The skills managers value is reflected in the way they recruit new employees. One noticeable shift last year was the widening of the gap between job postings for Lean versus Six Sigma. The data comes from The Avery Point Group. In their first year of reporting, 2005, they showed job Read more…
In traditional manufacturing, there is a tendency to run large lots, or batches. This occurs for a variety of reasons—large distances between processes, long setup times, or simply poor processes. When the batch is transferred to the downstream process, it sits in line. That is the ‘queuing’ part of batch Read more…
In less than a week, I get my braces off. I thought it would be done at that point, but my orthodontist told me that recent studies have shown that teeth will start shifting back to the original position as long as five years after the braces are removed, if Read more…
I’m sure you’ve heard many different definitions about what the meaning of Lean is. The strictest meaning will likely center around creating flow, or will possibly mention inventory reduction. I, however, subscribe to a far broader meaning of Lean. I view it as any effort to reduce waste and improve Read more…
Accounting is a necessary part of any business. It is critical to know if the actions a company is taking are making it profitable, or if they are causing the business to bleed cash. Accounting in the best of situations has its challenges. But the advent of Lean has made Read more…
Taiichi Ohno (February 29, 1912-May 28,1990) is considered by many to be the father of the Toyota Production System. He eventually rose to the rank of executive vice president in the company.
While Ohno had many innovative ideas and published several landmark books (see them and other books about him here), perhaps his biggest creative leap was integrating the American supermarket system of resupply into the automotive industry. He was able to lay the foundation for kanban systems, pull, and one-piece flow by changing the way components were supplied to production processes.
Lean tools are the individual components of a Lean system. The most common Lean tools are: 5S Countermeasures Jidoka Kaizen Kanban Pareto (80/20) charts Process flow charts Poka yoke Pull /Just In Time Manufacturing Single Minute Exchange of Die (SMED) Standard Work Total Productive Maintenance Value stream maps Visual controls Read more…
Just-in-time manufacturing is the method of producing products with only a minimal amount of raw material and component parts on hand. The concept of just-in-time manufacturing is nothing new. Henry Ford saw value in having a minimal amount of stock on hand—a concept which Taiichi Ohno took to heart as Read more…
TPS is the acronym for the Toyota Production System. TPS is more of a business philosophy than a production system, though. It focuses on manufacturing and logistics but doesn’t neglect the human aspect of production. TPS was founded in large part by Taiichi Ohno. TPS can trace its origins back Read more…
The Toyota® Production System began in earnest in post-World War II Japan as a way of managing operations in a challenging economic time. The Toyota Production System really began as a synthesis of Henry Ford’s operations and those of the U.S. supermarket system. Taiichi Ohno, often credited as the founder Read more…
I’m finding myself quickly growing more comfortable in front of a microphone talking about Lean. It helps that I love the topic, and could talk about it for days. This podcast contains my thoughts about where Lean can be useful. The idea came to me while I was at a coffee Read more…
Lean vs. Batch Manufacturing I’m branching out a little, and have been working on some video content for my site. This one is an animated comparison of how products flow through batch and Lean manufacturers. The side-by-side view of both production methods highlights the advantages that Lean offers.
