How Does Small And Medium Scale Enterprises Contribute To The Development Of An Economy?

Well, just for fun the company i worked for built scales(actual weighing  devices) for weighing barrels used in printing companies and paint companies and plastics manufacturing companies....then the medium size scales we built were used in weighing crates for the shipping industry and even used at race tracks for weighing the race cars....i even built a custom scale in the medium use design for a paper mill to weigh their rolls of paper....then  the large scales we built were used for the weighing of semi tractor trailers hauling everything from produce to building supplies...we even had scales used to weigh train cars/hoppers for loads of coal and grain for granaries to produce cereals and bread....so our medium sized company impacted other companies abilities to process their products/ingredients for use in their products...i even built custom cattle scales for farmers to maintain healthy livestock for consumption by the populous...so i guess you could say our medium sized company impacted just about every other company in business in the surrounding areas..is this what you were looking for...
