Component scores are made up of the weighted average of the corresponding survey questions. Scores 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 0.9-point improvement in Satisfaction.

25 © CFI Group 2011 Customer Support Maintain great performance 91% (88% in 2010) were able to get help on first request. These respondents continue to have a significantly higher CSI (81) than those who did not (66). Impact=1.7 Did you request assistance from the Data Center’s user services staff during the past year? No=76%. Of those who said yes, 80% used , 2% used the phone, and 10% used both phone and Customer Support Professionalism Technical knowledge Accuracy of information provided Helpfulness in selecting data or products Timeliness of response Helpfulness in correcting a problem

26 © CFI Group 2011 Product Quality Preferences somewhat in line with what provided ~Multiple responses allowed In 2010, 57% said products were provided in HDF-EOS and HDF and 42% said they were their preferred method. GeoTIFF is most preferred format, while HDF-EOS/HDF is format in which products were provided the most. Only 8% of products provided in GIS although nearly one-quarter prefer that format.

30 © CFI Group 2011 Summary

31 © CFI Group 2011 Summary  Satisfaction with NASA EOSDIS has held at 77 for four years. NASA continues to meet data users needs.  As would be expected with consistent satisfaction scores, there were very few changes in drivers’ scores. Half of the drivers had no change and any changes in satisfaction drivers were no more than one point. Delivery and Product Quality improved one point, while Product Search was down one point. There was no change in Customer Support, Product Selection and Order, and Product Documentation. However, due to the large sample size a one-point change is statistically significant at a 90% confidence level.  While scores are solid, there are opportunities to improve. Product Search, Selection and Order, and Documentation continue to be the top priorities. Work to refine and improve the search capabilities and functionality. Continue to clarify descriptions of data products, and make language easy to understand. As some respondents are still having difficulty locating documentation, continue to work on both providing accessible and clear documentation that is readily available for users.

32 © CFI Group 2011 Summary  Customer Support remains the top scoring area. As it is also the highest impact area, it is important to maintain the great level of service and support already being provided. Share the importance and impact of customer support with those providing it, to help boost awareness. Look for areas of best practice among top performing data centers, to ensure all centers are providing high levels of service.  GeoTIFF and GIS appear to have a higher preference by customers than what was provided. NASA should explore offering more data products in these formats.

34 © CFI Group 2011 Customers over multiple years Who have answered the survey multiple years … No significant differences were seen between 2010 and 2011 for those who have answered the survey over the last four years. For those answering the survey over multiple years, score movement is mixed. (Difference refers to 2011 vs. 2010)

35 © CFI Group 2011 Customers over the past three years Who answered the survey in 2009, 2010 and 2011 For those answering the survey in 2009, 2010 and 2011, there are no statistically significant score differences. (Difference refers to 2011 vs. 2010)

36 © CFI Group 2011 Customers over the past two years Who answered the survey in 2010 and 2011 For those answering the survey in 2011 and 2010, there are a number of statistically significant positive score differences. (Difference refers to 2011 vs. 2010)

38 © CFI Group 2011 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 scale –The transformation is strictly algebraic; e.g. –The scale simplifies reporting: Often no need to report many, if any, decimal places scale is useful as a management tool

39 © CFI Group 2011 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)
