There are various stages involved in developing a software , But generally a software is made by programming and the program by which is divided into different modules , Each carrying a function on its own,

These are the steps in brief :

*Analyzing or Understanding your software needs (i.e. Wat your end output is)

*Drawing Relevant Flowcharts for the pseudocode

*Coding the programs by splitting into different sub modules

*Debugging any minor bugs in the coding by running tests

*Testing the Final Verified coding

*Designing Interfaces and producing a output with the alpha or the first prototype of the software

*Finally preparing documentation, Marketing , claiming copyrights
