers over the past two years Who answered the survey in 2009 and 2010 For those answering the survey in 2009 and 2010, there are a number of statistically significant score differences. (Difference refers to 2010 vs. 2009)
Customers over the past three yearsWho answered the survey in 2008, 2009 and 2010 For those answering the survey in 2008, 2009 and 2010 there were no statistically significant score differences between 2009 to 2010. (Difference refers to 2010 vs. 2009)
Summary • NASA EOSDIS has made significant improvements versus last year in a couple of areas (Product Search and Product Selection and Order) • Delivery and Product Documentation both saw a small but significant decrease this year • Product Search, Selection and Order continue to be the top opportunities for improvement • Documentation also continues to be a top opportunity • Customer Support continues to be high impact for those who use it. Imperative to maintain the strong level of service. • Ensure those who are providing it realize how it affects satisfaction

A Note About Score Calculation • Attributes (questions on the survey) are typically answered on a 1-10 scale • Social science research shows 7-10 response categories are optimal • Customers are familiar with a 10 point scale • Before being reported, scores are transformed from a 1-10 to a 0-100 scale • The transformation is strictly algebraic; e.g. • The 0-100 scale simplifies reporting: • Often no need to report many, if any, decimal places • 0-100 scale is useful as a management tool
Deriving Impacts • Remember high school algebra? The general formula for a line is: y = mx + b • The basic idea is that x is a “cause” and y is an “effect”, and m represents the slope of the line – summarizing the relationship between x & y • CFI Group uses a sophisticated variation of the advanced statistical tool, Partial Least Squares (PLS) Regression, to determine impacts when many different causes (i.e., quality components) simultaneously effect an outcome (e.g., Customer Satisfaction)
