Rediscovering the kata way

Rediscovering the kata way

It may be only a matter of time until world-class performance becomes a crowded and hyper-competitive arena from which only the fittest will emerge. The proactive captains of industry who first discover the way of kata will outcompete their competitors, whether down the street or on the other side of the planet. But if everyone is doing that, how can you stand out?

Give ratio-delay a chance

Give ratio-delay a chance

Ratio-delay is an effective tool to determine direct labor productivity for shop floor activities. In the context of manufacturing operations, ratio-delay can determine productivity levels as a baseline that provides focus for new “industrial engineered” improvement initiatives – whether from a lean Six Sigma program or a complex re-engineering project.

Ergonomics in a changing world

Ergonomics in a changing world

Ergonomics can affect technology in a positive way, but this influence is not limited to the design and use of new products and the slew of accessories that might have the word “ergonomics” on the packaging. There are ergonomic implications relating to how people consume and make decisions related to technology, as well as how technology affects processes.

A new way to find bottlenecks

A new way to find bottlenecks

This article uses the inter-departure time data to identify the bottleneck machine in a typical serial line manufacturing system. It describes the inter-departure time to be deterministic, and the mean inter-departure time for each machine is used to describe the behavior of the manufacturing system. Although this approach deals with manufacturing systems that have a serial layout type, it can be used on other layouts.
