Which has a somewhat different feel to its existing product, which has a totally different look.
On the product lifecycle nougat is surely a mature product and the photo above shows a classic existing product in existing market.
Race Food is a normal nougat modified to be less sweet and softer to chew and of course packaged in a size and format that suits the athlete. So it's an existing product entering a new market, hoping to start a new growth phase in Wedgewood Nougat lifecycle. It's also interesting to note that according to Wedgewood the idea came from their customers.
After some time and success in the market this might become material for a business school case study.
