    Usage Of Enterprise File Sharing Service   Muller   Chi 2010 Usage Of Enterprise File Sharing Service Muller Chi 2010 Presentation Transcript

    • Patterns of Usage in an Enterprise File-Sharing Service: Publicizing, Discovering, & Telling the News Michael Muller, David R Millen, & Jonathan Feinberg* IBM Research / Collaborative User Experience IBM Center for Social Software Cambridge, MA, USA * Jonathan Feinberg is now at Google. IBM Research 1
    • Agenda • File-sharing in an enterprise • Factor analysis of file-sharing usage patterns – Upload & Publicize – Annotate & Watch – Discover & Tell – Refind • Interpretation – Both more and less social than anticipated – Design what and for whom? – Who is missing? Future analyses IBM Research 2
    • File-Sharing in an Enterprise • Cattail, an enterprise file-sharing service – Centralized – Authenticated for all access – Simpler than peer-to-peer or public networks • Cattail statistical profile – Users 88270 (many job roles, 80 countries) – Uploaders15943 (18%) – Files 120288 (diverse formats) – Downloads 728509 • Related work – Dropbox / UD Dropbox (Schwartz, 2007) – Apocrita (Reynolds et al., 2005) – Studies of file-sharing (Christin et al., 2005; Lee, 2003; Rader, 2009; Voida et al., 2006; Whalen et al., 2008) IBM Research 3
    • Cattail Features and Capabilities • Capabilities – Upload – Share (recommend) * – Download * – Collect * – – Annotate * – – Watch * * Can be done on own files or on files that were uploaded by others A F H B P C D Q G E B IBM Research 4
    • Factor Analysis • Review of the method of factor analysis – Start with too many variables – Find subsets of variables that are highly correlated with one another summarize each subset of variables as a factor – Continue the analysis in terms of the smaller number of factors – Figures of merit: Eigenvalue & variance-accounted-for • The 10 variables in our factor analysis On own file On file of other Upload  Download   Share   Collect   Annotate   Watch  IBM Research 5

    • Factor Analysis Results • Upload & Publicize (15935 users, 18.1%) Upload + Share-own + Collect-own – Interest in an audience for own files • Annotate & Watch (9780 users, 11.1%) Annotate-own + Annotate-other + Watch-other – Adding value / reviewing & rating – Social awareness • Discover & Tell (85303 users, 96.7%) Download-other + Share-other + Collect-other – Interest in an audience for others’ files – Personal utility of collections • Refind (5149 users, 5.8%) Refind – Download own files - Cattail as an extension of the user’s local drives IBM Research 7
    • Interpretation: How do people use file-sharing in enterprise? • Both more social and less social than anticipated – More social • Sharing, Collecting for use by others – Upload & Publicize – Discover & Tell • Similar to “Information Curators” finding (ECSCW 2009) • Apparently easy to organize (confer Rader, 2009, in public networks) – “Yours, mine, and… ours” appears to be possible in enterprise sharing – Less social • Refind – Public-access files with no viewers a sharing-failure case? • Users appropriated the technology for unanticipated purposes (Dourish, 2001; Kujala & Kauppinen, 2004) – Impression management (see also Thom-Santelli et al, 2008) – Curating (ECSCW 2009) – Refinding IBM Research 8

    • Summary of Contributions • Four factors in file sharing – In the enterprise (and beyond?) – Patterns of sociality – Patterns of individual utility – Appropriation of technology for new purposes • Implications for design – Unified user interface, supporting • Work with collections of artifacts • Impression management • Ratings by readers • Awareness of the work of others IBM Research 11
    • Who is Missing? Future Work • Analyses so far – How do people use file-sharing in the enterprise? • Four factors in usage (this note) – “Information curators” (ECSCW 2009) – Focused on people who changed the database • Upload original content • Contribute: Share (recommend), Annotate, Collect… • (also Downloaders) – Our four factors are primarily about visible contributions to the system • Lurkers in file-sharing – Lurkers are the modal users (75%) – How do lurkers use file-sharing? – What do lurkers need from a file-sharing service? – Should lurkers eventually become contributors? – Hearing the “silent” users IBM Research 12
