Standardised work involves following procedures consistently and, therefore, employees can identify the problems promptly. Kaizen activities include measures for improving equipment, as well as improving work procedures.
Kanban is a tool used in the Toyota Production System to operate the production system as a pull system. It is a system that provides for conveying information between processes and automatically orders parts as they are used. Every item or box of items that flows through our production process carries its own kanban. Kanbans are removed from items as they are used or transported and go back to the preceding processes as orders for additional items.

Takuto-time or takt-time is a unit of time "how much time is used to complete a job" that is determined based on regular operational time and the amount required.
Tanokoka or multi-skilled operator is to create flow and increase efficiency, one worker must be able to operate several machines, then be able to perform various jobs in his work area.
This is a method of transportation according to a predetermined schedule. The amount of transportation does not depend on the amount of consumption at that time. In cases where the workplaces are far apart, this method is used for ease of operation.
This is a mechanism that is used when problems are found (eg work delays, quality problems) on the conveyor line, the conveyor does not stop immediately but waits until it reaches a predetermined point and stops.
Japanese for waiting. It is a condition when the operator does nothing but wait, such as waiting for the engine cycle, fixing the equipment, or waiting for the delivery of parts.
Tsukuri-Sugi-No-Muda can be interpreted as Muda over production. If it is made to produce too much it will result in an increase in stock, resulting in wastage. If we produce something that is not needed in the near future, and then there is a change in production planning then more stock will become Muda.
Temachi-No-Muda or Muda waiting is where workers cannot start work because there are incomplete tools, materials,, instructions, etc to do the process themselves. Waiting time will become Muda because it wastes time and energy.
