More Bad Software

By James Kwak

Last week BATS admitted that its software suffered from systematic problems for four years, failing to obtain the best execution price for about 250 customers and costing them about $400,000. That should be a giveaway: no self-respecting company would break the law just to steal $400,000 from its customers. This was a programming error, pure and simple.

Also last week, a RAND study revealed that, despite billions of dollars of investment, electronic medical records have done little to reduce costs for healthcare providers. This is more complicated than a simple programming error. The issue here is that projected savings of this kind are typically based on some model of how operations will be done in the future, and that model depends on perfectly-designed software functioning perfectly. Medical records systems apparently fall far short of this ideal: as the Times summarized, “The recent analysis was sharply critical of the commercial systems now in place, many of which are hard to use and do not allow doctors and patients to share medical information across systems.”

The common feature to these stories, however, is that big, complex, business software is really, really important—and a lot of it is bad. In many niches, it’s bad because there aren’t that many companies that serve that niche, it’s hard for customers to evaluate software that hasn’t been delivered and installed yet, and there are all sorts of legacy problems, particularly with integration to decades-old back-end systems. And most of the incentives favor closing the sale first rather than making sure the software works the way it should.

I don’t have much to add that I didn’t put in my Atlantic column on a similar topic last summer. Nothing has changed since then. So I’ll stop there.
