The delegation of authority on the basis of custom, conventions or usage is known as

oral delegation
written delegation
downward delegation
sideward delegation

The correct answer is: A. oral delegation

Oral delegation is the process of assigning tasks or responsibilities to someone verbally. It is a common form of delegation, especially in small businesses or organizations where there is a high level of trust between employees.

Oral delegation can be effective when the task or responsibility is relatively simple and straightforward. However, it can be less effective when the task is more complex or requires a high level of skill or expertise. This is because it can be difficult to ensure that the person who is being delegated to understands the task fully and has the necessary skills to complete it.

In addition, oral delegation can be more difficult to track and monitor than written delegation. This is because there is no written record of the delegation, which can make it difficult to determine who is responsible for what and to assess the progress of the task.

Overall, oral delegation can be an effective way to assign tasks or responsibilities when the task is relatively simple and straightforward. However, it is important to be aware of the potential risks associated with oral delegation, such as the risk of misunderstandings and the difficulty of tracking and monitoring progress.

Here is a brief explanation of each option:

  • Oral delegation is the process of assigning tasks or responsibilities to someone verbally. It is a common form of delegation, especially in small businesses or organizations where there is a high level of trust between employees.
  • Written delegation is the process of assigning tasks or responsibilities to someone in writing. It is a more formal form of delegation and is often used when the task is more complex or requires a high level of skill or expertise.
  • Downward delegation is the process of delegating tasks or responsibilities to someone who is lower in the organizational hierarchy. It is a common form of delegation and is often used to empower employees and to get things done more quickly.
  • Sideward delegation is the process of delegating tasks or responsibilities to someone who is at the same level in the organizational hierarchy. It is a less common form of delegation, but it can be useful when there is a need to share expertise or to get a different perspective on a task.
