Reference #93: Better People Analytics
You need relational analytics, not just people analytics, to understand your organisation. People analytics focuses primarily on employee attributes: traits — which don't change — such as ethnicity and gender; and state — which does change — such as age, tenure, or days absent.
Relational data captures interactions between multiple people. The number of cross-departmental communications each day is an example of relational data.
