Task-oriented schemes are commonly used in task-based applications such as online banking platforms, job application portals, software interfaces, etc. For instance, in an online banking platform, the content is typically organized by tasks that users may want to accomplish, such as "Transfer Money", "Pay Bills", or "Check Account Balance".

Here are some best practices for implementing task-oriented schemes:

• Display the most important tasks users need to perform.
• Use clear, self-explanatory labels to guide users through tasks efficiently.
• Regularly test with real users to ensure the scheme meets their needs and is effective.
• Combine task-oriented schemes with topical or other organizational methods for a more comprehensive navigation system.
