Product design is only one key to brand success but it is very important. Consumers must find the design of the product desirable and useful but other factors play a role in the success of the product. Advertising is also key in getting the word out about your product especially if the product is a new one recently introduced to the marketplace. Your company may have produced the best gizmo ever but if no one knows of its existence it doesn't matter that the product is good. Effective marketing of your product line is essential for your success.
