### 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.

Adjustable accessories can be tailored to workers’body sizes 

O.K., lean way back in the chair. Rest your head and stretch out. Relax. Now get to work. 

Work? Yes, indeed. Ergonomic furniture design—that is, designing for the human frame—is confirming what some people suspected long ago: the mind seems to work better when the body is firmly and comfortably supported in a reclining position. Thomas Jefferson liked to read and write while taking his ease on a specially adapted chaise longue. Mark Twain and Winston Churchill often worked lying back, their heads supported, facing their books or writing pads at eye level. In such a position, they were able to prevent many a pain in the neck. 

The trouble with some chairs today, says Industrial Designer Niels Diffrient, is that they “look as though the designer never saw a human body.” Diffrient has come up with an innovative, adjustable lounge chair engineered on anatomic rather than aesthetic principles. The top of a radically new furniture line designed by Diffrient for computer-age offices, the chair will be introduced on the market next spring by the U.S. manufacturer SunarHauserman. Probable price, including accessories: around $3,500\. 

Diffrient’s furniture system consists of a number of components that can be put together to suit the individual tasks, comfort and predilections of every worker in today’s automated office. Surfaces can be lifted or lowered, tilted or joined every which way; adjustable video supports, telephone holders, In and Out baskets, bookshelves, copyholders and other accessories can be readily attached. Says Diffrient: “We set out to design an office furniture system that fits everyone who uses it—from the shortest woman to the tallest man—like their clothes or shoes.” 

The lounge chair, which Diffrient named for Jefferson, has none of the sleek elegance of the chaise longues designed by Mies van der Rohe or Le Corbusier, nor the coziness of the Eames lounge chair. But then, none of them is adjustable and completely comfortable. In designing his Jefferson chair, Diffrient set aside all questions of form and tried to think like an engineer. After much trial and error, he arrived at a design that suspends the chair on a central axis that pivots much as the body does at the waist and hips. The pivoting motion is controlled by a gas-cylinder mechanism activated from the armrest. The headrest supports the neck at the underside of the cranium. The elbows repose without being pushed up. 

Adding the separate ottoman or footrest makes the chair blissfully relaxing. Adding the “task accessories” for reading and writing makes it a marvelously efficient work station. The lamp and a small round side table for a telephone, ashtray, vase, drink or whatnot are supported by a freestanding column. Another column supports a television set or computer monitor, as well as a cantilevered, tilting table that can hold a computer keyboard or serve as a writing surface. The columns can be placed anywhere. The computer disc drive goes in an upright console next to the chair. Diffrient maintains that “the energy you save by reducing the strain of holding yourself up and worrying about whether your back aches or your arms hurt is directly converted to the work at hand.” 

A lean, silver-haired Mississippian, Diffrient, 55, has always disdained the merely stylish, devoting most of his professional life to accommodating what he calls the “human factor” in the tools and furnishings of our high-tech civilization. He started as a painter, but switched to industrial design while studying at the famed Cranbrook Academy of Art, near Detroit. During that time he apprenticed with Architect-Designer Eero Saarinen, making drawings and models for office chairs. He eventually won acclaim for his own chairs but is just as proud of the tractors, lift trucks and airplane interiors he helped create during 25 years with Henry Dreyfuss Associates, a leading industrial-design firm. At Dreyfuss, he also helped develop an encyclopedic series of guidebooks for designers called Humanscale, which provides data about the dimensions and movements of the human body. 

Diffrient’s chair prompts visionary speculations about the office of the future. Perhaps the executive desk will become obsolete except as a status symbol to sit behind, not to write on. And what of the conference room of tomorrow? How about a congenial grouping of Jefferson lounge chairs, their occupants all watching the displays presentedon their individual monitors? —By Wolf Von Eckardt
