The

(
SDLC

,
or
Software
development
process
in
systems
engineering
,
information
systems
and
software
engineering
,
is
a
process
of
creating
or
altering
information
systems
,
and
the
models
and
methodologies
that
people
use
to
develop
these
systems
.
In
software
engineering
,
the
SDLC
concept
underpins
many
kinds
of
software
development
methodologies
.
These
methodologies
form
the
framework
for
planning
and
controlling
the
creation
of
an
information
system
:
the
software
development
process
.

.
Computer
systems
are
complex
and
often
(
especially
with
the
recent
rise
of
service
-
oriented
architecture
)
link
multiple
traditional
systems
potentially
supplied
by
different
software
vendors
.
To
manage
this
level
of
complexity
,
a
number
of
SDLC
models
or
methodologies
have
been
created
,
such
as

A
Systems
Development
Life
Cycle
(
SDLC
)
adheres
to
important
phases
that
are
____________________
for
developers
,
such
as
planning
,
analysis
,
design
,
and
____________________
.

.
?
Preliminary
Analysis
:
The
objective
of
phase
1
is
to
conduct
a
preliminary
analysis
,
____________________
alternative
solutions
,
describe
costs
and
benefits
and
submit
a
preliminary
plan
with
recommendations
.
5
.
?
Systems
analysis
,
requirements
definition
:
Defines
project
goals
into
defined
functions
and
operation
of
the
intended
application
.
Analyzes
end
-
user
information
____________________
.
6
.
?
Systems
design
:
Describes
desired
features
and
operations
in
detail
,
including
screen
layouts
,
business
rules
,
process
diagrams
,
____________________
and
other
documentation
.

.
?
Development
:
The
real
code
is
written
here
.
8
.
?
Integration
and
testing
:
Brings
all
the
pieces
together
into
a
special
testing
environment
,
then
checks
for
____________________
,
bugs
and
interoperability
.
9
.
?
Acceptance
,
installation
,
deployment
:
The
final
stage
of
initial
development
,
where
the
software
is
put
into
____________________
and
runs
actual
business
.
10
.
?
Maintenance
:
What
happens
during
the
rest
of
the
software's
life
:
changes
,
____________________
,
additions
,
moves
to
a
different
computing
platform
and
more
.
This
is
often
the
longest
of
the
stages
.
