Murphy’s First Law of Bad Data – If You Make A Small Change Without Involving Your Client – You Will Waste Heaps Of Money

I have not used my personal encounter with bad data management for over a year but a couple of weeks ago I was compelled to revive it.  Why you ask? Well, a complete stranger started to receive one of my friend’s text messages – including mine – and it took days for him to detect it and a week later nobody at this North American wireless operator had been able to fix it.  This coincided with a meeting I had with a European telco’s enterprise architecture team.  There was no better way to illustrate to them how a customer reacts and the risk to their operations, when communication breaks down due to just one tiny thing changing – say, his address (or in the SMS case, some random SIM mapping – another type of address).

Imagine the cost of other bad data (thecodeproject.com)

In my case, I  moved about 250 miles within the United States a couple of years ago and this seemingly common experience triggered a plethora of communication screw ups across every merchant a residential household engages with frequently, e.g. your bank, your insurer, your wireless carrier, your average retail clothing store, etc.

For more than two full years after my move to a new state, the following things continued to pop up on a monthly basis due to my incorrect customer data:

  • In case of my old satellite TV provider they got to me (correct person) but with a misspelled last name at my correct, new address.
  • My bank put me in a bit of a pickle as they sent “important tax documentation”, which I did not want to open as my new tenants’ names (in the house I just vacated) was on the letter but with my new home’s address.
  • My mortgage lender sends me a refinancing offer to my new address (right person & right address) but with my wife’s as well as my name completely butchered.
  • My wife’s airline, where she enjoys the highest level of frequent flyer status, continually mails her offers duplicating her last name as her first name.
  • A high-end furniture retailer sends two 100-page glossy catalogs probably costing $80 each to our address – one for me, one for her.
  • A national health insurer sends “sensitive health information” (disclosed on envelope) to my new residence’s address but for the prior owner.
  • My legacy operator turns on the wrong premium channels on half my set-top boxes.
  • The same operator sends me a SMS the next day thanking me for switching to electronic billing as part of my move, which I did not sign up for, followed by payment notices (as I did not get my invoice in the mail).  When I called this error out for the next three months by calling their contact center and indicating how much revenue I generate for them across all services, they counter with “sorry, we don’t have access to the wireless account data”, “you will see it change on the next bill cycle” and “you show as paper billing in our system today”.

Ignoring the potential for data privacy law suits, you start wondering how long you have to be a customer and how much money you need to spend with a merchant (and they need to waste) for them to take changes to your data more seriously.  And this are not even merchants to whom I am brand new – these guys have known me and taken my money for years!

One thing I nearly forgot…these mailings all happened at least once a month on average, sometimes twice over 2 years.  If I do some pigeon math here, I would have estimated the postage and production cost alone to run in the hundreds of dollars.

However, the most egregious trespass though belonged to my home owner’s insurance carrier (HOI), who was also my mortgage broker.  They had a double whammy in store for me.  First, I received a cancellation notice from the HOI for my old residence indicating they had cancelled my policy as the last payment was not received and that any claims will be denied as a consequence.  Then, my new residence’s HOI advised they added my old home’s HOI to my account.

After wondering what I could have possibly done to trigger this, I called all four parties (not three as the mortgage firm did not share data with the insurance broker side – surprise, surprise) to find out what had happened.

It turns out that I had to explain and prove to all of them how one party’s data change during my move erroneously exposed me to liability.  It felt like the old days, when seedy telco sales people needed only your name and phone number and associate it with some sort of promotion (back of a raffle card to win a new car), you never took part in, to switch your long distance carrier and present you with a $400 bill the coming month.  Yes, that also happened to me…many years ago.  Here again, the consumer had to do all the legwork when someone (not an automatic process!) switched some entry without any oversight or review triggering hours of wasted effort on their and my side.

We can argue all day long if these screw ups are due to bad processes or bad data, but in all reality, even processes are triggered from some sort of underlying event, which is something as mundane as a database field’s flag being updated when your last purchase puts you in a new marketing segment.

Now imagine you get married and you wife changes her name. With all these company internal (CRM, Billing, ERP),  free public (property tax), commercial (credit bureaus, mailing lists) and social media data sources out there, you would think such everyday changes could get picked up quicker and automatically.  If not automatically, then should there not be some sort of trigger to kick off a “governance” process; something along the lines of “email/call the customer if attribute X has changed” or “please log into your account and update your information – we heard you moved”.  If American Express was able to detect ten years ago that someone purchased $500 worth of product with your credit card at a gas station or some lingerie website, known for fraudulent activity, why not your bank or insurer, who know even more about you? And yes, that happened to me as well.

Tell me about one of your “data-driven” horror scenarios?
