Or should these functions be as close to … Read more

pull manufacturing

Most companies are experiencing difficult times on the supply side. Containers are piling up on one side of the globe and are sorely lacking on the other. Delays are piling up, and variability is clearly at a maximum on the supply side. Can our supply chains really be demand driven in this context? Does pull … Read more

warning symbol - supply chain efficiency

Every planner today has hundreds or even thousands of references to manage. Often, these references must be synchronized during the assembly of products with complex bills of materials, where the slightest shortfall stops the flow. If you manufacture an electronic assembly with hundreds of components, a simple diode that costs nothing can stop everything. How … Read more

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

An artificial intelligence motherboard

Adaptive forecasting. Driverless trucks. Autonomous planning. AI is coming for your supply chain. Right? In many ways, industry watchers can be forgiven for having a little skepticism when it comes to AI in supply chain. According to research by Deloitte, only 40% of supply chain executives said they are actively using AI. The 2021 MHI Annual Industry Report put that figure … Read more

Submarine under water

What is the relationship between submarines and the global supply chain? Don’t worry, it doesn’t have to do with underwater container ships, and Elon Musk hasn’t floated the idea of a silk road via an underwater Hyperloop. Well, not yet, I guess. But what is it about? We have recently seen in the press the … Read more

Industry watchers have warned about dangers that range from natural disasters to trade disputes.  And then, in 2020, the Covid-19 pandemic gave … 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

product launch ddmrp - hands and rocket

Orchestrating the launch of new products is one of the processes you need to define when designing your Demand Driven model. It uses special techniques for several reasons: Since this is a new product, you have no historical demand The uncertainty on the demand profile is greater than for a mature product There can be … Read more

Every time I visit a factory, I ask myself the following questions: Do we see the flows? Does material visibly flow? What are the process steps that set the tempo? Do we see this tempo? Are we early or late? How do we see it? What should be manufactured after the current batch? What are … Read more
