Lean

  • Title / definition
    Lean (not an acronym but a business model).
     
    Lean is a business model and collection of methods that aim to achieve customer value through helping to eliminate waste while delivering quality products on time and at least cost; lean management embodies these principles.
     
    Type
    Framework
     
    Owner
    Lean has no specific owner. Lean manufacturing is a management philosophy derived mostly from the Toyota Production System (TPS).
     
    Brief history and description
    The principles of lean have been widely disseminated in the international best-seller book called “The Machine That Changed the World”, co-authored by Womack, Jones, and Roos, which was published in 1990. There is no formal methodology.
     
    Lean focuses on maximizing customer value while minimizing waste. It means creating more value for customers with fewer resources. A lean organization understands customer value and focuses its key processes to continuously increase it. The ultimate goal is to provide perfect value to the customer through a perfect value creation process that has zero waste.
     
    To accomplish this, lean thinking changes the focus of management from optimizing separate technologies, assets, and vertical departments to optimizing the flow of products and services through entire value streams that flow horizontally across technologies, assets, and departments to customers.
     
    Lean IT is the extension of lean manufacturing and lean services principles to the development and management of information technology (IT) products and services. Its central concern, applied in the context of IT, is the elimination of waste, where waste is work that adds no value to a product or service.
     
     Lean management is very much about asking the right questions rather than providing the right answers.
     
    A five-step thought process guides the implementation of lean thinking (see Figure).

    The Lean five step process
    As value is specified, value streams are identified, wasted steps are removed, and flow and pull are introduced, begin the process again and continue it until a state of perfection is reached in which perfect value is created with no waste.
     
    Target Audience
    Process owners and teams involved in process improvement.
     
    User communities and groups
    Lean knowledge-sharing is enabled by the Lean Enterprise Institute and Lean Global Network, not-for-profit organizations whose aim is to accelerate the diffusion of lean knowledge. There are local chapters of the lean community in many countries all over the world. The Lean Enterprise Institute, Inc. founded by James P. Womack in 1997, is a nonprofit education, publishing, research, and conference organization.
