In an interview of Patrick Larvie I heard the term “Bollywood Method”, I googled for it and following is my understanding.
When participants hesitate to give their honest opinion about design, when they avoid criticizing the design, we can build a story like bollywood film and ask the participants to act in that story as per the storyline. Plots require participants to use the product to move the story further. Now users are using the product as some characters in the story and thus they don’t feel offended to share their honest opinion about the product.
