The importance of an Ergonomics investigation before designing or changing a production system
In this article I will explain why it is important to do an Ergonomics Investigation before we design or redesign a production system. Every Ergonomic Investigation I have undertaken has saved my client substantially – either capital investment or increased productivity. Ergonomics is one of the most misused words in the English language. The definition of the discipline of Ergonomic as defined by the International Ergonomics Association (IEA, 2000) is:”Ergonomics is the scientific discipline that deals with understanding the interaction between humans and other elements of a socio-technical system. In this definition, ergonomics is the profession that applies theory, principles, data and design methods to optimize human well-being and the overall performance of a system.” So now you know! The most practical application of this science is improving productivity; however the most common motivation for using an “Ergonomist” by management is to improve safety. One can look at reducing the “lost” production time, thus speeding up the process, or making it easier for people to do their job. It will inevitably be one of these the two first mentioned. Making it safer improves productivity as accidents cause loss in production time. Reducing the chances that operators make mistakes is also a practical application of ergonomics. The usual way I become involved in a project is by management wishing to solve a problem.[AM1] Often they already have an idea how they want it done, but want affirmation before spending the budget. Let me illustrate this by giving you an example of one of my projects that resulted in saving company about 150K. The objective was to increase the production output of two sides- by- side operating presses. One press was filled with product while the other one cycled through its pressing process. The way it was set up using both presses […]
