Cognitive ergonomics is especially important in the
design of complex, high-tech, automated systems such
as semiconductor-manufacturing lines. A poorly designed
machine user interface may well cause great frustration on the part of workers and result in decreased
production, quality, or even a life-threatening
accident. Some examples in cognitive ergonomics include
interventions such as redesigning manual work
(raising the metal bench, introducing FCB) and applying
PPE, such as earplugs, and installing machine
insulator covers. Other interventions include educating
workers and managers on workplace safety to ensure
conformity of work system designs with Malaysia’s
Factories and Machinery Act and Regulations (2001).
Lot travelers with different colors help the workers to
differentiate the assembly lines. The yellow papers for
LPL and blue papers for CL make it easy for workers to
differentiate where the the products are produced. It is
especially useful in the electroplating process because
both of the manufacturing lines sharing the electroplating
machines. As development of these cognitive
ergonomic processes continues, workers develop and
learn and they grow accustomed to receiving different
types of information in particular formats. It is important
to find out where the information does not
conform to its customary format—where it may be
difficult to follow or to understand by the workers.
