### 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.

Jun 21, 2016 3:58 PM UTC

**What is happening on Thursday**

Citizens of the United Kingdom of Great Britain and Northern Ireland will vote Thursday on the U.K.’s membership of the European Union. Economists, politicians and people from all over the world forecast that a vote for Britain to leave the E.U., known as ‘Brexit’ [would be catastrophic for Britain](http://www.politico.eu/article/juncker-brexit-a-catastrophe-but-i-wont-campaign-in-uk-leave-remain/) and could create economic and political shockwaves that could crash through Europe and onto the U.S. and the rest of the world. Yet, voters of the U.K. seem almost evenly divided and many are anxiously waiting for the early hours of Friday morning when the result will become clear.

**What is the European Union and how did the U.K. become a member**

After the end of the Second World War in 1945, Britain refused to join the new institutions set up by other European countries to foster greater co-operation and peaceful relations. Britain preferred to focus its trade and investment on its former colonies such as the United States, India, Canada and Australia. By the 1960s, however, Britain decided that it would be better to join what became the European Economic Community—the forerunner of the E.U.—in 1957.

The difficulty was that some European countries, France in particular, did not want Britain to join. In 1961, Britain’s application to join the EEC was rejected. The president of France, General Charles de Gaulle, feared that Britain would act as a Trojan horse for U.S. influence.

After de Gaulle retired, Britain re-applied in 1967 and finally became a member of the EEC, a free-trade zone in 1973.

Since then, the EEC was first renamed the European Community, and later the European Union. Its influence now ranges from trade, human rights, foreign policy to environmental law. The E.U. comprises the European Parliaments, the European Commission—its executive, the European Court of Justice and the European Central Bank.

**Why do some Britons want to leave**

Sovereignty: Many believe that the scope of the E.U.’s powers is so great that it impinges on the sovereignty of the U.K.

Regulation: Others are particularly annoyed by regulations set in Brussels, where the E.U. is headquartered, which they believe prevent businesses from operating efficiently.

Migration: But the biggest issue is migration. One of the key tenets of the E.U. is the free movement of people. This means that Britons can work and live in any part of the E.U. and E.U. citizens can live and work in the U.K. [Around 3 million citizens of other E.U. states live in the U.K. while 1.2 million Britons live elsewhere in the E.U.](https://fullfact.org/immigration/eu-migration-and-uk/) Some Britons blame migrants for unemployment, low wages, and deterioration of the education and health systems. [Some have even blamed migrants for traffic jams](http://www.theguardian.com/politics/2014/dec/07/nigel-farage-blames-immigration-m4-traffic-ukip-reception).


**Why do Britons want to stay**

Peace: Europe was devastated by two wars in the 20th century and the belligerents are now allies within the E.U.

Free trade: The E.U. is the biggest trading bloc in the world and the U.K. has tariff-free access to it. This would be jeopardised by leaving the E.U.

Investment: International investors have chosen the U.K. as their base because it is part of the E.U. Departure would lead many companies to re-consider their location.

Unity: The U.K. cannot avoid having a relationship with Europe, and the E.U. is the forum that has developed as a home for these multilateral communications. Leaving the E.U. and starting to create new mechanisms for bilateral and multilateral communication would create a lot of work with no guarantee of success.


**What would change if the U.K. left the E.U.?**

No states have ever left the E.U. before, so this is uncharted territory. If the U.K. votes to withdraw, its leadership would have two years to negotiate the terms of departure and organise new trading arrangements with hundreds of countries.

A Leave vote could also lead to the fall of the current government and a general election. This uncertainty could have a dangerous economic impact. Many economists believe that the U.K. could go into recession which could unsettle economies all over the world.

In the longer term, by removing itself from the E.U. market, the U.K. would lose the free trade privileges it enjoyed. Conversely, the E.U. would lose the second-largest contributor to its operating budget, and [nearly 15 percent](http://time.com/4207785/these-5-facts-explain-the-debate-over-brexit/) of its GDP.

Other issues would be procedural. The nearly 3 million people from other E.U. states who live in the U.K. and the 1.2 million British citizens living elsewhere in the E.U. [would have to sort out](http://time.com/4296017/brexit-campaign-video-explainer/) their new immigration status. British businesses operating in the E.U. would also have to reassess their legal and financial status.


**Who supports Leave?** 

The Leave campaign has support mostly from the right of the political spectrum. The United Kingdom Independence Party, led by Nigel Farage, has pushed for a referendum since it was created in 1993\. The former Mayor of London Mayor Boris Johnson and five cabinet ministers also lead the Leave campaign.

Abroad, [Russian President Vladimir Putin](https://www.theguardian.com/commentisfree/2016/jan/05/putin-rubbing-hands-brexit-david-cameron-eu) and [presumptive Republican presidential nominee Donald Trump](http://www.nytimes.com/2016/06/20/us/politics/donald-trump-britain-european-union.html?%5Fr=0) have indicated they think the U.K. should leave the E.U.

**Who supports Remain?** 

David Cameron, the Prime Minister, has been joined by the leaders of nearly all the U.K.’s political parties in pushing for a Remain vote. Almost all foreign leaders who have weighed in — including President Barack Obama, Japan’s Prime Minister [Shinzo Abe](http://www.theguardian.com/politics/2016/may/05/japan-prime-minister-britain-eu-shinzo-abe), and E.U. leaders — want the U.K. to stay. A number of celebrities and artists have also [voiced their collective support](http://time.com/4342844/brexit-remain-campaign-letter/), and J.K. Rowling herself recently warned against [believing in illusory “monsters”](http://time.com/4374624/as-an-expert-on-creating-monsters-j-k-rowling-made-this-intervention-in-the-brexit-debate/) by voting to leave.


**What’s current polling**

Polls this weekend were too close to indicate the vote would definitely go one way or the other, but did give a slight edge to the Leave faction. [One phone survey](http://www.wsj.com/articles/sterling-soars-after-brexit-poll-shows-preference-to-stay-in-eu-1466407254) gave Leave a 45% lead over Remain, with 42%, and an online poll had results of [44% to 43%](http://www.wsj.com/articles/sterling-soars-after-brexit-poll-shows-preference-to-stay-in-eu-1466407254). An [opinion poll](http://www.independent.co.uk/news/uk/politics/eu-referendum-poll-44-would-be-delighted-if-britain-voted-to-leave-only-28-would-feel-the-same-if-we-a7089036.html) by _The Independent_ showed Leave supporters were far more passionate than Stay supporters, but its hard to drum up fervor for maintaining the status quo.

**When will we know the result?**

The voting stations will close at 10 p.m. local time, or 5 p.m. EST. There will be some exit polls, but the BBC said it will not conduct one because the margin for error would be too great in this referendum. Results will be counted and released by area [beginning after midnight](http://www.bloomberg.com/news/articles/2016-05-27/first-brexit-vote-counts-set-for-completion-just-after-midnight), but since the total number of votes will determine the outcome, officials may not be able to call the election with certainty until the very end.

Those final tallies will come in throughout the night, finishing up by 7 a.m. local time (_Bloomberg_ breaks down the schedule of results nicely [here](http://www.bloomberg.com/news/articles/2016-06-20/eu-referendum-how-britain-s-brexit-vote-count-will-unfold)). At that time, 2 a.m. EST, the Chief Counting Officer should be able to announce the winner.


**How will this affect the U.S.?** 

Britain is one of America’s major partners in trade, so this monumental change would throw uncertainty into the future of that relationship — especially if the U.K. [enters a recession](http://time.com/4344537/uk-brexit-diy-recession/) as a result. The [International Monetary Fund warns](http://www.imf.org/external/pubs/ft/scr/2016/cr16169.pdf) that a [Brexit](http://time.com/money/4369522/what-brexit-britain-european-union-vote-means-for-economy/) could lower the output of many economies, including the U.S., by up to half a percentage point. The Euro or pound floundering next to a strong dollar would be a blow to American exporters.

Beyond economic ties, the U.S. government is [most concerned](http://www.theguardian.com/politics/2016/jun/20/european-union-referendum-brexit-us-world) about the political instability a Brexit could portend for Europe on the whole. If other states follow suit and leave the largest trading bloc in the world, the entire continent would be weakened — falling into the shadow of a looming Russia. The future of NATO itself could [even be at risk](http://www.telegraph.co.uk/news/newstopics/eureferendum/12194226/Brexit-could-threaten-the-Nato-alliance-says-top-US-general.html).
