Measure the impact of solutions

Measure impact of implemented solutions

In ergonomics, we are talking about avenues for improvement and not solutions. Many data, parameters and variables must be taken into account during the ergonomic diagnosis. This is the reason why iterations are necessary during the implementation of the recommendations to ensure their adaptation to the work activity.
Once the ergonomist has proposed avenues for the company, he can go beyond this process by evaluating what he has implemented, to continue to develop them so that they best meet the needs.
Support and monitoring throughout the project are very important. On the one hand, to adapt the proposed solution as well as possible, and on the other hand to collect data making it possible to observe the benefits and harms of the solutions implemented.

In the context of PAD integration such as exoksletons, it is relevant to assess the impacts of the technology. There are different types of assessments depending on the studies carried out (identification of pain, impact of the solution on the organization, integration of new tools, etc.):

  • Physiological assessment with heart rate monitoring to analyze heart rate or electromyography (EMG) to study muscle activity.
  • Questionnaires, which can be used if one wishes to collect data at the organization with many employees, organization or difficult to access (eg location or confidentiality ...). These questionnaires can recover the opinions of people who do not express through anonymity.
  • Feedback is a spontaneous assessment that can be precise or have the appearance of a discussion. On the same principle as the interview, the ergonomist must conduct it so that the employee is not inhibited and the ergonomist can manage to collect the necessary data or new data. These feedbacks are carried out after a test which allows the company to implement the recommended avenues.

The evaluation carried out will condition the data sought, its quality and quantity. The evaluations may be different depending on the time or the individuals.
For example, within the framework of the evaluation on the implementation of the exoskeleton, the physiological evaluation will help the ergonomist to confirm the relevance of what he was recommending or to exploit new avenues of solutions. Feedback from employees is invaluable, it helps mobilize their knowledge and feelings.
Beyond the benefit for the company, the evaluations are for the ergonomist a support allowing him to acquire experience and to improve his interventions.
