### 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 Zika virus, which has been linked to an increase in Brazil of a birth defect called microcephaly, was first identified in a Ugandan forest in 1947\. Scientists now suspect that it is endemic across most of the African continent. Which raises the question: why aren’t we seeing a similar surge of microcephalic babies in Africa?

**Read More:** [**Here Are the Other Zika Problems Experts Are Worried About**](http://time.com/4209612/zika-guillain-barre-syndrome-cdc/)

The answer to that question could provide vital clues about a virus that largely remains a mystery, nearly 70 years after its discovery. Does the mosquito-borne disease actually [cause](http://www.cbc.ca/news/health/microcephaly-brazil-zika-reality-1.3442580) the birth defects, and [if so](http://www.nejm.org/doi/full/10.1056/NEJMoa1600651), how? What other effects might it have? Did it evolve into a more virulent form as it made the long journey from Africa to South America, and if so, how much more dangerous is it now?

The fact that there is no documented evidence of Zika-linked microcephaly in Africa has caused many scientists to think harder about the connection between the virus and the birth defect. “I have never seen anything in any literature from Africa describing these kinds of severe manifestations linked to Zika,” says [Scott C. Weaver](http://www.utmb.edu/pathology/faculty/weaver/weaver%5Fbio.htm), the scientific director of the Galveston National Laboratory in Texas, and an expert on human infections and immunity. “So what we really don’t know, and need to find out, is whether this virus has always had this capacity to produce these outcomes or whether the virus changed, or whether there is something different about the people that it is infecting in the Americas.”

On the surface, comparing the impact of the sudden outbreak in Brazil to the virus’ decades-long existence in Africa is “sort of like comparing apples to oranges,” says [Dr. Michael Edelstein](https://www.chathamhouse.org/expert/michael-edelstein), an epidemiologist with [Chatham House’s Centre on Global Health Security](https://www.chathamhouse.org/about/structure/global-health-security) in London. Medical reporting is much stronger in middle-income countries like Brazil than in desperately poor African countries that have limited health programs and major health challenges, so it could simply be a question of missing data. “The ability to detect public health events in Brazil in 2016 is much better than it was in Uganda in 1947,” says Edelstein.

It’s notable that the mosquitoes that transmit Zika in Africa prefer to live in sparsely populated forest areas, unlike the _Aedes aegypti_ mosquitoes transmitting the virus in South America, which thrive in densely packed cities. So while Zika is believed to have infected 1.5 million in South America, the biggest, and only, recorded outbreak in Africa was in [Gabon, in 2007](http://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0002681), which infected an estimated 20,000 people. Statistically that’s too low to detect rare complications like microcephaly, says Edelstein.


Viruses or chemical exposure or even alcohol can cause microcephaly, and it occurs around the world. So in Africa’s rural areas, where the number of births is low, even a 300 percent increase in microcephaly cases, which would trigger an alarm in an urban hospital, could pass unnoticed. “It could mean an increase from three to five cases a year,” says Edelstein. “Unless you are looking for it, you are unlikely to find it.”

[Helen Lazear](https://www.med.unc.edu/orfeome/people/faculty/helen-lazear), an assistant professor in the department of microbiology and immunology at the University of North Carolina School of Medicine in Chapel Hill, agrees, but notes, there might be other factors at play. “There could be something very different about the virus strains circulating in Africa and in Brazil,” she says. Scientists are genetically sequencing different Zika strains from Africa, the South Pacific and South America, and they have identified a small number of changes in the genome as the virus traveled the globe. “What we don’t know is if those few changes are just random—viruses do change over time—or if those changes actually impact the virulence of the virus.”


That’s what Weaver’s team at the Galveston National Laboratory plans to work on next. If a genetic sequence is like a recipe, it’s impossible to tell how different recipes work together until you try them. By infecting lab animals with different strains of the virus, scientists will be able to figure out which genetic mutations make a difference in how the virus works, and whether those mutations might cause microcephaly. “If the virus has, over time, become more efficient at replicating in humans \[that\] could also be a reason why microcephaly rates would increase,” says Weaver. “The more efficient the virus is at replicating itself, the greater the amount of virus there is in the blood stream, and the more likely it is to cross the placenta into the fetus,” which could cause developmental problems.


But the most likely explanation for why Zika hasn’t caused as many problems in Africa as it has in Brazil also provides the most hope. Africans have had decades to build up a resistance to a disease that most South Americans are encountering for the first time. “Virtually everyone in South America is immunologically naive,” says Weaver. “Combine that with large, densely packed cities full of _Aedes aegypti_ mosquitoes and you have all the fuel you need for a major epidemic like this one.”

That in turn means a greater likelihood of seeing an increase in rare complications such as microcephaly. But in Africa, there is far less concern, even if there is another outbreak down the line, says Weaver. “If there is regular circulation in Africa of Zika, it may even be that many women, once they reach childbearing age, have already been infected and are immune.” That provides hope, and a template, for future vaccine development.
