System life cycle
Analysis
Design
Development and
testing
Implementation
Documentation
Evaluation
The end-user’s requirements should be determined and
documented, what their expectations are for the system,
and how it will perform. A feasibility study will be made
for the project as well, involving determining whether
it’s organizationally, economically, socially,
technologically feasible. it’s very important to maintain
strong communication level with the clients to make
sure you have a clear vision of the finished product and
its function.
The design phase comes after a good understanding of
customer’s requirements, this phase defines the elements
of a system, the components, the security level, modules,
architecture and the different interfaces and type of data
that goes through the system.
This phase produces the software under
development. Depending on the methodology, this
phase may be conducted in time-boxed “sprints,”
(Agile) or may proceed as a single block of effort
(Waterfall.) Regardless of methodology,
development teams should produce working
software as quickly as possible.
-Code quality, Unit testing
(functional tests), integration
testing, performance testing,
security testing.
Is the post-implementation review. This
phase identifies whether the system
meets the initial requirements and
objectives. This is when the system is
evaluated for weaknesses. The objective of
the evaluation phase of the systems
development life cycle is to deploy the
system and train the system end users.
The user documentation is
intended to help the users of
the system. The users are
usually non-technical people, who
don't need to know how the
system works. They just need
to know how to use it.
The new system is
introduced in phases
(stages, or steps),
gradually replacing parts
of the old system until
eventually, the new
system has taken over.
