HIT stands for Heuristic Ideation Technique.
The critical observation is that new products are often a combination of two (or more) of existing products.
- Choose existing products (not too similar).
- List Characteristics / features that make out the item.
- Create a matrix. For each 2 - feature combination, evaluate the benefits of combining the features.
E.g. Scratch resistant pan + Car paint leads to considering 'scratch resistant car paint'
