There is no denying it — transforming your firm into the “digital business” is not a piece of cake. In order to do that, you must know first that digital transformation touches every function of your business’ unit. Now is not the time to experiment; now’s the time to be at the top of the digital business industry.

Leadership teams must be prepared to think quite differently about how a digital business operates. Digital leaders set aspirations that, on the surface, seem unreasonable. Being “unreasonable” is a way to jar an organization into seeing digital as a business that creates value, not as a channel that drives activities. Some companies frame their targets by measures such as growth or market share through digital channels. Others set targets for cost reduction based on the cost structures of new digital competitors.

Either way, if your targets aren’t making the majority of your company feel nervous, you probably aren’t aiming high enough.

When Angela Ahrendts became CEO of Burberry, in 2006, she took over a stalling business whose brand had become tarnished. But she saw what no one else could: that a high-end fashion retailer could remake itself as a digital brand. Taking personal control of the digital agenda, she oversaw a series of groundbreaking initiatives, including a website (ArtoftheTrench.com) that featured customers as models, a more robust e-commerce catalog that matched the company’s in-store inventory, and the digitization of retail stores through features such as radio-frequency identification tags. During Ahrendts’s tenure, revenues tripled. (Apple hired Ahrendts last October to head its retail business.)

Netflix was another brand with an unreasonably aspirational vision. It had built a successful online DVD rental business, but leadership saw that the future of the industry would be in video streaming, not physical media. The management team saw how quickly broadband technology was evolving and made a strategic bet that placed it at the forefront of a surge in real-time entertainment. As the video-streaming market took off, Netflix quickly captured nearly a third of downstream video traffic. By the end of 2013, Netflix had more than 40 million streaming subscribers.

The skills required for digital transformation probably can’t be groomed entirely from within. Leadership teams must be realistic about the collective ability of their existing workforce. Leading companies frequently look to other industries to attract digital talent, because they understand that emphasizing skills over experience when hiring new talent is vital to success, at least in the early stages of transformation. The best people in digital product management or user-experience design may not work in your industry. Hire them anyway.

Tesco, the UK grocery retailer, made three significant digital acquisitions over a two-year span: blinkbox, a video-streaming service; We7, a digital music store; and Mobcast, an e-book platform. The acquisitions enabled Tesco to quickly build up the skills it needed to move into digital media. In the United States, Verizon followed a similar path with strategic acquisitions that immediately bolstered its expertise in telematics (Hughes Telematics in 2012) and cloud services (CloudSwitch in 2011), two markets that are growing at a rapid pace.

This “acqui-hire” approach is not the only option. But we have observed that significant lateral hiring is required in the early stages of a transformation to create a pool of talent deep enough to execute against an ambitious digital agenda and plant the seeds for a new culture.

A bank or retailer that acquires a five-person mobile-development firm and places it in the middle of its existing web operations is more likely to lose the team than to assimilate it. Digital talent must be nurtured differently, with its own working patterns, sandbox, and tools. After a few false starts, Wal-Mart Stores learned that “ring fencing” its digital talent was the only way to ensure rapid improvements. Four years ago, the retail giant’s online business was lagging. It was late to the e-commerce market as executives protected their booming physical-retail business. When it did step into the digital space, talent was disbursed throughout the business. Its $5 billion in online sales in 2011 paled next to Amazon’s $48 billion.

In 2011, however, Wal-Mart established @WalmartLabs, an “idea incubator,” as part of its growing e-commerce division in Silicon Valley—far removed from the company’s Bentonville, Arkansas, headquarters. The group’s innovations, including a unified company-wide e-commerce platform, helped Wal-Mart increase online revenues by 30 percent in 2013, outpacing Amazon’s rate of growth.

Wal-Mart took ring fencing to the extreme, turning its e-commerce business into a separate vertical with its own profit and loss. This approach won’t work for every incumbent, and even when it does, it is not necessarily a long-term solution. Thus Telefónica this year recombined with the core business Telefónica Digital, a separate business unit created in 2011 to nurture and strengthen its portfolio of digital initiatives. To deliver in an omnichannel world, where customers expect seamless integration of digital and analog channels, seamless internal integration should be the end goal.

The leaders of incumbent companies must aggressively challenge the status quo rather than accepting historical norms. Look at how everything is done, including the products and services you offer and the market segments you address, and ask “Why?” Assume there is an unknown start-up asking the exact same question as it plots to disrupt your business. It is no coincidence that many textbook cases of companies redefining themselves come from Silicon Valley, the epicenter of digital disruption. Think of Apple’s transformation from struggling computer maker into (among other things) the world’s largest music retailer, or eBay’s transition from online bazaar to global e-commerce platform.

Digital leaders examine all aspects of their business—both customer-facing and back-office systems and processes, up and down the supply chain—for digitally driven innovation. In 2007, car-rental company Hertz started to deploy self-service kiosks similar to those used by airlines for flight check-in. In 2011, it leapfrogged airlines by moving to dual-screen kiosks—one screen to select rental options via touch screen, a second screen at eye level to communicate with a customer agent using real-time video.

We see digital leaders thinking expansively about partnerships to deliver new value-added experiences and services. This can mean alliances that span industry sectors, such as the Energy@home partnership among Electrolux, Enel, Indesit, and Telecom Italia to create a communications platform for smart devices and domestic appliances.

Many organizations focus their digital investments on customer-facing solutions. But they can extract just as much value, if not more, from investing in back-office functions that drive operational efficiencies. A digital transformation is more than just finding new revenue streams; it’s also about creating value by reducing the costs of doing business.

Investments in digital should not be spread haphazardly across the organization under the halo of experimentation. A variety of frequent testing is critical, but teams must quickly zero in on the digital investments that create the most value—and then double down.

Often, great value is found in optimizing back-office functions. At Starbucks, one of the leaders in customer-experience innovation, just 35 of 100 active IT projects in 2013 were focused on customer- or partner-facing initiatives. One-third of these projects were devoted to improving efficiency and productivity away from the retail stores, and one-third focused on improving resilience and security. In manufacturing, P&G collaborated with the Los Alamos National Laboratory to create statistical methods to streamline processes and increase uptime at its factories, saving more than $1 billion a year.

Rising customer expectations continue to push businesses to improve the customer experience across all channels. Excellence in one channel is no longer sufficient; customers expect the same frictionless experience in a retail store as they do when shopping online, and vice versa. Moreover, they are less accepting of bad experiences; one survey found that 89 percent of consumers began doing business with a competitor following a poor customer experience. On the flip side, 86 percent said they were willing to pay more for a better customer experience.

A healthy obsession with improving the customer experience is the foundation of any digital transformation. No enterprise is perfect, but leadership teams should aspire to fix every error or bad experience. Processes that enable companies to capture and learn from every customer interaction—positive or negative—help them to regularly test assumptions about how customers are using digital and constantly fine-tune the experience.

This mind-set is what enables companies to go beyond what’s normal and into the extraordinary. If online retailer Zappos is out of stock on a product, it will help you find the item from a competitor. Little wonder that 75 percent of its orders come from repeat customers.

Leaders of successful digital businesses know that it’s not enough to develop just one or two of these traits. The real innovators will learn to excel at all seven of them. Doing so requires a radically different mind-set and operating approach.
