What is the function of headings and subheadings in a technical document?

Headings and subheadings play a crucial role in organizing a technical document by establishing a clear hierarchy of information. They create a structured format that helps readers easily navigate through different sections and understand the relationships between various topics. This organization enables readers to quickly locate specific information, which is especially important in technical writing where clarity and accessibility are paramount. By guiding the reader through the content, headings and subheadings contribute significantly to the overall readability of the document, allowing users to assimilate information more effectively. This structured approach enhances the document's functionality, making it a practical resource for users who may need to reference particular data or concepts without having to read through all the text.
