The term for breaking down a complex process into smaller, manageable tasks in software development is decomposition. This technique involves dividing a project into sub-tasks or modules, which can be tackled individually. By breaking down the development process, teams can address specific functionalities, facilitating easier implementation, testing, and maintenance. This practice enhances collaboration among team members and allows for a more organized approach, ensuring that each component can be developed iteratively. Decomposition is vital for implementing methodologies like Agile and Scrum, promoting adaptability and efficiency.
