Keeping new and innovative products in your lineup will help you to succeed. If you are offering the same products that the other manufacturers are or products that are outdated and that nobody wants, you will not get many gems for them even if they are of the highest quality. Therefore, you need to be investing in new products. In the research department, you assign your team one product to research and give them a budget. They can only investigate one product at a time. You will be notified on the end of your turn if they were successful. If unsuccessful, they will continue to work on that product until you tell them otherwise.
