Nowadays, ergonomics has been implementing new methodologies to be applied in different areas and stations, whether in a work, productive or common area. It is in this context that ergonomics has a great impact within the different organizations to maintain the maximum possible productivity. That is why the main objective of this research work is to carry out an ergonomic analysis, using RULA and REBA techniques, throughout the process and to identify possible ergonomic problems in a bakery business. To carry out this analysis, we first conducted a systematic literature review to enter into the context of how ergonomics applied in organizations has evolved. With the context clear, we applied the two techniques with the support of the Ergonautas website, which can provide us with warnings of the ergonomic level of the activities and take immediate actions. With this analysis, we will be able to identify the activity that can harm the physical health of the operators. Once the entire station was analyzed, we recorded the data in Ergonautas to obtain the risk level score of the activities, both for the REBA and RULA techniques. With the data recorded in the system, we obtained that there are three activities within the production process that threaten the physical health of the workers, which are mixing, cutting and baking. With the results, a 3D improvement proposal was made in Autodesk Inventor in the three activities to reduce the level of ergonomic risk and not to continue harming the operators. Finally, the results obtained in the research were discussed. A comparison of our results with those of other investigations was made and we reflected on the importance of applying different techniques to obtain more significant results when considering the level of urgency to improve an activity.
