What are the main stages in the software development process?

The main stages of software development typically include:

1. Requirements analysis — gathering and clarifying customer requirements, understanding goals and objectives.
2. Design — creating the system architecture, selecting technologies, designing modules and interfaces.
3. Development (coding) — writing source code according to the design.
4. Testing — verifying functionality, finding and fixing bugs.
5. Deployment — deploying the product in the production environment.
6. Support and maintenance — fixing bugs, updates, improvements.

These stages can be implemented using different methodologies (waterfall, Agile, etc.), but generally reflect the software development life cycle.
