Lean Thinking

1) Define value from the customer's perspective to eliminate waste 2) Map the value stream to identify and remove non-value-adding activities 3) Create flow by organizing work in a continuous sequence

Muda. It's the one word of Japanese you really must know. It sounds awful as it rolls off your tongue and it should, because muda means "waste," specifically any human activity which absorbs resources but creates no value. Eliminate waste. The foundation of lean thinking is identifying and eliminating muda - any activity that consumes resources without creating value for the customer. This requires precisely specifying value from the end customer's perspective for each product or service. Common types of waste include overproduction, waiting, unnecessary transport or motion, overprocessing, excess inventory, defects, and unused employee creativity. By ruthlessly eliminating non-value-adding activities, organizations can dramatically improve efficiency and effectiveness. Focus on the customer. Lean thinkers must resist the tendency to define value based on existing assets, technologies, or organizational structures. Instead, they should engage in dialogue with customers to truly understand their needs and what they are willing to pay for. This customer-centric view often reveals opportunities to eliminate entire steps or processes that don't contribute to customer value.

The value stream is the set of all the specific actions required to bring a specific product (whether a good, a service, or, increasingly, a combination of the two) through the three critical management tasks of any business: the problem-solving task running from concept through detailed design and engineering to production launch, the information management task running from order-taking through detailed scheduling to delivery, and the physical transformation task proceeding from raw materials to a finished product in the hands of the customer. Visualize the entire process. Value stream mapping involves documenting every step required to deliver a product or service, from concept to customer. This end-to-end view often reveals surprising amounts of waste, as most activities are typically non-value-adding. The goal is to create a "future state" map that eliminates as much waste as possible while still delivering customer value. Categorize activities. When analyzing the value stream, activities generally fall into three categories: Value-adding: Activities that directly contribute to what the customer values Necessary non-value-adding: Activities that don't create value but can't be eliminated yet (Type One muda) Non-value-adding: Pure waste that can be eliminated immediately (Type Two muda) Take action. Once the value stream is mapped, organizations should immediately eliminate Type Two muda, then work to reduce and eventually eliminate Type One muda over time. This often involves redesigning processes, realigning organizational structures, and challenging long-held assumptions about how work should be done.
