Class Vocabulary

Term	Definition
changeover time	The time it takes to convert a machine from one process to another. Changeover may require switching fixtures, tools, programming, and other aspects of the manufacturing process.
cycle time	The actual time it takes to perform a task and forward it to the next step. One of the major goals of lean is to match cycle time to the customer's requirements.
future state	The improved condition for a process. A future-state flow chart maps out the manufacturing process as it should be, with all possible flaws and errors eliminated.
information symbol	A type of value stream mapping symbol that indicates the form, flow, and direction of communication and data. A jagged arrow, which represents electronic information, is an example of an information symbol.
material symbol	A type of value stream mapping symbol that indicates the origin, location, and movement of raw materials and parts within the system. A triangle, which represents inventory, is an example of a material symbol.
metric	A measured variable that is tracked and can be used to detect errors or variation and make improvements.
muda	A Japanese term meaning waste.
non-value added	Activities that do not contribute to the product or the process and should therefore be eliminated. Non-value added steps are waste.
non-value added but essential	Production activities ensuring that the value-added steps have been properly completed. For example, inspection does not contribute to the product, but it is necessary unless the process can be improved to the point where inspection can be eliminated.
present state	The current condition of a process. A present-state flow chart captures all of the details of a manufacturing process just as it is at the moment the chart is produced, including any flaws or errors.
process flow chart	A visual representation of the steps required to manufacture a product.
process map	A flow charting method that uses general symbols and arrows to show the flow of the manufacturing process.
process symbol	A type of value stream mapping symbol that indicates the actions that take place or the locations where processes occur. A U-shaped symbol, which represents a cell, is an example of a process symbol.
product family	Products that are grouped together based on the fact that they use the same machines or processes.
spaghetti diagram	A flow charting method that uses a continuous line to trace the path of a part through all phases of manufacturing. Spaghetti diagrams expose inefficient layouts and large distances traveled between steps.
value added	Any step in the production process that improves the product for the customer.
value stream map	A sophisticated flow charting method that uses symbols, metrics, and arrows to help visualize processes and track performance. This method helps determine which steps add value and which do not.
