A LOW COST APPROACH TO HIGH TECHNOLOGY
By
Mark Clark
Lieutenant
South Portland, Maine, Police Department
How does a department move out of the time-honored carbon
copy world into the computer age? Obviously, this is not an
easy question to answer, because the process itself can be a
monumental undertaking. Yet, it can be done, as many police
departments across the country have proven. This article
details the steps taken by the South Portland, Maine, Police
Department to enter into the world of computerization.
When the chief of police in South Portland decided to
expedite the department's recordkeeping process with automation,
he stipulated certain conditions. First, the task at hand was to
simplify department records without deleting any part. Second,
only $25,000 could be used from the department's budget, and
third, the transition would be handled by an officer. That was
my assignment--to acquire and maintain the new computer system.
My first step was to talk to the neighboring police
department in the Town of Scarborough, since its police
department was also interested in automating its record system.
Since they also had funds available, the officer assigned to
coordinate the Scarborough computerization effort and I arranged
to acquire jointly a computer system for both police departments.
This provided an immediate advantage because we could purchase a
computer system at a substantial discount since we were buying in
larger quantity.
This joint venture later developed into a broad cooperative
effort between the City of South Portland, the Town of
Scarborough, and the Sanford Police Department. It also created
a criminal justice information network that has grown into a
statewide standard.
CHOOSING THE RIGHT HARDWARE AND SOFTWARE
Computer Hardware
We concentrated first on hardware needs, primarily because
most computer downtime is caused by hardware problems, not by
software. Ease of installation and low maintenance costs, as
well as readily accessible and long-term hardware support, were
our other major concerns.
Because we did not know what our needs were at first, we
contacted all the major vendors by means of a reverse bid.
These vendors then submitted non-binding hardware proposals of
what they believed we needed. These proposals allowed both
departments to compare and justify speed (processing)
requirements, RAM requirements, main memory storage, and
provided an excellent springboard for us to write our actual
bid. This also made it easier to see how much money would be
left to purchase software.
After the vendors placed their bids, we met with
representatives from each vendor to let them explain why their
system was better and what they could do for each department.
This was an eye-opening experience, because often what the
vendor's literature boasted at bid time was not always exactly
what the purchaser actually received. It also allowed us to
make educated, progressive decisions toward accurately assessing
any longer term needs.
After considering all the options, we decided to purchase a
mini-mainframe. This would allow for easier expansion with
minimal cost. Also, with a mini-mainframe, a computer terminal
can be added for one-half the cost of purchasing a separate
personal computer.
Computer Software
The world of computer software is inundated with buzzers,
bells, and flashing colors. At this point, all the major
software vendors put on excellent presentations of their
packages. Yet, even though these software packages were
everything in the world a user could want, they were also
accompanied by a price tag ranging from $8,000 to $20,000.
Packaged systems contain a number of good features, but they
also have features that are not wanted or needed. For example,
most criminal justice software packages come with a standard
computer-aided dispatch system. Yet, for our department, this
feature was unnecessary, and therefore, not wanted.
Since the vendors could not supply an applicable software
package within our price range, we decided to contact another
police department in Maine that had developed its own software
using the Relational Database Management approach. This
software, written on the Informix SQL RDBMS system, covers topics
such as complaints, accidents, property/case control, and uniform
crime reporting. It is also very flexible and allows systems
administrators to customize each program to meet the individual
needs of their departments. But, the most important factor to
consider was that it was offered to us free of charge. This
system provided everything we needed and also allowed us to
remain well within budget. Now came the hardest part of the
whole process--the task of implementing the automated system.
IMPLEMENTING THE SYSTEM
Without proper planning, implementing a computer system can
be very stressful. It is usually simple to install the hardware
and to run the wiring, but this is far from the operational
stage. With technical assistance from hardware and software
vendors, it is usually fairly painless. But, because we did not
purchase a software package from a vendor, there was no followup
support. Therefore, we had to deal with the following items
without benefit of software "experts":
* Software installation
* System administration
* Customization
* Documentation and
* Training
Software Installation
Installing software is usually fairly simple. The installer
simply has to follow the directions and load the system one disk
at a time. In our case, the hardware vendor who set up the
equipment was very helpful at this point because the operating
system was part of their original bid.
System Administration
System administration is a major concern, because it is at
this point that the in-house systems administrator takes on the
day-to-day role of problem solver. If the computer system does
not work, this person had better know how to solve the problem or
at least have a telephone number of someone who can. However, it
does not take someone with a computer background to solve most
problems. In this case, with three departments on the same
system, systems administrators could use each other as resources
or consultants. This is important because in most police
departments, the officer who is the systems administrator, as I
am, usually has other duties to perform and may not have time to
become completely familiar with how the system operates.
Customization
Customization is the process of taking a generic computer
program and tailoring it to a department's exact needs. This is
one advantage of the Informix SQL RDBMS system over a purchased
software package. Because the programs were customized to
duplicate currently used forms
