WGU C790 NURSING INFORMATICS STUDY
GUIDE 2026 PRACTICE QUESTION SET ONE
◉ support phase (predictive). Answer: includes the activities needed
to upgrade and maintain the system after it has been deployed. The
support phase is part of the overall SDLC, but it isn't normally
considered part of the initial development project
◉ waterfall model (predictive). Answer: the phases of the project
flow down, one after another.
This model assumes that the phases can be carried out and
completed sequentially.
After a project drops over the waterfall into the next phase, there is
no going back
rigid planning, doesn't work very well
◉ interative approach (adaptive). Answer: Using iterations, the
project is able to adapt to any changes as it proceeds. Also, parts of
the system are available early on for user evaluation and feedback,
which helps ensure that the application will meet the needs of the
users.
,overlapping phases
is adaptive because with each iteration's analysis, design, and
implementation, modifications can be made to adapt to the changing
requirements of the project
◉ incremental development. Answer: related concept to interative
SDLC
based on an iterative life cycle
basic idea is that the system is built in small increments
may be developed within a single iteration or it may require two or
three iterations. As each increment is completed, it is integrated
with the whole
"grown" in an organic fashion
gets into user's hands faster
◉ walking skeleton. Answer: based on interative approach
,provides a complete front-to-back implementation of the new
system but with only the "bare bones" of functionality.
gets into user's hands quickly
◉ system development methodology. Answer: provides guidelines
for every facet of the system development life cycle.
◉ model. Answer: representation of an important aspect of the real
world
◉ abstraction. Answer: people abstract (separate out) an aspect that
is of particular importance to them.
◉ tool. Answer: software support that helps create models or other
components required in the project.
◉ integrated development environments (IDEs). Answer: sets of
tools that work together to provide a comprehensive development
and programming environment for software developers
◉ visual modeling tools. Answer: tools that help analysts create and
verify graphical models and may also generate program code
, ◉ technique. Answer: a collection of guidelines that specify a
method for how to carry out a development activity or task
Sometimes, a technique applies to an entire life cycle phase and
helps you create several models and other documents.
◉ How do methodologies, models, tools, and techniques fit
together?. Answer: A methodology includes a collection of
techniques that are used to complete activities within each phase or
iteration of the system development life cycle. The activities include
the completion of a variety of models as well as other documents
and deliverables. Like any other professionals, system developers
use software tools to help them complete their activities
◉ Agile development. Answer: a guiding philosophy and set of
guidelines for developing information systems in an unknown,
rapidly changing environment
compliments adaptive approaches
◉ Agile modeling. Answer: a philosophy about how to build models,
some of which are formal and detailed, others sketchy and minimal
