What is the biggest expense in product development?
The biggest expense should be in marketing the product, not developing it, because marketing should remain on-going. If it is not, then the vitals of the product may be in poor health. Sometimes, marketing can cost only time, rather than dollars. But a good marketing plan is definitely as important as the technical skills that CSE can offer you! Sometimes adding technical features to a product is mere marketing efforts in disguise. Build your prototypes, run you press releases, go to the trade shows and get them out there to build sales!
