Does your system have an interface? Do you decompose tasks within a user story, or is it purely technical?

If the system has a user interface, then within the user story, task decomposition usually includes both functional and technical aspects.

A user story describes what the user wants to achieve, and based on it, the team breaks down the work into smaller tasks, which may include:

• Interface development (visual components, interactions)
• Logical data processing
• Integration with external systems
• Testing

Thus, decomposition is not only a technical story but a comprehensive process aimed at implementing a specific user scenario. It helps better plan work and monitor progress.
