Product design services are something which are accessible to everyone, but there are distinct advantages that large companies have over smaller ones. The budget, by and large, is far above what a smaller company could possibly invest, so the amount of work that can go into the design of a product is comparably larger.

So, while both of them have an effort undertaken by design specialists; where any consultant in the business would produce a number of designs and then go with the one the client likes best, a product design which has a large development budget will be able to create a massive number of design alternatives, 3D prototypes of each of them,  organise focus groups, and focus on the details like the ergonomics. Being able to do all of this stuff provides a clear dividing line between what smaller companies can achieve with their product launches and what larger companies can do.
