How-Now-Wow is a prioritisation matrix / idea selection tool, which is often combined with Brainstorming, HMW, Design of Experiments.
It compares and plot ideas on a 2x2 matrix by comparing the idea’s difficulty to implement with its novelty/originality.
Creative teams can generate a lot of ideas. Too many ideas to implement. Categorising ideas according to whether or not they are easy to do, and truly new and innovative can help the team decide where best to focus their effort.
Look at each idea, one by one, asking two key questions.

Place the idea somewhere along the vertical scale, close to zero if easy, or 5 if it would be difficult, or 3 if it is in the middle.
How new, or original is this idea?
The more innovative the idea is, move it further along the horizontal scale.
Finally review the grid to choose what to do next:
