Software development methodologies are ways of organizing how a team creates a piece of software or a program, so that it is done as quickly and efficiently as possible. There are a lot of different software development methodologies, and each one has different steps that the team should follow. The team might look at the problem and decide what the customer wants from the software, figure out how to make it work, write the instructions and code to make the software work, test it to make sure it works, and then release it to the customer. Following a software development methodology helps the team make sure all the steps are done correctly and complete the project with the highest quality possible.
