### 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.

Invitation Command

Scheduled for next week at Manhattan’s Hotel Chatham was the beginning of the most advertised, most bitter, most ambitious bridge match ever held. Manhattan card sharps could recall no card contest of any kind quite like it. Though bridge is a four-handed game, this match will be essentially between Sidney S. Lenz, long-recognized bridge authority and Ely Culbertson, young, brilliant, individualistic and—to conservatives—extremely unpopular contract expert. The match was arranged after months of acrimonious wrangling, conducted with due regard to the publicity value of a grudge fight, but also representing a basic disagreement as to how contract hands should be bid. 

The bridge world is currently divided between followers of the Lenz (a version of the Official) system and the Culbertson (or approach-forcing) system of play. Virtually all other bridge experts have joined with Mr. Lenz in approving the Official System, which was adopted largely to eliminate confusion during contract’s experimental period. Mr. Culbertson, however, flatly refused to toss his system into the common pot. He has bitterly attacked the Official System and Mr. Lenz as one of its prime movers. 

The Lenz-Culbertson test match was finally fixed at 150 rubbers. Mr. Culbertson will play a portion of the match with chic Mrs. Culbertson as his partner. His alternate partners will be Baron Waldemar von Zedtwitz and Theodore A. Lightner. Mr. Lenz will play the entire match paired with Oswald Jacoby, member of the team which recently won the Vanderbilt Cup. Cocky Mr. Culbertson has backed himself with a $5,000 wager against $1,000 on the Lenz side. Culbertson winnings are promised to the New York Infirmary for Women and Children; Lenz winnings to the Unemployed. 

The Lenz and Culbertson systems, one of which will supposedly be proven superior, differ chiefly in that when Lenz makes an opening bid of two in any suit, he invites (without compelling) his partner to make an answering bid. Culbertson’s initial bid of two is a command for partner to respond, no matter how weak partner’s hand may be. Here is what each expert feels he must have in his hand for opening suit bids of one, two or three: Bid Lenz Culbertson1 2½ tricks 2½ tricks No difference 2 3 or 3½ tricks 5 or 5½tricks Culbertson force 3 or 10 tricks 8 tricks Lenz force 

Advantage of the Lenz system is that there are many hands too strong for a bid of one and not strong enough for a forcing bid. The Lenz two-bid works well with this type of hand, since it encourages partner to reply if he has a little help but does not compel him to reply even when he has no help. To bid two, Mr. Culbertson’s hand must be so strong that if partner replies with two no-trumps (standard indication of a “bust”), Mr. Culbertson can either let the declaration stand or take it out with a bid of three in some suit. Opponents of the Culbertson system maintain that he has no way of indicating a hand that is one trick or even two-tricks stronger than the requirements for a one-bid. Opponents of the Official system maintain that this very fact gives added merit to the Culbertson system: the opposing side does not know the exact strength of the bidder’s hand. 

A less vital difference in the two systems lies in Culbertson’s strong preference for an opening suit bid as opposed to an opening no-trump bid. In estimating the trick-taking possibilities of high cards, Culbertson counts ace. king and queen in one suit as two tricks, Lenz counts the same holding as three. 

It is doubtful whether even 150 rubbers will prove anything as to comparative merits, since the result must also depend upon the distribution of the cards, the skill of the players. Both Culbertson and Lenz will get a great deal of advertising, and all bridge teachers will profit by having two systems to teach their pupils. Public interest in the match may also assist contract to withstand the onslaught of back: gammon as a leading indoor sport.
