Stages of the SDLC - correct answer ✔✔Planning
Analysis
Design
Implementation
Maintenance
Planning Phase of SDLC - correct answer ✔✔Total information system needs are identified,
prioritized and arranged.
Analysis Phase of SDLC - correct answer ✔✔Requirements are gathered from users. The
requirements are then studied and organized. Finally, all redundancies are eliminated.
Design Phase of SDLC - correct answer ✔✔Analysis requirement is converted into logical and
then physical system specifications
Maintenance Phase of SDLC - correct answer ✔✔The system is systematically repaired and
improved
Why is the planning phase important? - correct answer ✔✔You need to know what your needs
are. A solid plan on how to move forward helps.
Why is the Analysis phase Important? - correct answer ✔✔To understand what users seek from
the system. You need to know what's needed to be successful
, Why is the Design phase important? - correct answer ✔✔Allows us to make the ideas a tangible
thing. Without this phase we would have no idea how to implement the system.
Why is the implementation phase important? - correct answer ✔✔We need to build the system
itself
Why is the maintenance phase important? - correct answer ✔✔Bottlenecks or possible
improvements may be apparent. In that case, maintenance allows us to go back and correct
certain areas.
Does one person perform all the steps of the SDLC or is it possible that the work may be split
across a number of role players in systems development? Who might be the key role players and
what role would each play? - correct answer ✔✔Generally speaking one person is not in charge
of all steps, rather it is delegated around. Planning, for instance, can be done by end users or
support personnel.. In the analysis stage an analyst would most likely be the one governing this
phase going over what needs to be done to be successful. In the Design stage you may have
your engineers or computer scientists working on ways to make this thing happen. In the
implementation phase you may once again have the engineers or computer scientists creating
the system itself. Maintenance stage can be done by anyone... Problems arise and are fixed.
What are some criticisms of the traditional SDLC? - correct answer ✔✔Feedback is often
ignored, resulting in early errors or omissions being carried into later stages where they would
be harder to identify and correct
Requires significant amount of process and documentation. Many organizations end up having a
large overhead of staff whose sole purpose is to create and maintain the documentation for the
SDLC
What are the advantages of the SDLC? - correct answer ✔✔SDLC on the allows for a very
structured way to create a new system.
SDLC when implemented correctly can be greatly beneficial at improving systems.
