The Crucial Role of Converging Mental Models in Group Decision-Making

Key Insight

Functional buying groups are characterized by converging mental models among stakeholders, indicating a significantly greater overlap in understanding compared to dysfunctional groups. This convergence is vital for individual stakeholders to connect on shared priorities and problems, enabling them to tackle broader challenges and pursue greater opportunities beyond basic desires like saving company money or avoiding risk. Data shows that functional buying groups are, on average, 40 percent more likely to purchase a more ambitious offering.

Encouraging this convergence, especially among diverse customer stakeholders, involves several key actions. These include creating a common language, as exemplified by ensuring IT and marketing understand each other's terminology and challenges. Furthermore, it requires fostering a collective understanding of individual perspectives and goals, ensuring everyone comprehends not only what each stakeholder wants but also 'why' it matters for their function, work, and performance. Clarifying group objectives to work towards a single, agreed-upon business goal, and actively overcoming individual and group biases that hinder higher-order agreement, are also essential.

This process aligns with 'norming,' a concept from behavioral psychology where people learn from one another to establish common ground and collective expectations. At its best, norming is driven by a collaborative exploration of problems, objections, and opportunities, aimed at finding compromise and building upon points of agreement to achieve a view greater than individual ideas. Unlike merely seeking lowest-common-denominator agreement, this form of norming uses shared connections as a starting point to explore further possibilities and expand understanding, enabling customers to escape commodity traps and embrace broader visions.
