Organizational Network Analysis (ONA)

Organizational network analysis (ONA) is a method for mapping how work, information, and influence move between people. Each person is a point, each working relationship is a line, and the resulting picture shows how the organization operates in practice.

That picture often differs from the org chart. The chart shows who reports to whom. ONA shows who people actually ask for advice, who connects teams, and where information gets stuck.

How Is ONA Different From an Org Chart?

An org chart shows the formal structure: titles, reporting lines, and teams. It changes when someone is hired, promoted, or reassigned. It says nothing about how people collaborate day to day.

ONA describes the informal structure. A junior analyst whom five departments consult may matter more to daily work than a manager with few contacts. Looking at both views together helps you see where the formal design and real behavior drift apart.

What Data Does ONA Use?

There are two main sources, and many projects combine them. Surveys ask people short questions, such as whom they go to for advice or whom they trust to get work done. They capture the quality of a relationship but depend on people responding.

The second source is system data: metadata from email, calendars, and chat, such as who contacted whom and when. Umbrex's ONA framework describes this passive approach as needing metadata only, not message content. It scales well but cannot tell a friendly chat from a critical decision.

What Do the Main ONA Metrics Mean?

The terms sound technical, but the ideas are simple. You are measuring how connected people are, who sits between groups, and where clusters form.

Term	Plain meaning	What it can signal
Degree centrality	How many direct connections a person has	Key connectors, or someone overloaded with requests
Betweenness centrality	How often a person sits on the path between others	Brokers who link groups, and possible bottlenecks
Density	How interconnected a team or unit is	Low density can point to silos
Clusters	Tight groups with few ties to outsiders	Silos between functions or locations

A broker is someone who links two groups that would otherwise barely talk. If that person leaves, the connection can disappear without anyone noticing until work slows down.

How Do HR Teams Use ONA?

Change management is a common use. Before a reorganization, ONA shows who people turn to, so leaders can recruit trusted influencers as change champions. After a merger, it shows whether the two workforces are actually mixing or staying in separate camps.

It also helps with workload and development. Someone with very high connectivity may be carrying an invisible load and may be at risk of burnout. Someone on the edge of every network may be isolated or underused. Our entry on people analytics places ONA among the wider methods HR teams use.

What Privacy and Ethics Limits Apply?

ONA works with data about how people behave, so purpose and trust matter. Tell employees what is collected, why, and who sees the results. Use metadata rather than content, and report on groups instead of ranking individuals.

Do not turn it into a performance score. Umbrex's framework warns that using ONA as surveillance erodes trust, and that high activity is not the same as contribution. Privacy laws and works council rules vary by country, so involve legal counsel before collecting passive data.

How Does HR Cloud Fit Into Organizational Network Analysis?

HR Cloud's employee engagement analytics page says its reports let you see how employees are working together and identify trends and gaps in teamwork. It also describes real-time reporting on onboarding, collaboration, and recognition.

The page does not say what data those collaboration reports use, and it does not describe network mapping, centrality scores, or broker identification. Treat it as general collaboration reporting, not full ONA, and ask how the data is collected.

Frequently Asked Questions

Q: What is organizational network analysis?

A: It is a method that maps working relationships between people to show how information, advice, and influence actually flow through an organization.

Q: What is the difference between ONA and social network analysis?

A: ONA applies network analysis methods to the people inside one organization. Social network analysis is the wider field and covers any network of people or groups.

Q: Is ONA legal?

A: It depends on what data you collect and where your employees are. Survey-based ONA is usually simpler. Passive data may trigger privacy and monitoring rules, so check with counsel.

Q: Does ONA read employees' emails?

A: Well-designed projects do not. They use metadata, such as who contacted whom and when, and leave message content out of scope.

Q: What is a broker in ONA?

A: A broker is a person who connects groups that would otherwise have little contact. Brokers are valuable for sharing information but can become bottlenecks.

Q: What size company needs ONA?

A: It helps most when the organization is too large for leaders to see the networks themselves, or when major change such as a merger is underway. Small teams usually do not need it.
