### 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.

Life is hard, but I don’t need to tell you that. You’ve probably already walked a mile-and-a-half in heels, lugged a bunch of packages to the post office, manned a grill during the lunch shift, or performed any number of other strenuous, everyday activities otherwise known as “work.” Me? I made breakfast, got the wife and kids off to their weekday destinations, walked the dog, and spun around this desk chair twenty-something times thinking about how to write this opener. It’s a good life — I’ll admit that much — but by the end of the day, I’m still exhausted. And now I have proof.

A few weeks ago, I started wearing the [WHOOP Strap 2.0](http://whoop.com/) fitness band, a high-powered but low-profile wearable that professional baseball, ever the numbers game, recently approved for in-game use. And over in the NBA, where WHOOP is still illegal, players like the Clippers’ DeAndre Jordan are [stuffing the sensor under their wristbands](http://www.espn.com/nba/story/%5F/id/18801090/deandre-jordan-plays-hidden-device) to get an edge. These professional athletes are strapping the WHOOP (rather than a Fitbit or Apple Watch) to their bodies because it provides an enormous amount of data on their performance day and night, in pre-game warmups and during post-game recovery. And if it’s good enough for the pros, it’s definitely fair play for this minor league father of two.

WHOOP’s key advantage over other fitness bands is the amount of data this it collects and pushes into the cloud for processing. With five sensors that collect data 100 times per second, the wearable sucks up 100 megabytes of data per user, per day. By comparison, the Apple Watch’s sensors generally turn on just once per minute. But even with all that information, WHOOP’s strength is in its simplicity. After crunching all the numbers (including next-level stats like heart rate variability and sleep latency), the system gives users three metrics to judge themselves against: strain, recovery, and sleep.

The idea is, whether you’re a shortstop or a short-order cook, users wake up in the morning with a recovery score based on the previous night’s sleep that describes how prepared their body is for strain. Then, over the course of the day, their body accumulates more strain in the form of exercise, stress, and just plain old living. Like every fitness monitoring solution, WHOOP can track activities like running or biking, but even mundane tasks like mowing the lawn get sucked into the system, since you’re always wearing the band, and it’s always on. Then, at the end of the day, the system looks at all the strain the body has accumulated (as well as whether or not the user has rested) and it calculates how much sleep you’ll need in order to perform at your peak tomorrow. 


“It’s a cycle,” says WHOOP founder and CEO Will Ahmed. “How much you’ve recovered dictates how much you can strain, which dictates how much more recovery you need.”

The band itself is surprisingly simple. With a sensor that’s designed to sit on the skin, WHOOP is mostly a fabric band with a buckle designed to hold the wearable tight against the arm. WHOOP’s charger is a clever slip-on battery that lets you top-up the wearable on the go. And its straps come in an array of colors and styles that would barely raise an eyebrow in a boardroom, and only cost $15 — a refreshing price, considering the device itself sells for $500\. But when you consider that WHOOP is a sleep tracker, a fitness monitor, and a cloud-based coaching platform, Ahmed argues that price is a good deal.

But it’s not necessarily the hardware (or the professional athletes who are using it) that’s driving WHOOP’s price. The reality for products like WHOOP is that while the cloud might not be visible to consumers, companies that work within it have very real costs. For instance, WHOOP has to collect data for days to establish a baseline of your body’s unique metrics. So before WHOOP even begins to offer actionable insight to its users, it has to collect around a gigabyte of usage data. When it comes to digital services like downloading movies or uploading photos, most consumers think the Netflixes of the world eat those costs, but they’re at least in part covered by your monthly subscription fee. WHOOP doesn’t charge a monthly fee, instead building all its cloud-related costs into the band’s purchase price.

Instead of using WHOOP to work out — which I imagine it’s great for — I wore it while battling a cold. After being sidelined for a couple of years with injuries, I had hoped to use WHOOP’s sensors to quickly get me back into peak running form. But with two kids in daycare, cold and flu season hit me pretty hard, and I was barely able to survive the work day, let alone lace up my running sneakers.

So, I worked with WHOOP. I slept with WHOOP. I walked the dog with WHOOP, all the while dragging myself like a zombie through my days. The longer the cold dragged on, WHOOP’s app told me that I was getting nowhere near the eight, nine, and sometimes 10 hours of sleep my body needed to recover. I was incredulous that I needed as much sleep as WHOOP’s app recommended, but I couldn’t deny that I was getting worse, not better. Coughing fits, a baby with bronchitis, a potty-training toddler — you name it, they were keeping me up at night and dragging me down in the daytime. At rock bottom, I got four-and-a-half hours of sleep, when WHOOP told me that I needed ten-and-a-half. I had no choice but to follow the band’s recommendations, and rest my aching, sick body.


Eventually, I was able to clear my sleep deficit and recover, just as WHOOP said I would, and it became clear to me that it doesn’t take a pro athlete to benefit from this band. In fact, Ahmed describes users who are doing more interesting things with their WHOOP data than merely surviving. For instance, one high-powered executive used WHOOP to figure out how to hack his body to combat jetlag. 

“He does a 15-minute cycling workout within a few hours of getting on a plane if he is traveling over two time zones,” says Ahmed. “He discovered if he did a really short workout before a flight that involves jetlag, he would have a better recovery the next day.”

Eventually I did rebound from my cold, with WHOOP’s nightly reminder of how much rest I truly needed leading the way. Sure, so I wasn’t using it to stay lively during a 13-game road trip, but those aren’t my problems — and they aren’t most people’s problems, either. After all, life is hard enough without having to bounce back from a day/night double-header — but I don’t need to tell you that.
