Information Management Requirements Development Process
IMT&R 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. IMT&R 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.
IMT&R 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 Institute’s 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 realtime 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
IMT&R. 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.
