"Embrace change" is one of those awful, managerially correct Hallmark aphorisms celebrated in corporate-speak PowerPoint propaganda. The Give Change a Hug crowd swears that successful change management requires welcoming arms and open minds. They\u2019re wrong. Skepticism is best practice.Enterprise change hugging should be done with the same level of care as swimming with sharks or playing with porcupines: It\u2019s going to hurt no matter what you do. Change management is pain management (see "The New Science of Change" at www.cio.com\/091506). Tiny process nicks and subtle service cuts can lead to organizational inflammation and septic shock. But, hey, no pain, no gain, right?IT\u2019s accelerated innovation rate has spawned an enormous body of change management literature for CIOs. Almost all of it addresses how to turn change management into a reliable, robust and cost-effective process. Change is not an event. Change management\u2014like pain management\u2014is really process management, and change leadership is really process leadership. That\u2019s true for people, systems and apps.So where does successful process leadership come from? An IT Process Institute study provides compelling if counterintuitive insights that ring disturbingly true. Ordinarily, I dismiss self-reported IT shop surveys as self-serving drivel\u2014for example, "Do you have a formal change management process?" "But of course\u2026doesn\u2019t everyone?" "Are you a good boy?" "Yes, Mommy." There\u2019s good reason why so many CIOs view quasi-academic IT research with contempt.This survey was different. Questions were ruthlessly specific and difficult to cheat on. Inconsistent or contradictory answers would quickly surface. This survey had baked-in, value-added skepticism. Moreover, the researchers had selected key performance metrics that would quickly separate the weasels from the winners. I bit.The findings quantified distinctions between IT shops that live for the average and the few that take process leadership seriously. Elite IT performers weren\u2019t just two or three times better than median performers\u2014they were seven or eight times better. High performers\u2014roughly 13 percent of the 98 sampled\u2014contributed on average eight times more projects, four and a half times more applications and software, four and a half times more IT services, and seven times more business IT changes. They implemented 14 more changes with half the failure rate.We can quibble over the specifics, but that misses the central point: There were undeniably huge performance differences between the top quartile and the quartiles below. Why? What were the essential ingredients for process leadership?How the Elite InnovateThere was a simple, powerful and persuasive answer: foundational controls. That is, strict rules that clearly governed how change would be defined, monitored and thus led. Top-tier performers weren\u2019t change embracers or innovation huggers. They identified and enforced "process commandments" that constrained wasteful behaviors while reinforcing productive discipline. The researchers had picked a unit of analysis illuminating the core process values of their surveyed firms.Inspired by MIT\u2019s research on lean manufacturing, the IT Process Institute surveys zeroed in on the controls, not the metrics, the elite used to define and assure process discipline. Two controls towered over all others in impact and importance: Do you monitor systems for unauthorized changes? And are there defined consequences for intentional unauthorized changes? No ambiguity or nuance here. The key discriminator between the best and the rest was that elite performers rigorously monitored and punished unauthorized changes. They had situational awareness of change.The moment I saw this, a myriad of unresolved IT observations crystallized into clarity. What kills us is not our failures of planning, analysis, design, testing and deployment. It\u2019s not the work we\u2019re supposed to do that undermines our productivity; it\u2019s our black market economies of unauthorized changes\u2014no matter how well intentioned or essential. We misunderstand the true enterprise costs of change.Enterprises reluctant to punish unauthorized change agents guarantee dysfunctional cultures of lax discipline and process subversion. What makes this insight managerially excruciating is the simple truth that, in so many IT organizations, unauthorized fixes are sometimes the best and most important. We\u2019ve made it OK to scramble top coders to make swarms of not-quite-legit last-minute fixes. Think about that. Then ask, When was the last time your shop audited the impact of unauthorized changes? Take the next step: When was the last time your organization disciplined or dismissed the perpetrator of unauthorized changes?The survey identified a variety of high-impact controls\u2014call them lean controls\u2014that gave IT leaders greater leverage over their process investments. But the dominant finding was that unauthorized changes were a root cause of underperformance. IT shops that refused to take that shortcut had the best chance to be elite.A conversation with Gene Kim, one of the lead researchers, revealed that the elite performers didn\u2019t treat these controls as behavioral constraints but as platforms for innovation. Controls aren\u2019t straightjackets; they can be trampolines. By honoring controls, their developers had greater flexibility in process management because disciplined design and test proved more agile, robust and maintainable than unauthorized change. Their high-performance culture was a high-controls culture. Best practice was synonymous with best controls. Is that true for your firm? How would you know?The good news, says Kim, is that these controls are straightforward and easy to understand. What\u2019s more, elite performers had IT budgets roughly three times larger than median performers. Kim believes that "high performers have continually earned ever increasing budgets because they deliver ever increasing value to the business. The budgets of medium and low performers shrink or are only grudgingly increased by skeptical and suspicious CFOs who see IT managers failing to deliver projects and keep IT services running consistently."The more I talk with CIOs, the less confident I am that IT appreciates the role of controls in empowering leadership rather than imposing micromanagement. The IT Process Institute\u2019s results should provoke some rethinking about basic systems change management assumptions. The great systems software sage Fred Brooks was right: There are no silver bullets. But some ammo delivers far greater bang for the buck than others.
