An organizational chart usually looks convincing: leaders, departments, job titles, reporting lines, and clearly defined responsibilities. It tells you who assigns work, where decisions are expected to travel, and where one team formally ends and another begins. Watch the work itself for a few days, however, and that tidy picture begins to blur.
When someone needs advice, they may go to an experienced colleague rather than their manager. When a company changes a process, employees read the guidance and attend the presentation, then watch the reaction of the one or two people whose judgment they trust. Two departments may appear well connected on paper even though nearly all real communication has passed through one person for years.
The opposite happens too: an employee attends every meeting, completes their tasks, and belongs to the team on paper, yet gradually moves to the edge of its working life. Sociometry helps reveal this layer of the organization—the one an org chart cannot hold.
At a glance
- Sociometry maps relationships against one specific criterion, such as advice, trust, collaboration, or information flow.
- The quality of the result depends on a precise question and on participants having real experience of working together.
- A sociogram can reveal centers of influence, bridges between groups, bottlenecks, and people at the edge of a network.
- The map is a hypothesis to investigate, not a popularity ranking or a diagnosis.
- The strongest conclusions come from combining sociometry with surveys, 360-degree feedback, and conversations with employees.
If an org chart answers “How is the company formally organized?”, sociometry asks “How are people actually connected?”
What is sociometry?
Sociometry is a method for studying relationships and choices within a group. Participants select other members of the team against a defined criterion: whom they would approach for professional advice, with whom they would choose to tackle a difficult assignment, or whom they would trust with a workplace concern.
The American Psychological Association describes sociometry as the study of the structure of relationships among members of a group; the resulting patterns can be represented graphically as a sociogram.[1] The method is associated with Jacob Moreno, who proposed looking at a group not only through the characteristics of individuals but through the network of relationships between them.[1]
That distinction matters in HR. A company can hire strong specialists, define roles carefully, and establish good processes, yet still find that knowledge barely spreads, decisions depend on one expert, two halves of a department operate in parallel, and a newcomer remains on the edge of communication for months.
These patterns are difficult to see in a table of job titles. They become clearer when relationships—not only individuals—are the object of analysis.
What workplace sociometry can reveal
Imagine a department of twelve people. It has a manager, regular meetings, clear roles, and work that arrives on time. At first glance, the team looks stable.
Then a sociometric survey asks:
Which colleague do you approach first when you face a difficult work problem?
Seven people select the same senior specialist. When asked whom they would consult about a workplace change they were uncertain about, the same name appears most often.
The employee is performing a role that is absent from their job description. Knowledge travels through them; they explain decisions, help new starters, connect parts of the team, and often hear about tension first. Formally, they are an experienced specialist. In the real relationship network, they are one of the team's centers.
This does not mean they should immediately become a manager. It does reveal a dependency. When too many requests converge on one person, their influence is both an asset and a potential vulnerability.
Organizational Network Analysis applies similar logic at a broader scale. SHRM describes it as a way to identify hidden influencers, people who connect groups, and communication bottlenecks that formal structures tend to conceal.[2]
How to formulate sociometric questions
The question is especially important in sociometry because it determines which network you will see. Asking “Who do you most enjoy talking to?” and “Whom do you ask for professional advice?” creates two different maps of the same team.
There is no universal “main sociometry question.” Start with the aspect of collaboration you need to understand.
For professional connections, you might ask:
Which colleague do you approach first for help in a difficult professional situation?
With whom would you prefer to work on an important, highly uncertain assignment?
Whose opinion do you listen to most when making a work decision?
Who helps you understand new information or a new process more quickly?
Questions about trust and interaction need a different focus:
With whom could you openly discuss a workplace problem or mistake?
With whom is it easiest to reach agreement when your views differ?
Whom would you approach for support in a difficult work situation?
To explore cross-functional connections, ask: “Whom in another team do you contact most often to resolve work issues?”
One question does not measure “team relationships” as a whole. It maps choices against one criterion only, and that limitation must remain visible when interpreting the results.
How to build a sociogram and read the network
Sociometric results are commonly shown as a sociogram. Each employee becomes a node, and one person's choice of another becomes a directed connection. A mutual choice produces a connection in both directions.
On an org chart, a team might look simple:
Head of Engineering → Team Lead → Developers
The sociogram tells another story. Most developers seek advice from one senior engineer; the team lead mainly connects engineering with product; one employee maintains the link to another department; and another is barely included in colleagues' work-related choices.
The two diagrams do not contradict each other. They describe different layers. The org chart maps authority and accountability; the sociogram maps how trust, help, knowledge, or collaboration travels under the selected criterion.
A practical process looks like this:
- Define the group and confirm that its members genuinely work with one another.
- Select one criterion tied to a clear research objective.
- Ask each participant to name a limited number of colleagues.
- Put the choices into a matrix: rows show who chooses, columns show who is chosen.
- Draw a network with directed links and distinguish mutual choices.
- Look for patterns—not “winners” and “losers,” but centers, bridges, clusters, peripheral nodes, and single points of dependency.
Informal leadership: influence without a title
The gap between formal authority and real influence becomes especially visible during change. A company introduces a process, runs training, publishes guidance, and has managers explain the rationale. A few weeks later, part of the team is still working in the old way.
“Employees resist change” is the simplest explanation. The reality may be more useful: the people whom colleagues genuinely trust have not accepted the new approach. Official information travels downward while its practical interpretation travels sideways, through conversations between peers.
Sociometry can reveal whose judgment carries weight in the group. The goal is not to use those people to pressure everyone else. It is to involve them earlier, hear their arguments, and understand how a decision is being interpreted inside the team.
CIPD also points to the limitations of a purely hierarchical view: formal structures do not necessarily reflect the informal relationships through which people receive information and make sense of change.[3]
When an employee gradually falls out of the team
Consider an employee who joined five months ago. They passed probation, deliver work on time, and have no obvious performance problems. Formally, onboarding looks successful.
Yet the sociogram shows almost no connections. Colleagues rarely approach them for help, few select them for collaborative work, and mutual choices are scarce.
That result proves nothing on its own. The role may be highly autonomous; the employee may prefer a small number of contacts; or the question may simply be irrelevant to their work. But the pattern becomes more meaningful if the same person reports weak colleague relationships, says in one-to-ones that they do not know whom to ask for help, and remains largely absent from team discussions.
Sociometry does not make a diagnosis. It identifies somewhere worth looking more closely. One signal may not justify a conclusion, but it may justify a good conversation.
When one team is really two
A twenty-person department may exist as one team only on the org chart. A shared manager, meetings, and objectives suggest one group, but the sociogram shows two dense clusters with very few connections between them.
If delays repeatedly occur at that boundary, it is easy to blame accountability or communication. Sociometry offers another hypothesis: the people were formally combined, but working relationships never developed.
That leads to more specific action. Create work that genuinely requires people from both clusters to collaborate, run knowledge exchanges, or pair colleagues across the old boundary. Then repeat the measurement to see whether new relationships have appeared.
The bridge employee: a quiet connection between teams
The most interesting person in a sociogram is not always the one with the most incoming arrows. Imagine sales and marketing: different goals, language, and habits make collaboration difficult, but one employee understands both sides and regularly carries context between them.
Their role may look unremarkable on the org chart. In the network, they are almost the only bridge. Information travels faster and misunderstandings decline because of them—but the same role creates risk. A holiday, internal move, or resignation can sharply reduce the connectivity of the whole system.
The analysis therefore asks not only “Who connects these teams?” but “What happens if this connection is temporarily unavailable?”
When the team star becomes a bottleneck
A team may have an expert who knows the product architecture, remembers the history of key decisions, helps colleagues, and advises other departments. They look like an ideal employee, yet the network can expose the other side of that success: too many requests converge on one person.
As the team grows, interruptions multiply and the expert gradually becomes an internal help desk. Work slows when they take leave. If employee listening data also shows rising exhaustion, there is a concrete hypothesis to explore: some of the overload may come from an informal network role rather than the formal workload.
Sociometry does not prove a causal link with burnout. It makes visible a form of demand that may be absent from the job description and task tracker.
Sociometric status is not a popularity contest
Many selections must mean “leader”; few selections must mean “outsider.” Apply labels like these and sociometry quickly turns into a questionable popularity ranking.
Every result depends on the question. If a person is frequently selected for “Whom would you ask for technical advice?”, they hold a prominent position in that professional network. It does not mean everyone likes them most, that they are the best employee, or that they should become a manager.
Someone else may rarely appear in the professional-advice network but sit at the center of a trust or support network. The phrase “high sociometric status” explains little unless it is followed by: high in relation to what?
What sociometry shows during organizational change
Growth, mergers of departments, leadership changes, and hybrid work can alter formal structures quickly while social structures change slowly. Two departments can be combined today and presented as a new org chart next week, yet months later people may still turn only to colleagues from their former teams.
Repeated sociometry reveals movement, not just a static map. Did connections develop between the combined groups? Have new starters become part of the network? Does one person remain a critical dependency?
The same principle applies to other employee research: after a change, measure the lived experience, not merely whether implementation occurred. For focused follow-ups between larger studies, see our guide to employee pulse surveys.
How sociometry differs from 360-degree feedback
Sociometry and 360-degree feedback both involve colleagues, but they answer different questions.
360-degree feedback shows how a person's workplace behavior is perceived by their manager, peers, direct reports, and the employee themselves. Sociometry looks beyond one person to the whole relationship network: who is asked for advice, where choices are mutual, who connects departments, and which parts of a team barely interact.
One method looks at an individual from several viewpoints. The other reveals the structure in which that individual works. Together, they create a more complete picture.
How sociometry differs from an engagement survey
An employee engagement survey shows how people experience their work, support, growth, recognition, manager, and environment. Sociometry studies links between named people.
In simple terms:
Engagement survey: “Do I receive support from colleagues?”
Sociometry: “Who exactly do I approach for support?”
The first question helps explain an employee's experience. The second maps the network in which that experience forms. The data complements rather than replaces each other.
How to run an employee sociometry survey
A sociometric survey may contain only a few questions, but length does not determine quality.
First, choose a group whose relationships are meaningful to analyze. Participants should know one another and have real experience of working together; otherwise many choices will be arbitrary. Then define the objective: knowledge flow, cross-functional bridges, trusted advisers, or connections around difficult decisions.
Ask participants to name a small number of colleagues who best match the criterion. Convert the answers into a matrix and a visual map showing mutual choices, central participants, clusters, peripheral people, and links between groups.
The work does not end with the picture. A sociogram answers “What can we see?” The next stage must ask “Why did this structure emerge?” That requires context, employee conversations, and other people data.
Conclusions sociometry cannot support on its own
A sociogram is visually persuasive, which is both its advantage and its danger. When one person sits at the center of ten connections and another appears almost alone, explanations come too easily.
Being selected rarely does not prove poor onboarding or conflict. A central position does not prove that someone is the best specialist or a ready-made manager. Two clusters do not necessarily signal a dispute; they may reflect a natural division of work.
Sociometry shows a structure that needs explaining, not an explanation ready to use. Strong conclusions come from comparing several signals: sociometry, employee surveys, 360-degree feedback, operational data, and conversations with people.
From “it feels like” to a testable hypothesis
Much of what we know about team life begins as an impression: “These departments still live separately,” “Everyone keeps going to the same person,” or “The newcomer performs well but has not become part of the team.”
Experienced HR leaders and managers often notice these weak signals accurately, but there is still a gap between intuition and a basis for action. Sociometry helps narrow it. Instead of “It feels like the teams have a problem,” there is a more precise observation: professional choices show almost no mutual connections between the two groups.
That is still not a diagnosis or a ready-made intervention. It does make the next question much clearer.
Sociometry in formeasure
In formeasure, sociometry can sit alongside other data about employee and team experience. A relationship map can identify centers for a particular type of interaction, mutual choices, bridge employees, and people at the edge of a selected network.
Few connections mean more when the employee also reports onboarding difficulties. An expert's central role deserves attention when workload indicators are deteriorating. A formally integrated team deserves another look when its relationships still follow an old organizational boundary.
The familiar HR question “What is happening with our people?” gains another dimension: “What is happening between them?”
The org chart shows how a company is organized. Sociometry helps show how it lives.
Frequently asked questions about sociometry
What is workplace sociometry?
Workplace sociometry is a method for studying relationships and choices within a team. Employees select colleagues against a defined criterion, and the resulting data reveals the structure of that network.[1]
What can employee sociometry show?
Depending on the question, it can show whom employees approach for advice, whom they trust, with whom they prefer to work, which subgroups exist, and who connects different parts of the organization.
What questions should a sociometry survey ask?
The question should match the research objective. Examples include: “Whom do you approach for professional advice?”, “With whom would you prefer to work on a difficult assignment?”, and “Whom would you ask to discuss a workplace concern?”
What is a sociogram?
A sociogram is a graphical representation of relationships within a group. Participants appear as nodes and their choices as directed links between those nodes.[1]
Can sociometry identify an informal leader?
It can identify people who are frequently selected against a particular criterion, such as advice or collaboration. Calling that person a universal “informal leader” without reference to the question and context would overstate the result.
What does it mean if no one selects an employee?
On its own, the result does not prove isolation, conflict, or poor onboarding. Interpret it in light of the question, the employee's role, the team's work, and other evidence.
How is sociometry different from 360-degree feedback?
360-degree feedback compares how different groups perceive one person's workplace behavior. Sociometry studies the structure of relationships across the whole group.
How often should a company run sociometry?
There is no universal schedule. Repeating it is particularly useful after events that can reshape relationships, such as a reorganization, department merger, rapid growth, leadership change, or shift in working model.
