A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes.

Lepp / Corbis by [Michael Grunwald](https://time.com/author/michael-grunwald/) Mar 27, 2009 4:00 AM UTC If the Three Mile Island atomic reactor near Harrisburg hadn’t [melted down 30 years ago this Saturday](http://www.time.com/time/covers/0,16641,19790409,00.html)…well, there probably would have been an accident somewhere else. The entire U.S. nuclear industry was melting down in the 1970s, irradiated by spectacular cost overruns, interminable delays and public outrage. _Forbes_ later called its collapse “the largest managerial disaster in business history, a disaster on a monumental scale.” The TMI fiasco was a scary cultural moment, coming just two weeks after the release of the movie _The China Syndrome_, but there was nothing particularly tragic about it. It didn’t kill people. It didn’t kill nuclear power, which still provides 20% of U.S. electricity. It didn’t even kill TMI; the plant’s surviving reactor is about to receive a 20-year extension of its operating license. If anything, the core meltdown did some good, prompting desperately needed upgrades of nuclear safety standards. ([See the 10 worst nuclear disasters.](http://www.time.com/time/photogallery/0,29307,1887705,00.html)) No, the real tragedy was the dysfunction of the fledgling U.S. nuclear industry, which was already canceling new reactors all over the country before TMI, and has not ordered one since. That’s a shame, because nuclear reactors produce no carbon emissions. If we got 80% of our electricity from nukes today, as France does, we’d emit nearly a third less carbon. It would be the greenhouse-gas equivalent of taking all our cars off the road. So it would be nice if we could turn back the clock. The other tragedy is that we can’t. There’s huge hype these days about a “nuclear renaissance,” since the industry now has its act together, fossil fuels are frying the planet, and solar and wind are only intermittent electricity sources. But nuclear energy is still paying the price for the disastrous era that ended with TMI. And it’s too high a price. ([Read Nuclear’s Comeback: Still No Energy Panacea](http://www.time.com/time/magazine/article/0,9171,1869203,00.html).) The story of the original collapse of the American nuclear industry has been told many times. It is basically the story of an immature industry that grew way too fast, quintupling the size of its plants in just a few years, even as it was struggling with dangerously complex new technologies and an understandably onerous regulatory process, buffeted by plummeting electricity demand and soaring interest rates. The last nuclear plant ordered by a U.S. utility broke ground in 1973 and took 23 years to finish. The average cost overrun for a reactor approached 300%; the Washington Public Power Supply System—known as “whoops”—walked away from three plants mid-construction, triggering the largest municipal bond default in U.S. history. Even the reactor that failed at TMI was $500 million over budget and five years behind schedule. ([Read the original 1979 TIME cover story on Three Mile Island](http://www.time.com/time/covers/0,16641,19790409,00.html).) After TMI, the industry became radioactive. A famous NRC study found the potential for hundreds of thousands of deaths from a catastrophic meltdown. The federal government hasn’t met its responsibility to store nuclear waste, despite pouring billions of dollars into a hole in Nevada. Nuclear energy got caught up in the nuclear freeze, even though that was supposed to be about nuclear weapons, and the spread of terrorism and rogue states has lent some credence to fears of proliferation. After Chernobyl, [which was much worse than TMI](http://www.time.com/time/covers/0,16641,19860512,00.html), nuclear power seemed like way more trouble than it was worth. The good news is that today’s nuclear industry is no longer dysfunctional. It’s not perfect—an Ohio reactor nearly melted down in 2002, and the lead operator of a Florida plant recently quit after accusing his bosses of unsafe practices—but it has learned from its mistakes. Its reactors ran at a record 92% capacity last year. It’s doing a better job of storing its radioactive waste at its plants. It has standardized designs for new reactors, which should enhance safety, and it has successfully lobbied to streamline its regulatory process, which should reduce delays. And thanks to the climate crisis and a 30-year stretch without serious accidents in the U.S., no-nukes sentiment has faded; a Gallup poll this month found that 59% of Americans now support atomic power. The industry has an even broader base of bipartisan support in Congress, which continues to funnel it billions of dollars worth of loan guarantees, tax breaks, insurance benefits and direct subsidies; the latest goodie is “risk insurance,” which will reimburse the industry for regulatory delays. States are devising even more creative incentives for new plants; Florida has promised to pay utilities for nuclear investments even if they never complete any reactors, and may allow nuclear to qualify for renewable energy subsidies—even though it’s not renewable. [See pictures of the world’s most polluted places.](http://www.time.com/time/specials/2007/article/0,28804,1661031%5F1661028,00.html) [See the top 10 scientific discoveries of 2008.](http://www.time.com/time/specials/2008/top10/article/0,30583,1855948%5F1863947,00.html) The Nuclear Regulatory Commission has now received applications for 26 new reactors. If all goes well, the first could come online around 2016\. The first problem is, scientists believe we need to slash emissions now, in order to get back to 1990 emissions levels by 2020, and there’s no way new nuclear plants can even make a dent in the problem. Even if the industry’s backers got their wish of 45 new plants by 2030, that would barely replace the aging plants that are scheduled for decommissioning. Anyway, many of the new plants will never be built, and shouldn’t be built, because of a second problem: Once again, nuclear power is turning out to be way more expensive than originally advertised. The plants are cheap to operate, but [unbelievably costly to build](http://www.time.com/time/magazine/article/0,9171,1869203,00.html); estimates for new plants have doubled and even tripled over the last year or two. One recent study priced new nuclear generation at 25-30 cents per kilowatt-hour; new wind power comes in around 7 cents, about the same as coal, and investments designed to [reduce electricity consumption](http://www.time.com/time/magazine/article/0,9171,1869224,00.html) through more efficient appliances, lighting or buildings cost about 1 to 3 cents per kilowatt-hour saved. This is why nobody on Wall Street or Main Street or any private-sector street will make real investments in new nuclear generation; U.S. utilities rely on ratepayers and taxpayers, while France and China rely exclusively on public funds. A Warren Buffett-owned company was involved in an Idaho project, but scrapped it once costs began to escalate. And why are costs spiraling out of control again? Yes, the global credit crunch has increased the cost of borrowing, and oil spikes have increased the costs of materials. But ironically—tragically, really—the main problem has been the 30-year hibernation of the nuclear construction industry, the legacy of the incompetence that led to TMI. The specialized workforce of nuclear engineers, welders and other reactor-builders has withered, which means higher labor costs and more delays. Our nuclear industrial base has atrophied as well; for example, the world’s only steelworks capable of forging containment vessels is now a Japanese monopoly, forcing utilities onto a three-year waiting list to pay exorbitant prices. It’s too bad that nuclear plants make so little sense to build, because they’re great things to have once they’re up and running. If the nuclear industry hadn’t been so screwy before TMI, we might not be so dependent on filthy coal plants today. But we are. Now we have to make fresh choices about where to spend our energy dollars, and we don’t have the trillions of dollars it would take to solve our energy problems with a nuclear renaissance. As President Obama has said, nuclear power will remain part of our energy mix, but wind and efficiency are where we need to expand. Thirty years after TMI, nuclear power has turned out to be the Mickey Rourke of the U.S. energy industry — or maybe the Darryl Strawberry, a story of spectacular potential wasted by self-inflicted wounds. It got its act together in time to salvage a decent career, but oh, what it could have been.
