Standard Work
Standard work, or standardised work, is the documented current best method for performing a task safely and with consistent quality, defined in lean manufacturing by takt time, the work sequence and the standard amount of work in process.
In the Toyota Production System, standardised work has three elements: takt time, the pace required by customer demand; the work sequence, the order in which an operator performs tasks within the cycle; and standard work in process, the minimum material needed within the process to keep work flowing. Common documents include the standardised work chart, which shows the operator's path through the workstation, the standardised work combination table, which shows manual, machine and walking time, and job instruction sheets.
Standard work makes performance predictable, supports training and provides the baseline for improvement: without a defined standard, it is impossible to tell whether a change is better or whether a problem is an abnormality. It is used on assembly lines, in machining cells, for maintenance tasks and for changeovers, and supervisors use it to audit processes and coach staff.
Standard work should be written with the people who do the job and updated whenever an improvement is proven, so that it represents the current best method rather than a fixed rule. Overly detailed documents that are not used in practice offer little value; visual, concise instructions work better. Safety-critical steps and quality checks should be clearly identified, and the OEM documentation governs any work on machines.
Key points
- Documents the current best method for safe, consistent work.
- Three elements: takt time, work sequence and standard work in process.
- Provides the baseline against which improvements and abnormalities are judged.
- Updated whenever an improvement is proven.
Where AiVibe comes in
AiVibe designs and manufactures the AiAmbA AI Factory as the OEM: edge devices plus AI agents that let people talk to PLC, CNC and robot controllers in plain language. Existing lines are retrofitted with edge devices, and a trained operator confirms every change an agent proposes.
