### 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.

Since the earliest days of the Cold War, the U.S. military has been monitoring the skies over North America, ever-vigilant for a sneak attack. The task falls to U.S. Northern Command and the North American Aerospace Defense Command (NORAD) to identify and[ track potential threats](https://www.businessinsider.com/experts-call-for-norad-territorial-expansion-to-monitor-russia-china-2022-10) before they even cross into our airspace—be they Russian bombers or possible North Korean ballistic missiles. So how did it [miss at least four Chinese balloons](https://www.npr.org/2023/02/06/1154767882/this-wasnt-the-first-chinese-balloon-over-the-u-s-why-were-the-others-ignored) that had entered U.S. airspace in recent years, including near Texas, Florida, and Hawaii?

General Glen VanHerck, NORAD’s commander, admitted that the balloons exposed a “gap” in American air defenses. “I will tell you that we did not detect those threats,” he said.

The Pentagon has not released many details of other other balloons, but the one that was spotted over Montana on Feb. 1 was 200 feet tall and carried a payload of sensors and other equipment comparable to a small passenger jet. That balloon sparked a crisis after it lingered near sensitive U.S. nuclear missile sights before wafting over the middle of the continental U.S. and drifting out to sea off of South Carolina, where it was shot down by an Air Force F-22 stealth fighter jet.

While the U.S. is still working to determine how and why previous balloons escaped detection, experts say it may partly have to do with difficulties picking up inflatable airships on existing radar. And it could take deploying new technology and new strategies to make sure future balloons are spotted. “We don’t as a country have persistent sensors that can detect low profile and low heat signatures on our borders,” Riki M. Ellison, chairman & founder of Missile Defense Advocacy Alliance, says “It’s a needle in a haystack.”

Reports Friday that the U.S. military had downed an “unidentified object” near Alaska suggest that American skywatchers may already be adapting to the new challenge.

The Pentagon says the balloons are part of a Chinese surveillance program that has gone on for years and spanned the globe. The balloon that was recovered allegedly contained sensitive equipment that could be used [to listen to Americans’ communications](https://time.com/6254318/chinese-balloon-spy-equipment-antennas/) and pinpoint the location of those talking on the ground. Officials said they first spotted that one over Alaska, but a retroactive review picked up the other incursions, as well as evidence that balloons had floated over most regions of the Earth in recent years—including Southeast Asia, South and Central America, and Europe. 


China has dismissed allegations of espionage—instead claiming that the balloons are civilian craft for research; many experts have said [this is unlikely](https://time.com/6253002/chinese-balloon-weather-balloon-experts/) as the airship does not look like a weather balloon. 

The U.S. has spent decades investing billions of dollars into radar installations, satellite constellations, and other globe-spanning systems with the goal of detecting airborne threats. American airspace is monitored for fast-moving threats like missiles and planes primarily via radar. The technology works by sending out radio waves from antennae and listening for the waves to bounce back off an object. Based on the time it takes to return, an object’s speed, location and altitude can be determined. “You would think intuitively that you have this big round target that should be lighting up the radar like crazy but because of the nature of radar… that radiation can’t pass through certain materials means that this may not be the case,” says Ian Williams, deputy director of CSIS’s Missile Defense Project. 


Another issue is the temperature of the balloon itself. Missiles and aircraft are traveling at blistering speeds, so give off tremendous amounts of heat that can be detected at long-ranges. Not so, with slow-moving balloons in the stratosphere, Williams says. “They are not warm, typically. They kind of assume the temperature of the surrounding air for the most part; they don’t have an engine burning or anything like that,” he says. And at 60,000 feet—the altitude of the balloon the U.S. downed—the air is 70 degrees below zero Fahrenheit. 

If anything, the payload that the balloon is carrying may have a better chance of showing up, Williams says. Officials said they believe the balloon was equipped with large solar panels. But those objects can often be much smaller than the balloon itself, says Ellison.

Much of U.S. military spending is focused disproportionately on offense instead of defense, says Ellison, whose group advocates for spending more money on radars and interceptors designed to defend American airspace. “It’s about spending money the right way… it’s the Department of Offense over there; the American public has got to be protected.” 


One possible solution is for America to launch a fleet of its own unmanned balloons that would float off American coastlines equipped with sensors that could spot other incoming threats, Ellison says. These kinds of warning systems were used in Afghanistan to watch for enemy attacks and are now used on the Southern border to spot drug traffickers. 

Another way to improve air defense would be to centralize information from radar systems in the country, Williams says. Information from civilian system like the Federal Aviation Administration and National Oceanic and Atmospheric Administration does not automatically feed into military applications, he notes. 

That raw data could be useful for the military to filter and look for threats. “So we have all of these untapped reservoirs of airspace, situational awareness that we’re kind of leaving fallow,” Williams says.
