Prioritize Jobs for Improvement
• The frequency and severity of the risk factors you have identified that may lead to injuries
• The frequency and severity of complaints, symptoms,
and/or injuries
• Technical and financial resources at your disposal
• Ideas of workers for making improvements
• Difficulty in implementing various improvements • Timeframe for making improvements
![Page 19: Upper Extremity Musculoskeletal Disorders Recognition and Control](https://reader035.vdocument.in/reader035/viewer/2022062309/56649ec05503460f94bcada7/html5/thumbnails/19.jpg)
Questions for selecting improvement options:
o Reduce or eliminate most or all of the identified risk factors?
o Add any new risk factors that have not been previously
identified?
o Be affordable for our organization (e.g., is there a simpler, less
expensive alternative that could be equally effective)?
o Affect productivity, efficiency, or product quality?
o Provide a temporary or permanent “fix”?
o Be accepted by employees…will it affect employee morale?
o Be able to be fully implemented (including training) in a
reasonable amount of time?
Make Improvements

Follow Up
Questions for evaluating improvements:
o Reduced or eliminated fatigue, discomfort, symptoms, and/or
injuries?
o Been accepted by workers?
o Reduced or eliminated most or all of the risk factors?
o Caused any new risk factors, hazards, or other problems?
o Caused a decrease in productivity and efficiency?
o Caused a decrease in product and service quality?
o Been supported with the training needed to make it effective?
