Ignore legacy software at your own risk

Sharon Florentine | Sept. 18, 2015
Software might be the most important piece of legacy technology your company has. It can be a competitive advantage, but if not handled correctly, legacy code could also could be your biggest weakness.

Of all the legacy technology running behind the scenes in your business, software might be the most important. But it's also the technology with the greatest potential for failure. Your legacy software can be a great organizational asset, or it can be your biggest weakness.

The quality of legacy software code is a topic most CIOs like to avoid -- as long as it's still running, there's no reason to worry about it, right? "It's really hard to rally an organization around this, because there's a bit of a learned helplessness, and a vested interest in the status quo," says Lev Lesokhin, executive vice president of Strategy and Analytics, CAST Software.

Even CIOs who are "change agents," warns Lesokhin, who come in to try to address these issues don't tend to last very long. "They'd rather think short-term success and cross their fingers and hope that this is a long-term issue that's not going to affect them during their tenure," he says.

Under pressure

CIOs, too, are under tremendous pressure to devote the majority of IT budgets toward research and development and towards new initiatives, applications and features based on customer demands than on shoring up existing resources, even though both are in service of the larger goal -- measuring outcomes and addressing customer requirements.

That's all good, until a catastrophic failure happens. "The dirty little secret of IT is that most organizations -- based on our own research and anecdotes from our own customer base -- have something in the range of 15 to 20 incidents related to legacy software problems or failures each week. They're usually not big enough to capture media attention, and businesses are really good at covering them up. But don't worry - you'll get your turn on the cover of the Wall Street Journal soon enough if the issue's not addressed," Lesokhin says.

Tackling the issue requires a steady, firm hand and a lot of leadership from C-level management. It's a pretty sure bet your IT department and your developers are aware of the problems, and so are your customers.

Making sure the entire organization is on board with fixing issues of software quality should be a big priority for a savvy CIO. "CIOs walk a fine line of needing to balance the old, existing problems with software and delivering new products, services and initiatives. But there's a reluctance on the part of developers to speak up to management and say, 'Look, let's take a sprint and go back and fix these legacy, foundational issues so we can move faster on these new, emerging apps,'" says Lesokhin. Then the issue becomes a hot potato, bouncing back and forth between the CIO, IT, QA, with no one stepping up to actually address the underlying problems until it's too late, he says.
