A team personality assessment that maps your whole team on the Big Five
Each person answers 60 questions in about 8 minutes. SMP Assess turns those Big Five profiles into one live map of the whole team: where you are covered, where you run thin, which subgroups could drift apart, and who your next hire should be. There is a real, working sample below, not a screenshot.

What is a team personality assessment?
A team personality assessment measures each member of a team on a validated personality instrument, then combines the individual profiles into a team-level picture: the working styles the group has in abundance, the ones nobody covers, the subgroups that could quietly pull apart, and the shape of the person who would complete it. The measuring is the easy half. Plenty of good instruments exist, including our own free Big Five personality test, which anyone can take in eight minutes.
The combining is the half that separates a useful tool from a poster. A team is not an average of its members. A project team with four meticulous planners and one chronic improviser does not have "above-average conscientiousness" in any way that matters; it has a delivery floor set by the improviser, and everyone on the team already knows it. A tool that averages that away is describing a team that does not exist.
So a serious team dynamics assessment has to do three things: measure each person with a credible instrument, combine each trait the way the research says that trait actually operates in groups, and present the result so that every profile stays dignified. No trait is bad. A team map exists to explain friction and locate gaps, not to grade human beings.
It is also worth naming what a team personality assessment is not. It is not a hiring gate (screening candidates is a different activity with different rules, covered by our personality test for hiring). It is not a clinical instrument, and it should never wander into one. And it is not a verdict: personality informs how a team works, it does not determine what any person can do.
Why the Big Five beats MBTI and DISC for team work
Most team offsites still run on types. MBTI sorts people into sixteen boxes, DISC into four quadrants, and both produce a pleasant afternoon of recognition ("that is so you"). Types are memorable, and that is a real virtue: teams that share vocabulary talk more honestly about their differences. The trouble starts when the boxes are asked to carry measurement.
Personality is continuous. There is no cliff between an introvert and an extravert, just a distribution most people sit in the middle of. When a type instrument forces a binary cut, two colleagues who are nearly identical can land in different boxes, and the same person can land in different boxes on different Tuesdays. Pittenger’s review of the MBTI documents exactly this retest problem, along with the thin evidence connecting type to workplace outcomes (Pittenger, 2005). The Myers-Briggs Company itself does not position the MBTI as a selection instrument. DISC has a similar shape: valuable as a communication vocabulary, rarely defended as a measurement of how teams perform.
The Big Five is where the actual team research lives. When Barrick, Stewart, Neubert and Mount followed 51 real work teams, the teams higher in conscientiousness, agreeableness, extraversion and emotional stability earned higher supervisor ratings for performance (Barrick et al., 1998). Bell’s meta-analysis of team composition found that in field settings, a team’s minimum agreeableness and its average conscientiousness were among the strongest personality predictors of team performance (Bell, 2007). Peeters and colleagues, aggregating across studies, put numbers on it: team-level agreeableness and conscientiousness correlate positively with performance (about .24 and .20), while wide variability on those same traits correlates negatively (Peeters et al., 2006). Modest effects, honestly reported, but they all point the same direction, and none of them were written in type language.
Our assessment measures the five traits with a 60-item inventory in the tradition of Soto and John’s BFI-2 (2017), the modern standard for Big Five measurement, and scores every member against adult norms. If you enjoy type vocabulary, keep it for conversation. Measure with traits. (For how role-based systems fit into this picture, see Belbin team roles vs the Big Five; for the pair-level view, the team compatibility test guide.)

How to read a team personality map
Five layers, each answering a question a team lead actually has.
Personality types in a team, plotted on one chart
The Overview opens with an interpersonal circumplex: every member placed on the two traits that govern how people engage each other, warmth across the horizontal (candid to warm) and social energy up the vertical (reserved to outgoing). Each dot sits at that person’s percentile against a general adult sample, so the chart reads at a glance: who drives and challenges, who steadies and supports, who works best focused and independent. Alongside it, the roster names each member’s work archetype in plain language, because "personality types in a team" are most useful as vocabulary the whole team shares. Both poles of every axis are strengths; the chart has no good corner.
Trait aggregation, done per construct
Here is the part most tools get wrong. Averaging every trait assumes every trait works the same way in a group, and the composition research says otherwise. The map reads each of the five traits with the operationalisation the literature supports:
The floor logic matters because of what Felps and colleagues called the bad-apple effect: a single member who withholds effort or violates the group’s interpersonal norms drags outcomes far out of proportion to their headcount (Felps et al., 2006). The map never uses that language about a person. It shows you the floor, tells you what the research says floors do, and leaves the judgement with you.
Faultlines: the split you cannot see in a meeting
Lau and Murnighan borrowed the term from geology: a faultline is a dormant dividing line that only matters when stress arrives (Lau & Murnighan, 1998). In teams, trouble rarely comes from one difference; it comes from several differences lining up, so that the same three people sit together on every axis. Thatcher and Patel’s review of 59 studies ties aligned subgroups to more conflict and lower cohesion (Thatcher & Patel, 2012). The map runs a deliberately conservative detector: it only flags a faultline when the team splits cleanly into two well-separated subgroups of two or more, and then it names the axis that divides them, so you can mix people across it before "us and them" hardens. Most teams get no flag at all, which is also worth knowing.
Big Five team roles, with the evidence graded
The Roles tab allocates the nine classic Belbin-style team roles (across action, people and thinking categories) to the members best placed to own them, using each person’s trait profile. Belbin’s insight, that balanced role coverage beats a lopsided team, has aged well; the strength of the trait-to-role links varies, so the map does something unusual for this industry: it grades its own evidence. Every role assignment carries a confidence tier, from empirically supported links down to face-valid ones, so you always know whether you are reading a finding or a reasonable inference. Coverage gaps (roles no one naturally fills) are listed just as plainly, and if one person tops three or more roles, the map says the bench is thin rather than pretending the load is shared.
Gap-fill: who would complete this team
The last layer looks forward. Fit research distinguishes supplementary fit (hire someone like us) from complementary fit (hire what we lack), and the evidence favours complements for team composition (Kristof-Brown et al., 2005). The map identifies the dimension your team leaves uncovered and describes the profile that would fill it; on the live sample above, the Fill the gap panel inside Manage members ranks the candidate pool by exactly that logic. It also reads the team’s motivation mix, and the Goal Fit picker lets you choose a strategic objective (ship reliably, innovate, turn a situation around, and five others) to see how far the current composition naturally supports it. When the next step is an actual vacancy, the same profile flows into structured hiring, where the stricter selection rules apply.
For a slower, decision-by-decision read of one specific team, the companion piece walks through a full team personality map on a sample seven-person team. And when the map has shown you a pattern worth working on, Big Five team building turns each pattern into a runnable exercise.
Team dynamics assessment options, compared honestly
A 5-to-50-person team has five realistic options. Here is what each one costs, measures, and leaves you holding.
Competitor pricing reflects public list prices and reporting as of mid-2026 and changes; confirm with each vendor. The honest summary: excellent enterprise instruments exist, and most are priced and packaged as if your nine-person team were a nine-hundred-person org.
The gap in this market is practical rather than scientific. Small teams get a choice between workshop theatre they cannot measure and enterprise contracts they cannot justify. A team of eight should be able to decide after lunch to map itself, spend eight minutes each, and spend the following week’s standup arguing productively about the result. That is the product this page is describing, and the free tier exists so you can check the claim before anyone pays anything.
Is it legal and ethical to assess your team?
Legally, team development is the low-stakes end of personality assessment. The bodies of regulation that make hiring tests demanding (selection-procedure guidance, adverse-impact analysis, automated-decision rules) attach to employment decisions: hiring, promotion, termination. A standing team reflecting on how it collaborates is making none of those decisions. That is why team use has quietly become the least controversial application of workplace personality data, and why it needs none of the compliance scaffolding that selection use rightly demands. (None of this is legal advice; if you plan to let team data touch employment decisions, treat it as selection data and take proper advice.)
Ethically, the bar is higher than the law, and it should be. Four ground rules make the difference between a team that learns something and a team that feels surveilled. First, consent and transparency: people take the assessment knowingly, told exactly what will be shared and why. Second, ownership: each member keeps their own full report; the personal document belongs to the person. Third, dignity: no trait is bad, so a map should never have a bottom of the class, and this one is written so that it cannot. Fourth, purpose: the map informs conversations about how the team runs. The moment it becomes a lever against an individual, you have left team development and should stop.
Run that way, the assessment tends to be the opposite of intrusive: it gives people a dignified vocabulary for differences everyone had already noticed and nobody had language for. Practical scripts for those conversations are in managing different personalities, and the case for wanting those differences in the first place is in personality diversity in teams.

Team personality assessment FAQ
What is a team personality assessment?
A team personality assessment measures each member of a team on a validated personality instrument, then combines the individual profiles into a team-level picture: which working styles the group has covered, where it runs thin, which subgroups could drift apart, and what a new hire would add. Done well, it uses continuous traits (the Big Five) rather than type labels, aggregates each trait the way the research says to, and treats the result as one input for better conversations, never as a verdict on any person.
Is the Big Five better than MBTI for teams?
For measurement, yes. MBTI sorts continuous traits into binary types, so two nearly identical colleagues can land in different boxes, and retests move a meaningful share of people across the line (Pittenger, 2005). The research linking team composition to team performance is written in Big Five terms, not type language. Types still make good conversation vocabulary; the practical compromise is to measure with traits and talk with whatever labels your team enjoys.
How many people do I need for a useful team map?
Two members are enough to compute a map. From three, you also get the interpersonal circumplex and a named team identity. Faultline detection switches on at four, because a subgroup needs at least two people on each side. The tool is built for teams of roughly 5 to 50; past that, map departments or pods separately rather than one giant chart.
Is it legal and ethical to assess my team?
Team development sits in a much lower-risk category than hiring, because no employment decision hangs on the result. The rules that govern selection procedures apply when a test screens candidates, not when an intact team reflects on how it works together. Ethically, the bar is transparency: tell people what is being measured and why, let each person keep their own report, and never use the map to single anyone out. None of this is legal advice; for selection use, see our hiring assessment, which is built for those rules.
Do team members see each other’s results?
Each person receives their own full personal report, and that copy is theirs. The Team Map itself is a group artefact: it names who anchors which strength, so treat it as something you present to the team together, not something you read about them in private. Teams that share the map openly get the real benefit, which is a common language for differences that were already there.
How long does a team personality assessment take?
About 8 minutes per person: 60 questions, phrased in plain workplace language, on any phone or laptop. The map recomputes the moment each report lands, so a team that starts after lunch is looking at its own map before the end of the day.
Can I use the same assessment for hiring too?
Yes. The same Big Five profile powers our hiring flow, with role benchmarks, structured interview guides, and the stricter guardrails selection requires. Many teams run it in both directions: map the current team, then use the gap-fill recommendation to shape the next hire and screen for it properly.
What does it cost?
Mapping your team is free to start, with no credit card. Paid plans exist for teams that want to run assessments continuously or at larger scale, and the pricing is published, so you will not need a sales call to find out.
Two related questions with pages of their own: whether you should even want a team of similar profiles (personality diversity in teams), and what to do when two specific styles keep colliding (team compatibility test). If your question is about culture rather than composition, start with the free culture fit test.
