进程 (jìn chéng) literally combines 进 (jìn, 'to advance, enter') and 程 (chéng, 'course, stage, or procedure'), together conveying the idea of forward movement through a process or development over time. It refers to the ongoing progress or unfolding stages of an event, project, natural phenomenon, or abstract change — emphasizing continuity and temporal progression rather than a static state.

This word is commonly used in formal, academic, technical, and administrative contexts: for example, describing the advancement of scientific research, the development of a disease, the evolution of social reforms, or the execution of a software program (where it also means 'process' in computing). While it can occasionally appear in everyday speech, it carries a neutral-to-formal register and is rarely used for simple personal activities like 'making dinner' or 'walking to school' — those would use 进展 (jìn zhǎn) or 更好 (gèng hǎo) instead.
