Senior Executives Get More Sleep Than Everyone Else

It’s no secret that most of us don’t get enough sleep and suffer for it. If you’re between the ages of 16 and 64, and don’t get seven to nine hours of sleep per night, your logical reasoning, executive function, attention, and mood can be impaired. Worse, severe sleep deprivation can lead to depression, anxiety, and symptoms of paranoia. In the long run, sleep deprivation is a main contributor to the risk of dementia and Alzheimer’s disease.
Surprisingly, one group that doesn’t need to heed these warnings is executives. In our assessment of 35,000 leaders and interviews with 250 more, we found that the more senior a person’s role is, the more sleep they get.
There are two possible explanations for this. Either senior executives, with the help of assistants and hard-working middle managers, do less and take more time for sleep. Or senior executives have had the wisdom and discipline throughout their career to get enough sleep and thereby maintain a high performance level without burning out.
Our conclusion is that the latter is the latter case. “Sleep has always been foundational for my performance,” Cees ’t Hart, president and CEO of Carlsberg Group, shared with us. “And especially to perform in a way that is required by my current job, I need seven hours of sleep, every night. Of course, with intense travel and work commitments,
sometimes this is compromised, and when that happens, it comes with a cost.
When I sleep less, I perform less.”
In contrast, our data found that 68% of nonexecutive leaders get five to seven hours of sleep per night. When there are not enough hours in the day, they steal some from the night. Many leaders stay up late to catch up on email or other tasks.
According to our research, this tendency is widespread, regardless of gender.
This is a problem. For leaders, sleep is not a luxury. Research has found that there is a direct link between getting enough sleep and leading effectively and that sleepdeprived leaders are less inspiring.
It used to be a badge of honor to brag about sleeping few hours, but our research should serve as inspiration for aspiring leaders to make sleep sacrosanct. The key message: If you want to be an effective leader, and rise in the ranks, get enough sleep.
Of course, it’s one thing to make a commitment to go to bed early, and another to actually get seven or more hours of quality sleep. For many leaders, going to bed is only part of the problem. The other part is getting high-quality, restorative sleep.
Fortunately, a good night’s sleep is not a random event; it’s a trainable skill. Here are a few guidelines that will help you.

Since the mid-2000s, organizational change management and transformation have become permanent features of the business landscape. Vast new markets and labor pools have opened up, innovative technologies have put once-powerful business models on the chopping block, and capital flows and investor demand have become less predictable. To meet these challenges, firms have become more sophisticated in the best practices for organizational change management. They are far more sensitive to and more keenly aware of the role that culture plays. They’ve also had to get much better on their follow-through.
Yet according to a 2013 Strategy&/Katzenbach Center survey of global senior executives on culture and change management, the success rate of major change initiatives is only 54 percent. This is far too low. The costs are high when change efforts go wrong—not only financially but in confusion, lost opportunity, wasted resources, and diminished morale. When employees who have endured real upheaval and put in significant extra hours for an initiative that was announced with great fanfare see it simply fizzle out, cynicism sets in.
Our experience with organizational change management suggests that there are three major hurdles to overcome. The first—no surprise—is “change fatigue,” the exhaustion that sets in when people feel pressured to make too many transitions at once. A full 65 percent of respondents to the Katzenbach Center survey reported this as a problem. The change initiatives they suffered through may have been poorly thought through, rolled out too fast, or put in place without sufficient preparation. Fatigue is a familiar problem in organizational change management, especially when splashy “whole new day” initiatives are driven from the top.
Change initiatives also flounder, according to 48 percent of the respondents, because companies lack the skills to ensure that change can be sustained over time. Leaders might set out eagerly to raise product quality, but when production schedules slow and the pipeline starts looking sparse, they lose heart. Lacking an effective way to deal with production line problems, they decide their targets were unrealistic, they blame the production technology, or they accuse their frontline people of not being up to the task. A much better way to solve the problem is to invest in operational improvements, such as process design and training, to instill new practical approaches and give people the knowledge and cultural support they need.
The third major obstacle is that transformation efforts are typically decided upon, planned, and implemented in the C-suite, with little input from those at lower levels. This filters out information that could be helpful in designing the initiative while also limiting opportunities to get frontline ownership of the change. In the Katzenbach Center survey, 44 percent of participants reported not understanding the changes they were expected to make, and 38 percent said they didn’t agree with the changes.
The following list of 10 guiding principles for change can help executives navigate the treacherous shoals of transformation in a systematic way.
1. Lead with the culture. Lou Gerstner, who as chief executive of IBM led one of the most successful business transformations in history, said the most important lesson he learned from the experience was that “culture is everything.” Businesspeople today understand this. In the Katzenbach Center survey, 84 percent said that the organization’s culture was critical to the success of change management, and 64 percent saw it as more critical than strategy or operating model. Yet change leaders often fail to address culture—in terms of either overcoming cultural resistance or making the most of cultural support. Among respondents whose companies were unable to sustain change over time, a startling 76 percent reported that executives failed to take account of the existing culture when designing the transformation effort.
Skilled change managers make the most of their company’s existing culture.
Why would this be true, given the widespread recognition of culture’s importance? Perhaps it’s because change management designers view their company’s culture as the legacy of a past from which they want to move on. Or they get so focused on structural details—reporting lines, decision rights, and formal processes—that they forget that human beings with strong emotional connections to the culture will be enacting these changes. Or they assume that culture, because it is “soft” and informal, will be malleable enough to adapt without requiring explicit attention.
Yet skilled change managers, conscious of organizational change management best practices, always make the most of their company’s existing culture. Instead of trying to change the culture itself, they draw emotional energy from it. They tap into the way people already think, behave, work, and feel to provide a boost to the change initiative. To use this emotional energy, leaders must look for the elements of the culture that are aligned to the change, bring them to the foreground, and attract the attention of the people who will be affected by the change.
In two healthcare companies undergoing a merger, culture led the post-deal integration. Using a culture-related diagnostic questionnaire, the change management team asked people to describe each company’s operating style—and mapped the responses from the two legacy companies to get a sense of their combined strengths and challenges. It quickly became clear that where one company had a culture attuned to bottom-line results, the other tended to focus on process. Optimally, the new company would need to skillfully use processes to deliver clear results. By first taking the time to recognize and acknowledge each company’s underlying culture, leaders of the merged firm harnessed deeply ingrained strengths to energize the change and avoided the incoherence that could have resulted from a less intentional and sensitive redesign.
2. Start at the top. Although it’s important to engage employees at every level early on, all successful change management initiatives start at the top, with a committed and well-aligned group of executives strongly supported by the CEO. This alignment can’t be taken for granted. Rather, work must be done in advance to ensure that everyone agrees about the case for the change and the particulars for implementing it.
A clinical research firm was committed to tripling its size over the next decade to achieve a more competitive position. Because the company was still pretty much operating as a startup after 25 years, this required a far-reaching organizational redesign. Before starting the design phase, finance leaders gathered at an off-site meeting to begin a rigorous exercise in alignment. The exercise included a leadership team effectiveness survey, which revealed that though these leaders called themselves a team, they didn’t really see themselves that way. Instead, they mostly operated as lone rangers, in characteristic startup style.
Each of the executives in the group made a thoughtful individual presentation about the case for change. Most of them agreed on the general direction the company needed to take to achieve rapid growth. But their descriptions of how to move in that direction—for example, what the first concrete steps should be—were all over the map. They were then tasked to work together to develop a case for change that every one of them could support.
To hammer out these agreements, these top executives had to listen closely to their colleagues and weigh conflicting points of view. The exercise was demanding, but they began to coalesce around a coherent vision for what the company should look like in 10 years. Most importantly, the experience of working together so intensely led the executives, for once, to act as a collaborative and committed team. By the end of the off-site meeting, they found that they were all using the same language to describe what the company needed to do. As one participant noted, the experience had transformed him, which in turn gave him confidence that together they could cascade the plan to other groups at other levels of the hierarchy.
3. Involve every layer. Strategic planners often fail to take into account the extent to which midlevel and frontline people can make or break a change initiative. The path of rolling out change is immeasurably smoother if these people are tapped early for input on issues that will affect their jobs. Frontline people tend to be rich repositories of knowledge about where potential glitches may occur, what technical and logistical issues need to be addressed, and how customers may react to changes. In addition, their full-hearted engagement can smooth the way for complex change initiatives, whereas their resistance will make implementation an ongoing challenge.
Planners who resist early engagement at multiple levels of the hierarchy often do so because they believe that the process will be more efficient if fewer people are involved in planning. But although it may take longer in the beginning, ensuring broad involvement saves untold headaches later on. Not only does more information surface, but people are more invested when they’ve had a hand in developing a plan. One common aphorism in change management is “you have to go slow to go fast.”
IBM recognized the need for such an approach in 2003, when rolling out a new initiative on culture. The leadership team had met intensively to develop clear definitions of the cultural traits the organization would require going forward. They then declared a “values jam,” a website set up for a 72-hour period, where anyone in the company could post comments, responses, suggestions, and concerns. Leaders then made key changes based on the feedback they received and communicated clearly how the input they’d received was being incorporated.
4. Make the rational and emotional case together. Leaders will often make the case for major change on the sole basis of strategic business objectives such as “we will enter new markets” or “we will grow 20 percent a year for the next three years.” Such objectives are fine as far as they go, but they rarely reach people emotionally in a way that ensures genuine commitment to the cause. Human beings respond to calls to action that engage their hearts as well as their minds, making them feel as if they’re part of something consequential.
Hewlett-Packard CEO Meg Whitman and her senior executive team appear to be following this principle in their transformation efforts. They have sought to activate a strong personal connection between HP and its employees, by drawing directly on the company’s cultural history and traditions. For example, through symbolic gestures such as tearing down the fences that surrounded the executive parking lot and moving top executives into cubicles, the company has reinforced the original “HP Way” ethic in which the intrinsic quality of the work is as important as one’s position in the hierarchy. (Whitman tells this story in an April 2013 LinkedIn blog post, “The Power of Transparent Communication.”) This strategy contrasts with that of Whitman’s immediate predecessors, who had declared it was time for the company to abandon its core identity. In any organization facing a challenging environment, the emotional connection fostered by moves like these is likely to make a major difference.
5. Act your way into new thinking. Many change initiatives seem to assume that people will begin to shift their behaviors once formal elements like directives and incentives have been put in place. People who work together on cross-functional teams will start collaborating because the lines on the chart show they are supposed to do so. Managers will become clear communicators because they have a mandate to deliver a message about the new strategy.
Yet lines on a chart and bold statements of intent have only so much impact. Far more critical to the success of any change initiative is ensuring that people’s daily behaviors reflect the imperative of change. Start by defining a critical few behaviors that will be essential to the success of the initiative. Then conduct everyday business with those behaviors front and center. Senior leaders must visibly model these new behaviors themselves, right from the start, because employees will believe real change is occurring only when they see it happening at the top of the company.
Leaders of a major global manufacturer seeking to escape bankruptcy believed the company had lost touch with customers because of entrenched problems in its culture. Managers operated in an overly layered system without much accountability. They were ponderous, risk averse, insular, and prone to spending time on approvals and office politics. Instead of implementing a dramatic, full-scale turnaround, the change team demanded that leaders adopt three specific behaviors:
