A Change to Open Systems Improves Communication for a Statewide Court
Administration System
Utah Administrative Office of Courts Case Study
"Increased response time has drastically reduced the amount of time it
takes to process court cases, while the change to an open systems
environment has created the potential for future expansion of the courts
administrative system."
The Utah Administrative Office of Courts services all the adult courts
in the State of Utah. With a growing population of over 2 million
residents, the existing system of minicomputers and workstations was
unable to accommodate the increased demands placed upon it. More
efficient data communication between the individual courts was desired,
as well as greater access to the court by public and other government
agencies. By 1990, it became apparent that significant computer
enhancements were required. The change to an open system was also begun
at this time to enable the eventual implementation of a statewide
client/server environment.
Hewlett-Packard designed a system that will eventually connect 44
regionally-located PC LANs to 14 regional UNIX(R) data servers. The new
system has already reduced total maintenance by 50%. Increased response
time has drastically reduced the amount of time it takes to process
court cases, while the change to an open systems environment has created
the potential for future expansion of the courts administrative system.
Background
The Utah Administrative Office of Courts (AOC) services all of the adult
courts in the State of Utah. Prior to 1985 there were no automated
systems in use. The courts relied on contracted services from nearby
city or county offices. In 1985, an aggressive plan to automate the
court system was put into effect. The result was a statewide system for
collecting basic caseload statistics consisting of 44 minicomputers (one
per court) linked by an X.25 network. Each minicomputer was connected to
a number of workstations, ranging from 4 to 150.
Time for a change
The system was intended to provide greater public access to the courts,
and interface electronically with the computer systems of several
government entities. These included:
o Statewide Warrant System
o Drivers License Reporting
o Traffic
o Criminal History Reporting
o Salt Lake City Parking/Small Claims System
With a growing population of over 2 million residents, AOC's existing
system was unable to accommodate the increased demands placed upon it.
Although the minicomputers were linked, the procedures for obtaining
data from remote sites were so complicated that only a few highly
trained specialists could carry them out. As a result, gathering data
was an inefficient process, and a simple request for information could
take days to complete. Often, the information collected about case flow
and composition was not readily available when significant decisions
needed to be made. It was as if each court kept a separate system of
information, not connected in any way to the others.
In addition, there were continuing problems with unacceptable down
time, difficulty in obtaining replacement parts, high software costs,
and poor performance in general.
More efficient data communication between the individual courts was
desired, as well as greater access to the court by public as well as
other government and private organizations. The cost to upgrade and meet
the growing demand using the existing strategy of proprietary systems
became unacceptable, and by 1990 it was apparent that significant
computer enhancements were required. The decision was made to replace
the existing eight hundred workstations with PCs, and to migrate to a
UNIX-based open system. This would eventually allow implementation of a
statewide client/server environment.
Choosing an open systems partner
To begin the process of change, an independent survey of the courts was
commissioned. Focus groups made up of members of the community, media,
and private industry were formed to express their needs and concerns for
more information from the court systems. Based on this input, the
Judicial Council put together a Data Processing Master Plan with
recommendations for AOC's future information technology investments. The
Council presented this to the Standing Committee on Information,
Automation and Records. The following criteria for a viable solution
were developed:
o ability to operate in a distributed, statewide environment
o client/server architecture with UNIX data servers
o ability to reduce data processing costs and staffing requirements
o price/performance
o noise level (PCs only)
The unusual requirement for quiet operation was important because
many of the PCs would be used in courtroom situations.
AOC carefully reviewed competitive bids from various hardware
suppliers. Three separate requests for bid were issued, one each for:
o networking, consulting, and hardware
o UNIX data servers
o PCs.
Hewlett-Packard won all three bids. In the networking area, HP's
selection was due to its strong service capabilities and ability to
provide all the necessary hubs, routers, and bridges. Price was key in
the UNIX server bid, where HP was able to offer the best
price/performance on the market. The HP Vectra PCs were the quietest
contenders, and were competitively priced. HP's solid experience in open
systems played an overall role in the decision, as did HP's stability
and reputation for quality.
Making the change to a client/server environment
In addition to providing hardware, Hewlett-Packard worked with AOC in a
consulting capacity to design a client/server system that will
eventually connect 44 sites to 14 regional UNIX-based servers containing
court information in an Informix relational database. The clients are HP
Vectra PCs running DOS/Windows-based applications. They operate in
Novell Netware local area networks (LANs) varying in size from 5 to 200
PCs. The LANs are linked to HP 9000 UNIX data servers via an EtherNet
network comprised of HP hubs, routers and bridges.
Supporting future expansion
Today the Utah Administrative Office of Courts is able to easily share
information with the public, as well as other government and private
organizations. There are currently over 750 users, along with 10 outside
agencies and departments.
The new system is still in the process of deployment, but it has
already reduced total maintenance by 50%, while improving productivity
by significantly reducing computer response time. The response time
improvement alone will drastically reduce the amount of time it takes to
process court cases.
The change to an open systems environment has created new
opportunities to use other technologies in the future such as touch
screen, imaging, multimedia, and EDI. The successful migration to
Hewlett-Packard hardware and software will support future demands upon,
and the expansion of, the AOC system.
