This document provides an introduction to ISO/IEC 29110, which defines standards for very small entities (VSEs) developing software. It discusses the three critical dimensions of process, roles, and responsibility. ISO/IEC 29110 aims to standardize processes for VSEs with up to 25 people. It has defined four profiles (Entry, Basic, Intermediate, Advanced) targeting different levels of VSEs. The next chapter will cover the project management process defined in ISO/IEC 29110.
