DISC v Myers-Briggs v Enneagram: Which Test Is Best for Your Organization?

Personality testing has become a standard line item in team building and career development budgets, and with that comes an important decision: which assessment is the organization going to invest in, roll out, and use?

That decision carries significant weight. Personality test adoption is extremely high among large US enterprises. More than 80% of Fortune 500s use them to manage team dynamics and improve communication, and at least three in every ten executives sat tests when they were last recruited. For some, that process would have included a combination of tools covering everything from their work ethic and EQ to their approach to team-building, attention to detail, and the speed with which they make decisions. 

No single personality test can cover all of these aspects completely, because popular tools like DISC, Myers-Briggs and the Enneagram were built to measure different things. The choice depends on: 

• What the organization is trying to accomplish.
• Ease of use and the test-taker’s experience.
• The quality and compliance of the test, because the model you choose often matters less than the rigor behind it.

Let’s look at each in turn.

DISC v Myers-Briggs v Enneagram: What Are They Measuring?

Both DISC and Myers Briggs (including TypeFinder®, Truity’s 16-type model it inspired), are extremely popular workplace tools. They have been used for decades at an international scope. The Enneagram is a more recent addition to the workplace. Once regarded as too personal and intrusive for a professional setting, it has moved from the fringes of self-help into structured use by companies including Google and Facebook, which have brought the Enneagram to their workforce because of the results they see in the areas of communication skills, conflict resolution, personal growth and emotional intelligence.

Each test approaches personality from a different angle, and the distinctions matter when deciding which one suits your organization's goals:

DISC, Best for Day-to-Day Teamwork

DISC measures observable behavior across four personality dimensions – Drive, Influence, Support and Clarity – though some tools, including Truity’s, also identify blended types where the four primary styles overlap. DISC focuses on how people communicate and act in the workplace, which makes it a practical tool for improving team dynamics. Organizations use it to:

• Understand the workstyle, strengths and blind spots of each team member.
• Allocate roles and responsibilities on teams.
• Set performance goals.
• Bridge communication gaps.
• Structure meetings that work for everyone.
• Integrate new team members.
• Resolve conflict.
• Assess an individual's leadership style ahead of development.
• Support specific use cases like sales training.

Myers-Briggs, Best for Decision-making and Problem-solving Insights

Myers-Briggs sorts individuals into one of 16 personality types based on four core preferences, covering how people direct their energy (Introversion v Extraversion), take in information (Sensing v Intuition), make decisions (Thinking v Feeling) and structure their working lives (Judging v Perceiving). It focuses on underlying cognitive preferences rather than day-to-day behaviour, which makes it a useful tool for conversations about problem-solving style, how people communicate and how they process change. Because the 16-types model touches on decision-making and information processing, it tends to land well in contexts like team-building and strategic planning, where understanding how people think matters as much as how they act. Organizations use it to:

• Understand how team members prefer to process information and make decisions.
• Match individuals to roles that suit their natural strengths.
• Improve communication between different working styles.
• Support long-term career development conversations.
• Build self-awareness as part of leadership training.
• Reduce friction in cross-functional teams.
• Structure onboarding around how new starters prefer to work.
• Identify potential blind spots in decision-making styles.

Enneagram, Best for Motivation and Mindset

The Enneagram describes nine core types, each organized around a central motivation, a core fear, and a pattern of behavior that emerges when a person is under stress or feeling secure. Unlike DISC and Myers-Briggs, the Enneagram leans heavily into the why behind people’s actions, and is the most introspective of the three systems. Teams tend to reach for it when they want to understand underlying values, recurring conflict triggers, or what genuinely motivates someone to do their best work. It is especially helpful for:

• Understanding what motivates each team member beyond their observable behavior.
• Supporting personal growth and self-awareness at work.
• Improving conflict resolution by addressing root causes.
• Building emotional intelligence across a team.
• Coaching individuals through stress and growth patterns.
• Deepening leadership development beyond surface-level skills.
• Strengthening trust and psychological safety in teams.
• Supporting long-term culture-building work.

It’s worth noting that all of these tests are designed to provide guidance and do not suit the recruiting process. Personality is always complex, and the results of an assessment cannot bring enough information to justify a hiring decision on their own. A personality test score says nothing about someone's skills, experience or ability to do the job, and treating it as a shortcut risks overlooking candidates who would otherwise be a strong fit. 

How Easy is It to Administer and Apply the Tool?

A personality assessment is a tool supporting strategic targets, and its value depends on what happens after the results come in. A report that sits in an inbox delivers nothing. The insight has to be applied through structured follow-up, whether that's a team-building workshop, a coaching session or a set of team norms built from the results, before it can justify the investment.

Not every organization has someone in-house with personality expertise to guide the team, and that changes which model makes sense as a starting point: 

• DISC's four styles are the easiest entry point for a team coming in cold. The framework is quick to understand and quick to explain since the results map directly onto observable workplace behavior.
• Myers-Briggs asks more of a facilitator. Sixteen types naturally carry more nuance, and the team will benefit from someone who can talk knowledgeably about the preferences behind each letter. 
• Enneagram demands the most from whoever is running the rollout, given how closely its interpretation depends on understanding fears and motivations. Staff may question the science or feel unsafe, and a host may need significantly more preparation time in order to answer deep or skeptical questions. 

That said, none of this makes one system harder to justify than another – it simply means the time investment should scale with the depth of the model chosen. Your choice of vendor matters here as well. A test provider who offers only a report leaves the interpretation work to internal teams who may not have the time or training to do it well. Choosing a vendor like Truity, who supports the rollout through training materials, facilitator guides and ongoing access to coaching resources, gives the organization a far better chance of applying the results properly, even without dedicated personality expertise on staff. 

On the test-taker side, the user experience should also be taken into account. The more user-friendly and intuitive the testing platform is for team members, the easier it will be for anyone to take the test. Your buy-in should be greater as a result. 

And of course, team members must be able to understand the results! It's worth requesting a sample report before committing to a test provider. A good report should be legible at a glance, free of jargon, and clearly mapped onto workplace situations. The Enneagram in particular tends to be the hardest of the three for people to grasp quickly, since its results describe invisible core motivations rather than surface actions, and it requires confronting unconscious psychological blind spots. That isn't a mark against the model. It simply means a well-written report carries more weight, since it's doing the work of translating something abstract into language a team member can recognize and use. 

The Statistical Foundations of Each System

Any personality inventory, be it DISC, Myers-Briggs or Enneagram, should measure the traits of personality scientifically and produce similar results for the same person over time. It should hold up against real behavior on the ground.  We therefore recommend using a personality framework based on solid statistical research. Don’t be afraid to ask the vendor for evidence of the test's reliability and a breakdown of their validity research.

Of the three tests in question, the Enneagram historically has had the biggest question mark over its scientific grounding. The system originated from philosophical and spiritual traditions rather than psychological research, and for decades it lacked the peer-reviewed studies that would let researchers verify its reliability or test its structure against established models of personality.

That gap has since narrowed significantly. Truity’s Enneagram for the Workplace assessment is one of only a handful of scientifically validated Enneagram tests built specifically for teams, leaders and organizations. It has been extensively researched and validated using a large global sample of over 2.3 million users, with the assessment shown to have excellent reliability by standard psychometric measures, and the nine types shown to correlate meaningfully with real workplace behavior. 

For managers, that means the results can be used with the same confidence as DISC and Myers-Briggs, which have accumulated decades of academic study and have a long track record to draw on. 

That depth of research doesn't guarantee a better fit for every team. But it does mean the statistical case for all models is well established and ready to withstand scrutiny. 

So Which is Best: DISC, Myers-Briggs or Enneagram?

There's no single right answer to this question, because the three tests were built to measure different things. What matters as much as the model itself is partnering with a vendor who makes testing easy to administer, backs the assessment with solid scientific research, and provides the training resources needed to apply the results well. Once that foundation is in place, the choice comes down to the outcome the organization wants: 

• CHOOSE DISC if the priority is understanding day-to-day workplace behavior, allocating roles, and building practical communication and feedback habits across a team.
• CHOOSE MYERS BRIGGS if the priority is understanding how people think, process information and make decisions, particularly for career development and long-term team building and productivity.
• CHOOSE THE ENNEAGRAM if the priority is understanding what motivates people at a deeper level, strengthening trust and psychological safety within a team, and supporting personal growth, especially if it’s the natural next step for a team that already has DISC or Myers-Briggs behind it. 

Many organizations end up using more than one framework over time, starting with DISC for quick wins and layering other models as the team matures.
