What is standard work in operations management?
Standard work is the documented best-known method for completing a task, including the sequence of steps, the time each step should take, and the quality standards it must meet. It originated in lean manufacturing (Toyota Production System) and applies to any repeatable process. Standard work differs from SOPs by emphasizing timing, cycle time, and continuous improvement.
How does standard work differ from an SOP?
| Standard Work | SOP | |
|---|---|---|
| Origin | Lean manufacturing (Toyota) | Regulated industries (FDA, ISO) |
| Focus | Efficiency and timing | Compliance and consistency |
| Includes timing | Yes — cycle time per step | Usually not |
| Includes quality checks | Built into each step | Often a separate checklist |
| Updated by | The worker performing the task | Management or documentation team |
| Goal | Continuous improvement (kaizen) | Standardization and compliance |
| Format | Work combination sheet, standard work chart | Written procedure with screenshots |
How do you apply standard work to knowledge work?
Standard work was designed for manufacturing floors, but the principles translate to any repeatable process:
- Document the current best method — Record how your top performer completes the task using Glyde
- Establish the baseline time — How long does each step take when done correctly?
- Identify waste — Which steps add no value? Unnecessary approvals, redundant data entry, waiting for access?
- Standardize — Everyone follows the documented method until a better method is proven
- Improve — When someone finds a faster or better approach, update the standard and re-document
The key principle: standard work is not permanent. It is the best method right now, designed to be improved. This mindset prevents documentation from becoming outdated because updates are expected, not exceptional.
