Abstract:

ISO 9241-11 and ISO 13407 are recognized as important standards related to usability. ISO 9241-11 suggests  that  usability measures should cover: effectiveness (the  ability  of users  to complete tasks using the system, and the quality of the output of those tasks), efficiency  (the level of resource consumed in performing tasks) and users’ satisfaction (subjective perception when using the product,  process or system). Based on these  basic  knowledge  on  usability  concept  the  article describes a proposed methodology  for  the global  assessments of  the ergonomics  interventions  in the  case  of  industrial  system.  The research scenario  consists  in  a survey based on  a developed questionnaire  that  evaluate  the  ergonomics  interventions,  in terms of  usability.In addition, the results of an  experimental  research  demonstrate  the  testing  and  validation  of  the  proposed approach. The method could be seen as an ergonomics continuous improvement one.
