Schumpeter – Why companies struggle with recalcitrant IT | Business

IT IS SUPPOSED to be the “Tesla killer”. Volkswagen’s new ID.3 is the firm’s first mass-produced all-electric car—and the first step in the German carmaker’s attempts to reinvent itself for an electrified world. That makes it perhaps the most important model since the original Golf, launched in 1976. The ID.3 is also late. Mechanically, the car is hunky-dory. But some software widgets that are a big selling point these days—rumoured to include smartphone connectivity and augmented-reality parking assistance—may be missing at first, only to be added later. Originally set for this summer, the launch has been pushed back until at least September.

VW is not the only big company struggling to make its computers work. Last year British banks were hauled over the coals by regulators for online outages and botched IT upgrades that left millions of customers unable to make or receive payments. Some problems are much more serious. Boeing’s 737 MAX aircraft were grounded in 2019 after two fatal crashes caused partly by a software flaw. Investigators have since found lesser bugs. Airlines are, for instance, now advised to turn the plane off and on again every 51 days, to stop its computers displaying false data in mid-flight. A similar problem found in 2017 in some aeroplanes made by Airbus, Boeing’s European rival, prompted the European Union Aviation Safety Agency to require that such aircraft be rebooted at least every 149 hours.

Blame for companies’ IT woes often ends up in the boardroom. Sometimes that is fair; Dennis Muilenberg was rightly forced to resign as Boeing’s CEO after the tragic 737 max disasters. But not always. For software is hard—and hard to keep up with. And the employees expected to produce it are often the products of a discipline that is in many ways oddly premodern. When software is “eating the world”—Silicon Valley speak for a situation where most firms are to a greater or lesser extent software companies—that matters.

Start with the computer code itself. Programming requires a mix of hyper-literalness and creativity. Tiny errors, like a misplaced punctuation mark, can completely change how a system behaves. An industry rule of thumb is that, depending on how carefully they work, programmers make between 0.5 and 50 errors in every 1,000 lines of code they write. Because cars and aircraft contain tens of millions of lines, the chances of an error-free system are in effect zero. Even when bugs do not lead to catastrophe, they put a constant drag on a firm’s productivity. A survey commissioned by Stripe, a digital-payments processor, suggested the average developer spends 21 hours a week fixing old or bad code.

The inherent difficulty of programming is made worse by the shortcomings of software engineering as a profession. These are laid out in a book, “The Problem With Software: Why…
