What is the primary purpose of standard operating procedures (SOPs)?

• A. To provide step-by-step instructions for tasks
• B. To document worker performance
• C. To replace maintenance records
• D. To define product features

Answer: (A)

The main idea behind standard operating procedures is to provide consistent, repeatable, step-by-step instructions for performing a task. In maintenance for supply chain automation equipment, this means every technician follows the same sequence, uses the same tools, observes the same safety measures, and checks for the same results. With SOPs, you reduce variation, prevent skipped steps, and make training easier because new staff can learn the exact process quickly. They also support compliance and audits by showing a defined method was used every time.

While SOPs can inform how to document work and support training, their primary purpose is not to record performance, replace maintenance logs, or define product features. For example, an SOP for servicing a robot arm would specify who does the work, what tools are used, the order of steps, safety checks, and acceptance criteria, ensuring the task is done correctly every time.
