What stages of production do you know?

The main stages of production (in the context of systems analysis and development) include:

1. Requirements gathering and analysis — identifying the needs of the customer and users.
2. System design — creating architecture and technical solutions.
3. Development — writing code and implementing functionality.
4. Testing — verifying the functionality and quality of the product.
5. Deployment — installing and launching the system in the operational environment.
6. Support and maintenance — fixing bugs, updates, and improvements.

Depending on the methodology (Waterfall, Agile, etc.), these stages may overlap or be iterative.
