Decision Making Styles InventoryTM (4DMS)

The Four Decision-Making Styles Assessment (4DMSA) is a structured self-diagnostic tool designed to help individuals and teams understand how they approach decision making—both when things are going well and when under stress.


It reveals one’s preferred decision-making patterns and how those styles shift under pressure, providing deep insight into personal tendencies, biases, and group dynamics.


The Four Decision-MakingStyles

  • Seeks to understand the background, implications, and meaning behind a decision before moving to details.

    Gift: Insightful questioning and framing.

    Watch-out: Over-analyzing context before acting.

  • Prioritizes data, logic, and testing assumptions to ensure accuracy.

    Gift: Brings clarity and discipline.

    Watch-out: Can become rigid or overly detailed.

  • Generates possibilities and alternatives, exploring “what could be.”

    Gift: Creativity and vision.

    Watch-out: May drift from facts or skip analysis.

  • Focuses on execution, outcomes, and decisive forward movement.

    Gift: Energy and decisiveness.

    Watch-out: May move too fast or overlook input.


Application in Coaching, Mentoring & Leadership Development

Executive & Leadership Coaching

Helps leaders recognize their default and stress-based decision patterns, increasing emotional intelligence, patience, and balance in decision processes.

Mentoring Relationships

Builds awareness between mentor and mentee of different decision preferences, improving dialogue and feedback exchange.

Team Development

üFacilitates appreciation of diverse styles and ensures that all decision lenses—context, facts, possibilities, and action—are represented in group problem solving.

Organizational Effectiveness

Encourages balanced decision processes that reduce bias (“noise”) and lead to higher-quality, more sustainable outcomes.

When used with teams, the 4DMSA helps create a shared decision-making language
— clarifying when to explore, when to analyze, and when to decide.
