Glossary of Key Terms Kenneth J. Andrews EMP-5179-1-1 Glossary of Key Terms • 5-S: A workplace organization methodology where emphasis is placed on maximizing space and minimizing movement/travel • Andon lights / boards: A visual control device in a production area. • Autonomation: automation with a human touch. Refers to semiautomatic processes where the operator and machine work together. Autonomation allows man-machine separation. Also referred to as Jidoka. • Balanced plant: A plant where capacity of all resources are balanced exactly with market demand. • Balanced production: all operations or cells produce at the same cycle time. In a balanced system, the cell cycle time is less than takt time. • Bottleneck: Any resource whose capacity is equal to, or less than the demand placed on it. Kenneth J. Andrews EMP-5179-1-2 Glossary of Key Terms • Capacity Constraint Resources (CCR): A situation is which a series of non-bottlenecks, based on the sequence in which they perform their jobs, can act as a constraint. • Chaku – Chaku: A method of conducting single-piece flow, where the operator proceeds from machine to machine, taking the part from one machine and loading it into the next. • Constraint: Anything that limits a system from achieving higher performance, or throughput. It is also a bottleneck that most severely limits the organization's ability to achieve higher performance relative its purpose/goal. • Error- proofing: designing a potential failure or cause of failure out of a product or process. • Evaporating Clouds: A problem of method used in Theory of constraints. Same as Conflict Resolution Kenneth J. Andrews EMP-5179-1-3 Glossary of Key Terms • External Setup (OED): Die setup procedures that can be performed while machine is in motion. OED - "outer exchange of die" (See Internal Setup). • Flow manufacturing: a manufacturing methodology that pulls items from suppliers through a synchronized manufacturing process to the end product. The principle goal is faster response to customer demand. • Heijunka: Keeping total manufacturing volume as constant as possible. [Same as Production Smoothing] • Hoshin Kanri: A strategic planning approach that integrates the practices of leadership with the practices of management. • Information Management Task: The task of taking a specific product from order-taking through detailed scheduling to delivery. [See Value Stream]. Kenneth J. Andrews EMP-5179-1-4 Glossary of Key Terms • Internal Setup (IED): Die setup procedures that must be performed while machine is in stopped. IED - "inner exchange of die" (See External Setup). • Jidoka: Stopping a line automatically when a defective part is detected. [Same as Autonomation] • Kaikaku: A radical improvement, usually applied only once within a value stream. [Same as Flow Kaizen] • Kaizen: Japanese term for incremental improvement. A team approach to quickly tear down and rebuild a process layout to function more efficiently. • Kanban: techniques named after the Japanese word for card or communication. Stocking technique using containers, cards and electronic signals to make production systems respond to real needs and not predictions and forecasts. Kenneth J. Andrews EMP-5179-1-5 Glossary of Key Terms • Just-in-Time (JIT): manufacturing method where downstream operations pull required parts needed from upstream operations at the required time. Implementing JIT requires most features of lean manufacturing. • Lean: Producing the maximum sellable products or services at the lowest operational cost, while optimizing inventory levels. • Mistake-proofing: any change to an operation that helps the operator reduce or eliminate mistakes. • Muda: Anything that interrupts the flow of products and services through the value stream and out to the customer is designated muda or waste. • Nagara System: A production system where seemingly unrelated tasks can be produced by the same operator simultaneously. • One piece flow: Producing one unit at a time, as opposed to producing in large lots. Kenneth J. Andrews EMP-5179-1-6 Glossary of Key Terms • Pitch: The pace and flow of a product. • Poka-Yoke: Techniques to mistake-proof a process. • Policy Deployment: The selection of goals, projects to achieve the goals, designation of people and resources for project completion, and establishment of project metrics. (Same as Hoshin Kanri). • Quality Function Deployment (QFD): Using a cross-functional team to reach consensus that final engineering specification of a product are in accord with the voice of the customer. • Quick Changeover: The ability to change tooling and fixtures rapidly (usually minutes), so multiple products can be run on the same machine. • Resource Activation: Using a resource regardless of whether throughput is increased. (See Resource Utilization). • Resource Utilization: Using a resource in a way that increases throughput . (See Resource Activation). Kenneth J. Andrews EMP-5179-1-7 Glossary of Key Terms • Right-Size: Matching tooling and equipment to the job and space requirements of lean production. • Sensei: An outside master or teacher that assists in implementing lean practices. • Shusa: The leader of the team whose job is to design and engineer a new product and it into production. • Single Minute Exchange of Dies (SMED): The reduction in die set-up time. Set-up in a single minute is not required, but is used as a reference. • 6 Sigma: A structured process improvement program for achieving virtually zero defects (3.4 parts per million) in manufacturing and business processes. • Standard operations: Clearly defined operations and standardized steps for both workers and machines. Kenneth J. Andrews EMP-5179-1-8 Glossary of Key Terms • Standard Work: Specifying tasks to the best way to get the job done in the amount of time available while ensuring the job is done right the first time, every time. • Sub-Optimization: A condition where gains made in one activity are offset by losses in another activity or activities, created by the same actions creating gains in the first activity. • Takt time: Takt is German for pace. Takt time defines the manufacturing line speed and the cycle times for all manufacturing operations. Takt time is computed as: Available work time per day / daily required demand (parts/day). • Theory of Constraints (TOC): A lean management philosophy that stresses removal of constraints to increase throughput while decreasing inventory and operating expenses. • Value Analysis: Analyzing the value stream to identify value added and non-value added activities. Kenneth J. Andrews EMP-5179-1-9 Glossary of Key Terms • 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 to determine the value added to a product as it goes through a manufacturing process. • Visual Controls: Displaying the status of an activity so every employee can see it and take appropriate action. • Waste: Anything that uses resources, but does not add real value to the product or service.
