### 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.

Feb 23, 2017 9:25 PM UTC

Nearly 200 children and adults were at the [St. Paul Jewish Community Center ](https://www.stpauljcc.org/)in Minnesota — which offers swim lessons, community lectures and preschool classes — when the phone rang with a bomb threat on Monday morning. Students quickly evacuated to a nearby fire station, police officers swept the building and the center re-opened after no bombs were found. Days later, no one has been arrested.

“There’s very little evidence on which to move forward,” said Steve Linders, a spokesman for the St. Paul Police Department. He said it’s not yet clear what phone number or device was used to make the threat.

The case illustrates the challenges faced by law enforcement officials and hate crime experts working to combat a wave of recent anti-Semitic incidents across the country.

“Statistically, most of them are hoaxes. Realistically, you have to handle every one as if it’s the real deal,” said James Mulvaney, an adjunct professor at John Jay College of Criminal Justice who previously worked with the New York Police Department’s hate crimes task force.

“The duty of a terrorist is to terrorize, and you can terrorize a community without actually causing damage but by just causing unrest,” Mulvaney said. “Any threats against these places is an act of terror because it scares the heck out of people — and it scares the heck out of people who have a history of being victimized.”


There have been nearly 70 bomb threats at 53 Jewish Community Centers (JCCs) in the U.S. and Canada so far this year, according to the JCC Association of North America. Although it’s [difficult to quantify](http://bigstory.ap.org/article/0f03d4c012094f5aa3e56ceb3ac1bf15/evidence-rising-anti-semitism-data-mostly-elusive), civil rights experts see those threats as part of a spike in [racist and anti-Semitic incidents](http://time.com/4569129/racist-anti-semitic-incidents-donald-trump/) since the presidential election.

The Southern Poverty Law Center counted 1,094 bias-related incidents in the month following the election. But the center, which has long [tracked hate groups](http://time.com/4671800/hate-groups-on-the-rise/), has no way of comparing that figure to previous months because it only began tracking hate incidents after the election, when it was flooded with an “alarming” number of reports about racist and anti-Semitic incidents.

The Anti-Defamation League does not release its annual audit of hate incidents until all reports can be vetted, but the organization said it has been receiving more reports than usual this year.

More than 150 members of Congress on Wednesday [sent a letter](http://stephaniemurphy.house.gov/news/documentsingle.aspx?DocumentID=41) to the Department of Homeland Security, the Department of Justice and the FBI, urging authorities to “swiftly” investigate recent threats and prosecute the perpetrators. The FBI has said it is investigating “possible civil rights violations in connection with threats to Jewish Community Centers across the country” and declined to comment further.


“The reason they’re so difficult is, indeed, because this is not 1980 where someone can just do a quick look and find where the call emanated from,” said Oren Segal, director of the ADL’s Center on Extremism, noting that the internet and other forms of technology have made it easier for perpetrators to remain hidden.

He said the ADL, whose headquarters were targeted with a bomb threat on Wednesday, is working with the FBI to investigate the source.

“They’re extremely difficult to investigate, again, because they are perpetrated from a distance. The offender tends to remain anonymous, and hate crimes are difficult to identify in the first place,” said Jack Levin, a hate crimes expert and co-director of the [Brudnick Center on Violence and Conflict ](http://www.northeastern.edu/brudnickcenter/)at Northeastern University.

“Even if they never find the perpetrator, there are solutions that go beyond law enforcement,” Levin said, noting that the community and political leaders can offer support to those affected. He believes hate crime laws are also important because they can be a deterrent.

“It’s kind of like asking the impossible: How do you stop racism? If I knew the answer to the question — if anyone knew the answer to that question — the world would be a much better place,” said Ryan Lenz, editor of the Southern Poverty Law Center’s Hatewatch blog.

Lenz said President Donald Trump’s [denunciation of anti-Semitism](http://time.com/4676837/donald-trump-anti-semitism-threats/?iid=sr-link1) this week — and [Vice President Mike Pence’s](http://time.com/4679604/mike-pence-condemns-cemetery-vandalism/) visit to a [vandalized Jewish cemetery](http://time.com/4679048/jewish-cemetery-vandalism-muslims-fundraiser/) in St. Louis — were important steps. But he thinks the threats deserve more attention.

“I think it’s important to recognize that something changed in this country after the election,” Lenz said. “This without a doubt is a new development.”
