Can you highlight the main principles on which the process of developing software solutions is based?

Main principles of software development:

• Requirements planning and analysis: understanding the task and goals.
• Modularity and responsibility separation: breaking down the system into independent parts.
• Code reuse: using libraries and components.
• Testing and debugging: verifying correctness and fixing errors.
• Iterative development: gradual improvement and addition of functionality.
• Documentation: maintaining clear documentation for support and development.

For example, in Python development, principles like DRY (Don't Repeat Yourself) and KISS (Keep It Simple, Stupid) are often applied to improve code quality.
