### 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.

Columbia space shuttle uses radar as a time machine 

It is a hostile wasteland of flat sands and marching dunes, where the temperatureshave soared to 122° F, and the rain falls only once in 30 to 50 years. But for thousands of years, there have been tales that the Sahara’s arid surface concealed a “large river without water.” Last week a team of scientists from the U.S. and Egypt announced that they had definitive evidence that long ago a region of the vast desert in southern Egypt and northern Sudan was a lacy network of major water ways. The proof: radar images of the Sahara taken by the space shuttle Columbia. 

The discovery, reported in Science, was a serendipitous success for the flight of Columbia in November 1981\. That mission had to be cut from 124 hr. to 54 hr. because of a faulty fuel cell, but before aborting the flight, the astronauts were able to complete an experiment with the ship’s radar equipment. They took a 50-km-wide scan of the Sahara from the shuttle. Radar waves generally penetrate only a few centimeters of the earth, since the beams are dissipated by moisture in the surface of land. But in the dry Sahara, the radar waves were able to pierce to depths of five meters, reflecting from bedrock. 

The signals were processed through image-enhancing computer techniques. The resulting X ray-like pictures of the Sahara’s subsurface were then analyzed by scientists from the U.S. Geological Survey, the University of Arizona, the Jet Propulsion Laboratory in Pasadena, Calif., and the Egyptian Geological Survey and Mining Authority. The images of the area, says U.S.G.S. Research Geologist Carol Breed, “showed us a topography that could only have been buried. There was no trace of it on the surface.” Marvels the head of the eight-member group interpreting the pictures, John F. McCauley of the U.S.G.S.: “We were able to look through and use radar as a time machine.” 

The images revealed stream channels, broad flood plains and what millenniums ago had been great river valleys, some as wide as those of the Nile. Though a few experts speculate that the ancient and modern water systems were once connected, there is no supporting evidence. In fact, says McCauley, “the trending of the \[ancient\] rivers is to the south and west, the opposite of the present-day movement. It is possible they all joined up to one large basin of interior drainage as large as the Caspian Sea is now.” 

The find confirms that the region was once wet enough to support plants, animals and man, which scientists have long suspected. The Sahara originally dried out 2 million years ago, as the earth slipped into an Ice Age, but brief rainy periods occurred about 200,000, 60,000 and 10,000 years ago. Researchers who have ventured into south-central Egypt have found artifacts of human occupation. The U.S.Egyptian team that visited last September found the area so dry that cardboard boxes, cigarette papers and tracks left by the British army during World War II were perfectly preserved. Seeking signs of earlier inhabitants, the team dug at sites along the banks of hidden riverbeds shown by the new radar maps. Their findings: tools and other artifacts presumably used as long ago as 200,000 years by Homo erectus, one of modern man’s ancestors. 

Geologists believe that radar scanning will be valuable in detecting modern waterways lying near the surface in arid areas. “If you want to look for water in the desert,” says Breed, “you would look for that type of site where ground water intersects the surface.” For archaeologists, the technique may help determine sites of early human habitation near former rivers and lakes. And, by indicating telltale subsurface features, it may prove a boon for geologists surveying for oil and minerals. 

Space officials are so excited by the radar technique that a follow-up mission for more sophisticated radar imaging has been approved for a shuttle flight in August 1984\. Says J.P.L.’s Charles Elachi: “The plan is to concentrate and get much more coverage of the Sahara region.” There is even talk of more radar missions to other planets. Radar pictures, which have already revealed some of the secrets under the clouds of Venus, may help scientists learn how planets developed. First choice would be Mars. The arid red planet’s surface is etched with channels remarkably similar to those found beneath the surface of the Sahara.
