Supply Chain View

A lengthy post today that’s been in the pipeline for a while. The Lean Enterprise Institute have published an English translation of The Birth of Lean, recounting the experiences of the early Toyota practitioners, and how their experiences shaped what became Lean methods and thinking. The introduction and first chapter are available as a free [...]

Sometimes people tell me that 5S only applies in factories, and if they’ve been exposed to the “inactive banana” school of dim-witted implementation I can’t blame them. But here’s a cautionary tale that might persuade you that the principles – intelligently applied – are sound. Supply Chain View has been “off air” for a while [...]

Sometimes people get hung up on semantics. Sometimes it pays to be clear – very clear. I am currently trying to wade through some waters muddied by misunderstanding and poor use of terminology. My employer has had some good quality experience of Lean (albeit in a fairly small section of its operations) for about four [...]

This is a question that arises with frightening regularity. Although we generally want both availability and stock turn to continue improving over the long term (and there are various methods of achieving that), nonetheless there are some theoretical limits to those numbers, together with a requirement to decide the availability target for right now. Let’s [...]

You wouldn’t expect a great lesson in Six Sigma from an alcoholic Beat novelist, would you…? This is from Charles Bukowski‘s first novel, Post Office, which is a semi-autobiographical account of the author’s “career” with the US Postal Service, delivering and sorting mail. I’ve mainly paraphrased the episode in order to respect the author’s copyright. [...]

I have had a couple of conversations recently that have led me to think about how much overstock we might expect in a Pull supply chain even under fairly idealistic conditions. The first was with a colleague working on a redesign of a warehouse in which a large number of products had stock outside of [...]

The BBC reported last week that UK online retailing grew by 33.4% to £10.9bn last year. Today the headline was that supermarket Kwik Save was closing 79 stores in a bid to stay afloat. The former story is a well attested trend, and putting it next to the latter is to make a point in [...]

At a seminar I ran earlier this week for CILT, this is a paraphrasing of what one of the delegates said to me: “Lean is all about cost reduction. It focuses on the internal processes of the company. It does not think about the customer.” It is now over 60 years since Toyoda Kiichiro, then [...]

Is there a developing backlash against Six Sigma? Scott Adams published a Dilbert strip in November last year with the punchline “Why don’t we jump on a fad that hasn’t already been widely discredited?” (Dilbert strips are now available online for only one month, but Gemba Panta Rei provide a full transcript in a post [...]

I was interested to find an article in this month’s Logistics & Transport Focus headed “No more lean times: why inventory is not waste and warehouses add value”. The author, Steve Sordy, has chosen a title that is a kind of teasing of the more dogmatic of lean devotees – British culture has little patience [...]
