Standard Work / Standardized Work
Standard Work documents the current best-known way to perform a task. It defines the sequence, timing, and inventory needed to produce consistent results safely and efficiently.
Standard Work is the foundation for all improvement in Lean. Without a defined standard, there is no baseline to improve from -- every operator does the work differently, and variation hides waste. Standard Work makes the current method explicit and repeatable.
A Standard Work document typically contains three elements: Takt time (the pace), work sequence (the order of steps), and standard WIP (the minimum inventory needed to keep the process running smoothly).
Critically, Standard Work is not static. It represents the best method known today -- and it is expected to change. When a Kaizen improvement finds a better way, the standard is updated immediately. The standard is a living document, not a bureaucratic constraint.
Standard Work also serves as a training tool: New employees learn the documented method rather than picking up different habits from different colleagues. This reduces the learning curve and ensures consistent quality from day one.
Practical Example
An assembly station has 6 operators performing the same task with cycle times ranging from 48 to 73 seconds. After documenting Standard Work based on the best operator's method, all operators are trained on the new standard. Cycle times converge to 50-55 seconds, and defect rate drops by 40%.
How Leanshift Helps
Leanshift captures precise cycle times per operator and step, revealing the variation that Standard Work eliminates. The documented current state becomes the baseline against which every KATA improvement is measured.
Frequently Asked Questions
Is Standard Work the same as a work instruction?
Not exactly. Work instructions describe how to do a task. Standard Work additionally includes takt time, work sequence, and standard WIP -- it connects the method to the production system's rhythm and flow.
Does Standard Work stifle creativity?
The opposite. Standard Work frees creativity by providing a stable baseline. Improvements are tested against the standard, and if they work, the standard is updated. Without a standard, improvements cannot be verified.
Who creates Standard Work?
The people who do the work, supported by a coach. Standards imposed from above without operator input are rarely followed. The best Standard Work comes from observing the best current practice and making it the norm.

Takt Time
Takt time is the pace at which a product must be completed to meet customer demand. It is determined by the market, not by the machine.
Cycle Time
Cycle time measures how long a single process step actually takes -- from start to finished result. It is the foundation of every process analysis.
Kaizen
Kaizen means 'change for the better' and describes the philosophy of continuous, incremental improvement by all employees -- every day, everywhere.
