In software engineering, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable. The principles are a subset of many principles promoted by American software engineer and instructor Robert C. Martin,[1][2][3] first introduced in his 2000 paper Design Principles and Design Patterns.[2][4]

The SOLID concepts are

The SOLID acronym was introduced later, around 2004, by Michael Feathers.[11]

Although the SOLID principles apply to any object-oriented design, they can also form a core philosophy for methodologies such as agile development or adaptive software development.[3]
