• Information Management Requirements
  Development Process
• IMTR contributes to the DOD Military Health
  System (MHS) information architecture by
  implementing the vision to provide a central link
  between business and clinical processes and
  activities through enterprise-wide business rules
  and a single common information repository for
  all DoD patients, providers, and managers. IMTR
  standardizes products and services to achieve
  cost reductions, performance gains, and resource
  optimization. CTA manages the functional and
  technical requirements within the MHS core
  business processes. This includes the collection,
  refinement, and integration of functional issues
  and how they relate to the operational
  architecture and its data dictionaries. The
  result is a requirements repository that
  coordinates the functional aspects of an
  application to the data and data structures
  within the system which provide a usable decision
  making mechanism to help direct the organization
  to achieve its objectives.
• IMTR is made up of two organizations
  Information Management (IM) and Information
  Technology (IT). CTA has been responsible for
  the modification and implementation of the IM
  Requirements Development Process (RDP), to
  include the development and delivery of a
  comprehensive training program.
• The Information Management Requirements
  Development Process provides consistent,
  repeatable processes for the IM staff to utilize
  while eliciting, and developing AIS functional
  requirements. The use of a standardized process
  for user requirements is necessary to achieve
  level 3 of the Software Engineering Institutes
  Software Acquisition Capability Maturity Model.
  CTA has developed and documented step by step
  procedures for the information managers and
  analysts to use while working through the five
  phases of the RDP which assists them to follow a
  standard process from beginning to end.

• CTA utilizes the Dynamic Object Oriented
  Requirements System (DOORS) as the MHS repository
  tool of choice. The CTA employees are expert
  administrators and users of this database, which
  allows for real-time updates and transparent
  maintenance. We are expanding use of the DOORS
  Change Proposal System to allow the information
  management analysts to more easily update their
  requirement data.
• Throughout the RDP performance measurement and
  configuration management occurs. Metrics have
  been established to monitor Submissions
  Processing, Status Feedback, and overall Process
  Quality. Status codes which correspond to each
  step of the RDP are used to track submissions and
  measure the time required along the way. Metrics
  by business process area and current status allow
  the information managers to monitor the progress
  of a submission and conduct workforce planning.
• Requirements (Functional, Technical, System and
  Design) and associated documentation are
  baselined and maintained under formal change
  control throughout the system development life
  cycle. Traceability from user elicited
  requirements through formal acceptance test is
  fully maintained. The DOORS repository allows
  links from the initial submission, to the
  portfolio management, and then to the functional
  requirement module. Once baselined, these
  requirements are transitioned and linked to the
  corresponding IT solution, and test data.
• Training of the RDP is conducted by CTA personnel
  as required by IMTR. A training plan, syllabus,
  training course materials, and training program
  management software have been developed and
  utilized to manage the Program. This training
  consists of seven lessons which cover all phases
  of the RDP, to include requirements elicitation
  and development, user scenarios, business process
  models, concepts of operations, portfolio
  management and the budget process, and
  operational architecture.
• The RDP and its implementation are undergoing
  Continuous Process Improvement. Revisions are
  published every six months. Training is updated
  accordingly, and redeveloped to ensure
  organizational awareness and understanding.

Agent Engineering
Computer Technologies Associates, Inc.

• Computer Technology Associates (CTA) is helping
  DoD, the intelligence community and homeland
  defense organizations develop advanced
  network-centric sensor systems that will enhance
  situational awareness via the integration/fusion
  of sensor data from diverse "stove-pipe"
  platforms. These systems require underlying
  software architectures and cognitive support
  tools which are being designed by CTA to deal
  with the large volumes of data in near real time
  and adapt to dynamically changing network
  topologies and data fusion technologies.CTAs
  RD initiatives are directed at the application
  of intelligent software agents, relatively mature
  in the commercial sector, to these architectural
  challenges. Agents can be defined as a software
  program with the following three attributes
• It performs a specific task on behalf of a user
• It possesses a degree of intelligence that
  permits it to perform parts of its tasks
  autonomously (provided by an algorithm)
• It interacts with its environment (the program
  obtains its inputs in an unconventional manner,
  i.e., from its environment rather than from a
  tape, data file, or keyboard)

In support of this initiative, CTA has
established an agent engineering practice
(www.agentengineering.com) directed at the test
and evaluation of advanced sensor exploitation
algorithms and intelligent agent technologies as
applied to the automation of military sensor
exploitation/targeting operations. In addition,
the agent engineering practice is directed as RD
in the applications of advanced agent technology
in large-scale sensor networks, space-based
constellation systems automation, and information
security.CTA is currently applying its
technology to time-critical targeting
applications such as the National Imagery Map
Agency (NIMA) sponsored "Global Strike Force
Network-Centric Surveillance and Targeting"
(GNCST) initiative and related tactical
reachback" programs. Agent engineers are
collaborating with healthcare subject matter
experts to transfer the knowledge and application
to clinical and healthcare domains.
