System Development Life Cycle
(SDLC)100% Correct!!
project - Answer is a planned undertaking, with a beginning and end that produces a
well-defined result or product.
information system development project - Answer a planned undertaking that
produces a new information system
predictive approach to the SDLC - Answer assumes that the development project
can be planned and organized and that the new information system can be
developed according to the plan
useful for building systems that are well understood and defined.
company may want to convert its old networked client/server system to a newer
Web-based system that includes a smartphone app. In this type of project, the staff
already understands the requirements very well, and no new processes need to be
added
traditional (70s-90s)
adaptive approach to the SDLC - Answer is used when the system's requirements
and/or the users' needs aren't well understood. In this situation, the project can't be
planned completely.
Some system requirements may need to be determined after preliminary
development work.
(late 90s-today)
project initiation (predictive) - Answer In predictive approaches, there is a group of
activities that identifies the problem and secures approval to develop a new system
Project planning (predictive) - Answer In predictive approaches, there is a group of
activities that identifies the problem and secures approval to develop a new system
map out the project's overall structure
analysis (predictive) - Answer focuses on discovering and understanding the details
of the problem or need. The intent here is to figure out exactly what the system must
do to support the business processes
design (predictive) - Answer focuses on configuring and structuring the new system
components. These activities use the requirements that were defined earlier to
develop the program structure and the algorithms for the new system
implementation (predictive) - Answer includes programming and testing the system.

System Development Life Cycle
(SDLC)100% Correct!!
deployment (predictive) - Answer involves installing and putting the system into
operation.
phases of the system development project (predictive) - Answer project initiation,
project planning, analysis, design, implementation, and deployment
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.
