How to spot early signals before they become problems

Early signals are, by definition, small. They do not look like problems yet. They look like a slight dip in the score, a participation rate that is a little lower than last cycle, a team that has been sitting slightly below the organisational average for a few weeks. None of these seem urgent. All of them are worth paying attention to.

What early signals actually look like

Early signals in people data rarely announce themselves. They tend to be gradual and easy to rationalise. The score drops a couple of points - probably just a busy period. Participation is down in one team - probably just timing.

The rationalisations are often correct. Most early signals do not develop into problems. But some do - and the ones that do are identifiable in advance, if you are watching closely enough.

The signals worth watching most closely

Not all movement in a score is significant. The patterns that most often precede problems are:

  • A gradual, multi-cycle decline that does not recover - this is the clearest early signal of a persistent issue
  • A sudden sharp drop in a specific team while the rest of the organisation holds steady
  • A consistent gap between one part of the organisation and the rest that has been widening rather than narrowing
  • A decline in participation alongside a decline in score - this double signal may mean that the people feeling most negative are also least confident in responding

How to distinguish signal from noise

The practical heuristic is duration. A single cycle of movement is almost always noise. Two consecutive cycles moving in the same direction is worth noting. Three or more is a pattern worth investigating.

What to do when you see an early signal

When a pattern emerges that is worth paying attention to, the first response should be curiosity rather than intervention. What was happening in this team or period? If the context explains the movement and it resolves, the signal was informative but not urgent. If the movement continues, that is when a more direct response is warranted.

The takeaway

Early signals are only visible if you are measuring frequently enough to see them before they become trends. The habit of watching gradual movement - in score, in participation, in the gap between teams - is what creates the early-action advantage.
