Letter to grandma is a method that plays with the deliberate simplification of explanations of products or basic offers in the context of innovation projects.

The participants are called upon to explain a product as simply as possible so that "grandma would understand it herself". In addition, the method generates the pressure on the user to separate from customer-unintelligible technical terms, from foreign words or nested technical language.
