Data is not insight, and insight is not wisdom

Melanie van Rooy started as an economist at the South African Reserve Bank, lectured econometrics, and built research units inside the Coca-Cola system before running marketing at the Clicks Group. Nobody's idea of a data sceptic. Which is exactly why her warning lands:

"You can have incredible data and brilliant technology, but data is not insight, and insight is not wisdom. You still need the experienced marketer who can interpret what matters, connect the dots and turn it into meaningful action."

The ladder most teams stop climbing

There are three rungs from a number to a decision, and most marketing teams stop on the first.

Data — what happened. Dashboards, tracking, reports. Cheap, abundant, and on its own, meaningless.

Insight — what it means. The interpreted pattern: why did this move, and what does it tell us about the customer?

Wisdom — what to do, and whether to act at all. Judgement built from experience, context and commercial sense. This rung can't be bought as a tool — it's the reason senior marketers exist.

Before acting on any metric, force it up the ladder: what does this actually mean, and what would a wise person do about it?

The four listening posts

Melanie's second, more surprising point is that qualitative understanding still matters — the words of customers tell you things data can't. Her list of where to actually listen: a real conversation, a normal focus group, an in-store observation, and sitting in the call centre hearing customers describe their frustration in their own words. (Her cheekiest aside belongs here too: if you're really good at Excel, you can still do some pretty amazing analytics. The tool was never the point.)

Bronwyn Pretorius describes the same judgement from the other direction. Asked how she knew her team needed to grow, she laughed: "I could give you a very scientific answer, or I could just tell you — I knew." But she grounds it immediately: the gut is trained by strategy. Because the refreshed Ackermans brand strategy defined the focus, the gaps were visible to anyone who'd internalised it. Her rule: always start with strategy, then ask whether the gap is a people problem, a strategy problem, or simply the wrong time.

That's what the wisdom rung looks like in a meeting room — the confidence to say "that doesn't make sense to me, explain it again," and the trained instinct to know when an answer doesn't add up.

Try this week: take the three metrics you looked at most this week and write one sentence of insight and one of action for each. If you can't, either stop tracking them or start interpreting them. Then book one hour this month at a listening post — the call centre, a store, a customer call. Notebook, not dashboard.
