Description
Three Diverse Humans, or TDH, is a User Story and Design validation technique that involves review and input for three separate, but equal, individuals prior to Product Backlog generation, or commitment to a complex design. The typical TDH session is a one-hour, rapid fire meeting that includes a developer, an analyst/SME, and a tester, but it can be attended by alternative roles as well.

- 1.
The TDH session begins with an agreement of the backlog stories or design to be reviewed.

Five minutes of discussion, led by the author of the work product.

Feedback by non-author participants from their perspective. For example, a tester might provide feedback of additional tools, environments, or technology that is required, while a developer may offer suggestions for downsizing a story.

The User Story or Design is adjusted in real time, if possible, or placed on the backlog for a design sprint, spike, or backlog grooming session.
