Since ease of implementation was evaluated separately for technical implementation and UX design, the scores for those two aspects were combined to determine a total ease of implementation score. These estimates of value to the user and ease of implementation were combined to provide a final score. These are expressed on a scale of 1-10 where 10 is easiest to implement. In order to facilitate comparison, estimates of implementation effort were converted to ease of implementation. Estimates of the effort for user experience design were added by Suzanne Chapman of the University of Michigan who will be the lead for UX design for the implementation. The implementation effort will also include considerable effort in user experience design. These estimates were made by Tom Burton-West of the University of Michigan who will have primary responsibility for implementing the features. The emphasis of the charge on features that can be added quickly without requiring additional resources led us to include estimates of the implementation effort. After a number of group discussions about the features, each member of the group did a final rating of estimated value to users on a scale of 1-10, and the average value is what is reported in the chart on the following page. We then did a preliminary rating of value to users based on our collective knowledge of user needs, information-seeking behavior, user behavior, and usability principles. The group started by brainstorming and listing features and functions believed to be of high value to users. The body of the report gives a detailed description of the features and lists the rationale for including each feature, as well as applicable user-centered design principles and implementation issues that may have an impact either on implementation effort or usability. The chart below gives a brief description of potential features that meet these criteria and provides estimates for each of the three following areas: value to users, ease of implementation, and ease of user experience (UX) design. The charge of the HathiTrust Full-Text Search working group is to examine the HathiTrust Full-Text search application and "identify and prioritize features and functions anticipated to have immediate high-impact value to users that can be reasonably afforded by the existing technology framework."
