The sentence in the numbers

A woman in Doha sells eyeglass frames online from a spare room. Every Sunday morning she opens the week's figures. Visits, follows, saves, time on the page, messages, orders, returns, all sorted into tidy columns.

She reads them the way most of us read the weather forecast for a city we are not visiting. Interesting, and nothing to do with her.

That is what happens to most data. It costs almost nothing to collect, so it piles up, and a screen full of figures starts to feel like knowledge. Usually it is noise with good formatting.

Information is something else. It is data that has been worked on until it says something. It takes a position. It asks her to do one thing differently on Monday.

Somewhere in her columns is a sentence like this: most of the frames sent back this month were the same narrow style, bought by people with broad faces, because the photograph hides the width. That sentence is information. It changes the product page, the photographs and probably the next order to the supplier.

Nobody hands her that sentence. Someone has to go looking for it, test it against the returns, and throw away the twenty other stories the same figures could be made to tell. It is slow, unglamorous work, and most of what gets tried along the way ends up in the bin.

Adding another column is easy. Anyone can do it, and plenty do.

The rare skill is the one that turns a pile of figures into a reason to change your mind.
