What is the software development steps?

Answer 1

Summary of software development steps:

1) Requirements: state what you want to do. What inputs will be provided, what outputs are desired.

2) Design: state how you want to do it. The platform (computer and operating system), the language(s) to be used, the architecture of the software to be built; e.g., one program to perform all the work in the requirements -- or multiple programs to accomplish specific work. Detailed design is sometimes itemized as a separate step -- but includes outlining the internal flow of the programs identified in the design architecture.

3) Implementation: code, compile, and execute software.

4) Implementation test: (or unit test) test the paths of the code to verify code execution stability -- if some input is provided to the code that you would not expect based on the design or requirements -- does the code handle the situation and keep the system stable?

5) Design testing: putting the code together in the system that was designed in step 2 and verify that it performs to the design.

6) User or verification testing: execute the software and see if it does what the user asked for in the requirements.
