Guerrilla usability testing is a quick and informal method of testing a product or service with real users in a natural environment.

Guerrilla usability testing is a type of user testing that is conducted quickly and inexpensively. It is typically used to validate assumptions about a product or service, or to identify potential areas of improvement. Guerrilla usability testing involves recruiting a small number of users, usually from the target audience, and having them complete tasks with the product or service in question. The goal is to observe how users interact with the product and identify any issues they may have. From a Product Management perspective, guerrilla usability testing can be used to quickly validate assumptions about the product or service before investing more time and resources into development. It can also be used to identify areas of improvement that could be addressed in future iterations of the product or service. Additionally, it can provide valuable insights into how users interact with the product or service, which can help inform decisions about design and features.
