I N IU in a nutshell D I A N A U N I V E R S I T Y • • • • • • Founded in 1820 $2B Annual Budget 8 campuses >90,000 students 3,900 faculty 878 degree programs; >1,000 majors; > 60 programs ranked within top 20 of their type nationally • University highly regarded as research and teaching institution I N D IT@IU in a nutshell I A N A U N I V E R S I T Y • Academic programs in IT through computer science, library and information sciences, engineering and technology, and most notably through new School of Informatics • CIO: Vice President Michael A. McRobbie • ~$70M annual budget • Technology services offered university-wide • UITS comprises ~500 FTE staff, organized into crosscutting units (e.g. finance and HR) and four technology divisions (Teaching & Learning Information Technology,Telecommunications, University Information Systems, Research and Academic Computing) I N D I A N A U Transformations N I V E R S I T Y A Bit of Anthropology of Organizations and How IT Is Organized I N D Culture, Strategy, Organization & Structure I A N A U • Mary Douglas.

The Balanced Scorecard. HBS Press, Boston, MA, 1996. • Four dimensions of retrospective and prospective measures – Financial perspective: deployment (and growth) of revenue, ABC against internal (historical) and external benchmarks – Customer perspective: customer satisfaction measures, number of partnerships with faculty in teaching and research, support of university business processes, support of library processes – Internal perspective: process measures, classic IT measures of availability, cost-of-poor-quality, speed and depth of development cycles – Learning perspective: employee satisfaction, employee development (MSCE, CCNE, etc.), personal alignment of employee goals with position I N D I A N A U Measuring Quality and Cost N I V E R S I T Y Customer Surveys Activity Based Costing I N D Importance of Quality I A N A U N I V E R S I T Y • Claiming that quality is important is easy. Doing something useful is hard. • Measurement of quality requires – Leadership initiative – Understanding your services – Commitment to two-way, fact based communication with customers • Motivations at IU – Initiative – Feeling of responsibility – Responsibility center management I N D RCM I A N A U N I V E R S I T Y • RCM Implemented at IU in 1989 (Whalen 1991). • IT organization(s) defined as a Responsibility Center; paid for through a non-discretionary tax on other RCs • IT customers are also captive users • Why not decentralize? I N D User Satisfaction Survey I A N A U N I V E R S I T Y • Created out of leadership desire for quality and accountability, and desire for fact-based response to assaults on IT center’s budget • Key features of Survey – Administered by independent survey organization – Stratified random sampling; survey center finalizes and administers survey, performs randomization, tabulates responses, ensures anonymity – This assures credibility and quality of data – Longitudinal comparisons assured by consistency of questions from year to year I N D User Satisfaction Survey details I A N A U N I V E R S I T Y • Undergraduate students, graduate students, staff, and faculty sampled. N has varied; current 1000 undergrad, 500 each remaining category per campus • Likert scale, Y/N questions, demographic information, opportunity for comments at end • Data reported as average score (+ 95%CI), satisfaction percentage (percent scoring 3-5), percentage who use a service. • All results, including every text comment ever written [identifying references deleted] available on the Web at http://www.indiana.edu/~uitssur I N Some key results: Overall Satisfaction D I A A U N I V E R S I T Y Percentage N 99 97 95 93 91 89 87 91 92 93 94 95 96 Year 97 98 99 00 I N D I Overall quality maintained by attention to individual services A Satisfaction with Stat/Math Center N A N I V E R S I T Y Percentage U 100 90 80 70 60 93 94 95 96 97 Year 98 99 00 I N User demographics: ownership D I A A U N I V E R S I T Y Percentage N 100 90 80 70 60 50 40 91 92 93 94 95 96 Year 97 98 99 00 I User demographics: time spent using computer per week N D I A A U N I V E R S I T Y Hours per Week N 20 18 16 14 12 10 91 92 93 94 95 96 Year 97 98 99 00 I N D Survey Credibility and Utility, 1 I A N A U N I V E R S I T Y • Response rates: – IUB survey response rates in 1991 ranged from 23% (undergraduates) to 50% (faculty). – IUB response rates in 2000 ranged from 41% (undergraduates) to 71% (staff) – IUPUI survey initiated in 1997 with a 26% response rate for undergraduates – IUPUI response rate for 2000 at 36% (undergraduates) to 48% (staff) • High response rate due to small incentive ($5-$10 value) and to recognition of value of survey I N D Survey Credibility and Utility I A N A U N I V E R S I T Y • External – Results disseminated rapidly and widely. Survey conducted Feb-end of April; results on Web in July or August – Results, and actions taken as a result, publicized widely throughout the year • Internal – Key component of annual internal quality assessment/plan – Often used in internal proposals as justification I N D I A N A U N I V E R S I T Y Survey Credibility and Utility: VAX phaseout as an example • IU had largest academic VAX center in US, and had depended upon VAXes for ~15 years • IT organization announced plan to eliminate use of VAXes within 3 years in 1994 • Cost and quality measures informed this decision • Reaction: horror, humor, horror I N D VAX phaseout reaction I A N A U N I V E R S I T Y • Horror: initial reaction of user community. Project leader set the following goal: Within two years, at least 95% of those surveyed would respond “yes” to the question “Is the improvement in your computing environment sufficient to more than outweigh the cost to you of conversion” • Humor: initial reaction of some colleagues • Horror: reaction of project team when they realized the project manager was serious I N D VAX phaseout: the results I A N A U N I V E R S I T Y • The goal was met. • The setting of user satisfaction (rather than computer center convenience) as a key goal resulted in openness to the project that was essential to its success • Full details on Web: Stewart, C.A., et al. 1998.

I A N A U N I V E R S I T Y The KB is a system with three physical components: 1. It is a repository of problems and their resolutions (currently holding over 7,000 entries); 2. It is a search engine to sort through that repository (currently handling over 50,000 queries each week); and 3. It is a user interface that allows a user to engage the search engine to manage the data in the currently used by hundreds of thousands of users worldwide).

As most of you have hopefully heard by now, the Active Directory is an upgrade to the universities current Windows NT 4 infrastructure. UITS is planning on a production deployment by late February. Please join us in an information session this coming Friday morning, February 2nd 9:00 am in BS 2007. We will be discussing the design and architecture of the new Active Directory as well as some new technologies that will be introduced in this upgrade. Representatives from LSP Services, Messaging and the Security office will be there. This will be followed up by a question and answer session. If you have any questions please don't hesitate to bring them with you and ask!
