### 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.

Looming 2,799 m (9,183 ft.) above sea level, Gunung Ijen in Indonesia’s eastern Java is a volcanic wonder that attract hundreds of foreign and domestic tourists daily. During daytime, they climb the mountaintop to reach Kawah Ijen, the volcano’s crater lake famous for its mesmerizing turquoise hue. When darkness descends, hikers clamor to witness the glowing blue liquid fire that streams from the crater down the mountainsides. It isn’t lava, but the sulfur for which Kawah Ijen is renowned.

It is also sulfur that brings hundreds of miners to Kawah Ijen every day. They make the perilous journey climbing 9,000 ft. to the summit and then 3,000 ft. down into the crater. The miners descend to the womb of the volcano, defying scorching heat and rarefied air, in search of the precious material that is used to manufacture countless products — from matches, rubber, insecticides and fertilizer to cosmetics, batteries, sugar and film.

Rome-based photographer Luca Catalano Gonzaga traveled to Indonesia in late last year and spent 10 days at Gunung Ijen to capture the miners’ daily toil. Many of the photos were taken after dark, as many men prefer to work when the heat is more tolerable.

Gonzaga titles his project “Devil’s Gold,” a biblical allusion to hell as the fiery lake that burns with brimstone — the ancient name for sulfur. Sulfur mining at Kawah Ijen is certainly a hellish job. Not much has changed since mining officially began here in 1968\. Every day, around 300 men leave the base camp carrying traditional equipment like torches and metal poles to break the sulfur slabs, though with little protective gear. Only a few men are given gas masks, while the rest rely on wet scarves or rags to cover their mouths, in a largely futile attempt to protect themselves from the caustic gas that singes the eyes, throats and lungs, and can even dissolve teeth.

Once the miners collect their sulfur, they haul the fully loaded baskets, weighing between 70 kg (150 lb.) and 90 kg (200 lb.), out from the crater, climbing 60-degree slopes, and then down to the base camp. They get 10,000 rupiah (78¢) for 10 kg (22 lb.) of sulfur. Suwono, 33, works four days a week, from 6 a.m. to 2:30 p.m., to support his wife and son. Carrying 70 kg of sulfur twice a day earns him 140,000 rupiah ($11) — but it also comes with a price: Suwono has a disfigured back. Deformed spines and bent legs are disturbingly common among miners.

Such physically demanding and hazardous work means miners’ average life expectancy barely reaches 50 years. More than 70 people have died in work-related accidents at Kawah Ijen in the past four decades, many due to the toxic fumes that billow suddenly from the rock’s fissures.

Aware of the risks they face daily, the miners don’t want their children to follow in their footsteps. “They want to throw off the shackles of a destiny,” Gonzaga says, “for this reason, they push their kids to go to school and have an education.”


“Devil’s Gold” is part of a wider project called Invisible People, which is funded by Nando Peretti Foundation.
