### 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, the border between the United States and Mexico is clearly delineated. But it was far hazier in 1821, when Mexico gained its independence from Spain. Then, the boundary was vast and never formally surveyed, stretching from modern day Oregon to Louisiana. California, Texas and most of the current U.S. southwest were part of Mexico.

In July, David Taylor, a multimedia artist and professor at the University of Arizona, and Mexican visual artist Marcos Ramirez, known as ERRE, set out to mark this border for the first time in a multi-disciplinary project titled [_Delimitations_](http://delimitationsblog.tumblr.com/). “\[This is\] about the transitory nature and ephemerality of borders,” says Taylor. “We live with borders all the time and we depend on their permanence. But, in fact, history does not support them as static phenomena, they move around all the time.”

Taylor and Ramirez traveled in a van along the 1821 border, from Brookings, Ore. to Port Arthur, Tex., marking coordinates with 47 obelisk-shaped monuments forged out of galvanized steel – similar to the 276 obelisks that mark the contemporary US-Mexico border, which Taylor previously documented in [_Working the Line_](http://www.dtaylorphoto.com/portfolio.cfm?nK=7752&nS=0&i=145961#0).

![Marcos Ramirez ERRE drives the <i>Delimitations</i> van in front of the Nevada Museum of Art. ](https://static.time.com/v3/assets/bltea6093859af6183b/blt653e661ae6ae7cd8/6986904113c79fe6981922cb/david-taylor-marcos-ramirez-erre-immigration-borders-van.jpg?branch=production&width=3840&quality=75&auto=webp)

“One thing that we found really fascinating,” Taylor says, “was going to places like Medicine Bow, Wyoming, which would have been a border town. People had no concept of the fact that Mexico stretched that far north. They don’t realize that literally 2,400 miles of border moved far enough south that what is now parts of Wyoming and Oklahoma and Colorado and all of California, Utah, Nevada, Texas, New Mexico, and Arizona was all Mexico.”


The project examines historical borders and calls attention to their shifting nature, not just in concept but also in practice. The steel monuments aren’t meant to be permanent. They can shift location through human or natural intervention, mirroring the characteristics of borderlines throughout the world. Taylor and Ramirez recorded the GPS coordinates of the monuments so that the entire “border” they created can be viewed on [Google Earth](http://delimitationsblog.tumblr.com/post/94199739711/coordinates-and-waypoints). Now, the map shows an almost perfect version of the 1821 U.S.-Mexico border. But over time it will erode.

The geographic erosion echoes a cultural fusion. There are many ethnic Mexicans, living in areas that used to be Mexican territory and are now part of the U.S., and who have lived on the same land for generations. However, these U.S. citizens can, at times, face discrimination because of their heritage.

“We’re thinking about the tangibility and permeability of borders while we were doing the project,” Taylor says. “And there’s real life drama and tragedy unfolding on the contemporary border. The idea that there is another history that needs to be acknowledged so we can grapple with the situations that we are considering today, that has a real tangible value.”


Taylor stresses that one of the most important aspects of this project was that he and Ramirez collaborated together as a “bi-national committee,” contributing insight and influence from both sides of the border. Taylor recalls his counterpart saying profoundly: “the Mexican-American war was a wound, but since the border was never surveyed, there’s no scar.”

“We \[wanted to do\] something that would prompt people to really think about what we were doing,” Taylor says. “And the people that we met really rose to the occasion. Possibly we need to look other places for having a thoughtful conversation about these \[immigration\] issues. Maybe the folks who have the bully pulpit aren’t the best people to be doing the speaking.”
