Two years have passed since the FBI deployed Sentinel to users in July 2012.
Since the deployment, the FBI has worked to improve both the functionality and
user’s experience with Sentinel. During our audit, we found that the majority of
users who participated in our survey viewed their experience with Sentinel
positively, responding that Sentinel has increased their daily productivity, increased
their ability to share information with personnel in other offices, and enhanced the
FBI’s ability to carry out its mission. Some survey respondents also stated that
Sentinel is an improvement over ACS. However, ECTs and ELSUR Technicians
expressed concerns about the impact Sentinel had on their daily work activities that
play a vital role in the storage and management of evidence collected by the FBI.
In addition, we found that survey respondents’ satisfaction with Sentinel’s search
and indexing functionality was significantly lower than other functions because they
did not reliably receive the search results they needed and reported spending too
much of their time manually indexing information. FBI officials are aware of these
concerns and told us that they plan to address them.
The deployment of Sentinel represented significant changes in both the
technology and business processes used by FBI employees to accomplish tasks. Of
those Special Agents who responded that Sentinel had decreased their daily
productivity, a majority attributed the productivity decrease to an increase in
administrative burden. During our audit, Special Agents told us that the increase in
the administrative burden posed by indexing leaves less time for investigative
activities. Prior to the deployment of Sentinel, OSTs played a significant role in the
indexing process. Since the deployment of Sentinel, that role has been eliminated,
creating an opportunity for OSTs to potentially ease the increased administrative
burden on Special Agents in the field. However, we found that OSTs were not
always used efficiently or assigned new tasks to supplant their previous indexing duties. As a result, we believe that some user concerns, especially those relating to
indexing, may require both a technical and business process solution.
Survey respondents’ also reported that Sentinel was missing features that
they believed are critical to their duties, such as Sentinel’s integration with other
FBI IT systems and enhancements to the search capability. Enhanced search
capabilities should improve user satisfaction with Sentinel and increase the FBI’s
ability to “connect the dots.” To ensure that future enhancements are more aligned
with user’s operational needs, the FBI should consider revising how it prioritizes the
addition of new enhancements to the system. In addition, although respondents
were generally satisfied with the job-specific training and other resources the FBI
offered, Special Agents and Supervisory Special Agents reported a significantly
lower level of satisfaction with the availability of technical and policy-related
support after the deployment of Sentinel.
The total budget for Sentinel since the deployment of Sentinel 1.0 in
July 2012 has increased from $451 million to $551.4 million. This increase is the
result of operations and maintenance during FY 2013 and 2014 and the
development of new functionality during FY 2014. As of July 2014, the FBI had
obligated $529.2 million of that $551.4 million and expensed $502.1 million. The
FBI’s deployment of Sentinel 1.5, planned for October 2014, is intended to support
the needs of the FBI’s intelligence analysts by integrating legacy intelligence
systems and expanding Sentinel’s functionality by leveraging its features to support
the FBI’s intelligence mission. If Sentinel 1.5 successfully subsumes other legacy
systems or improves the integration of Sentinel with other legacy systems, the FBI
should realize cost savings from retiring systems and reducing the amount of
maintenance to operate other legacy systems.
