Standard work
Standard work or standardized work is a lean manufacturing is the current, documented best known method for executing a task. The purpose is to create a consistent, efficient, and repeatable process that can be utilized by anyone enabling workers to reduce waste, improve quality, and increase productivity.[1][2][3][4]
Employees may be resistant to the deployment of standard work due resistance to change.[5][6]
Aside from creating stability, standardized work provides a baseline for kaizen or continuous improvement. Without a stable, repeatable process it is not possible to assess whether a change to a job has helped or hurt it.
There are three elements to standardized work:[7]
- Takt Time — the pace of customer demand
- Standard Work in Process (SWIP) — the minimal amount of inventory required to ensure a smooth flow
- Work Sequence — the steps to complete the job safely with quality within takt time
There are three standardized work sheets: [8]
- Standardized Work Chart —maps an operator's walk path to parts, tools, stations, and equipment, while documenting key points for safety and quality.
- Standardized Work Process Capacity Sheet — calculates whether equipment can keep up with the pace of demand
- Standardized Work Combination Table — records an operator's manual work alongside automated machine work, and walking to assess if a job can be completed within takt time.
Standard work is not the same as standard operating procedure. The latter details rules and technical requirements (e.g. a torque rating), while the former explains an operator's method and how he interacts with tools, equipment, and the product within takt time.
