Introduction:
There are many ways of developing software but of the most popular one that is being followed by a lot of companies is called waterfall model.
This method is easy to flow and no matter how big the project is it can be useful.
Most of the software developers use this method by capturing the requirements from the client, once the complete of set requirements are captured, the developer move on to design phase where the set of requirements have been completely designed.
After designing the next step is start coding by using different programming languages. After the coding is completed, the programs must be tested. When the testing is completed, the software is delivered to the client. Once is delivered to the client there could be some issues at the customer place. If that happens then the software enters the …show more content…
The programs are written in several programming languages, whichever has been selected and when the programmers finish coding, then programmers will move on to testing. The software organisation also do the review of the particular program and every individual programs have been tested, what we know as unit testing. According to website called (search software quality) unit testing is process that programmers use and is the smallest parts of an application, this process must be done manually but sometimes it can be done automated.

Testing:
The next move is testing, the software organisation will give this section to the testers and they will take over the code, and they will do a thorough test. Each module is independently under a test to check its functionality. When the test is completed, the software organisation will see whether the system is working in line with the requirements, which has been understood and analysed from the client’s place.

Maintenance phase:
When the software is tested, then the software is delivered to the
