If you’re considering introducing behavioural or personality assessments into your workplace, this guide provides a clear comparison of two of the most widely used options, DISC and MBTI, and how each is typically applied in professional settings.
Both tools are used as a form of personality assessment, helping people develop self-understanding, improve working relationships, and support personal and professional development. However, they serve different purposes in practice. MBTI is most often used for reflection and personal insight, while a DISC assessment is more commonly used to improve communication, leadership, and team dynamics in workplace settings.
The sections below explain why.
- DISC focuses on behaviour; MBTI focuses on personality preferences
- DISC is practical for day-to-day workplace communication and management
- MBTI is better suited to reflection and personal insight
- DISC is easier to implement and apply across teams
- Many organisations use DISC for action, and MBTI for insight
The Differences between DISC and the Myers-Briggs Type Indicator (MBTI)
DISC and MBTI are both widely used in leadership development, coaching and HR programs. While they are often compared though, they are designed for different organisational outcomes.
DISC focuses on behavioural styles — how people act and communicate in real situations.
MBTI focuses on personality type — how people prefer to think, make decisions, and process information.
This difference becomes most visible in team dynamics, communication, and working relationships, where each framework is used in very different ways.
What is a DISC Assessment and How it Works
DISC is a behavioural model designed to understand how people act in workplace situations. It focuses on observable behaviour such as communication style, response to pressure, and approach to tasks.
The DISC model originates from William Marston’s behavioural theory and is often used as a structured way to understand behavioural patterns in organisations.
It’s built around four main behavioural styles:
The Dominance D-style is focused on action, outcomes, and decision-making. In workplace settings, they tend to be direct, fast-paced, and comfortable taking control of situations. They are often driven by results and prefer efficiency over extended discussion.
The Influence I-style is outgoing, expressive, and people-focused. They tend to bring energy into group settings and are often strong communicators. They are typically comfortable in collaborative environments and enjoy engaging with others.
The Steadiness S-style is calm, consistent, and supportive. They often prioritise stability and reliable working relationships. In teams, they tend to be steady contributors who value cooperation and predictable environments.
The Compliance C-style is detail-focused, analytical, and structured. They tend to prioritise accuracy and quality, often taking a careful and methodical approach to tasks. They are commonly focused on ensuring standards are met and risks are reduced.
Most people show a blend of styles, typically with one or two more dominant behavioural patterns.
DISC focuses on how behaviour shows up in context rather than fixed traits, which is why it is widely used in workplace settings, leadership development, and team communication.
A DISC assessment helps organisations understand behavioural differences and improve how people work together.
What is the Myers-Briggs Type Indicator (MBTI)?
MBTI is a personality assessment based on Carl Jung’s theory of psychological types, developed by Katharine Cook Briggs and Isabel Briggs Myers.
It categorises individuals into 16 personality types based on preferences across four dichotomies, resulting in structured MBTI types that describe how people prefer to interact with the world.
These include preferences around energy direction, information gathering, decision-making, and structure.
Unlike DISC, MBTI focuses on internal personality preferences rather than observable behavioural styles. It is commonly used for reflection, coaching, and self-understanding in personal development contexts.
How Each Was Developed and How They Assess People
DISC originates from William Marston’s behavioural theory, which explored how individuals respond to environmental pressure. It evolved into a behavioural assessment used widely in organisational and workplace environments.
MBTI was developed from Jung’s theory of psychological types and later structured by Myers and Briggs into a questionnaire-based personality framework.
Both aim to understand people, but they measure different layers:
- DISC measures behavioural response in context
- MBTI measures personality preference patterns
This distinction is important when considering how each is used in workplace settings.
Key Differences Between DISC and MBTI Models
The key differences between DISC and MBTI relate to how each framework is applied in practice.
Behaviour vs personality type – DISC focuses on observable behavioural style and communication style.
MBTI focuses on personality type and internal preferences.
Application in real work vs reflection – DISC is used in live workplace settings such as communication, feedback, and team dynamics.
MBTI is used for reflection, discussion, and personal insight.
Simplicity vs depth – DISC uses four behavioural styles, making it easy to apply in real-time environments.
MBTI uses 16 personality types, offering deeper categorisation but less immediate application.
Strengths and Limitations of DISC in the Workplace and Professional Development
DISC is widely used in professional development because it helps explain behavioural differences in practical workplace environments.
What DISC Does Well
DISC provides a simple behavioural language that helps teams understand how people naturally communicate and interact. It is often used in team building and leadership development to improve communication style and reduce misunderstanding.
It’s commonly used for:
- team building
- leadership development
- improving working relationships
- conflict resolution
- communication improvement across teams
A DISC assessment is particularly useful because it helps organisations quickly interpret behavioural differences in workplace settings without overcomplicating interactions.
Limitations of DISC
DISC does not measure ability, intelligence, or deeper personality traits. It focuses only on behavioural tendencies.
It also does not assess values or motivation, meaning individuals with similar DISC profiles may still perform very differently depending on role, skills, and experience.
Strengths and Limitations of MBTI (Myers-Briggs Type Indicator)
MBTI is widely used in personal and professional development, particularly in coaching and structured learning environments.
What MBTI Does Well
MBTI helps individuals understand their personality type and how they naturally approach decisions and interactions.
It is often used to:
- support self-understanding
- explore personality differences
- guide personal development
- support coaching and structured reflection
- improve awareness of MBTI types within teams
- enhance personal growth conversations in professional development programs
It is particularly useful for understanding differences between introverted types and extroverted types and how they approach workplace situations differently.
Limitations of MBTI
MBTI is less practical in fast-moving workplace environments because it focuses on preference rather than behavioural action.
While it is useful for insight, it often requires interpretation before it can be applied in real workplace situations such as communication or conflict resolution.
What Real Users Experience: Coaches, Managers, and HR
MBTI is less practical in fast-moving workplace environments because it focuses on preference rather than behavioural action.
While it is useful for insight, it often requires interpretation before it can be applied in real workplace situations such as communication or conflict resolution.
Coaches
Coaches tend to separate DISC and MBTI based on the stage of development they are working in.
DISC is used when the focus is on behavioural change and communication in real situations. It helps clients understand how their communication style impacts others in workplace settings and where adjustments can improve outcomes.
It is commonly used for:
- communication challenges
- conflict resolution
- leadership behaviour
- improving working relationships
MBTI is used when the focus shifts toward reflection, identity, and long-term personal development. It helps individuals understand how they naturally process information and interpret situations.
In practice, many coaches use both DISC and MBTI together — DISC for behavioural application, MBTI for insight and self-understanding.
Managers
Managers tend to rely more heavily on DISC because it directly applies to day-to-day workplace behaviour and communication style.
It influences how managers:
- give feedback
- run meetings
- delegate tasks
- handle conflict
- communicate under pressure
DISC helps managers interpret behavioural differences in real time and adjust their communication style depending on the person they are working with. This improves clarity and reduces friction in team dynamics.
MBTI is less commonly used in live management situations and is usually introduced in structured learning or leadership development sessions rather than daily operations.
HR Teams
HR teams often see the clearest difference between DISC and MBTI after organisation-wide implementation of behavioural assessments.
With MBTI, employees tend to focus on their personality type and what it means for them individually. It encourages reflection and discussion but often remains personal in focus.
With DISC, organisations tend to develop a shared behavioural language that influences how teams communicate and work together.
Over time, DISC becomes part of everyday workplace conversations, particularly around communication style, behavioural differences, and team interaction.
MBTI, by contrast, is more likely to remain within structured development programs unless actively reinforced.
Cost and Implementation Differences
There is also a practical difference in cost and ease of implementation between the two tools.
DISC is generally more cost-effective and easier to roll out across an organisation. It requires less interpretation, less facilitation, and can be embedded more quickly into everyday workplace practices. This makes it easier to scale across teams, departments, and larger organisations without significant ongoing support.
MBTI, on the other hand, often involves more structured facilitation to ensure consistent understanding of personality types and results. While the tool itself is widely used, organisations typically invest more time in workshops or guided sessions to help people interpret and apply their MBTI results effectively.
As a result, the difference is not just cost — but ongoing usability. DISC tends to integrate more easily into daily workplace behaviour, whereas MBTI is more commonly used in scheduled development or learning environments.
Which is better for your organisation?
DISC is generally better suited when the goal is to improve day-to-day workplace performance — particularly communication, leadership behaviour, and team dynamics in real operational settings.
Because DISC focuses on observable behaviour, it is easier for managers and teams to apply immediately. It supports practical decision-making in areas such as feedback, delegation, conflict resolution, and collaboration. This is why it is often preferred in organisations where behavioural consistency and communication efficiency are key priorities.
MBTI is better suited when the goal is reflection, self-awareness, and deeper discussion about personality type. It works well in workshops, coaching environments, and structured development programs where there is time to explore differences in thinking and decision-making.
In short:
DISC is more action-oriented and workplace-focused
MBTI is more reflective and insight-focused
Most organisations don’t need to choose one exclusively — they tend to get the most value when DISC is used for practical application and MBTI is used for developmental reflection.
