### 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.

Shortly after Luigi Mangione [pleaded guilty](https://time.com/article/2026/08/14/luigi-mangione-guilty-plea-federal-case-unitedhealthcare-brian-thompson/) on Friday to two federal charges in connection with the [fatal 2024 shooting](https://time.com/7200059/unitedhealthcare-ceo-brian-thompson-fatal-shooting/) of UnitedHealthcare CEO Brian Thompson, his lawyers filed a motion arguing that the New York state case against him should be dismissed because of a legal principle known as double jeopardy.

Mangione, who was arrested in December 2024 five days after Thompson was killed in New York City, admitted in federal court on Friday to shooting the healthcare executive.

“I shot Mr. Thompson in Manhattan,” he told the judge, according to the New York _Times._

**Read More:** [_Luigi Mangione Pleads Guilty to Federal Charges in UnitedHealthcare CEO’s Fatal Shooting_](https://time.com/article/2026/08/14/luigi-mangione-guilty-plea-federal-case-unitedhealthcare-brian-thompson/)

Mangione wasn’t facing murder charges in the federal case against him; rather, he faced two stalking charges in connection with the shooting, both of which he pleaded guilty to. Each of the charges carries a possible life sentence. He is set to be sentenced in federal court on Dec. 18.

In New York state court, meanwhile, he has been charged with multiple counts, including second-degree murder—all of which he has pleaded not guilty to.

His state trial was set to begin on Sept. 8, but has effectively been pushed back after the judge overseeing the case said the Manhattan District Attorney's Office has to respond to the motion filed by Mangione’s lawyers by Oct. 9\. The next hearing for the state case is now set for Dec. 10.


Here’s what to know about double jeopardy, and what Mangione’s lawyers argued in their recent filing calling for the state charges to be dismissed.

## What is double jeopardy?

The Fifth Amendment, which lays out several key legal rights, includes a clause establishing a constitutional protection known as double jeopardy: “nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb.” In other words, an individual can’t be prosecuted for the same crime twice.

In the past, the U.S. Supreme Court has [ruled](https://www.nytimes.com/2019/06/17/us/politics/supreme-court-double-jeopardy.html) that it is possible for a person to be prosecuted for the same conduct in both federal and state court because the federal and state governments are independent entities. But the state of New York offers defendants strong double jeopardy protections; in New York, a prior conviction—either through a guilty plea or a guilty verdict after a trial—for the same offense typically triggers double jeopardy.


## Why are Mangione’s lawyers arguing that the state case should be dropped?

Mangione previously pleaded not guilty to all the federal and state charges levied against him, and his lawyers have not publicly disclosed why the 28-year-old chose to change his plea in the federal case. But after the hearing on Friday, his lawyers announced that they had filed the motion claiming double jeopardy.

“It was a single tragic event, yet he’s being prosecuted twice for the same conduct,” Karen Friedman Agnifilo, one of Mangione’s lawyers, told reporters on Friday.

In the [motion](https://www.nycourts.gov/LegacyPDFS/press/pdfs/2026.08.14%20-%20Double%20Jeopardy%20Motion%20-%20FILED%5F3862.pdf), his lawyers argue that Mangione’s federal guilty plea “‘terminates’ the federal proceeding” and is now considered to be a “previous prosecution,” meaning that the New York state case would be a “second prosecution,” triggering double jeopardy.

His lawyers also allege in the filing that the Justice Department and Manhattan District Attorney’s Office coordinated their cases against Mangione so that the state would go to trial first“to ensure dual successive prosecutions, in order to attempt to avoid double jeopardy protections.” They allege that this effort was meant “to maximize the punitive effectiveness of the two cases at the expense of Mr. Mangione,” which in turn “undercuts the separate sovereign rationale of the federal double jeopardy jurisprudence.”

“Simply put, if two sovereigns agree on a plan to prosecute two criminal cases charging the same exact criminal event—in this case a single murder—so as to maximize each of their chances of gaining convictions and achieving the greatest degree of punishment, they are acting as a single sovereign, one prosecuting the same man twice for the same event,” they wrote.

The Manhattan District Attorney’s Office said in a [statement shared on X](https://x.com/ManhattanDA/status/2088305242509078849) on Friday that it “has been tirelessly preparing to pursue a trial conviction” in the case since December 2024 and that it was prepared to proceed with its case.

“While federal sentencing is pending, we are prepared to litigate the defense motions,” the office said. “The Manhattan D.A.’s Office remains committed to seeking justice for Mr. Thompson and his family.”
