# List of software development philosophies

This is a list of approaches, styles, methodologies, and philosophies in software development and engineering. It also contains programming paradigms, software development methodologies, software development processes, and single practices, principles, and laws.
Some of the mentioned methods are more relevant to a specific field than another, such as automotive or aerospace. The trend towards agile methods in software engineering is noticeable, however the need for improved studies on the subject is also paramount. Also note that some of the methods listed might be newer or older or still in use or out-dated, and the research on software design methods is not new and on-going.

## Software development methodologies, guidelines, strategies
### Large-scale programming styles
