The Thomas-Kilmann Conflict Mode Instrument measures 5 conflict resolution styles. DISC measures observable workplace behavior (4 styles). Both are workplace-focused but answer different questions: DISC describes how you act day-to-day; Conflict Styles describes what you do specifically when in conflict. Used together in team training. Both are free on JobCannon.
Both the Thomas-Kilmann Conflict Mode Instrument and DISC are widely used in organizational development, but they measure fundamentally different aspects of workplace personality. Conflict Styles focuses specifically on HOW you handle disagreements and disputes, while DISC describes your overall approach to work, communication, and interpersonal relationships day-to-day.
If you’re building team resilience, conflict resolution training is incomplete without understanding individual conflict preferences. If you’re improving general team dynamics and communication flow, DISC provides the foundation. The two assessments complement each other perfectly—one reveals behavior under pressure, the other reveals behavior under normal operations.
This guide breaks down the key differences between these two frameworks so your team can choose the right assessment for your goals. Many organizations find that taking both tests provides a complete picture of how their teams interact, especially when conflict resolution and team development are top priorities.

Developed by Kenneth W. Thomas and Ralph H. Kilmann in 1974, the Thomas-Kilmann Conflict Mode Instrument was built on the Blake and Mouton Managerial Grid, a foundational framework for understanding interpersonal behavior. The instrument measures five distinct modes that describe how people respond when their concerns conflict with the concerns of others. These modes—Competing, Collaborating, Compromising, Avoiding, and Accommodating—reflect different combinations of assertiveness and cooperativeness.
The Thomas-Kilmann framework has become the gold standard in conflict resolution training, organizational development, and team mediation. It is widely used by HR professionals, team coaches, and conflict resolution practitioners because it helps people understand their natural conflict tendencies and learn to flex their approach depending on the situation. Unlike personality models that describe who you are, Conflict Styles describes how you respond under pressure.
DISC theory originates from William Moulton Marston’s 1928 book "The Emotions of Normal People," which proposed that human behavior can be understood through two primary axes: how someone responds to their environment and whether they are people-oriented or task-oriented. Modern DISC instruments, particularly those operationalized by Inscape and Wiley, classify people into four styles: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). These styles describe your natural preferences in communication, decision-making, and how you interact with others.
DISC has become one of the most widely used personality frameworks in corporate training, team building, and sales training globally. Millions of people have completed DISC assessments, making it a common language in many organizations. DISC is particularly valuable because it describes not just conflict behavior, but your overall behavior patterns, motivations, and communication preferences across all workplace situations—not just when disputes arise.
Conflict Styles applies specifically when you face disagreement or competing interests. It answers the question: "How do I handle this dispute?" DISC, by contrast, describes your everyday behavior and communication style regardless of conflict. It answers: "How do I naturally interact with others?" A high-D DISC person might avoid conflict most of the time, but when they do face conflict, they may compete strongly. A high-S person might naturally be steady and accommodating both daily AND in conflict.
Conflict Styles offers five distinct modes because conflict specifically involves trade-offs between assertiveness (pushing your agenda) and cooperativeness (helping others). DISC uses four styles because it measures broader personality dimensions—how fast you move, whether you focus on people or tasks, and your natural comfort with risk and uncertainty. Five modes work for conflict; four styles work for personality. Neither is "better"—they’re designed for different purposes.
Conflict Styles emerged from decades of organizational research on conflict resolution in the 1970s. DISC is rooted in 1920s psychology theory, making it one of the oldest personality frameworks still in widespread use. Both have stood the test of time and been validated across thousands of studies, but Conflict Styles is specifically engineered for conflict resolution, while DISC is engineered for general personality and team dynamics.
If your organization is serious about team development, conflict resolution, and communication excellence, both assessments are worth taking. Conflict Styles reveals how each team member approaches pressure and disagreement—critical information for resolving disputes. DISC reveals how team members naturally interact, communicate, and make decisions—the foundation for strong daily collaboration. Together, they give you a 360-degree view of your team’s strengths and opportunities. On JobCannon, both tests are free and take about 15 minutes each. Use them to build teams that communicate well every day AND handle conflict with skill and respect.
