Caution when building pregnancy models!

appregMany retailers know that if they could really anticipate our purchasing patterns and where it leads to – that this could be very beneficial to them since they could reach the customer quicker and more efficiently. And for many retailers “holy grail” application in the family or women’s segment is pregnancy prediction.

We all know that life of any individual or family is very different in terms of priorities, habits and shopping behavior – before and after baby is born. At very least no one should argue that it should be different. So, to be able to time such “earth-shattering” event where old world is gone and a new star is born – and then “help” that individual or family by paddling your own products ahead of competitors - can really get you large share of their wallets on purpose of serving their needs better than competitor. What is wrong with that? Well, few things can go wrong here, mostly in “privacy” department, and some “smarties” who went ahead of themselves eventually learned their lessons and they had to move a few steps back.

Lets’s start with conceptually outlying how you could build pregnancy predictive model, before putting a few warning signs, kind of “proceed with caution” or “danger ahead”.

The first thing you need to do is to put the "carrot on the hook" for any female customers who would be willing to share their pregnancy secret with you (first or second trimester preferable) for some hefty promotional discounts. Once you have a critical mass of newly pregnant customers – it is just a matter of capturing their purchasing history, so that you are able then to differentiate between them the rest (non-pregnant segmented) in the form of robust and accurate predictive model. Once, such model is in place it is a matter of implementing it, monitoring it and measuring value it generates.

All sound well and good - here is reality..

Once upon time there was one very clever man, in very clever marketing department of one forward-thinking retail company. And that man created a very smart data-mining model who could predict if woman customer is pregnant. Soon after mailing list followed to its likely pregnant female customers. As the story goes there were some very impressed customers who were amazed with “how did they know”? But they were some who were not so impressed, and they asked different questions of “how did they dare to know”? There were also some who felt wrongly “impregnated” like the father who stormed marketing department accusing them of leading his teenage daughter into getting pregnant - so they can sell to her their new range of baby products. But then, a few months later the same father end up sending letter of apology after discovery that his daughter was indeed pregnant!. Not to say that he was being completely stunned by how this retailer knew something he did not - even though his daughter lived with him.

The biggest problem was that many customers felt spied on, feeling that their privacy was compromised, so they started cutting ties with this retailer and doing everything they could to hide their purchasing behavior. This prompted retailer to adjust accordingly their model execution. And the only remedy was to blur the fact that they had such probabilistic knowledge. This resulted in promotions where baby-products coupons were masked with other vouchers, and therefore it was no longer obvious that marketers had such knowledge, which kept customers at ease. So, if you are competing for baby product market think carefully about how you navigate through this. Could be some stormy waters just when you think it is smooth sailing.
