What is the effect of technical writing that lacks a clear structure?

Technical writing that lacks a clear structure can significantly hinder communication and comprehension. A well-structured document allows readers to follow ideas logically, understand key messages, and retrieve information efficiently. When technical writing is disorganized, it can lead to confusion, as readers struggle to ascertain the relationships between concepts or find the information they need. This chaotic presentation may distract the audience from the main points, making it difficult to grasp the overall intent of the material. Consequently, the lack of structure undermines the effectiveness of the writing, as the reader may feel lost or overwhelmed, rather than engaged or informed.
