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.

In 1956, when this photo was taken, that same mass was installed in a subcritical reactor assembly at Argonne National Laboratory. Here, a courageous — or heedless — engineer measures the relatively low levels of radiation the block emits. Corbis ### Steady as She Goes  Does this reactor in North Anna, Va., photographed here in March 2011, look scary? It should. While the average U.S. nuclear plant has a 1-in-74,000 chance of being damaged severely enough by an earthquake to release radiation, the North Anna plant faces 1-in-22,727 odds. The five plants most vulnerable to quakes are all on the East Coast: Indian Point, north of New York City; the Pilgrim plant, south of Boston; the Limerick plant, outside Philadelphia; the Sequoyah plants, near Chattanooga, Tenn.; and Beaver Valley, near Pittsburgh. Why are plants in the East at greater risk than those in the seismically precarious West? Because the Western plants have been hardened against earthquakes and the Eastern ones haven't. Paul J. Richards / AFP / Getty Images ### Too Hot to Handle  A worker at the Osiris reactor outside Paris operates potentially radioactive equipment at the safest remove possible in August 2005\. Osiris is not an operational reactor but rather an experimental facility where the nuclear industry tests new technologies and improves old ones. Lionel Bonaventure / AFP / Getty Images ### Tomorrow’s Solution  A 100-ton component is lowered into place in an experimental fusion reactor at the Max Planck Institute in Germany in April 2010\. Unlike nuclear plants, which create energy by breaking unstable atoms apart, fusion plants operate like the sun, driving atomic nuclei together and releasing energy in the process. So far, scientists have not succeeded in figuring out how to build a practical fusion reactor. The Max Planck plant will get its try when it is completed in 2014. Frank Hormann / AP ### Pioneer Plant  Scotland's Dounreay reactor, seen here during its 1956 construction, was Britain's first nuclear facility. The designers boasted that one ton of uranium could produce the same energy as a million tons of coal. No word on whether they spoke as loudly about the risks. Charles Hewitt / Picture Post / Getty Images ### Hot Core in a Cold Place  A technician unseals a fuel vessel — where massive amounts of energy are generated — in Greenland's Camp Century reactor in 1962\. Greenland is not nearly as rich in geothermal energy as its little neighbor Iceland is, and nuclear power helps fill some of the energy gap. W. Robert Moore / National Geographic / Getty Images ### Benign Name, Nasty Stuff  Iranian technicians in Isfahan feed yellowcake into a barrel before processing it into fuel in August 2005\. Remember yellowcake, the concentrated uranium powder former President George W. Bush erroneously insisted Saddam Hussein was hoarding to build weapons of mass destruction? The claim may have been false, but the powder is very real — and it's not just the good guys who have it. Reuters ### In the Wrong Hands  During a 2006 speech by Iranian President Mahmoud Ahmadinejad about the country's nuclear ambitions, museum chief Astan Quds Razavi held a shielded sample of enriched uranium. Nuclear fuel can be scary enough, but an unstable element in potentially unstable hands continues to have the world on edge. Reuters ### Vintage Tech  Like many facilities, Poland's Maria reactor, which went online in 1974 (and is shown here in 2007), immerses its core, fuel rods and other critical hardware in water. Immersion both provides cooling and helps contain radiation. Tomasz Paczos / PAP / Corbis ### Powering Down  Engineers walk around the edge of the reactor head during the Ignalina nuclear power plant's final days in 2009\. One of the conditions Lithuania had to meet to join the European Union was shutting down the Chernobyl-style facility (with all the Chernobyl-style weaknesses). Taking the reactor offline was a good thing in terms of public safety, but it left Lithuania more dependent than ever on gas supplies from Russia. Mindaugas Kulbis / AP ### Don’t Fall In  A technician at Germany's Kruemmel plant measures the temperature of a cooling pool filled with spent nuclear rods, July 2009\. It is pools very much like this that have gone dry at Japan's Fukushima Daiichi plant, causing so much danger — and so many headaches. AP ### Reducing the Risk  Workers at a nuclear plant in Santiago, Chile, lift a rack of enriched uranium out of a cooling pool before placing it in a transfer cylinder in February 2010\. As part of an international effort to secure nuclear material, Chile then shipped the uranium to the U.S. to be converted into safer, more stable reactor fuel.
