LIST OF GLOSSARY: Batch and Queue: The mass production process of making large lots of a part and then sending the batch to wait in the queue until the next operation in the production process begins. Bottleneck: Any part of a production line that adversely affects throughput. Cell: An arrangement of machinery, tools, and personnel designed for most logically and efficiently to complete a production sequence. Cellular Manufacturing: An approach where manufacturing work centers (cells) have the total capabilities needed to produce an item or group of similar items. Changeover Time: The time that elapses between the completion of one production run and the beginning of another production run. Just-in-Time: A production scheduling concept that calls for any item needed at a production operation –whether raw material, finished item, or anything in between, to be produced and available precisely when needed. Kanban: A Japanese term meaning “visual record” or “card.” In Lean Manufacturing Kanban has come to means “Signal.” Kanban System: A system that controls production inventory and movement through the visual control of operations. Page 6 of 8 Mistake Proofing (Poka - Yoke): Technology and procedures designed to prevent defects and equipment malfunction during manufacturing processes. Visual Controls: Displaying the status of an activity so every employee can see it and take appropriate action. Non-Value-Added: Activities or actions taken that add no real value to the product or service; these activities are termed as waste. One-Piece Flow: A situation in which products proceed, one complete product at a time, through various operations in design, order-taking, and production, without interruptions, backflows, or scrap. This is also known as single-piece flow. Value Stream: The set of specific actions required to bring a specific product through three critical management tasks of any business: problem solving, information management, and physical transformation. Value Stream Mapping: A process mapping method used to document the current and future states of the information and material flows in a value stream from customer to supplier. Work In Progress (WIP): Production material in the process of being converted into a saleable product. Changeovers: Switching from producing one part (product) to another. Flow Chart: A visual representation of the steps in a process or system. Gemba: A Japanese term that means “Real Place” or “Where the action takes place.” Page 7 of 8 Inventory: The money and materials invested in by a company in order to create products for sale.

Standard Allowed Minutes (SAM): This is the amount of time allowed to perform a given task (e.g., a sewing operation) as determined by engineering. Standard Allowed Hours SAH is the time expressed in hours and Standard Allowed Minutes SAM is the time expressed in minutes. Personal Fatigue and Delay (PFD): PFD allowance is the adjustment done to the normal time to obtain the standard time for the purpose to recover the lost time due to personal needs, fatigue, and unavoidable delays. By providing a small increase to the normal time in each cycle, the worker can still be able to cover lost time and complete the work assigned to him. Throughput Time: The time period required for a material, part, or subassembly to pass
