System life cycle
- Analysis
- 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.

- Design
- 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.

- Development and testing
- 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.

- Implementation
- 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.

- Documentation
- 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.

- Evaluation
- 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.
