A panel discussion about change at the Page Society's Future Leaders Experience in New York last week got me thinking about how chief communication officers (CCOs) can help their enterprises make the case for change.

FLE session convener Wendi Strong, former CCO of USAA, asked if it's better to focus on the negative consequences of failing to change or the positive benefits of changing. The question referenced a gain frame/loss frame paradigm mentioned in an earlier presentation by Christopher Graves, global chair of Ogilvy Public Relations Worldwide, who has invested eight years in the study of brain science.

Generally speaking, Chris said, brain science shows that the fear of negative consequences is two to three times more motivating of behavior change than the anticipation of positive benefits. Even then, humans are highly capable of rationalizing a way to stick with the status quo.

Reflecting upon my own experience, I developed a hypothesis: I think you need both – the negative consequences to drive acceptance of the need to change, and the positive benefits to motivate the actions that change requires.

My experience suggests that it is often easier to undertake fundamental and uncomfortable change when the enterprise comes to the conclusion that it has no choice. When I was at Aetna, our company's business model became so controversial and rejected by stakeholders and its performance so deteriorated that it became abundantly clear to most of us that we had to change to survive.

I recognize that such a consensus is not always so readily apparent. In those cases, it's incumbent upon leaders to help stakeholders see the existential threat before it's inexorable. Good communication and effective storytelling are critical.

Once the willingness to change has been established, the question becomes, change to what? That's where the positive motivation to act comes into play. Again based on experience, I believe purpose is highly motivating, along with a convincing story that the company and the individual can not only survive, but thrive.

At Aetna, our new leaders, CEO Jack Rowe and President Ron Williams, sketched out a vision for a new business model that they believed would produce a company turnaround. It involved a huge bet that physicians and patients could be motivated to adhere to evidence-based medical practices if they were convinced by data. That meant we would increasingly rely on the good will and good sense of others to achieve the cost control that business success required. Virtually everyone in the company would be obligated to learn new ways of working.

Our employees' willingness to take the journey proposed by Jack and Ron developed over time as the leaders forged with them a shared belief that the new approach would help Aetna's members achieve health and financial security and that, in return, the company's business would rebound and prosper.

It was a long path, and there was plenty of skepticism at first. The pain of layoffs and difficult changes necessarily preceded any tangible results. Jack and Ron worked hard to be realistic about the difficulties while simultaneously celebrating even small successes. Their ongoing mantra was under-promise and over-deliver.

It took six years of hard work, but the people did change and the Aetna story became one of the most successful business turnarounds ever, marked by high employee engagement and pride, new respect from doctors and patients and a 700 percent increase in market capitalization.

For CCOs seeking to help their enterprises build the case for change, my advice is to craft an authentic and convincing story that there is really no choice, combined with a compelling vision of a brighter future. I know: easier said than done. That's why the work we do is so important in this time of disruption and constant change.
