Lean Methodology focuses on enhancing customer value through resource optimization and is oriented on continuous organizational development and improvement. This is a combination of management tools, styles and techniques that create a more efficient and profitable organization.
Lean changes the way the organization operates and proposes the most effective way of allocating internal organizational functions that are created by team members themselves.
Briefly, Lean offers creation of better product/service by applying less resourcing.
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.
