Software Development Lifecycle and its Importance

This assignment provides a comprehensive overview of the software development lifecycle (SDLC) and its significance in developing high-quality applications. It discusses the importance of SDLC, including its ability to justify excellence and correctness, and its customized approach for specific customer goals. The assignment also explores different software lifecycle models, such as V-Shaped, Iterative and Incremental, and Waterfall models, highlighting their advantages and disadvantages. By understanding these concepts, students can gain insights into the best practices for software development and improve their problem-solving skills.

Software Development
Lifecycle and its important
during development of lifecycle
The Software Development lifecycle
[SDLC] is a technique of a structured
Software development that justify
the excellency and correctness of
the developed Application. The SDLC
develops high-quality, consumer-
complaint Software.
SDLC comprised planning outlines
i.e. how complex technology should
be installed and maintained. Every
SDLC phase corporated with its next
phase within its own system and
deliverables.
Importance
[1] It is designed manually for task
and customised for customer's goals

[2] Helpful in assessment, planning
and in determining expectations
[3]It is structurally standard
arrangement of exercises
[4] It assures the right and easy
conveyance to the customer
Different Software Lifecycle and
Software Lifecycle Models
There are two types of Software
Lifecycle; V-Shaped and Iterative and
Incremental
V-shaped Model
It designates as waterfall where
water is moving down step by step
rather than moving down in a
straight path, bent it upwards after
designation and encoding stage.
However early test scheduling made
it difference from waterfall model.

Advantages
[1]Speedy and social
[2] Each step designated for specific
output
[3]Due to its own test planning
designation, it has a lower chance of
success over waterfall model
[4] Made it easy so that it can
function well in understanding some
specifications
Disadvantages
[1]Stiff in designation
[2] Due to it high cost prototype of
this Software can't develop
[3] During teat conduction process,
the design couldn't provide a clear
path for problems fixing
[4] It is a time consuming and costly

Iterative and Incremental Model
In contrary to V-shaped Model, it is
an advance in model. Its beginning
has an initial planning and interacted
with cycle interation during its
productions during its production. It
is implemanted through repeated
cycles and made it as latest model
through vary cycles process within
its development stages.
Advantages
[1]Added business value
[2] Made it easy-going with a little
resources
[3] Needs a small demands for
improvement
[4]Give importance to consumer
value rather than linear
approachable

[5] Having upgraded system for
fixing problems
Disadvantages
[1] wasting a lot of paperwork
[2] Follow a series of commands that
are installed
[3]For proper functionality ,required
time intervals
[4] Made consumer busier
[5]problamatic to some functional
partitions and features
[6] There may arise problems among
its integrations
Sequential Software Models
types[1] Waterfall Model [2]
Evolutionary-Prototyping Model
Waterfall Model

It is designated as straight flow of
water from its peak . There is a slow
downward flow the code;the code
implementation phase.This means
that there will be no upwards flowing
again, once the water flow down in
waterfall model. The approach to
waterfall doesn't integrated the
process of going back
Advantages
[1] Easy to explain
[2] Structurally approaches
[3] Well defined phases and
activities
[4] Approachable in planning and
scheduling
[5] Fix problems at early stages and
verified it
[6] Each stages has some specific
