Part 1: What is Kanban
Kanban visualizes work processes and improves workflow efficiency. At its core, Kanban focuses on how tasks move through various stages, making managing and optimizing work easier.
A traditional Kanban board includes columns with labels such as 'To Do,' 'In Progress,' and 'Done,' representing steps in a process. Tasks are depicted as cards that move across these columns, providing a clear visual of the workflow. This approach helps teams identify bottlenecks and streamline operations.
The primary goal of Kanban is to optimize processes and minimize inefficiencies. A key principle is managing "Work in Progress" (WIP), which limits the number of tasks handled simultaneously. This prevents overload, reduces lead times, and enhances scheduling.
Kanban emphasizes continuous improvement, encouraging teams to refine processes over time. Widely applicable in software, manufacturing, and other fields, Kanban is a flexible, customizable system aimed at boosting organization and productivity.
Part 2: History of Kanban
The Kanban system was developed in the mid-20th century by Toyota engineer Taichii Onho. It originated at Toyota Motor Corporation, a Japanese car manufacturer. The term “Kanban” combines two Japanese words: Kàn (sign) and Bǎn (board), reflecting the essence of the method.
In the 1940s, Toyota sought to increase productivity and reduce unnecessary material usage. Taichi Ohno introduced Kanban cards for workers to request more parts, minimizing excess inventory.
This approach eventually evolved into Toyota’s just-in-time (JIT) inventory system, inspired by American supermarkets where stock is replenished based on demand rather than periodic restocking.
This innovation transformed manufacturing, shifting from a push system (producing based on forecasts) to a pull system (producing based on demand). Initially implemented at Toyota, the system proved efficient, responsive, and waste-free, influencing the automotive industry and beyond.
Into the IT Industry
In the early 2000s, David J. Anderson adapted Kanban for IT and software development, emphasizing visualizing workflows, limiting WIP, and enhancing efficiency. Today, Kanban is widely used across industries for its simplicity, adaptability, and ability to boost productivity.
Part 3: Purpose of Kaban
Kanban aims to simplify work processes by making them easy to visualize and share, enabling more effective management.
Tools like the Kanban board transform workflows into visual processes, helping identify bottlenecks and apply existing knowledge to improve efficiency.
A primary goal of Kanban is to prevent workflow over-processing. By limiting work in progress (WIP), teams can focus on fewer tasks simultaneously, enhancing efficiency and reducing lead times. This systematic approach minimizes bottlenecks, accelerates workflow, and ensures smoother task completion.
Kanban also emphasizes continuous improvement. By monitoring and analyzing workflows periodically, teams can make incremental changes that refine processes over time.
Additionally, the visual nature of Kanban fosters better communication and collaboration, offering a clear overview of tasks and enabling teams to brainstorm solutions together. This results in better decisions, increased accountability, and improved outcomes.
Part 4: Types of Kanban Systems
Kanban systems have evolved from simple workflow management systems to six different types to meet the needs of industries.
Production Kanban
In manufacturing, it is used to trigger the start of production or reorder of stock; products are only manufactured according to the demand as a way of preventing over-production.
Withdrawal Kanban
This type is used to show the transfer of materials and products from one step to another, which is essential in managing the movement of products within a firm or between different firms in a supply chain.
Supplier Kanban
This type of Kanban is an expanded one. It goes beyond the company's internal supply chain. It helps include external suppliers in the lean inventory delivery management process. Its goal is to deliver the materials needed for production.
Emergency Kanban
Emergency Kanban is intended to be used only in extraordinary circumstances where there is an immediate need for the material or a deficiency has been identified, helping to establish priorities.
Throughput Kanban
Mainly concerned with the throughput of work in a system, this type is frequently found in service-centered businesses to improve the functioning of processes.
Express Kanban
To address the high-priority issues, Express Kanban allows for prioritized work on the items that are important and need to be completed rather quickly, but this is done without interfering with the general process.
Such Kanban systems enable organizations to optimize the processes, response time, and productivity to their preferences.
