The idea behind this idea is to design a production process to stop when an error happens, the focus is on getting machine operators to engage help to ensure that the error is not repeated. The logic is to prevent machined components from being processed further on the production cycle where the errors could be greater. In the UK we tend to allow products to move further on in the production cycle knowing that errors can be rectified on another machining process. Under automation the focus is to try and stop this to make sure the errors are not repeated.


Computer Aided Design - Using computer design software to build up new product designs and test suitability.


Computer Aided Manufacture - Taking the design software a step further and applying the design software to making actually products on CNC machines.


Defective material is material which does not come up to the agreed product standards.


A phrase given to constantly trying to address the shortcomings of a manufacturing process, to express fighting to stop constant fires.


Flexible Manufacturing Systems - Flexible production systems designed to enable the production of a variety of different products.


A phrase used to express, a product going through the production cycle and being fault free without any problems. It is generally expressed with the Deming quality cycle, as well as most processes/tasks in the work place, the perfect ideal for us all to aspire to.


Just In Time manufacture - This is the process of re-designing the supplier-buyer relationships so that the suppliers to your business only supply you with raw materials, sub-components when they are actually required for build. This is opposed to holding vast stocks of material.


Using your employees to bring about continuous improvements, requires training and empowerment. Improvement bought about by Kaizen events, and analyzing problems raised to bring real changes.


A simple visual production tool which if implemented can be used to show different areas of the production cycle, where they are as regards with job priorities, possible work/material shortages, and possible tooling requirements.


The time it takes for a product to go from being a design concept through development, product testing, marketing and final launch onto the market place. For an already established product it would be for the time between a customers initial order and when the manufacturer can ensure delivery via purchasing raw materials, manufacturing the product and delivery.


Work which is seen as not adding real value to a product. Non-value adding work is often classed as being the non-production or support services of a business.


Producing more finished products than you have customer demand. Causes over using of resources which could have been used to produce other products.


Observing all the production processes for any given machine group or products.


Taking preventative measures to stop errors entering the production cycle. Includes the use of components in such a manner as that they must be placed in a certain manner to prevent errors. This method is particularly used in the motor industry where car parts must be placed in a certain sequence.


Single Minute Exchange of Dies - Looking at your production process and observing machines which have high changeover times, the concept is to reduce the non-value added time as much as possible, by implementing measures to reduce set up times.


Total plant maintenance - A structured program for ensuring the maintenance of production machinery.


The tasks which make a product achieve a greater value as it is processed through the production cycle from raw material to finished product.


Activities which do not add any value to products and which must be eliminated as soon as possible.


The term used to describe material currently used in the production process, hence term Work In Progress (WIP).
