### 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.

Denver Housewife Jeannie Lancaster suspected that something was wrong with her son a few months after his birth. “He was always fussy and would never cuddle,” she remembers. “When I would go to pick him up, he would arch away.” By the time he was one, he had acquired the alarming habit of banging his head against the wall, and when he began to talk, he repeated the same sound or word over and over again. Says Lancaster, “I kept asking myself, ‘What am I doing wrong?’ ” Professional counselors offered conflicting views. A pediatrician thought the boy might be autistic. School officials said he was emotionally disturbed. Further testing indicated he was mildly retarded.

It was only after Lancaster had given birth to a second son who showed some of the same mysterious symptoms that a family doctor began to suspect the cause. He had just returned from a medical seminar on a newly recognized disorder called Fragile X syndrome, which results from a weakness in the structure of the X sex chromosome (one of the 46 chromosomes — complex molecules containing long segments of DNA — in the nucleus of the human cell). The behavior of the Lancaster children seemed to fit the patterns described at the meeting, and tests at Denver’s Children’s Hospital soon confirmed that they both had the defective chromosome.

Virtually unknown to doctors five years ago, Fragile X has come to be recognized as a leading cause of mental retardation among newborns in the U.S., second only to Down’s syndrome. It produces disabilities ranging from learning difficulties, especially in math, to mental retardation, often accompanied by such benign physical abnormalities as oversize ears, an elongated forehead, enlarged testes and double-jointedness. Recent research also suggests that Fragile X may be responsible for one out of ten cases of autism, a mysterious condition characterized by extreme withdrawal and refusal to communicate. At one time, autism was often blamed on cold, unfeeling parents.

Doctors diagnose Fragile X by using a microscope to examine X chromosomes isolated from white blood cells. The defective site is often clearly visible at the end of one of the chromosome’s arms. Last year a more accurate diagnostic test was devised by Geneticist W. Ted Brown, of the New York State Institute for Basic Research in Developmental Disabilities (IBR) on Staten Island. Brown’s team uses a technique in which snippets of DNA taken from the X chromosomes of people suspected of having the condition are compared with snippets from their normal relatives.

Because the defective site is on the X chromosome, females (who are born with two Xs, one inherited from each parent) are less often affected by the syndrome; their normal X chromosome can mask the effects of the faulty one. But males, who have one X and one Y sex chromosome, have no such backup and are therefore more susceptible. Still, for reasons that baffle scientists, not all females are protected, and some males are spared. “About 20% of males who inherit the gene are unaffected carriers, and about a third of all females who are carriers are affected,” says Pediatrician Randi Hagerman, of Children’s Hospital. “It’s a crazy inheritance pattern.”

No one understands exactly how or why the Fragile X mutation affects the brain. Autopsy studies by IBR Director Henry Wisniewski and his colleagues have shown that the number of connections, or synapses, between brain cells in autistic children with Fragile X syndrome is unusually low and the connections that do exist are not well developed. “In normal adults the connections are short and stubby,” says Brown. “In Fragile X, they are longer and thinner, as in newborns. It’s as if a stage of development hadn’t been achieved. They haven’t made the normal contacts between cells.”

Realizing that Fragile X is more common than previously believed, doctors have begun to recommend that all children with unexplained cases of mental retardation be tested for the syndrome. At the very least, they say, such examination will reveal if the child’s condition is hereditary and will enable parents to evaluate the risk of having another affected child. Fragile X can also be diagnosed prenatally by means of amniocentesis. But doctors cannot yet determine whether the fetus will be affected or simply be a carrier.

However the syndrome is discovered, the first few years of the infant’s life are crucial. The greatest improvement among slow-learning or mentally retarded Fragile X children occurs when therapy begins early. Both Lancaster boys have undergone intensive speech, language, balance and coordination training, along with a more controversial treatment with the vitamin folic acid. The younger boy, now 8, seems to be calmer and more attentive than his ten-year-old brother, possibly because his treatment began earlier in life. “We’ve seen a lot of improvement,” says Lancaster. “The boys are both in the Cub Scouts. I know there are people out there who are struggling as we did. Early intervention makes a big difference.”
