### 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.

Bloomberg — Airlines’ U.S. flight cancellations neared almost 1,800 for the Christmas weekend, disrupting travel on one of the busiest periods of the year as the omicron-fueled wave of Covid cases triggered air-crew shortages.

Saturday’s pullbacks erased at least 10% of the schedule at Delta Air Lines Inc., United Airlines Holdings Inc. and JetBlue Airways Corp., according to data tracker FlightAware.com. The cuts on Christmas Day in the U.S. totaled almost 900.

“Like many businesses and organizations, we have seen an increasing number of sick calls from omicron,” JetBlue spokesperson [Derek Dombrowski](https://www.linkedin.com/in/derek-shore-dombrowski-05969631/) said in an emailed statement. “Despite our best efforts, we’ve had to cancel a number of flights, and additional flight cancellations and other delays remain a possibility as we see more omicron community spread.”

Airlines’ tie-ups added to evidence of economic disruptions from the omicron variant, whose fast spread is causing havoc even though initial indications suggest that it causes less-severe illness than other Covid strains. Health-care systems are being squeezed by a lack of staff, and a U.S. Navy warship is stuck at Guantanamo Bay after a Covid outbreak on board.

The global tally of dropped flights exceeded 5,700 trips for Friday through Sunday, according to FlightAware. China Eastern had the most cancellations, and the most-affected airport was in the Chinese city of Xi’an, where the Beijing government cracked down under its Covid Zero policy after an outbreak.

Delta’s 539 cancellations for the holiday weekend led the U.S. industry, FlightAware data showed, closely followed by United, with 484 flights erased from its holiday itineraries. JetBlue had at least 201 flights canceled for the weekend, according to FlightAware.

The holidays are among the heaviest times for travel. The Transportation Security Administration was estimating Dec. 22 and 23 would be the busiest pre-Christmas travel dates nationally and locally, with Jan. 2 and 3 the most crowded for post-holiday travel.

Costumer-complaint messages piled up on the airlines’ Twitter feeds as passengers lamented the disruptions to their holiday weekend plans. Travelers denounced the flight delays, cancellations and missing luggage on social media.

“The nationwide spike in Omicron cases this week has had a direct impact on our flight crews and the people who run our operation,” said [Maddie King](https://www.linkedin.com/in/maddie-king-869202a4/), a spokesperson for United. “As a result, we’ve unfortunately had to cancel some flights and are notifying impacted customers in advance of them coming to the airport.”

[Globally,](https://www.bloomberg.com/news/articles/2021-12-24/china-punishes-local-officials-as-covid-still-spreads-in-xi-an) cancellations ranked among the highest at Xi’an Xianyang International Airport, in the western Chinese city where the government punished local officials for failing to curb an outbreak that led to the biggest lockdown since Covid emerged in Wuhan. Nearly a third of the flights departing from the airport were canceled Friday and Saturday, according to FlightAware.

Robert Mann, a former American Airlines executive who is now a consultant, said there are about 115,000 flights a day globally during a peak travel period such as Christmas.

“As for China, It’s not a very transparent market over there, and what we know there’s been a number of cities that have shut down, and as result that would be expected to impact air service dramatically.”


Elsewhere, British discounter EasyJet said it had canceled some flights between the U.K. and France and Germany for the rest of December, following the introduction of restrictions on U.K. travelers to those countries.
