A product is an item given for sale. A product can be a service or an item. It can be physical or in virtual or cyber form. Every product is made at a cost and each is sold at a price. The price that can be charged depends on the market, the quality, the marketing and the segment that is targeted. Each product has a useful life after which it needs replacement and a life cycle after which it has to be re-invented. In FMCG parlance, a brand can be revamped, re-launched or extended to make it more relevant to the segment and times, often keeping the product almost the same.
A product needs to be related: the users must have an immediate use for it. A product requires being functionally able to do what it is supposed to and do it with a good quality.
A product needs to be communicated: Users and potential users must know why they need to use it, what benefits they can derive from it, and what it does difference it does to their lives. Advertising and ‘brand building’ best do this.
A product needs a name: a name that people remember and relate to. A product with a name becomes a brand. It helps it stand out from the clutter of products and names.
