article heading demand driven inventory buffer1compressed

The demand driven approach to inventory buffer sizing is very similar to the Lean approach with two clear differences. The Demand Driven approach flexes inventory buffers according to dynamic demand and it is a multi-echolon approach that takes account of factors such as inventory positioning.

The Lean ethos is that all inventory is evil. "Inventory is one of the 7 wastes so it must be bad!"

Yes it is bad if it is hiding waste such as over-production or under-production. If, on the other hand, an inventory buffer is cost effectively protecting the customer from surges in external demand as well as supply variation and instability then it is adding value.

Car or Food Factory Article Picture1comp

Lean manufacturing was developed using the Toyota Production System. Hence it is instructive for those working in the food & beverage industry to examine how food & beverage manufacturing is different when compared to car manufacturing. We have come up with 7 fundamental differences and would love to hear from you if you can think of more.

Article Heading Contracts for complex projectscomp

The project is signed and it's big and complicated!

You're not responsible for the total business outcome but the project sponsor has made it clear that you are responsible for Scope, Cost and Time (ie. until she says otherwise!). So what do you do with that?

Vaguely you know that you should be thinking about how you're going to set up your team so that it suits the style of project you're doing. But you're not sure how that really translates to the type of contracts you use, what sort of purchasing strategy you should use, how you set up your team, the list goes on.

In this article we examine the different configurations of contracts and in-house management resources that are needed for the different levels of project complexity.

Article Heading 4 Factory Disastercomp

You know the signs, the factory keeps missing production schedules and you keep depleting finished goods inventory. Its now so bad that you are missing vital customer orders and some customers are threatening to delist.

This is a common story and here we use a scenario based on actual events to illustrate how an understanding of Flow Consoles and buffers can be used to fix the problem. Details have been changed to protect client confidentiality.

Headline Picure 2 Supply chain post lean and six sigmacomp

Taiichi Ohno is the long accepted Japanese initiator of the western version of the Toyota Production System called Lean. There is growing recognition that his initial ideas, while powerful in an isolated context, were only a portion of his systemic view of a complex supply chain.

In any case, history can now chronicle the rise of his ideas in the west, all packaged in a compelling narrative and condensed down to tools that can be easily conveyed to front-line workers ..... a dream for consulting businesses.

But, in our quest to keep things simple and packaged, have we lost some of the foundational information that made these ideas work in the first place?

This is a tough question and if someone can provide a commonsense answer then they must know what they are talking about. Well here we go!

Heading Picture Stock Aggregationcomp

Production variability and  demand variability causes congestion in supply chains. One way to reduce this congestion is to reduce the variability by addressing its causes.

Another and more subtle way to deal with congestion is by combining multiple sources of variability. This is known as variability pooling, and has a number of supply chain applications. There are two types of Variability Pooling; Queue Sharing and Stock Aggregation and in this article we explore the concept of Stock Aggregation.

Heading Picure Queue Sharingcomp

Production variability and demand variability causes congestion in supply chains. One way to reduce this congestion is to reduce the variability by addressing its causes.

Another and more subtle, way to deal with congestion effects is by combining multiple sources of variability. This is known as variability pooling, and has a number of manufacturing and supply chain applications. There are two types of Variability Pooling; Queue Sharing and Stock Aggregation and in this article we explore the concept of Queue Sharing.

Heading Picure Flow Linescomp

Capacity decisions have a strategic effect on the competitiveness of a manufacturing operation. Flow Lines are commonly used in the food manufacturing and continuous processing industry. In this article we discuss the capacity and system control benefits of un-balancing a flow line, i.e. adding extra capacity upstream and downstream of a flow line's bottleneck.
