### 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.

As an organ is to a piano, so is a carillon to an ordinary set of bells. Numbering at least 24 (covering two octaves), the bells of a carillon are tuned with the sharps & flats of the chromatic scale, are struck by hammers like piano keys. A chime or peal of church bells, from four to twelve in number, is tuned in the simple diatonic scale and the bells swing freely, emitting their not-always-melodious tones when struck by their clappers. In carillons, the biggest and the smallest bells are the trickiest to cast and tune. Ranked according to the size of their big bass bells, the world’s best carillons, all made in England, are all in North America, the largest being the 72-bell carillon of Manhattan’s Rockefeller-built Riverside Church, whose 20-ton bass bell is the largest tuned bell extant.\* Others: the 72 bells of the University of Chicago Chapel; the Baird Carillon at the University of Michigan; the Bok Carillon in Mountain Lake, Fla.; the 53 bells of the Peace Tower of Canada’s Parliament Building in Ottawa. Last week small Alfred University in Alfred, N. Y. inaugurated a carillon of 35 bells which it claimed was the oldest in North America. 

Good bells neither improve nor deteriorate with age. But bell founding reached its height in the Low Countries of Europe by the 18th Century, was thereafter a lost art until British bellmakers began rediscovering it about 40 years ago. When alumni and faculty members of Alfred University resolved to spend some $10,000 on a memorial carillon for President Emeritus Boothe Colwell Davis, they instructed a bell founding firm of Brussels, Michaux & Michaels, to buy 35 old bells rather than cast new ones, which would cost somewhat more. Agents of Michaux & Michaels bought the bells in municipal halls, churches and chateaux of Belgium, Holland, northern France. Many of the owners parted with their bells because they feared they might be seized or destroyed in the next war. 

Alfred’s biggest bell, weighing about a half ton, is also its oldest, cast in 1674 by Pieter Hemony of Amsterdam, ablest bell founder of his time. The youngest bell in the collection was cast in 1784 by another famed bellman, Van den Gheyn of Malines. The 35 assorted bells were assembled and tuned—by scraping metal from the lower “lip” and the inner surface—by Jef Denyn, director of the Belgian National School of the Carillon. The carillon, housed temporarily in a wooden tower on the Alfred campus, was played publicly for the first time last week by Henry S. Wesson of Navasota, Tex., a carillonneur who studied with Director Denyn and, as U. S. representative of Michaux & Michaels, installed a carillon they cast for the Belgian Village at the Chicago Century of Progress Exposition. 

Chimes of bells are limited to simple hymns and folk tunes, or unmelodic “change ringing” which is fairly common in the U. S.† The musical literature of the carillon is larger, although it, too, has its limitations. One of these is that each bell has four or more separate “partials” or overtones in addition to its fundamental note, and when these are not all in tune with each other as well as with those of other bells, a prodigious jangling results. Thus a carillonneur must often rearrange a composition to allow for discords in his family of bells. Nevertheless, on the ancient bells of Alfred last week, Carillonneur Wesson performed a remarkable variety of tunes, ranging from Hail to Thee, Alfred to two movements from a Sonata for Carillon by Teinmerinaus. 

\*World’s largest bell, which cracked in casting and hence is untuned, is Russia’s Tsar Kolokol (Tsar of Bells), made in 1733, 19 ft. high and weighing 440,000 lb. 

†”Changes” are rung on a number of bells by a number of ringers, in mathematical sequence. This strenuous pastime, popular in England (see Dorothy Sayers’ The Nine Tailors), involves varying the order of pealing bells so that no one succession of notes is repeated during the lengthy operation. In 1922 the Oxford Diocesan Guild and the Ancient Society of Youths rang 21,363 different changes at the rate of 28 a minute, a record.
