The business profession might be called, from the vendor's side, pre-sales, advanced sales or sales. Basically, vendors often have staff to help customers meet their business requirements using the vendor's products. I suspect vendors provide training.
From the customer side, especially when dealing with large/expensive network platforms, your more experienced engineers and/or "network architects" determine the business needs and select equipment. The customer's folk ofter work with vendor's folk in selecting equipment, again, especially for larger/expensive products.
People resources, allocated for these tasks, are often proportional to the cost of the equipment. For example, Cisco won't help you much in selecting and purchasing a single 800 series router. Nor will most businesses have a principal engineer or network architect involved in such a process. However, if you need to buy 10,000 800 series routers, or a CRS-3, both vendors and businesses tend to invest more in people resources to "get-it-right".
