Bringing the Sun to light

The closest star to Earth is also the best studied, but only recently have we truly begun to uncover its secrets.

For thousands of years, humans have worshipped the Sun. Our ancestors built monuments and temples to it, and used it to mark the annual cycle of seasons. For ancient Egyptians, their most important god, Re, was the personification of the Sun itself.

Today, we are no less in thrall to the wonders and mysteries of our nearest star. We’ve made strides in understanding its major systems and answered many questions about how it produces energy. But the Sun is far from an open book,

November–December 2024

Harvard Business Review (October 22, 2024) – The latest issue features:

Why Employees Quit

New research points to some surprising answers. 

Summary.   

The so-called war for talent is still raging. But in that fight, employers continue to rely on the same hiring and retention strategies they’ve been using for decades. Why? Because they’ve been so focused on challenges such as poaching by industry rivals, competing in tight labor markets, and responding to relentless cost-cutting pressures that they haven’t addressed a more fundamental problem: the widespread failure to provide sustainable work experiences. To stick around and give their best, people need meaningful work, managers and colleagues who value and trust them, and opportunities to advance in their careers, the authors say. By supporting employees in their individual quests for progress while also meeting the organization’s needs, managers can create employee experiences that are mutually beneficial and sustaining.

Personalization Done Right

The five dimensions to consider—and how AI can help

Summary.   

More than 80% of respondents in a BCG survey of 5,000 global consumers say they want and expect personalized experiences. But two-thirds have experienced personalization that is inappropriate, inaccurate, or invasive. That’s because most companies lack a clear guidepost for what great personalization should look like.

Authors Mark Abraham and David C. Edelman remedy that in this article, which is adapted from Personalized: Customer Strategy in the Age of AI (Harvard Business Review Press, 2024). Drawing on decades of work consulting on the personalization efforts of hundreds of large companies, they have built the defining metric to quantify personalization maturity: the Personalization Index. It is a single score from 0 to 100 that measures how well companies deliver on the five promises they implicitly make to customers when they personalize an interaction.

The authors argue that personalization will be the most exciting and most profitable outcome of the emerging AI boom. They describe how companies can use AI to create and continually refine personalized experiences at scale—empowering customers to get what they want faster, cheaper, or more easily. And they show readers how to assess their own business’s index score.

Mass. Exodus

Massachusetts is one of the richest states in the country — because it’s pricing out its own middle class. Why did the state stop building enough to house them?
