### FAQ

#### Is a PMP certification worth it?

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. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world.

Jan 15, 1990 5:00 AM UTC

On Jan. 27, 1950, a balding, bespectacled German-born physicist named Klaus Fuchs walked into London’s War Office and confessed to being a spy. For seven years, from 1942 to 1949, Fuchs had systematically funneled high-level secrets about U.S. and British nuclear-weapons research to the U.S.S.R., including plans for the yet unfinished hydrogen bomb.

Fuchs’ confession and subsequent trial marked a turning point in the history of the cold war. Evidence supplied in the confession led to the arrest of Julius and Ethel Rosenberg for what J. Edgar Hoover termed “the crime of the century” and prompted President Harry Truman to launch an all-out program to develop the so-called Super Bomb. Two and a half years later, thanks to the determined efforts of Edward Teller and colleagues at the Los Alamos Scientific Laboratory, the U.S. detonated the first thermonuclear device, beating the Soviets to the H-bomb by more than three years.

Fuchs’ betrayal of the H-bomb secrets passed into the folklore of the nuclear age. The folklore, however, is false. Fuchs’ H-bomb plans were totally misleading, and Truman’s rationale for rushing to build the bomb before the Soviets did was on shaky ground. That is the conclusion of an article in the January-February issue of the Bulletin of the Atomic Scientists, one of a series of scholarly works that are rewriting a period of U.S. history still shrouded in mystery and official secrecy. According to Daniel Hirsch and William Mathews, what Fuchs gave the Soviets was an early design of Teller’s that turned out to be unworkable. The crucial insight, they say, came after Fuchs had been imprisoned, and it was supplied not by Teller but by his Los Alamos colleague Stanislaw Ulam. Says Hirsch, former director of the nuclear- policy program at the University of California at Santa Cruz: “In many ways, Stan Ulam was the true father of the H-bomb.”

The key to the new account is a top-secret history of the H-bomb written by Hans Bethe in 1952 and only recently declassified. According to Bethe, who headed the theoretical-physics division at Los Alamos during World War II, Teller’s design began to fall apart shortly after Truman launched his H-bomb program. Teller’s idea had been to use the heat of a conventional A-bomb to ignite a separate H-bomb. But Ulam, a brilliant mathematician, made a series of calculations that showed that the amount of tritium fuel required for Teller’s bomb was prohibitive and that even when sparked by an A-bomb, it would probably not achieve fusion.

The breakthrough idea was the recognition that the fuel would burn more efficiently if it was compressed before it was heated. According to Bethe, Ulam approached Teller with a two-stage H-bomb design that used the shock waves from an A-bomb to compact the hydrogen and ignite the H-bomb. Teller adapted Ulam’s design, using the energy of the A-bomb’s radiation rather than the force of its shock waves to achieve the necessary compression. It was a bomb of this design, code named Mike, that exploded on Nov. 1, 1952, on the Pacific island of Elugelab. The island, one mile in diameter, disappeared.

If Fuchs did not give the Soviets the secret of the Teller-Ulam bomb, who did? Hirsch and Mathews suggest that Teller himself may have inadvertently – assisted the Soviets by pushing for an early test blast. The 1952 explosion peppered the atmosphere with a telltale assortment of radioactive debris, including new atomic elements that could have been created only by a compressed fusion reaction. When Hirsch and Mathews asked Bethe if that fallout could have tipped off the Soviets, Bethe instantly said yes. Says Hirsch: “It was as though he had been waiting 35 years for someone to ask him that question.”

The Hirsch and Mathews account has received mixed reviews from the surviving members of the Los Alamos team. Carson Mark, who took over for Bethe in 1947, concedes that the U.S. monitored the Soviets’ weapons research by examining the fallout from their blasts, but he doubts that the U.S.S.R. could have worked in the other direction, deducing the secret of Mike’s construction by studying its debris. Teller and others believe that the late Andrei Sakharov, who built the Soviet H-bomb, was clever enough to have invented the device from scratch, without the help of Fuchs or anyone else.

One participant who welcomes Ulam’s heightened status is his widow, Francoise Ulam, who will never forget the day she returned home for lunch to find her husband staring fixedly out the window. “I think I’ve found the way to make it work,” he told her. “Make what work?” “The Super.” Teller has partially confirmed his debt to Ulam. After suffering a heart attack in 1979, he dictated an account of the day Ulam walked into his office and said he had a way to make the bomb. Teller, though, heatedly disputes the notion that the key idea was Ulam’s. “That is not correct,” he says. “I do not want to say what is correct. It is a long and complicated story. Someday I will write it down.”

But history may have already been rewritten. The revised account of Ulam’s pivotal role appears in several new books, including a biography of Teller by Stanley Blumberg and Louis Panos to be published in February by Scribner’s. And it is repeated in detail in the latest revision of the New Encyclopaedia Britannica, due out next month.
