Organizational network analysis (ONA)

Organizational network analysis maps how people actually communicate and collaborate, using data such as calendar meetings, email or chat metadata, or survey-based reports of who employees work with, and represents the organization as a network of connections rather than a reporting-line chart.

This differs sharply from an org chart or span of control view, which shows formal hierarchy; ONA often reveals that real collaboration and influence run through different people than the formal structure suggests, such as an individual contributor who is a hidden connector between otherwise siloed teams, or a manager who is formally central but informally disconnected from their own reports.

Companies use ONA to find collaboration bottlenecks, identify employees at flight risk because they sit at an overloaded network hub, and inform reorganizations so they do not break connections that matter more than the chart shows. Because ONA typically uses communication metadata, not message content, it raises real privacy concerns and works best when scoped narrowly, disclosed to employees, and aggregated rather than used to scrutinize individuals; it is often paired with employee engagement data and used as an input to workforce planning rather than as a standalone verdict on any one person.
