In technical communication, should visuals always be included for better understanding?

In technical communication, the decision to include visuals should be based on necessity rather than a blanket rule. The rationale behind this approach is that while visuals can greatly enhance understanding by providing clarity and aiding retention, they may not always be required for every piece of information or context. Including visuals when they add significant value—such as clarifying complex processes or depicting data trends—is essential. However, for straightforward information, excessive visuals can create distractions and overwhelm the reader.

By focusing on including visuals only when they are necessary, technical communicators create a balance between text and graphical elements, ensuring that visuals serve their purpose effectively without detracting from the message. This approach also promotes conciseness and relevance, keeping the audience engaged and well-informed.
