### 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.

For more than a century, ironworkers descended from the Mohawk Indians of Quebec have helped create New York City’s iconic skyline, guiding ribbons of metal into the steel skeletons that form the backbone of the city. In the tradition of their fathers and grandfathers, a new generation of Mohawk iron workers now descend upon the World Trade Center site, helping shape the most distinct feature of Lower Manhattan—the same iconic structure their fathers and grandfathers helped erect 40 years ago and later dismantled after it was destroyed in 2001.
Driving some 360 miles south to New York from the Kahnawake reserve near Quebec, these men work—just as their fathers did—in the city during the week and spend time with their families on the weekends.
One year ago, around the tenth anniversary of the September 11th attacks, photographer Melissa Cacciola began documenting some of these workers—not an easy task given that the roughly 200 Mohawks (of more than 2,000 iron workers on site) are working at a frantic pace, helping One World Trade Center to rise a floor a week.
Cacciola, a photographer with a background in chemistry and historic preservation, is one of few photographers who work exclusively with tintypes, images recorded by a large-format camera on sheets of tin coated with photosensitive chemicals. Having previously photographed members of the armed-forces for her [_War and Peace_](http://melissacacciola.com/war-and-peace) series, Cacciola looked to document those continuing to help the city move past the shadow of tragedy.
“It seemed like a real New York thing,” she told TIME. “And it made sense as the next chapter in the post-9/11 landscape. Rebuilding is part of that story.”
Just as towers like the Empire State Building and Rockefeller Center mark the height of America’s skyscraper architecture, tintype photographs are inherently American. Tintype developed in the 1850s as early American photographers looked for alternatives to the expensive and finicky glass-plate processes popular in Europe. Recycled tin was a readily available resource in the new nation—less than 100 years old—and so the tintype grew in popularity, earning its place in American photographic identity. Even Abraham Lincoln’s campaign pins contained an inlaid tintype portrait of the candidate.
“You don’t find tintypes on other continents,” Cacciola said.
Slightly blurry and sepia-toned, Cacciola’s portraits feel timeless, save for the occasional modern stickers on her subjects’ hardhats. Each portrait focuses tightly on the men’s strong facial features.
The 30 tintypes in the series are each made from bulk sheets of tin, although Cacciola has also used recycled biscuit jars in prior tintype projects. Coated first with a black lacquer and then a layer of collodion emulsion to make them light sensitive, the plates are dipped in a silver bath immediately before exposure to form silver iodide—a step that bonds actual particles of silver to the emulsion. Nothing could be more fitting for men working with steel to be photographed on metal.
In the tradition of 19th-century photography, Cacciola’s process is slower than today’s digital systems. But the finished plates are more than simple portraits; rather, they hold their own weight as tangible objects. Just as histories often reflect the blemishes of times past, Cacciola’s tintypes are fragile, containing marks and slight imperfect artifacts that reflect the medium’s limitations. Working by hand rather than machine, each portrait records the artist’s intentions as much as her subject’s.
“These tintypes are so much a part of me,” she says. “Like the fact that you get partial fingerprints or artifacts from the way I’m pouring collodion on the plate—it’s all human. The way silver and light interact in this chemical reaction is a testament to the Mohawk iron workers and this early \[photographic\] process—it’s unparalleled in terms of portraiture.”
[_Melissa Cacciola_](http://www.melissacacciola.com/) _is a New York-based tintype photographer._
Geggs Martin 15 years, Connector "One job I'll always remember is working on the transit hub at the World Trade Center. Some of the iron was huge. I'll never forget that feeling of seeing those pieces of iron, some 13 ft. high and 60 ft. long, flying at you. Awesome." Melissa Cacciola
Jim Morris 42 years, Foreman “I grew up playing on steel, on a bridge built in the late 1800's—The Company Pacific Railroad Bridge. My father was an ironworker. I was in college to become an accountant. I took a semester off to do some ironwork. Once I got into it, I really enjoyed it and never went back to school. My father put up a tower crane on the original WTC site. Last year, I erected a crane in Tower 2\. It was a strange feeling going down into the footprint of the building, knowing that so many people had died there.” Melissa Cacciola
Peter Jacobs 32 years, Connector/Signal-man “My whole family, from my dad’s side right on down, is in the business. That’s how I got into it. Seeing my father and grandfather, I always wanted to be an ironworker since I was 9 or 10 years old. It’s been an honor to build the tallest building in the United States. I can tell my grand-kids that I helped build this. The WTC, Tower 1, would be the highlight of my 30-year career as an ironworker. Knowing the height of the building and what it means to the people who lost their loved ones…it is like a victory for us and the people.” Melissa Cacciola
Harrison Printup, Jr. 42 years, Journeyman “I got into ironworking because it was a family tradition—my father, all of my uncles and my grandfather were all ironworkers. The freedom, the pride, seeing something each day that wasn’t there before, traveling….these are the things I enjoy most about ironworking.” Melissa Cacciola
Preston Horn 29 Years, Journeyman/Bolter-up “My father, grandfather, great-grandfather and uncle were all iron-workers in New York. My father worked on the original WTC; my dad taught me everything I know.” Melissa Cacciola
Martin Montour 1.5 years, Apprentice “What do I like most about ironworking? Working hard, having pride in my work, continuing tradition, living in NYC, building the best city in the world and learning and experiencing life!” Melissa Cacciola
Tommy Herne 27 years, Journeyman "I got into ironworking because everyone back home was doing it. My brother had started doing it and I needed a job. I really liked working on the WTC site and seeing it rebuilt—seeing the progression of the construction and the building as it went up and looking down (from Tower 4) and seeing the memorial. We all learn something on every job—it may not be something new, but it may be that you get reminded of something. It's an ongoing thing." Melissa Cacciola
Joseph McComber 36 years, Journeyman "My father was an ironworker and his father. It was a family thing. It's a good living—that's for sure. I worked with my father at the Meadowlands and Tower 56--he taught me everything I know. What do I like most about ironworking? Challenging your brain with work situations and meeting strange and unusual people." Melissa Cacciola
Adenharis’hon Jacobs-Lahache 10 years, Connector/Foreman “I had been welding in a fabrication shop back home in Canada when I heard of the ironworker recruit-men and decided to give it a shot. My grandfather and a few of my uncles had been ironworkers, but had long since hung up their belts. The Mohawk men that come out here to work so far from our homes and family, come out here to do hard, honest work that we are good at. We may have fun doing our work, but at the end of the day I miss being with my family.” Melissa Cacciola
William Jacobs 32 Years, Journeyman It is an honor to work at the WTC. It's a proud moment that my son got to work on this building on his first job. Working with my son here would have been something that I would have loved to have done with my Dad, but he passed when I was 16 years old. If someone were to see my portrait, I'd want them to know you're looking at someone who did their best to carry on the tradition of the Mohawks and that you could see that I worked hard." Melissa Cacciola
John McGowan 30 Years, Bolter-up “As a kid, I used to play on the bridge back home in Kahnawake, walking on the iron archway and spans under and over the river. At the time I became of age, I wanted to give ironworking a try. All of my friends and relatives were in the business. They all talked about the jobs they’ve worked on and how proud they were of doing this job. My father and grandfather were ironworkers and I wanted to keep the tradition and honor alive. It’s a great honor to work on the WTC site because my father and grandfather both worked on the original site. I was there for the search and rescue, as well as the clean-up on 9/11, so I wanted to be part of the rebuilding.” Melissa Cacciola
Turhan Clause, Jr. 27 Years, Journeyman “My father, grandfather and uncles were ironworkers. All of my brothers are also ironworkers. My father once told me, 'Son, I don't have a lot of money or a house to leave you when I pass on. The only thing I can do is show you an honest way to make a living.' So he took me to my first job as an ironworker. It was exciting and a little scary at the same time. And I still haven’t found anything better!” Melissa Cacciola
