Team survey correlation heatmap

Beacon’s people-analytics team uses a correlation heatmap to compare four survey measures at once. The diagonal cells are one because each measure is perfectly correlated with itself; the off-diagonal values indicate the direction and strength of the observed relationships. The chart helps reviewers locate relationships worth investigating, such as manager support and growth opportunities. It does not establish a causal explanation, and small or unrepresentative survey samples can make a colour pattern look stronger than it is. Before sharing it, compare the chart with the source table and make the scope explicit. A clear date range, population and unit help another reader interpret the pattern correctly and decide whether follow-up analysis is needed.
