Using personality insights to strengthen team performance

What if the key to your team's best performance isn't a new process or a fresh strategy – what if it's understanding who they actually are? 

Using personality insights for team performance are transforming how forward-thinking HR leaders approach coaching and team development. When people understand themselves and each other, everything improves: communication, collaboration, conflict resolution, and performance. And when you combine that self-awareness with AI-powered coaching, the impact multiplies.

This blog post walks through the core personality profiles that matter in the workplace, why they're commercially important, and how combining profiling with smart technology helps managers become great leaders.

How you can use personality insights for team performance

Personality profiling uses structured frameworks to identify how people naturally think, communicate, and make decisions. One of the most widely used is the Myers-Briggs Type Indicator (MBTI) – based on Carl Jung's work and developed by Isabel Myers and Katharine Briggs.

MBTI isn't a test. There are no right or wrong answers, and no “good” or “bad” personality types. It identifies natural preferences across four dimensions:

• Extraversion vs Introversion – how people recharge their energy

• Sensing vs Intuition – how they take in and process information

• Thinking vs Feeling – how they make decisions

• Judging vs Perceiving – how they structure their outer world 

   

The result is a four-letter type (e.g. ENFP, ISTJ) that offers a window into how someone works best – not a box to put them in. 

Important: MBTI should never be used to make hiring or performance-based decisions. It's a development tool, not an assessment of ability or intelligence. This aligns with CIPD guidance on performance management – personality tools are development instruments, not assessment ones. 

The four dimensions of personality profiling: a practical overview

1. Extraversion vs Introversion
   Extraverts are energised by interaction – they think out loud, jump in, and learn by doing. Introverts recharge through reflection – they process internally and often perform best when given time to think before a meeting or conversation. 

   Practical tip: before a difficult conversation with an introvert, share notes or an agenda. Give them time to digest the information in advance rather than putting them on the spot. 

2. Sensing vs Intuition

   Sensors focus on facts, details, and what's real right now. Intuitives look at the big picture, patterns, and future possibilities. 

   Practical tip: When presenting a new initiative, sensors want the practical specifics first. Intuitives want to understand the vision and why it matters.  

3. Thinking vs Feeling

   Thinkers make decisions based on logic, data, and objective analysis. Feelers weigh up personal circumstances, values, and the impact on people. 

   Practical tip: neither approach is better. The most robust decisions often come from combining both lenses – which is a strong argument for diverse teams. 

4. Judging vs Perceiving 

Judgers like structure, plans, and closure. Perceivers prefer flexibility, spontaneity, and keeping options open. 

Practical tip: sudden changes to plans are more stressful for strong Judgers. Flag them early, with context, and give them time to adjust.

Here's the honest truth: most managers know their team members' job titles and role responsibilities. Far fewer understand what actually drives their behaviour.

When someone misses a deadline, is it laziness – or are they a strong Perceiver who struggles with rigid structures? When a colleague is quiet in meetings, are they disengaged – or are they an Introvert who needs time to reflect before speaking?

Without this context, managers default to assumptions. With it, they adapt.

At an individual level, personality insights help people: 

• Build emotional intelligence and self-awareness

• Understand their stress triggers

• Identify development plans that genuinely suit them 

At a team level, they help: 

• Build trust faster and more authentically

• Reduce conflict by understanding what drives different behaviours

• Improve decision-making by making space for all voices – especially introverts

At a business level, the impact is commercial. Personality awareness boosts engagement, well-being, and retention. People who feel seen and able to be their authentic selves at work are less likely to leave. And leaders who understand their team's preferences can manage change more effectively, reducing the friction.

Understanding personality insights for team performance starts with knowing what actually drives your people's behaviour. For a deeper look at how to put these insights into practice, read our guide: How to use personality insights to build high-performing teams.

What happens when you combine profiling with AI coaching?

Understanding personality types is valuable. But applying that understanding in real-time conversations – now that's where the real magic happens.

AI-powered coaching tools like MyTeamBuilder bridge this gap. MyTeamBuilder (MTB) is a psychometric and team performance platform that profiles individuals using personality assessments, then gives managers access to an AI coach (Billee) that can:

• Prepare you for specific conversations based on the other person's personality type

• Suggest how to adapt your communication style in the moment

• Help you navigate conflict with calm, impartial guidance

• Surface team-wide personality distribution so you can spot strengths, gaps, and risks at a glance 

MTB in action: our tech team

When we rolled out MyTeamBuilder internally, the team dashboard revealed something immediately useful. The tech team skewed heavily towards Introversion, as expected. But a handful of team members had notably different profiles, with stronger Extraversion preferences.

The L&D team reframed it as an asset. The more extroverted individuals became natural bridge-builders. They were the people best placed to represent the tech team in cross-functional collaboration, because external engagement sits squarely within their preference.

That's the shift personality insights enable – from "why do they do that?" to "ah, now it makes sense, and here's how we use it”.

From good managers to great ones

The difference between a good manager and a great one often comes down to adaptability. Great managers don't treat every team member the same – they adjust their style to meet people where they are.

AI coaching makes this practical at scale. Rather than relying on expensive, infrequent coaching sessions, managers get micro-nudges and real-time guidance available 24/7. Billee learns from previous conversations, builds a picture of your team over time, and surfaces relevant insight specific to your organisation – something a generic AI tool simply can't replicate.

When we embedded this into our management development programme, managers reported feeling far more confident going into difficult one-to-ones and more equipped to get real value from monthly check-ins.

And to top it all off, our HR software’s performance tools – including AI-generated review summaries and soon a Beta version of our AI chatbot – help managers surface the right insights at the right time. 

Key takeaways

• Personality insights for team performance aren't just 'nice to have' — they're commercially critical – impacting performance, retention, engagement, and leadership effectiveness

• MBTI identifies natural preferences across four dimensions: energy, information processing, decision-making, and structure

• Understanding personality differences reduces conflict, improves collaboration, and helps managers adapt their style

• AI coaching tools like MyTeamBuilder make personality insights actionable in everyday moments – not just in workshops

• The combination of self-awareness and smart technology is what takes teams from performing to thriving
