7 programming myths -- busted!

By Neil McAllister, InfoWorld |  Development

These days, no one in their right mind thinks of launching a major software project without an offshoring strategy. All of the big software vendors do it. Silicon Valley venture capitalists insist on it. It's a no-brainer -- or so the service providers would have you believe.

It sounds logical. By off-loading coding work to developing economies, software firms can hire more programmers for less. That means they can finish their projects in less time and with smaller budgets.

But hold on! This is a classic example of the Mythical Man-Month fallacy. We know that throwing more bodies at a software project won't help it ship sooner or cost less -- quite the opposite. Going overseas only makes matters worse.

According to Brooks, "Adding people to a software project increases the total effort necessary in three ways: the work and disruption of repartitioning itself, training new people, and added intercommunication."

Let's assume that the effort required for repartitioning and training is the same for outsourced projects as for homegrown ones (a dangerous assumption). The communication effort required for outsourcing is much higher. Language, culture, and time-zone differences add overhead. Worse, offshore development teams are often prone to high turnover rates, so communication rarely improves over time.

Little wonder there's no shortage of offshoring horror stories. Outsourcers who promise more than they deliver are a recurring theme. When deadlines slip and clients are forced to finish the work in-house, any putative cost savings disappear.

Offshoring isn't magic. In fact, it's hard to get right. If an outsourcer promises to solve all of your problems for nothing, maintain a healthy skepticism. That free lunch could end up costing more than you bargained for.

Programming myth No. 2: Good coders work long hours

We all know the stereotype. In popular culture, programmers stay up late into the night, coding. Pizza boxes and energy-drink cans litter their desks. They work weekends; indeed, they seldom go home.

There's some truth to this caricature. In a recent analysis of National Health Interview Survey data, programming tied for the fifth most sleep-deprived profession. Long hours are particularly endemic in the video game industry, where developers must endure "crunch time" as deadlines approach.
