Project - CORRECT ANSWER✔✔✔is a planned undertaking, with a beginning and end that produces
a well-defined result or product.
information system development project - CORRECT ANSWER✔✔✔a planned undertaking that
produces a new information system
predictive approach to the SDLC - CORRECT 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 - CORRECT 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) - CORRECT 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) - CORRECT 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) - CORRECT 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) - CORRECT 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) - CORRECT ANSWER✔✔✔includes programming and testing the system.
deployment (predictive) - CORRECT ANSWER✔✔✔involves installing and putting the system into
operation.
phases of the system development project (predictive) - CORRECT ANSWER✔✔✔project initiation,
project planning, analysis, design, implementation, and deployment
support phase (predictive) - CORRECT 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) - CORRECT 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) - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER✔✔✔provides guidelines for every facet of
the system development life cycle.
model - CORRECT ANSWER✔✔✔representation of an important aspect of the real world
