The visual workplace is a continuous improvement paradigm that is closely related to lean manufacturing, the Toyota Production System (TPS), and operational excellence yet offers its own comprehensive methodology that aims for significant financial and cultural improvement gains. Introduced by Gwendolyn Galsworth in her 1997 book Visual Systems, [1] this system integrates and codifies the many iterations of visuality in the world of continuous improvement.
Visual communication rests on the natural inclination of humans to use pictures, graphics, and other images to quickly and simply convey meaning and understand information. For instance, look at the practices and applications that civil engineers have developed to handle complex human interaction on our roads and highways, [2] as well as the entire field of wayfinding in public spaces. [3]
The same logic eventually migrated into the workplace, notably in post-war Japan, and most saliently at Toyoda Motors where visual applications (visual devices) became a commonplace element in the Toyota Production System (TPS). [4] Other leading companies in Japan, such as Canon and Okidata, adopted many of the same practices. However, while visibility was clearly a part of Japan's success solution, it was only noticed—or cited in the literature—as a generalized principle and not a codified system or a framework of thinking. For example, Robert W. Hall, in his 1983 book, Zero Inventories, states: "Establishing visibility of all forms of production problems is very important. ... The entire idea is instant communication." [5]
Specifically, Japan's JIT (just-in-time) manufacturing approach had an easy-to-understand visual interface: andon (stacked lights), kanban (pick-up tickets for control material quantity), color-coding (to make the match between items), scheduling boards for daily production, easy-to-read labels on shelving, and lines on the floor to trace out locations. [6]
Japanese master practitioners also noted that visual devices made it easy to see the difference between normal and abnormal: "... abnormal conditions and problems need to be obvious enough to catch people's attention. Because of the emphasis on visual methods for quick information transfer, the practice is called 'management by sight' or 'visual control'." [7] Suzaki also compared the responsiveness of a well-tuned production system with the way the human body responds to stimuli and problems: "... Corrective action is taken right away, just as our muscles pull our hand away when we touch a hot plate." [7]
Michel Greif's book, The Visual Factory [8] conferred the name for the first time, though Greif's theme focused primarily on the ability of visual applications to increase the interest of hourly workers in their own performance and their participation in company improvement activities.
Throughout this period (1983–1991), Gwendolyn Galsworth was head of training and development at Productivity Inc. in Cambridge, Massachusetts, a publishing, training, and consulting firm known for bringing the work of Japan's manufacturing leaders to the United States.[ citation needed ] Galsworth headed study missions to Japan and observed visuality in Japan first-hand. She also had the opportunity of working one-on-one with many of Japan's seminal thinkers, including Taiichi Ohno, Ryuji Fukuda, and Shigeo Shingo. Shingo personally tasked Galsworth with developing his mistake proofing/poka-yoke methodology for western companies. [9] It was the synthesis of all these factors and influences that lead Galsworth to develop and codify the many threads of visuality into a coherent methodology of the visual workplace, an overall operational strategy and philosophy geared to help organizations continually achieve their goals through visual devices and systems.[ citation needed ]
Galsworth continues to be the main driving force behind the practice and articulation of workplace visuality, along with a network of individuals and companies loosely coupled as visual workplace practitioners around the world.[ citation needed ] The visual workplace is a large body of knowledge and know-how, with a strong guiding philosophy of continuous improvement with an emphasis on the centrality of the individual in the prosperity of the enterprise.[ citation needed ]
While virtually all major improvement paradigms in use in the West incorporate some element of visuality, the entire codified set of visual principles and practices, from the foundation of 5S through to visual guarantees (poka-yoke), rests on this definition: "The visual workplace is a self-ordering, self-explaining, self-regulating, and self-improving work environment—where what is supposed to happen does happen, on time, every time, day or night—because of visual devices." [10]
A visual workplace is defined by devices designed to visually share information about organizational operations in order to make human and machine performance safer, more exact, more repeatable, and more reliable. The more the process becomes visual, the more production velocity increases. [11]
This is accomplished in parallel with generating new levels of employee engagement and contribution, which in turn lead to improved alignment within the enterprise and significant bottom line benefits. In an effective visual workplace, this level of information can be seen and understood without coaching, supervision or the need for an explanation—at best, without speaking a word. [12]
The key principle is to install vital information visually as close to the point of use as possible. When a step-by-step methodology is applied, the visual workplace targets the elimination of the seventh waste, motion, defined as moving without working. [1]
Originally implemented and refined in manufacturing settings, the concept of the visual workplace is now taking hold in such wide-ranging venues as libraries [13] and hospitals. [14]
Lean manufacturing is a method of manufacturing goods aimed primarily at reducing times within the production system as well as response times from suppliers and customers. It is closely related to another concept called just-in-time manufacturing. Just-in-time manufacturing tries to match production to demand by only supplying goods that have been ordered and focus on efficiency, productivity, and reduction of "wastes" for the producer and supplier of goods. Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle, flow, and throughput times by further eliminating activities that do not add any value for the customer. Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service.
Kanban is a scheduling system for lean manufacturing. Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. The system takes its name from the cards that track production within a factory. Kanban is also known as the Toyota nameplate system in the automotive industry.
Kaizen is a concept referring to business activities that continuously improve all functions and involve all employees from the CEO to the assembly line workers. Kaizen also applies to processes, such as purchasing and logistics, that cross organizational boundaries into the supply chain. It has been applied in healthcare, psychotherapy, life coaching, government, manufacturing, and banking.
The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices. The TPS is a management system that organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers. The system is a major precursor of the more generic "lean manufacturing". Taiichi Ohno and Eiji Toyoda, Japanese industrial engineers, developed the system between 1948 and 1975.
Poka-yoke is a Japanese term that means "mistake-proofing" or "error prevention". It is also sometimes referred to as a forcing function or a behavior-shaping constraint.
5S is a workplace organization method that uses a list of five Japanese words: seiri (整理), seiton (整頓), seisō (清掃), seiketsu (清潔), and shitsuke (躾). These have been translated as 'sort', 'set in order', 'shine', 'standardize', and 'sustain'. The list describes how to organize a work space for efficiency and effectiveness by identifying and sorting the items used, maintaining the area and items, and sustaining the new organizational system. The decision-making process usually comes from a dialogue about standardization, which builds understanding among employees of how they should do the work.
Shigeo Shingo was a Japanese industrial engineer who was considered as the world’s leading expert on manufacturing practices and the Toyota Production System.
Muda is a Japanese word meaning "futility", "uselessness", or "wastefulness", and is a key concept in lean process thinking such as in the Toyota Production System (TPS), denoting one of three types of deviation from optimal allocation of resources. The other types are known by the Japanese terms mura ("unevenness") and muri ("overload"). Waste in this context refers to the wasting of time or resources rather than wasteful by-products and should not be confused with waste reduction.
Single-minute digit exchange of die (SMED) is one of the many lean production methods for reducing inefficiencies in a manufacturing process. It provides a rapid and efficient way of converting a manufacturing process from running the current product to running the next product. This is key to reducing production lot sizes, and reducing uneven flow (Mura), production loss, and output variability.
Genba is a Japanese term meaning "the actual place". Japanese detectives call the crime scene genba, and Japanese TV reporters may refer to themselves as reporting from genba. In business, genba refers to the place where value is created; in manufacturing, the genba is the factory floor. It can be any "site" such as a construction site, sales floor or where the service provider interacts directly with the customer.
Ohno Taiichi was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System, which inspired Lean Manufacturing in the U.S. He devised the seven wastes as part of this system. He wrote several books about the system, including Toyota Production System: Beyond Large-Scale Production.
Autonomation describes a feature of machine design to effect the principle of jidoka (自働化)(じどうか jidouka), used in the Toyota Production System (TPS) and lean manufacturing. It may be described as "intelligent automation" or "automation with a human touch". This type of automation implements some supervisory functions rather than production functions. At Toyota, this usually means that if an abnormal situation arises, the machine stops and the worker will stop the production line. It is a quality control process that applies the following four principles:
Value-stream mapping, also known as material- and information-flow mapping, is a lean-management method for analyzing the current state and designing a future state for the series of events that take a product or service from the beginning of the specific process until it reaches the customer. A value stream map is a visual tool that displays all critical steps in a specific process and easily quantifies the time and volume taken at each stage. Value stream maps show the flow of both materials and information as they progress through the process.
Cellular manufacturing is a process of manufacturing which is a subsection of just-in-time manufacturing and lean manufacturing encompassing group technology. The goal of cellular manufacturing is to move as quickly as possible, make a wide variety of similar products, while making as little waste as possible. Cellular manufacturing involves the use of multiple "cells" in an assembly line fashion. Each of these cells is composed of one or multiple different machines which accomplish a certain task. The product moves from one cell to the next, each station completing part of the manufacturing process. Often the cells are arranged in a "U-shape" design because this allows for the overseer to move less and have the ability to more readily watch over the entire process. One of the biggest advantages of cellular manufacturing is the amount of flexibility that it has. Since most of the machines are automatic, simple changes can be made very rapidly. This allows for a variety of scaling for a product, minor changes to the overall design, and in extreme cases, entirely changing the overall design. These changes, although tedious, can be accomplished extremely quickly and precisely.
Norman Bodek was a teacher, consultant, author and publisher who published over 100 Japanese management books in English, including the works of Taiichi Ohno and Dr. Shigeo Shingo. He taught a course on "The Best of Japanese Management Practices" at Portland State University. Bodek created the Shingo Prize with Dr. Vern Beuhler at Utah State University. He was elected to Industry Week's Manufacturing Hall of Fame and founded Productivity Press. He was also the President of PCS Press. He died on December 9, 2020, at the age of 88.
Lean dynamics is a business management practice that emphasizes the same primary outcome as lean manufacturing or lean production of eliminating wasteful expenditure of resources. However, it is distinguished by its different focus of creating a structure for accommodating the dynamic business conditions that cause these wastes to accumulate in the first place.
Lean product development (LPD) is an approach to product development that specializes in minimizing waste. Other core principles include putting people over the product and creating new values in services and physical products. This method of product development has been adopted by companies such as Toyota
Akira Kōdate (高達秋良、こうだて・あきら) was born in Kanagawa District, Japan on 6 October 1925. He is an engineer and a Japanese business manager, considered one of the greatest international experts in R&D and production management, as well as a master of lean thinking-related methodologies. Since 1953, he has been working as a consultant with the Japan Management Association (JMA) and JMA Consultants Inc, where he works as a principal consultant and technical advisor.
Design for lean manufacturing is a process for applying lean concepts to the design phase of a system, such as a complex product or process. The term describes methods of design in lean manufacturing companies as part of the study of Japanese industry by the Massachusetts Institute of Technology. At the time of the study, the Japanese automakers were outperforming the American counterparts in speed, resources used in design, and design quality. Conventional mass-production design focuses primarily on product functions and manufacturing costs; however, design for lean manufacturing systematically widens the design equation to include all factors that will determine a product's success across its entire value stream and life-cycle. One goal is to reduce waste and maximize value, and other goals include improving the quality of the design and the reducing the time to achieve the final solution. The method has been used in architecture, healthcare, product development, processes design, information technology systems, and even to create lean business models. It relies on the definition and optimization of values coupled with the prevention of wastes before they enter the system. Design for lean manufacturing is system design.
Gwendolyn Galsworth is the American president and founder of Visual Thinking Inc and an author, researcher, teacher, consultant, publisher and thought leader in the field of visuality in the workplace and visual management. Her books, which have won multiple Shingo Prize awards in the Research and Professional Publication category, focus on conceptualizing and codifying workplace visuality into a single, comprehensive framework of knowledge and know-how called the "visual workplace."
