A mental model diagram is a fishbone or horizon diagram where the top towers represent individuals’ motivations, emotions, and stories related to their experience in achieving a particular goal, regardless of the tools they use. The top part of the diagram is person-focused, not solution-focused. The bottom towers of the diagram represent the features of your organization’s offerings, aligned beneath the appropriate upper towers that they support the best. You can see where your organization’s design and business requirements support people’s goals well and where they need improvement. The diagram as a whole is generative, not evaluative, helping your organization realize weaknesses and gaps in the way you support people and adapt existing products, services, or processes to particular behavioural audiences or situations.
