Study Notes
The Theory of Swift, Even Flow
- The theory states that the more swift and even the flow of materials through a process, the more productive that process is.
- Productivity rises with the speed of material flow and falls with increases in variability associated with the flow.
Understanding the Theory
- Work can be divided into value-added and non-value-added work.
- Value-added work transforms materials into good products, while non-value-added work includes tasks like moving, cataloging, inspecting, and reworking materials.
- Non-value-added work is considered waste, including the seven wastes: overproduction, waiting, transportation, unnecessary processing, stocks, motion, and defects.
Key Concepts
- Throughput time measures the speed of material flow from the starting point to completion and supply to customers or warehouses.
- Reducing throughput time increases productivity.
- Throughput time helps identify where flow has become retarded or blocked.
Variability and Bottlenecks
- Variability is measured by variance or standard deviation of timing or quantities demanded, or time spent in process steps.
- Narrowing variability by reducing demands and making production plans level and regular increases productivity.
- Processing like things together, without slowing down the process, also increases productivity.
Scientific Methods
- Scientific methods remove non-value-added motions and steps, and enable value-added steps to be done more quickly and with less exertion.
- Scientific methods are most effective when applied to value-added work, and have varying success when applied to non-value-added work.
- The theory is consistent with deductive laws of variability and bottlenecks.

Description
Explore the concept that the productivity of a process increases when materials flow swiftly and evenly through it. Learn how productivity is influenced by the speed and variability of material flow in various aspects such as labor, machines, and materials.
