Product design requires creativity, experience and, if you are going to be building the product yourself, a substantial amount of technical know how.
The process of product design starts with the need of a full understanding of the requirements. Requirements gathering is a very distinct skill – sometimes the customer has a great idea, but it takes experience to know how it can be improved, tweaked and slightly changed to make it even better. Very occasionally, it is the job of the product designer to let the customer know that the idea they have just won’t work. again, this ability comes with skill, judgment, and experience and can save the company vast amounts of money!
Product design could be as simple as updating an existing product to make it better, or starting from scratch on a completely novel idea which exists only in someone’s mind. These are often distinct roles and not the same skill set. A good example of product improvement would be Dyson’s bagless vacuum cleaner – a massive improvement on a product that had been around for decades before in the same form.
