How do you divide tasks by difficulty level for your projects?

To categorize tasks by difficulty level, I usually use the following criteria:

• Simple tasks: require basic knowledge and do not contain complex logic, such as fixing minor bugs or writing simple methods.
• Medium difficulty: involve working with multiple components, require understanding of architecture, and may include optimization.
• Complex tasks: require a deep understanding of the system, designing new modules, or refactoring complex code.

This division helps in planning time and distributing tasks among team members considering their experience.
