### 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.

The traffic signals along Factoria Boulevard in Bellevue, Wash., generally don’t flash the same stretch of green twice in a row, especially at rush hour. At 9:30 a.m., the full red/yellow/green signal cycle might be 140 seconds. By 9:33 a.m, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37 a.m. could push it down to 135\. Just like the traffic itself, the timing of the signals fluctuates.

That’s by design. Bellevue, a fast-growing city of more than 130,000 just east of Seattle, utilizes a system that is gaining popularity around the U.S.: intersection signals that can adjust in real-time to traffic conditions. City officials say that these lights, known as adaptive signals, have led to significant declines in both the hassle and cost of commuting.

“Adaptive signals make sure that inefficiencies never happen,” says Alex Stevanovic, director of the Laboratory for Adaptive Traffic Operations & Management at Florida Atlantic University. “They can make sure that the traffic demand that is there is being addressed.”

As city leaders increasingly turn to data for insight into running their metros more efficiently, adaptive signals have emerged as a 21st century strategy to chip away at a longstanding scourge. According to [the U.S. Census Bureau](http://www.census.gov/newsroom/press-releases/2013/cb13-41.html), almost 11 million Americans commute more than an hour each way to their job while 600,000 U.S. residents have one-way “megacommutes” of at least 90 minutes or 50 miles.

And all that time on the roads costs money. The Centre for Economics and Business Research [estimates](http://time.com/wp-content/uploads/2015/05/inrix%5Fcosts-of-congestion%5Fcebr-report%5Fv5%5Ffinal.pdf) that U.S. commuters lost $124 billion in 2013 due to the cost of fuel, the value of time wasted in traffic, and the increased cost of doing business. CEBR predicts those costs will rise 50% by 2030.

Only 3% of the nation’s traffic signals are currently adaptive, but the number of smart signals in the U.S. has jumped from 4,500 in 2009 to 6,500 in 2014, according to Stevanovic, who tracks the signals’ installation around the U.S.

The largest concentration of adaptive signals is in Los Angeles, a city that has long struggled with congestion. Nearby Orange County, Calif. has the second largest, followed by Utah, where about 80% of the state’s traffic signals are adaptive. But the frontier of adaptive traffic management may be in Bellevue, according to transportation policy experts. The city’s overhaul began in 2010 when it began implementing a system called SCATS (Sydney Coordinative Adaptive Traffic System, which was first developed and used in Sydney, Australia). Currently, 174 of Bellevue’s intersections have been outfitted with the new technology with plans for all 197 intersections to use adaptive signals by the end of the year.


The system uses a series of wires embedded in city streets that tell the signals how much traffic is moving through the intersection. When traffic is heavier, the green lights stay on longer. Less traffic means shorter greens. During peak traffic periods, nearby intersections sync their lights to allow long stretches of green. When there are fewer cars on the road, those intersections revert to their own cycles. Mark Poch, the Bellevue Transportation Department’s traffic engineering manager, says uncoupled intersections work more efficiently when there are fewer cars on the road because they can better respond to specific situations at that cross street.

Along Factoria, one of Bellevue’s main downtown arteries, travel times have decreased by 36% during peak rush hour since adaptive lights were installed, according to city transportation officials. Along NE 8th Street, another heavily trafficked street, travel times are down 43% from 2 p.m. to 6 p.m. Those decreased delays appear to add up to real savings for drivers: Bellevue officials say the $5.5 million system saves drivers $9 million to $12 million annually (they estimate that a driver’s time is worth $15 an hour).


For all of Bellevue’s success, adaptive signals are not a panacea for clogged roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so congested that only a drastic reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive has some benefits for a smaller city with a particular corridor on the verge of breaking down,” he says.

In Bellevue, the switch to adaptive has been a lesson in the value of embracing new approaches. In the past, Poch says, there was often a knee-jerk reaction to dealing with increased traffic: just widen the lanes. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.

“It’s been a slow change,” Poch says. “It’s easy to think the way to get out of it is to widen the road. However, as we move toward being better stewards of our resources and more sensitive to environmental issues, let’s take what we have and operate it better. I think that’s a more prevailing thought now, and I think it makes sense.”
