A work instruction is a document that provides a detailed description of a specific task, explaining who, when, where, and with what tools or methods the task should be performed, as well as any settings or parameters required. Work instructions are typically linked to processes, products, or specific workstations.

If needed, they also explain the purpose and guidelines. Since they are workplace-specific, they are readily available where they are needed. Additionally, they are required for QM-documentation. Work instructions differ from procedural instructions: While work instructions are designed to detail individual tasks, procedural instructions offer an overview of all steps or tasks involved in a procedure and present them in a sequential order.
