### 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.

The young Theodore Roosevelt did notÂ strike most people as promising enough to become one of the nation’s greatest Presidents. His august Knickerbocker family had grown rich from generations of shrewd investments in real estate, banking, glass importing and even hardware. But in his youth–and for that matter in his adulthood–T.R. showed very little interest in adding to the family fortune. When Roosevelt was a toddler, his asthma began to overshadow everything he did. As he grew, Theodore was too “delicate” for school–until Harvard he was educated at home–and too weak to stand up to other boys. On doctor’s orders his father Theodore Sr.–called Thee by everyone in the family–and his mother Martha, called Mittie, rushed him to seashore resorts one day and mountain cabins the next in search of air to help him breathe. The sickly boy seemed unlikely to survive into manhood or amount to much if he did.

But Roosevelt’s childhood weakness would turn out to be the provocation for the ferociously robust man he became. At about the time Theodore reached the end of boyhood, Thee, whom young T.R. adored, set off a crisis in their relationship. He insisted on making his favorite child into a strong man by directing him to embrace a life of vigorous exercise. He told him with characteristic sternness to throw off his invalidism by force of will. He ordered the boy to “make your own body.” According to Theodore’s sister, Theodore “resolved to make himself strong,” to turn his back on his “nervous and timid” childhood and embrace manhood. The cure would come by way of sports and outdoor activity, mountains to be climbed and harsh weather to be endured.

From that day forward, T.R. became a fierce champion of what he called the “strenuous life,” a self-imposed struggle to live with vigor and determination. He boxed and pulled at weight machines, and his chest expanded along with his capacity to breathe. To conquer his fragility he began, wrote a friend, “constantly forcing himself to do the difficult and even dangerous thing.” Years later, T.R. wrote in his autobiography that his life changed forever because he set fearlessness before him “as an ideal” that by dogged practice he achieved. Advised that he had a bad heart and shouldn’t climb stairs, the 22-year-old T.R. ascended the Matterhorn.

His self-making had costs. Throughout his life he repeatedly injured himself, even sustaining a boxing injury when he was 45 that on top of a cataract cost him the sight in his left eye. Obsessively seeking strength through exercise and adventure, he developed an equally overdone hatred for sissies, “cripples and consumptives,” for anyone who could not measure up physically or who reminded him of his childhood shortcomings. He even told his sons he’d rather see them dead than have them grow up to be weaklings. He could never admit to frailty in himself. That was one reason his charge up Kettle Hill in the Battle of San Juan Heights with the Rough Riders, the volunteer cavalry unit he organized to fight in Cuba during the Spanish-American War, was so important to him. It proved to the world–and himself–that Roosevelt, a man who could talk very admiringly about war, had the strength and courage to fight in one. Although all his life, even when he was President, he continued to suffer on occasion from asthma he did not want the public to know of his illnesses. It didn’t fit his self-image.

There was another dimension of the young Roosevelt’s determined embrace of vigor: his wholehearted encounter with nature, sometimes as a naturalist, sometimes as a hunter. It shaped his life and his enduring image. Nature provided the setting for his struggle to make himself strong, and it opened up a world of scientific discovery at the same time. Roosevelt always remembered the day during his boyhood when he was walking up Broadway and spotted a dead seal on display in a market. Fascinated by the animal, he went back to see it again and again and eventually took its skull home to study. It was the first of countless natural-history projects.

Roosevelt began to collect animal specimens, including fireflies and squirrels. He filled his notebooks with drawings and life histories of animals and insects, such as the common black ant, and then read Darwin and Huxley, who helped him ponder how Homo sapiens coexisted with the so-called lesser creatures. When the American Museum of Natural History unpacked 2,200 mounted creatures from the collection of the Verreaux brothers, French naturalists, the unabashed young Theodore donated his own mounted menagerie–a bat and 12 mice.

Delighted to see that his son loved nature, Thee took him camping and encouraged his interest in biology and dissection. Mittie was not so enthusiastic. Dead-animal stink and the reeking chemicals used to preserve hides upset the decorum of her parlor. But nature and the science of nature were the solace of Roosevelt’s invalid childhood, a refuge where he could achieve intellectual mastery at a young age. Under his father’s loving tutelage, T.R. fashioned himself into a naturalist whose specimens can be viewed in museums today; scientists later welcomed him as an equal into their debates about how to classify species.

When Thee died of cancer at age 46, Theodore, then 19, was overcome by grief, but within a year he fell in love with a Brahmin beauty named Alice Lee, who found his stories of hunting in the Maine woods charming. Just before they wed in the fall of 1880, he went West to hunt with his brother Elliott. He hoped life in a saddle and breathing the open air all day would build up his strength once more. On the trail, he fell in love again, this time with the American West.

By the time he graduated from Harvard, T.R. had made himself the most experienced outdoorsman in a class filled with the sons of wealth and comfort. And his fierce determination to make his life count for something larger than his own interests sent him into writing and politics and the study of history. Indeed, even as he settled into married life with Alice and attended Columbia Law School, T.R. turned back to nature. He eventually bought two ranches in the Dakota Territory, where he could raise cattle to sell to the Eastern markets and at the same time retreat for health-giving hunts when his life in the East permitted.

Thus began the pattern of his adulthood, to work fiercely in the East for the causes he cared about, writing and politicking, until he was so weary that he headed West to regain his health. Nature replenished him when he was depleted. When Alice died in February 1884, shortly after giving birth to a daughter who would share her name, T.R. headed to the Dakotas to find solace for his grief.

When Roosevelt became President in 1901, he took his love of nature with him to the White House. When the strain of the job weighed on him, he stepped outside to watch the spring birds migrating. He identified the blackpoll warblers perched in the elms outside the Oval Office. And he kept a list of his sightings. Anytime he yearned for the strenuous life outside the White House, Roosevelt cheerfully dragged ambassadors and small boys to climb rock faces and ford streams in Rock Creek Park. Few could keep up with him.

In a way, President Roosevelt regarded the nation’s trees and open land and animal inhabitants as prime constituencies whose interests he must serve. His dear friend forester Gifford Pinchot joined him in warning the public that the natural resources of the U.S. were not inexhaustible, that a timber famine was imminent and that coal, iron, oil and gas would run out someday. Congressional leaders didn’t want to hear about game or tree protection or the resource needs of future generations. Roosevelt took advantage of what he called the “bully pulpit” of the presidency to educate voters and legislators about the need for laws to protect natural resources.

In the spring of 1903, Roosevelt used a trip out West to dramatize his commitment to preserving wild places. With the nature writer John Burroughs he followed birdsongs in Yellowstone Park, then rode mules into Yosemite with John Muir, the great preservationist and founder of the Sierra Club. Roosevelt and Muir slept under the stars and were covered overnight by a blanket of snow. T.R.’s journey from asthmatic ornithologist to hearty rancher turned President proved that a silver-spoon birth does not have to prevent a man from developing, over time, a broad vision and a rare kind of political gumption. All he required was a chance to make himself a new man by embracing nature and its creatures with his whole heart.
