Pretty much all companies are based on a hierarchical structure. One superior manages multiple subordinates. The question is: How many subordinates should be managed by a superior? This is also called the span of control. This depends on a number of factors. Let’s have a look at efficient group sizing.

Diseconomies of Scale
Production Sequences: FCFS, EDD, and Others
Delivery Sequences: FIFO, LIFO, and Others
Sometimes, when you need a part or product from your inventory, you may have more than one item in stock. Which one do you pick? In this blog post I want to present a few strategies for choosing which item to take. The most famous one is FIFO, but there are more options available. In my next post I will present similar strategies if you need to start production before the item becomes available.
Hoshin Kanri – Part 4: The X-Matrix?
When googling Hoshin Kanri, you will sooner or later come across an X-Matrix. It is a visually very impressive tool, but I am in serious doubt about its usefulness. It focuses on the creation of the Hoshin items, but to me this approach is overkill, and – even worse – may distract the user from actually following the PDCA, especially the Check and Act parts. While the article is highly critical, I hope reading it and understanding the shortcomings help you better understand how Toyota thinks.
Hoshin Kanri – Part 3: Hierarchical Hoshins
Hoshin Kanri can be used individually, but its full potential is shown across the levels of corporate hierarchy. The goals of a Hoshin Kanri should be derived from the Hoshin Kanri of the next-level hierarchy above. This post is part of a larger series on Hoshin Kanri. Let’s look at the hierarchy structure:
Hoshin Kanri – Part 2: PDCA
Hoshin Kanri – Part 1: The To-Do List
This week I will look at Hoshin Kanri (方針管理, policy management). The word is often used as a sort of miracle cure for the problems in your organization. The tool itself, however, is rather mundane, although it did significantly help Toyota. This, of course, did not stop the West from over-complicating and over-hyping it. This post is the start of a small series on Hoshin Kanri.
