Introduction
This report summarizes the activities of the Usability Engineering 2: Measurement and Methods (UE2) Symposium held March 3, 1997 at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, USA. The workshop was co-sponsored by NIST's Information Technology Laboratory (ITL) and by the Human- Computer Interaction Laboratory (HCIL) of the University of Maryland. Over 145 people attended a comprehensive technical program that included parallel tracks for managers, experts and novices.

UE2's purpose remained the same as the first symposium held in 1996: it once again brought together industry and government to exchange information and strategies for achieving effectiveness, efficiency, and satisfaction in computer-based government systems. New for 1997 was a special emphasis on measurement and methods along with a parallel track format to address the varying attendee profiles such as job function and level of expertise.

Background
The symposium continues to focus on incorporating usability engineering into the government arena and extends the work from last year's symposium (see symposium report in SIGCHI Bulletin, October 1996, pp. 66-67, Vol. 28, Num. 4). The need to incorporate UE techniques into the government arena was identified and expanded upon during several previous gatherings of human-computer interaction (HCI) professionals. Past SIGCHI Bulletin issues (October, 1994, pp. 49-50 and October, 1995, pp. 35-37) contain reports on previous gatherings.

Usability Engineering and Its Necessity In Government
The National Performance Review has the explicit objective of improving the performance of US Government agencies. We believe every government agency's peformance depends on the usability of the computerized systems that support that agency's work. Usability engineering provides practical techniques for increasing productivity and decreasing costs - two primary concerns of those procuring and building government systems. The need to specify and verify usability requirements is critical in new government systems and just as applicable in the many current and planned legacy updates. The field of usability engineering also offers ways to evaluate the mandated integration of commercial- off-the-shelf (COTS) products and evaluation of the COTS products as stand-alone tools. Procurers and builders of government systems are faced with rapidly designing and developing systems that must meet the public demand for digitized information, industry's demand for critical operation information, and workers' demands for systems that enable them to disseminate and process various information requests. It is critical that procurers and builders of government systems employ techniques that enable the development of usable governmet systems in order to maximize the return on taxpayer's dollars that fund the design and development of these systems. Economics and productivity play major roles in the exploitation of technology. As Dr. H. Rex Hartson stated in the 1996 symposium executive overview:
"We expect technology to transform the American economy into the most productive in the world. The single most significant factor in manifesting this promised productivity from the technology is USABILITY.

Demographics
The number of attendees rose 28% from last year (116 vs. 148). They included representatives from industry, government, academia, research institutes, and federally funded research and development corporations. We were especially pleased that several high-ranking government information technologists attended. One of our goals was to increase the number of decision-makers and that goal was met. All tracks were well attended including the managerial track. For comparison purposes, the attendee breakdown is listed for both the 1996 and 1997 symposiums:

Another important goal set after last year's symposium was to increase government participation especially that of non-NIST government personnel. That goal was also met as evidenced by a raw increase from 32 to 62 and an overall percentage increase from 28% of 1996 attendees to 42% of 1997 attendees. The one surprising demographic factor observed by the program committee was the decrease in industry attendance although we can attribute some of the decrease to the publicity efforts which heavily focused on attracting government personnel. Additionally, the CHI conference was early this year and several industry people informed us that they had to choose between the two meetings due to budget and time constraints.

Feedback
Similar to last year, we received much positive feedback along with suggestions for improvements and direction. Feedback was gathered via email, conversations with speakers and organizers, and symposium feedback sheets (52/148 returned). A large majority of attendees indicated the need/desire for continuation of the symposium activities. General constructive feedback and suggestions for future symposia included:
  • more time for questions and discussion
  • more case study examples
  • construction of a UE cookbook/template
  • evaluation of prototyping tools
  • evaluation and comparison of different UE methods
  • more discussion and explanation of metrics
  • attract more project managers
  • address measurement in context (quality in use)
  • evaluation of COTS
  • more practical "how to" sessions
Future Activities
The organizers are currently putting together a post-symposium publication, which is scheduled for release sometime in Fall 1997. In order to reach a wide audience and to leverage the expertise of the Usability Professional's Association (UPA), NIST and UPA plan to hold a special "government day" in conjunction with the 1998 UPA annual meeting which will be held in Washington, D.C. The government day will immediately precede the UPA conference.
