Improve communication, collaboration, inclusion—virtually all aspects of work that involve interpersonal interactions—with the SDI® assessment.

The Strength Deployment Inventory (SDI) is a proven, research-grounded personality assessment designed to reveal what truly drives people — their motives, strengths, behaviors, and how they respond under stress. Through a digital, easy-to-use platform, SDI provides a comprehensive “map” of how an individual operates when things are going well and how those same motivations may shift during conflict.

Specifically, SDI gives you four complementary perspectives:

  • Motivational Value System (MVS): Your core drivers when you feel at your best — the blend of primary motives (People, Performance, Process) that influence your behavior, decisions and relationships. 

  • Conflict Sequence: How your motives and behaviors shift under stress or pressure, helping predict how you’ll respond and what triggers tension. 

  • Strengths Portrait: A prioritized view of the behaviors and strengths you’re most likely to use at work or in relationships — giving clarity on how you contribute when things are going well. 

  • Overdone Strengths Portrait: Insight into how your strengths may become liabilities when overused — which behaviors, though well-intended, might backfire in certain settings.

SDI Applications
Insights gained from the SDI have many powerful applications for teams and organizations

Team Building

SDI insights help people understand their own and their teammates’ motives and communication styles. These insights contribute to self-awareness and understanding and can lead to more effective communication, collaboration, and conflict resolution.

Leadership Development

The SDI can help leaders identify how they prioritize their strengths and opportunities for growth in communication and conflict resolution—helping leaders better relate with their team and connect people’s intrinsic motives to organizational goals.

Individual Development and

Self-Awareness

The SDI gives individuals a view of their own motives, strengths, and communication preferences. This perspective can increase self-awareness and lead to improved personal and professional relationships.

Conflict Resolution and Mediation

The SDI can help you understand the motives and communication styles of those involved in disputes. You can use these insights to identify the sources of the conflict, resolve it, and reconcile relationships.

Coaching and Performance Management

The SDI can help managers provide more meaningful feedback and coaching. They can use the insights from the SDI to connect performance standards and goals to each person’s motives and strengths.

Curriculum Integration

Organizations can easily add the SDI assessment to any existing training program or learning initiative (i.e. onboarding) to improve the effectiveness and application of learning goals.

Change Management

The SDI insights can help teams more effectively manage large-scale change efforts by strengthening relationships and improving collaboration during disruption and transition.
