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
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
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.
|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.

|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:|
|1996 - 116 attendees||1997 - 148 attendees||relative difference|
19 (16%) NIST
32 (28%) non-NIST gov.
31 (21%) NIST
62 (42%) non-NIST gov.
|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.|
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:
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
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.
We invite and welcome participation in our activities. Anyone interested in focusing on usability in the government arena may send email to email@example.com (+1-512-425-5495) or firstname.lastname@example.org (+1-301-975-4535) for more information.
Laura L. Downey, chair of the symposium, is a computer scientist at Vignette Corporation. Laura's research focus is
on human-computer interaction with a special emphasis on usability engineering.
Currently she is conducting a system evaluation of an information retrieval
(IR) prototype, and investigating rapid, remote, and automatic methods for
evaluating web site usability.
Dr. Sharon J. Laskowski is a computer scientist and group leader of the Visualization and Virtual Reality Group in the Information Technology Laboratory of the National Institute of Standards and Technology where she is currently investigating the application of visualization techniques to information retrieval and navigation. She has also participated in research and prototyping efforts focusing on usability and searching of World Wide Web-based virtual libraries. Previously, she conducted research and development in text analysis, information fusion, and plan recognition at the Artificial Intelligence Center of the MITRE Corporation. Dr. Laskowski received her PhD in computer science from Yale University.
