What is an engineering notebook used for?

An engineering notebook serves as a comprehensive record of all work related to a specific design project. It is essential for engineers to document their processes, ideas, sketches, calculations, and testing procedures as they evolve. This thorough documentation serves multiple purposes: it provides a clear trace of development, helps in tracking project progress, and serves as legal evidence of an engineer's work and innovations.

Such documentation is crucial not only for the engineer's reference but also for collaboration within teams and for future projects that may build on the current work. By maintaining a detailed and organized notebook, engineers can ensure continuity in projects and facilitate knowledge transfer among team members.
