A development process is a set of practices, roles and artifacts performed/created during development. **Important note:** General development methodology questions should be posted on Software Engineering SE or Project Management SE instead.
A software development process describes how one gets from the idea of software product to the actual software. Certain activities will most likely happen during any process: Requirements analysis, Specification, Implementation, Testing, Deployment. But the way how they happen, how they are named and when and how often they happen may differ widely.
You can't do software development without a development process, although the process often isn't formally defined or documented.
The V-Model, RUP, XP, Scrum and Kanban are often referred to as development processes although at least some of those are considered frameworks that can be the basis for a development-process.
Questions should be tagged with this tag if they relate to choosing or customizing a development process for a certain task.
It's easy to create very vague question in this topic area, so you should try extra hard to make the question specific.
