You have probably already seen this diagram, which summarizes different manufacturing typologies, in one form or another: Is the Demand Driven model a good fit for these typologies? How would your demand driven manufacturing implementation change to support each environment? In each of these flow typologies, with the exception of Engineering-to-Order (ETO), customer demand moves … Read more

intuitive supply chain: brain

What happens in our brain when we exercise our intuition?  A French scientific magazine recently devoted a fascinating dossier to intuition (Science & Vie, August 2021 https://www.science-et-vie.com/archives/n-1247 ). It appears in particular that intuition is the automatic implementation by our brain of knowledge accumulated in our long-term memory. Far from being a random and therefore unreliable process, … Read more

demand driven methodology - team

We are all different… The question is a recurring one. “We manufacture to order, is this relevant to us?” “For the automotive industry, yes, but we are in the aerospace industry, we have many more items!” “We have many constraints, is it compatible?” “It’s for large corporations, isn’t it? We are a SME!” “Okay for … Read more

production schedule - stopwatch

Industry 4.0 and digitalization are on the rise. Technology is moving into our shop floors. LCD touch screens are gradually replacing physical boards and post-its. However, we must recognize that the vast majority of our workshops, however complex, are planned or scheduled in Excel, right? The promise of scheduling algorithms Scheduling solutions have existed for … Read more

chart - DDOM metrics

Hm, seeing the visual illustrating this post I had some objections: is it really reasonable to represent the measures of a supply chain in the 21st century as following a normal law? No, certainly not – the measures do not follow the normal law, while we live more than ever in a new (ab)normality. However, … Read more

flow profile

Flow Profiles vs Inventory Buffer Profiles For DDMRP inventory management, buffer profiles are defined. A buffer profile groups together articles with similar characteristics – replenishment times, demand variability, supply variability. This will allow to assign identical buffer sizing rules to all these articles (red, yellow, green zones, detection of demand spikes, etc.). When it comes to building a … Read more

DDMRP implementation has long been the domain of experimentation, pilots and deployments of limited scope. With a few exceptions, small and medium-sized enterprises, with faster decision-making processes, were the first a few years ago to adopt the methodology, as well as isolated sites of larger companies. Over the past two to three years, a new … Read more

Let’s be zen in the VUCA world. What is Heijunka? In the implementation of a Lean pull flow derived from the Toyota production system, the Heijunka is an essential mechanism whose key role is to level load the flow. Typically, a Heijunka controls the pace and sequence of production on a given flow. As paradoxical … Read more

Four years ago I was invited to introduce DDMRP to a team from a medical device company, a subsidiary of a German group. Supply chain, purchasing, production, quality were in the room. They wanted to know more because they were suffering from long lead times, too much stock, unsatisfactory service levels, and faced many emergencies. The company had … Read more

Pull Flow, an Old Story… 

In 1987, as a young engineer at Philips, I had the chance to take part in a study trip to Japan and visit about ten companies there. In most of them you could see in each workshop card boards. In one of the factories I asked our guide what it was. He was astonished that I asked the question – it was so obvious: it is a Kanban board, to replenish supplies. That is normal. It was a non-event, a practice that was not questionedhad been in place for decades… but almost absent at the time from our western factories. Kanban dates to the ’50s. Drum-buffer-rope dates back to the ’80s. These are old concepts. Are they adapted to our modern, technological age?

When I was a kid I learned to play ping-pong on a homemade table. The boards were not made from one piece, but were made from planks that had been assembled. With time and playing in the garden, the wood had worked, the boards had spread, bent, deformed – it never stopped us from playing hard games, but the bounces were quite unpredictable!

Have you ever watched a relay race? Each runner gives the best of his performance for his portion of the race, and passes the baton to the next runner in a predefined area. In a 4x100m relay, to pass the baton there is a 20m transmission zone: 10m before the 100m, and 10m after. This … Read more
