Which statement is true regarding the use of instructions in Appian?

Using instructions in Appian is important for enhancing user experience and ensuring that tasks are completed effectively. The first statement highlights that instructions should be incorporated when the content is essential to completing a task. This approach helps users understand the purpose of the interface, what steps they need to take, and how to navigate through tasks effectively. Clear and concise instructions can guide users, reduce confusion, and ultimately improve the efficiency of task completion.

The emphasis on using instructions only when essential reflects a balanced approach to interface design, ensuring that users are provided with necessary information without overwhelming them. When instructions are contextually relevant, they add value by informing users what actions they need to take next, thereby supporting their interactions with the application.

In contrast, displaying instructions on every page regardless of their necessity may lead to user fatigue and a cluttered interface, making it difficult for users to focus on key tasks. Similarly, stating that instructions are mandatory for all user interfaces does not take into account situations where interfaces may be self-explanatory. Avoiding instructions altogether can also lead to misunderstandings or mistakes if users are unsure about how to proceed. Thus, the correct approach is to use instructions judiciously, emphasizing their utility when they significantly enhance task completion.
