CACI employed Saguaro for systems analysis services for the VHA
HealtheVet VistA Imaging project. The VistA Imaging
System is an extension to the Veterans Health Information System
Technology and Architecture (VistA) that captures clinical images,
scanned documents, electrocardiogram (EKG) waveforms and other
nontextual data files, and associates them with elements of the
patient's electronic medical record. Image and text data are
provided in an integrated manner that facilitates the clinician's
task of correlating the data and making patient care decisions in a
timely and accurate manner.
Saguaro Software accomplished the following major tasks in this
engagement:
-
Developed a preliminary project plan (spanning several years) to
reengineer the VistA Imaging System.
-
Performed requirements analysis, “as-is” analysis, including
automated generation of UML models. Utilized the IBM Rational
Unified Process (RUP).
-
Served in the VHA’s Iterative Development Lifecycle (IDL)
Implementation Workgroup, in both the Project Management and
Architecture/Development task forces. The Workgroup is setting the
software development process standards and artifacts for all future
software projects at the VHA. The IDL is based on the IBM Rational
Unified Process (RUP).
-
Served in a workgroup to define a comprehensive plan to train
VHA developers in Java and Oracle technologies, and to select a
vendor to provide the training and education to the VHA enterprise
developer community.
-
Served as a voting member of the Development Technology Advisory
Committee (DTAC), established to provide technical expertise and
guidance for the VHA’s implementation of new technologies
surrounding Oracle and Java.
-
Developed software in the Java environment utilizing a
lightweight architecture without EJBs. Developed relational data
model. Participated in the design and modeling of the next
generation service-based, general-purpose imaging system.
