For instance, when I worked on a project expanding our manufacturing process to Germany, I had to account for the stringent environmental regulations and adjust our waste management protocols accordingly.

Cultural considerations are equally vital. I collaborate with local teams to understand work ethics, communication styles, and any cultural nuances that might impact the process. In one case, I was scaling a process to Japan, where there is a strong emphasis on precision and quality. I incorporated additional quality checks and more detailed documentation to meet these expectations. This approach not only facilitated smoother operations but also built trust and rapport with the local workforce.”
