WGU C790 Nursing Informatics OA Exam A, B & C
SLC Stages .......Answer.........Feasibility and analysis, planning,
develop or purchase, implementation, maintenance and
evaluation
1) Feasibility and analysis (SLC) .......Answer.........The existing
environment and systems are evaluated. A readiness assessment
may be conducted. User needs and information system
deficiencies are identified using informal or formal methods.
New system requirements are defined. Deficiencies in the
existing system are addressed with specific proposals for
improvement.
2) Planning (SLC) .......Answer.........The proposed system is
planned and designed. Planning includes extensive work in
myriad topics: physical construction, hardware, operating

systems, programming, communications, implementation support,
evaluation, and security issues. A workflow analysis and process
reengineering may be completed as a basis for determining the
scope of system functions and the flow of information and
activities within care processes.
3) Develop or Purchase (SLC) .......Answer.........The new system is
developed or purchased. New components and programs are
obtained and installed. For vendor-supported solutions,
extensive tailoring occurs. Users are trained in its use and all
aspects are tested. Ideally, adjustments are made at this stage
to correct gaps in the scope of system functions or work
processes.
4) Implementation (SLC) .......Answer.........The new system is
developed or purchased. New components and programs are
obtained and installed. For vendor-supported solutions,

aspects are tested. Ideally, adjustments are made at this stage
to correct gaps in the scope of system functions or work
processes.
5) Maintenance and Evaluation .......Answer.........Once the new
system is up and running, it should be evaluated exhaustively. A
maintenance phase begins to focus on maintaining system
integrity, upgrades, and correcting issues that arise. Evaluation
occurs at the end of the cycle.
Staggers and Nelson Systems Life Cycle Model (SLCM)
.......Answer.........depicts the cycle as a spiral. incorporates
revious work from Thompson, Synder-Halpern, and Staggers.
Steps: Analyze, Plan, Develop or Purchase, Test, Implement or
Go-Live, Maintain and Evolve, Evaluate, Return to Analyze

what is occurring and how one understands the intervention to
solve a problem is called
Chaos Theory, Systems Theory .......Answer.........two major
theories that help us analyze and explain the occurrences or
instances of certain phenomena with health informatics
goal of EBP .......Answer.........is improvement of systems and
microsystems within healthcare, with these improvements based
on science
STEEEP principles .......Answer.........The Institute of Medicine (IOM)
expert panel issued recommendations for urgent action to
redesign healthcare so that it is safe, timely, effective, efficient,
equitable, and patient-centered
