Innovation process
Some marketers use a nine-box grid for a more sophisticated analysis. This adds "modified" products between existing and new ones (for example, a different flavor of your existing pasta sauce rather than launching a soup), and "expanded" markets between existing and new ones (for example, opening another store in a nearby town, rather than going into online sales).
This is useful as it shows the difference between product extension and true product development, and also between market expansion and venturing into genuinely new markets (see Figure 3). However, be careful of the three "options" in grey, as they involve trying to do two things at once without the one benefit of a true diversification strategy (escaping a downturn in one product market).
No ideas? Here is a very interesting link, to “Farm Business Innovation 2014” (inspiring rural entrepreneurs), where you can find videos of UK innovative farmers telling their case history.
