### 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.

If a baby is born too deaf to hear, he cannot imitate speech and therefore cannot learn to talk. At least one baby in every thousand is born with no apparent capacity for hearing; he is “deaf and dumb.” But so-called congenital deaf-mutism is actually a misnomer because inborn defects of the vocal cords that make speech impossible are almost unknown. The real trouble is in the hearing mechanism. The vocal difficulty is almost inevitable because children judged to be beyond the help of any hearing aid are often sent to special schools where the emphasis may be on lip reading and sign language. Their own voices may never develop intelligible sounds, so they may fit their lives to their handicap and relegate themselves to a deaf-mute ghetto. 

But not if the born-deaf baby is lucky enough to land in either of two special schools in France, both run by Dr. Guy Perdoncini, 50, who has his schools in Villefranche near Nice, and at La Norville outside Paris. Otologists have long known that even the “totally” deaf child usually has a vestige of hearing—mainly for the rumbling, deep-bass tones, which carry more energy than thin, high notes. Dr. Perdoncini was convinced that even this minimal capacity could be developed so that the child could learn near-normal speech. And in finding ways to prove his theory, he has made himself a world leader in the treatment and education of the congenitally deaf. 

No Lip Reading. Dr. Perdoncini believes in getting his pupils started young, often with preliminary training at home when they are only a year old. To make lip reading impossible, he and his teachers cover their mouths with loose cloth masks. At three or four, the child goes to school full time. 

The little freshman in a Perdoncini school is fitted with earphones into which a bass tone is fed at a volume that would be ear-shattering to a person with normal hearing. At first the sensation means nothing to the student. But he also gets a visual signal; a light flashes on along with the sound, and the teacher gestures with her hand to show that she has heard and seen. The youngster copies her and gestures with his hand to show that he, too, has heard and seen. Soon he learns to recognize the sound alone, and the visual cue is abandoned. Next he learns that sounds may be long or short, and with building blocks of different lengths he tells teacher which is which. 

After a few weeks or months, depending on his own rate of advance, the child enters a world in which some sounds are high-pitched, some low. With patiently encouraged practice he learns to hear a widening range of frequencies. Tones that came through to him so weakly that once they stirred no response at all now turn into recognizable sounds. Soon the child is fitted with a microphone, and when he makes a noise with his own vocal cords, he sees a light flash on and the teacher signals receipt of this message with her hand. 

Inevitably, many a child begins by pitching his own vocal efforts too high or too low, too loud or too soft. Dr. Perdoncini and his twelve teachers are implacable about correcting a pupil’s pitch until it is acceptable. The child who is born deaf may need only a year to learn how to pronounce the names of foods, toys or friends. Words for abstract ideas take longer. 

Catching Up. Slowly, as they learn that the sounds they are imitating carry specific meanings, the kids build up a practical vocabulary. Then, equipped with powerful hearing aids, they are graduated from Dr. Perdoncini’s schools around age ten. They are not cured—they are still deaf—but now they can make use of the small auditory sense they have. They have been habilitated to the stage where they can go to ordinary schools and face the task of catching up to normal children. At the same time, without skill in lip reading or sign language, they adapt themselves to the society of those for whom talking is as natural as breathing. 

Dr. Perdoncini, a modest Rivieran of Swiss-Italian extraction, does not claim to have discovered or invented anything —only to have developed a method that, when pursued with enough patience and determination, gets results. He is understandably pleased that his method is finally being adopted by special schools in Italy, Spain, Sweden, Switzerland and Lebanon. One such school has begun operating in Quebec, and four Canadian teachers are currently in Villefranche for a years study of Dr. Perdoncini’s method.
