### 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.

 Shortly before noon on March 1, 1964, a four-engine Constellation operated by California’s Paradise Airlines smashed into a snow-covered mountainside near Lake Tahoe on the California-Nevada border. All 85 aboard were killed. Now, after a 16-month investigation of the crash, the Civil Aeronautics Board has released a report finding that if the plane had been flying only 300 ft. higher or 300 yds. to the right, the disaster might have been averted. According to the CAB, the crash was caused by pilot error, sloppy ground maintenance, faulty equipment—and the falsification of a weather report by a Paradise official.

Three days after the smashup, Paradise’s operating license was suspended. Later, when the outfit’s license expired, the Federal Aviation Agency refused to renew it. At the time of the crash, Paradise Airlines was a two-year-old, scheduled, intrastate California carrier, flying leased planes between Oakland, San Jose and Lake Tahoe. It also had permission to operate charter flights to and from the Tahoe area. The doomed plane, Flight 901A, was a combination chartered and regularly scheduled flight.

“Sticky” Altimeter. During the eight months before the crash, the Constellation’s compass system had been reported malfunctioning no fewer than eleven times. The CAB found that at the time the plane hit the mountainside, the compass may have been as much as 15° off. Only the day before, a Paradise pilot who was flying the plane had complained that his altimeter had been “sticky” during descents, remaining stationary for a while, then suddenly registering a 150-ft. to 200-ft. drop. As for the copilot’s altimeter, it registered 100 ft. below sea level when the plane was on the ground at sea level.

The night before its last flight, the aircraft and its instruments were serviced—after a fashion. Paradise had no maintenance crews or facilities of its own, farmed out all such work to an FAA-approved Oakland maintenance station with licensed mechanics. The CAB found that the mechanic who worked on the Paradise plane’s compass had never before dealt with one like it; moreover, he did not take the trouble to consult any available technical manuals for guidance. The altimeters were adjusted by another mechanic, who later told CAB investigators that he could not quite recall whether he had tightened a vital screw.

Flying Blind. Thus blinded before it ever left the ground, Flight 901A, piloted by Captain Henry Norris, 45, flew from Oakland to Salinas, where it picked up a party of 18 charter passengers for a one-day trip to the Tahoe casinos. The plane next landed at San Jose, taking aboard 63 more, filling it to its passenger capacity. At the San Jose stopover, Captain Norris received a weather report from the Tahoe Valley Airport. According to the CAB, Paradise’s Tahoe station manager, presumably unwilling to turn away a lucrative flight, had changed an official weather report, causing Captain Norris to believe that thin, broken clouds existed in the Tahoe area, where, in fact, there were heavy clouds, snow showers and icing conditions.

Approaching his destination confronted by weather conditions that he had not been led to expect, and flying a plane that was not equipped with de-icing devices, Captain Norris asked for and got permission to climb to 15,000 ft. At 11:21 a.m., he said that he could see the south shore of Lake Tahoe. Eight minutes later, he radioed: “Flight 901A . . .” Then his radio went dead.

The CAB surmised that Norris, finding himself in a blizzard as he started to land, abandoned his authorized approach and headed eastward at 9,000 ft. toward what he hoped would be clear sky. “Then, either because they believed they had sufficient altitude to clear the terrain or because they were unable to climb higher due to structural ice, the aircraft leveled off,” said the CAB. “At that time they struck the first trees and were unable to avoid the final impact with the mountain.”
