Additional reports such as the AFIS production summary report and the AFIS
quality control production summary report round out the information avail-
able from the AFIS system.

5.5.2 LATENT PRINT REPORTS

The first question typically asked of the latent print abilities of an AFIS system
is how many idents were made. After all, the purpose of an Automated Fin-
gerprint Identification System is to support identifications. How many idents is
a legitimate question. But is it the right question?
What about other questions, such as how many idents cleared cases, how
many idents resulted from latent print to tenprint searches, and how many
idents resulted from tenprint to unsolved latent print searches? While these are
all identifications, they result from different search techniques and different
processing. The development of latent print reports may require the capture
of a search reason field on latent print searches. This is crucial in order for
reports to have any merit. Without the search reason delimiter, automated
reports could include ident information from tests and demonstrations
mingled with results from normal latent searches.
Each report on the latent print system that is case related must include the
search reason as a parameter. For example, reports that indicate the number
of LT/TP searches launched or verified in a particular time period are pre-
sumed to include only those cases in which the search reason is a latent entry
search. These reports must be able to provide information on any one of three
levels: operator, site (each operator and site summary), or system (site summary,
system summary), and they must be robust enough to capture information over
time periods varying from days to years. Each report has options for reporting
period, operator(s)/site(s), and field(s). Design criteria should include options
for reports to be displayed at any terminal, produced on paper, or saved in
ASCII or, increasingly, html format. In addition to the designed reports, there
are provisions for ad hoc repots to be produced. The vendor has to provide
training in the mechanics of producing these ad hoc reports.
Latent print reports are presented to three primary, but not mutually exclu-
sive, audiences: first line supervisors, whose primary interests are throughput
related; system administrators, whose interests are related to the effectiveness
of the system, e.g., case closure; and a system improvement audience, whose
goal is to enhance the efficiency of the system through improved identifica-
tions, higher throughput, and better practices.
The following four reports are examples of reports that should be available
on a scheduled or ad hoc basis:
