The Innovation Consultancy, a small team within the health care provider Kaiser Permanente, practices an expansive, service-focused version of innovation that is both rapid and economical in comparison with the conventional version. The team's members observe how health care providers interact with one another, with technology, and with patients, and how the patients respond. They take photographs, draw pictures, write stories, and try to capture experiences from the point of view of everyone involved. During KP MedRite, a project to reduce the error rate in dispensing medication to hospital patients, the team asked nurses what they thought was wrong with the dispensing process. The nurses usually replied, "Nothing." But when given a chance to make self-portraits, they would draw themselves with sad faces and frazzled hair. Interruptions appeared to be the leading cause of errors-so one of the resulting innovations was a bright yellow sash signaling that its wearer was not to be disturbed. KP's Chris McCarthy founded the Innovation Learning Network to accelerate knowledge transfer among peers in the nonprofit health care industry. One promising process that has emerged, Inflection Navigator, helps patients who've received a frightening diagnosis handle the consequent urgent tasks-follow-up tests, visits to specialists, decision making about treatment and care-with the aid of care coordinators. This innovation and others like it arise from a brand of creativity that transcends the media version of the health care debate.

Why is that question in the past tense? Because individuals can no longer feel confident that the details of their lives - from identifying numbers to cultural preferences - will be treated with discretion rather than exploited. Even as Facebook users happily share the names of their favorite books, movies, songs, and brands, they often regard marketers' use of that information as an invasion of privacy. In this wide-ranging essay, McCreary, a senior editor at HBR, examines numerous facets of the privacy issue, from Google searches, public shaming on the internet, and cell phone etiquette to passenger screening devices, public surveillance cameras, and corporate chief privacy officers. He notes that IBM has been a leader on privacy; its policy forswearing the use of employees' genetic information in hiring and benefits decisions predated the federal Genetic Information Nondiscrimination Act by three years. Now IBM is involved in an open-source project known as Higgins to provide users with transportable, potentially anonymous online presences. Craigslist, whose CEO calls it "as close to 100% user driven as you can get," has taken an extremely conservative position on privacy - perhaps easier for a company with a declared lack of interest in maximizing revenue. But TJX and other corporate victims of security breaches have discovered that retaining consumers' transaction information can be both costly and risky. Companies that underestimate the importance of privacy to their customers or fail to protect it may eventually face harsh regulation, reputational damage, or both. The best thing they can do, says the author, is negotiate directly with those customers over where to draw the line.

Rory Stewart, a Scot in his 30s, left his career in the British Foreign Office to walk 6,000 miles across central Asia and then spent a year with the Coalition Provisional Authority (CPA), which temporarily ran Iraq after the U.S.-led invasion. In this edited conversation with HBR senior editor Lew McCreary, Stewart describes his stint as deputy governor of the Maysan and Dhi Qar provinces and other experiences that taught him to balance principled commitment with canny pragmatism. Without much direction from Baghdad, Stewart and the other CPA delegates tried to create conditions of relative stability, prepare the way for democratic institutions, and orchestrate a modicum of cooperation among tribal and ethnic factions. But Iraqi distrust, compounded by security conditions that went from bad to worse, made progress extremely difficult. As he faced these challenges, Stewart drew heavily on lessons from his trek, particularly from his time in Afghanistan. The nature of that journey had sharpened his senses. He'd learned to quickly size up people and situations, so when he joined the CPA, he showed ingenuity, flexibility, and uncommon insight into Arab cultures. Now back in Kabul, Stewart is the CEO of the Turquoise Mountain Foundation, a nongovernmental organization devoted to preserving the city's old commercial district, teaching vanishing artisan skills to young Afghans, and developing markets for Afghan crafts. Stewart's foundation aims to reclaim some of the glory of Kabul's heritage while giving purpose to lives that might otherwise drift toward anarchy or nihilism.
