Software life development cycle

The sequence of stages in which an intended software is

developed.

In SDLC a series of steps is followed to design and developed a

software product efficiently. These steps are given below

Communication:

First step where an organization or developers gets request for

desire software and negotiate all the terms and conditions.

Requirement Gathering:

In this step developers discuss about all the things used in a

require software. They study or collect information using

questionnaire etc. To collect required information.

Feasibility Study:

The software developer teams check whether the project is

financially, practically and technologically feasible for the

organization to take up.

Other algorithms are available for feasibility of a software project.

System analysis:

System analysis include understanding of software limitation,

learning system related problem, what changes to be done in

existing systems beforehand.

Software design:

To design the software product from the input and output (by

input mean’s gathering of requirement output mean’s the physical

and logical design of a project)

Coding:

This step know as programming phase, developers

write/implement the program to be it’s error free.

Testing:

An estimate says 50% of whole software development should be

tested.

Error may ruin the software critical level to its own removal

software testing is done. Testing could be done by coding experts.

Integration:

This mean’s a software can be joint with outer world entities, ie

for database or some other programs or libraries etc.

Implementation:

Installing software on user machine for his requirements.

Operation & maintenance:

Software is update time by time so a software product is more

operation and error free.

maintenance:

As time elapsed the software may decline on the performance

front it may go completely obsolete or it may need intense

upgrading.
