Lean, Design, Quality

Transcript of Lean, Design, Quality
Essentially, lean manufacturing is centered on preserving value with less work. Lean manufacturing is a management philosophy derived mostly from the Toyota Production System (TPS) and identified as "Lean" only in the 1990s. Types of Waste While the elimination of waste may seem like a simple and clear subject it is noticeable that waste is often very conservatively identified. This then hugely reduces the potential of such an aim. The elimination of waste is the goal of Lean, and Toyota defined three broad types of waste: muda, muri and mura; it should be noted that for many Lean implementations this list shrinks to the first waste type only with corresponding benefits decrease Lean Leadership Continuous Improvement breaks down into
three basic principles:
Challenge: Having a long term vision of the challenges
one needs to face to realize one's ambition. To do so,
we have to challenge ourselves every day to see if
we are achieving our goals.
Kaizen: Good enough never is, no process can ever be thought perfect, so operations must be improved continuously, striving for innovation and evolution.
Genchi Genbutsu: Going to the source to see the facts for oneself and make the right decisions, create consensus, and make sure goals are attained at the best possible speed.
Respect For People is less known outside of Toyota, and essentially involves two defining principles:
Respect: Taking responsibility for other people reaching their objectives.Teamwork: This is about developing individuals through team problem-solving. Lean Goals Improve Quality Reduce Time Reduce Time Reduce Total
Costs Steps to archive lean systems The following steps should be implemented to create the ideal lean manufacturing system. Defects MURI = PREPARATION AND PLANNING MURA = QUALITY AND VOLUME MUDA = CONTROL The muda's seven elements Inventory Over Processing Motion Overproduction Waiting Transport Defects Design a simple manufacturing system Recognize that there is always room for improvement Continuously improve the lean manufacturing system design. JUST IN TIME Just in time (JIT) is a production strategy that strives to improve a business return on investment by reducing in-process inventory and associated carrying costs. KANBAN Between different points in the process, which tell production when to make the next part. Are usually 'tickets' but can be simple visual signals, such as the presence or absence of a part on a shelf. To meet JIT objectives, the process relies on signals or Kanban. Goals of JIT Focuses on continuous improvement
