### 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.

Today, for the first time, the U.S. is making its own synthetic jewels. It has to. Reasons: 

\> Over 4,000 jewels —sapphires and rubies —are used as bearings in the electrical devices of a modern battleship’s engine room. Some 100 more jewels are in its fire-control mechanism. Another 100 are in the navigation instruments.

\> Over 100 jewels are used in the instrument panel of a big U.S. bomber. Others are in its bombsight. 

U.S. production of synthetic jewels has reached 1,000,000 karats\* a month, is going up fast. But some 10,000 U.S. workers must still be trained to cut and finish the raw jewels into the delicate, adamantine bearings which will resist wear, corrosion, friction. 

Five years ago a Massachusetts jewel cutter asked Army Ordnance officers if they were preparing a sure source of synthetic jewels for military instruments. He was told that the matter was too small to bother about. 

A year and a half ago OPM desperately called in all U.S. firms who might be able to manufacture jewels, urged them to have a try at it. For the Nazis had overrun Holland and France, bottled up Switzerland —the countries whence the U.S. formerly imported nearly all its synthetic jewels (as many as 100,000,000 a year). Only one company, Union Carbide & Carbon, volunteered to make synthetics. It alone produced the great volumes of hydrogen and oxygen which are essential in making them.

Tricky Boules. Like natural rubies and sapphires,\* synthetics are simply fused aluminum oxide. A tiny trace of chromium oxide makes jewels a ruby-red color, titanium oxide makes them sapphire-blue. Color is unimportant in industrial jewels except as it makes them easier to see, cut, assemble.

The powdery oxide is sifted slowly down into a flame formed by the union of the two gases. (An oxyacetylene flame is much too hot.) The powder drops and melts on the tip of a slowly moving stick. There, drop by drop, a single large crystal is formed. It is called a boule. Two hours are required to form a 200-karat boule the size & shape of a large bullet.

Simple in principle, this process is maddeningly tricky to control. Biggest problems are maintaining: 1) absolute purity of the powder; 2) its even flow to the flame; 3) a constant temperature. For over a year Union’s scientists fussed and fretted until a steady output of boules was achieved last month. This week Union is turning out all the boules the U.S. needs, thinks it can meet the rising demand singlehanded, although several other firms are now preparing to enter the field.

Apprentices Wanted. The uncut boules are shipped to U.S. jewelers to be split, sawed, cut, drilled, polished for use as bearings. This stage remains a serious bottleneck. Reason: jewel cutting in the U.S. involves more handwork than in Europe, where it is a highly mechanized art. So far the best apprentice jewel cutters have been nimble-fingered seamstresses. Grumbled a master jewel cutter last week: “We have been called upon to do a staggering job without having time to develop the machine methods it took the Swiss 100 years to develop.”

\* Weight of the average engagement-ring diamond: one-half to one-fourth karat. 

\* Natural and synthetic stones are chemically identical. Differences can be detected only with a microscope. If anything, the synthetics are a little better, since they contain fewer flaws.
