### 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.

A stunning new photography book, “TIME Planet Earth: An Illustrated History”, captures the natural miracles of the world we live in

### Clouds

![Ed Darack / Science Faction / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blt190838151ff12193/698a5cf7457a5274cad6af89/planet_earth_01.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

Water is a shape shifter: familiar in its liquid and frozen forms, it is invisible in its third form, as a vapor, until it coalesces into clouds overhead or shrouds us in ghostly fog. One of nature's everyday wonders, clouds hide in plain sight until they are touched with the sun's glory at sunrise and sunset or pile up to form a lightning-generating, anvil-headed cumulonimbus thundercloud. Ed Darack / Science Faction / Getty

### Meltwater

![Uriel Sinai / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/bltebee2cf81ffe9b63/698a5cf89d83e81d7eb9ab8b/planet_earth_10.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

Glaciers around the world are melting at a precipitous rate. In some cases, the meltwater can form into flowing streams, like this one in Greenland. The water can also penetrate cracks that run deep within the ice, eventually making its way to the ground, where it acts as a lubricant, causing glaciers to slide more quickly toward the sea. Uriel Sinai / Getty

### The Sun

![NASA](https://static.time.com/v3/assets/bltea6093859af6183b/bltafb9b22818cf19c3/698a5ceccabb1d2114e54bd7/planet_earth_02.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

A NASA camera captures the eruption of a giant solar prominence — a burst of the ionized gases, or plasma, that make up the surface of the sun. Some solar flares are hundreds of thousands of miles long, so vast they could straddle the distance between the Earth and the moon. NASA

### Ice

![Martin Ruegner / Image Bank / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blta8c6efbe9c51dde7/698a5cecdb29875b1b26c4a8/planet_earth_03.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

The residue of an ice storm glazes a beech tree, pushing its branches to a near-breaking point. storms are formed when two layers of cold air (one near the earth's surface, another far above) sandwich between them a tier of warm air. Precipitation from the top layer starts out as snow, but when it falls into the middle, warmer belt, it melts into rain. Then, on its way through the lowest belt, it undergoes a little-understood process known as "supercooling" which causes it to chill well below the freezing point of water, yet still remain liquid. When this unnaturally cold water hits the ground, it instantaneously freezes into a translucent glaze that takes on, in intricate detail, the shape of whatever it surrounds. Martin Ruegner / Image Bank / Getty

### Snowflake

![Kenneth Libbrecht / Visuals Unlimited / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blt68624f75fa289cc3/698a5ced86f68e51426f5ca7/planet_earth_04.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

We've all heard that no two snowflakes are identical. The notion may be more poetic than scientific, but it effectively makes its point: that nature is both staggering in its diversity and remarkable in its precision. The geometry of snowflakes is a reminder that nature's actions, however unpredictable at times, are governed by basic laws of physics and mathematics. Kenneth Libbrecht / Visuals Unlimited / Getty

### Cavern

![Tyler Stableford / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blt218c48fed95fcd95/698a5ceedb2987403126c4b5/planet_earth_05.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

Ice caverns like this one in Iceland may resemble caverns of rock, but they are, fact, quite different. While stone caves may take eons to form, cathedral-sized galleries of ice can be carved within glaciers by meltwater in years or even months. And unlike rooms gouged from solid rock, glacier caves can disappear even faster than they were formed. Stone caverns rarely collapse, but ice caves are always vulnerable to cave-in. Veteran glacier spelunkers, or glaciospeleologists, as they call themselves, tell of striking walls inside an ice cave with a hammer to anchor a rope, only to watch a crack hundreds of feet long appear with lightning-fast speed. Tyler Stableford / Getty

### Formation

![John Lawrence / Image Bank / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blta9087d116f9d64dd/698a5cee16d8845097c3f490/planet_earth_06.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

Ireland's Giant's Causeway is constructed of 40,000 basalt columns. Most of them are hexagons, but there are also columns with four, five, seven and eight sides, clustering in a honeycomb pattern and thrusting as high as 36 ft. into the air.They were formed following volcanic eruptions around 50-60 million years ago, when molten basaltic lava cooled, then fractured along strict mathematical lines as it hardened, forming straight edges as sharp as those seen in quartz formations. Giant's Causeway was recognized as a World Heritage Site by UNESCO in 1986. John Lawrence / Image Bank / Getty

### Geyser

![Scott Sady / America 24-7 / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blt6551dbc6ff32dd09/698a5cef9862f5828e89656d/planet_earth_07.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

Like volcanoes and earthquakes, geysers and hot springs open windows onto the potent forces hidden beneath the skin of the planet. Fly , above, lies in the geyser-rich region around Black Rock Desert in Nevada, the dry bed of an ancient lake. This formation is in part man-made: farmers drilling for water in 1916 tapped into a hydrothermal aquifer that flooded the area. In the 1960s the geyser itself began spouting; it does so in a constant stream, unlike geysers such as Old Faithful in Yellowstone National Park, whose vented water flows back underground, only to be reheated and released on a steady timetable. The cone-shaped spouts above have formed over the years as emitted minerals solidify, and they are still growing. Scott Sady / America 24-7 / Getty

### Limestone

![Wilfried Krecichwost / Image Bank / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/blt1fbc28e13cce4000/698a5cf086f68eb8186f5cac/planet_earth_08.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

A limestone pinnacle at New Zealand’s Cathedral Cove rises from the ocean. Because it is a hard sedimentary rock, limestone is often the last type of stone to erode in landscapes primarily composed of sedimentary rock. its sturdy nature have made it a preferred construction material for centuries. It is the backbone of both the Pyramids and the Parthenon. Wilfried Krecichwost / Image Bank / Getty

### Sea Life

![Paul Nicklen / National Geographic / Getty](https://static.time.com/v3/assets/bltea6093859af6183b/bltcd40b702d71ed5b5/698a5cf1011682985f986714/planet_earth_09.jpg?branch=production&width=1200&quality=75&auto=webp&crop=16:9)

A pod of narwhals makes its way through an ice passage in the Arctic. The unicorns of the sea, Monodon monoceros are members of the order Cetacea, along with whales, dolphins and porpoises. Unlike baleen whales, which filter small prey from the water, narwhals are toothed whales that feed on small fish. Male narwhals grow a distinctive single tusk, though some female narwhals have one.
