Final answer:
Task-oriented design focuses on completing specific tasks in a flexible manner, while waterfall design follows a sequential process. Task-oriented design allows for frequent iterations and changes, while waterfall design is more rigid and linear.
Step-by-step explanation:
Task-oriented design focuses on completing specific tasks in a flexible manner, allowing for frequent iterations and changes. On the other hand, waterfall design follows a sequential process and is more rigid and linear. Task-oriented design is suitable for small projects, while waterfall design is better for large projects. Additionally, task-oriented design is a newer approach, while waterfall design is an older and traditional approach.
