Innovation is thrilling when it actually happens in a business, but all too often it's the emptiest of buzzwords.

Last fall, our annual InformationWeek 500 rankings highlighted IT innovators like The Gap, UPS, Dish, and Home Depot that have turned great ideas into action using cloud services, data analytics, collaboration tools, and/or mobile apps. It's no small feat. But these are the exceptions.

What's more likely is an uninspiring parade of low-risk, incremental improvements. That's the rather dreary conclusion of an Accenture study of more than 500 executives from companies with more than $100 million of annual revenue.

If a company invests in a disruptive product or business model and the returns are disappointing, the pursuit of "the next big thing" dries up fast, and so do expectations and funding, the study found. Fool me once and… innovation is replaced by renovation.

Seventy percent of the respondents called innovation a top five priority, and 67% said they depend strongly on innovation for long-term success. However, more than half said their company has a sluggish innovation process. Only 34% agreed that their "organization has a well-defined innovation strategy," and 21% agreed that they "have an effective process for capturing ideas outside the company."

What's preventing companies from crossing the innovation threshold that Netflix, Amazon, and Apple seem to leap past every year? The study blamed two main factors:

After invention, companies still need to craft the business model, customer experience, and "ecosystem that helps expand the market."

Innovation breakdowns often get blamed on IT, marketing, and the C-suite being out of sync. Yet the 2013 InformationWeek Global CIO survey of IT executives downplayed that explanation. Respondents listed thin budgets and weak skill sets as innovation obstacles more than CEO resistance. Only 14% chose "CEO or senior executives discourage innovation" as a barrier, and only 18% picked "poor relationships with other business units."

Nevertheless, solid relationships can soften unless business units communicate consistently. And innovation is all but impossible without clear goals. According to the Accenture study, your best chance to confront innovation inertia while protecting yourself from risk is to go to senior management with a formal and systematic plan that emphasizes speed, present a well-defined business model that supports an ongoing revenue stream, and identify early on the risks (and rewards) of disrupting a market.

Accenture's survey results vouch for this systematic approach. Respondents from organizations that use a formal system for innovation reported better outcomes and satisfaction. Fifty percent of companies with a formal innovation plan "intend to transform their business in the next 3-5 years primarily with innovations." Only 25% of companies with an informal plan had such intentions.

In a recent column on LinkedIn, the innovation consultant and author Gijs van Wulfen echoed the need for a precise methodology to help "structure the chaotic start of innovation" so that the "results at the end of the innovation pipeline will improve." He outlined his 5-step FORTH method to tackle innovation. Here are some key points:

These are all good guidelines to get an innovation project going, but most IT and marketing teams will hit the fear-of-failure wall with senior management. Disrupting a market usually means disrupting reliable revenue streams. And that's a scary proposition for a CEO. A prime example of this fear unraveling a company was Kodak choosing not to invest heavily in disruptive digital cameras to protect its (dying) film camera sales.

CEOs will continue to pay lip service to innovation, but it's up to small innovation teams to knock on C-suite doors, present a formal plan, and convince senior managers to help throw down internal barriers to innovation.

If your company's leaders remain blind to the digital disruption that's reshaping our economy and culture, your employees will smell a rat. They will leave. And a nimble digital force inevitably will blindside your company. Just ask Borders, Blockbuster, and all the taxi companies that never saw Uber and Hailo coming.
