### 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.

Iran threatened to close the Strait of Hormuz, in what would serve as [another act of retaliation](https://time.com/7296830/iran-qatar-air-base-trump/), after the U.S. launched [strikes on three key Iranian nuclear facilities](https://time.com/7296469/u-s-strikes-iran-nuclear-trump-war/) over the weekend. While there was a brief reprieve in the tension after President Donald Trump announced a cease-fire between Israel and Iran on Monday, the conflict has erupted again, with both sides accusing each other of [breaking the preliminary cease-fire terms](https://time.com/7297098/israel-iran-ceasefire-broken-missile-strikes-tehran/). Now, concerns over the Strait of Hormuz are once again at an all-time high.

Iran controls the Northern side of the Strait of Hormuz, a passage which sees significant global trade pass through daily. If it so wished, Iran could block vessels from journeying through, or disrupt trade by seizing and attacking shipping containers and oil or gas tankers in the area. With [roughly 20 million barrels of oil](https://www.eia.gov/todayinenergy/detail.php?id=65504) passing through the Strait daily, making up about a fifth of global consumption, any interruption could be catastrophic.

Here’s what to know about the Strait of Hormuz, its grave importance, and what stands to happen if the passage is disrupted amid the [ongoing Israel-Iran conflict](https://time.com/7293976/israel-iran-attack-war-hezbollah/), of which the [U.S. is now an active participant](https://time.com/7296512/iran-responds-united-states-strikes-trump-nuclear-sites-warning/). 

## **What is the Strait of Hormuz?**

The Strait is narrow, stretching roughly 31 miles at its widest point. Iran is on its north bank opposite Oman and the United Arab Emirates (UAE).

Most oil exports from Kuwait, Iraq, Saudi Arabia, Qatar, and the UAE pass through, as well as Iran’s own exports. [Around 20% of global liquid natural gas](https://www.reuters.com/business/energy/qatar-met-with-energy-majors-discuss-risks-israel-iran-war-sources-say-2025-06-20/) exports also flow through the passage, mostly originating from Qatar. 

The passage has long been [an area of tension and geopolitical significance](https://time.com/5632388/strait-of-hormuz-iran-tanker/).

In 2019, [two ships were struck](https://www.theguardian.com/world/2019/jun/13/oil-tankers-blasts-reports-gulf-of-oman-us-navy), one flying [a Marshall Islands flag](https://www.vesselfinder.com/vessels/details/9745902) and the other [from Panama](https://www.bbc.co.uk/news/world-middle-east-48627014), whilst passing through. The U.S. blamed Iran for the attacks, which Tehran denied. A month prior, [four other tankers](https://www.bbc.co.uk/news/world-middle-east-48245204)—two from Saudi Arabia, the others from the UAE and Norway—were struck by suspected underwater mines, which the U.S. accused Iran of planting.

Noam Raydan, a senior fellow at the Washington Institute and an expert on energy and maritime risks, says that some countries, such as Iraq, rely on the Strait for nearly all of its energy exports, whereas other exporters have fairly reliable alternatives to fall back on, should disruption occur.

**Read More**:[ _Even Iranians Beaten and Imprisoned by an Unforgiving Regime Condemn Foreign Interference. Here’s Why_](https://time.com/7296872/iranians-beaten-imprisoned-regime-condemn-foreign-interference/)

## **What has Iran said about closing the Strait of Hormuz?**

The Iranian Parliament on Sunday [voted in favour of closing ](https://www.presstv.ir/Detail/2025/06/22/750031/iranian-parliament-moves-close-strait-hormuz-after-us-aggression-lawmaker)the Strait of Hormuz. The decision of whether to carry out that action now lies with Iran's Supreme National Security Council and the Supreme Leader Ayatollah Ali Khamenei.


“Just verbal threats from Iran are causing concerns in the global market. So imagine how the impact will be if they _really_ acted on their threats,” says Raydan.

However, the maritime expert believes that a complete closure of the passage is unlikely as it would cause just as much harm to Iran themselves.

“The Strait of Hormuz is very important to Iranian allies such as China, because [most of Iran's oil](https://www.bbc.co.uk/news/articles/c78n6p09pzno#:~:text=In%202022%2C%20around%2082%25%20of,exports%20to%20the%20global%20market.) goes to China. Closing the Strait would also turn relations between Iran and the GCC \[Gulf Cooperation Council\] countries sour,” Raydan says, adding that Iranian relations with GCC countries such as Saudi Arabia and the UAE are currently stable and also not worth risking.

“Iran can cause disruptions and keep the oil markets jittery by only carrying out individual maritime attacks,” Raydan argues, saying isolated assaults are far more likely than a closing of the entire passage.

She warns, however, that should Iranian energy infrastructure be targeted in further attacks, the Iranian response could be more severe, but "for right now, we should \[instead\] consider the maritime arena… there's [a track history of Iran](https://www.reuters.com/markets/commodities/iran-oil-doomsday-hormuz-may-be-more-fear-than-reality-bousso-2025-06-22/#:~:text=Moreover%2C%20while%20Hormuz%20has%20never,and%20even%20U.S.%20navy%20ships.) using that to retaliate.” 


Iran took part in the so-called Tanker War during the 1980s amid active conflict with Iraq, which saw oil tankers targeted by the Iranian military. The U.S. became involved and protected the tankers, in particular those flying U.S. flags, which it is bound to protect under maritime law.

## **Has Iran threatened to close the Strait of Hormuz before—and did it follow through on its threat?**

Iran previously threatened to block the strait in 2011, when Iran’s then-Vice President Mohammad Reza Rahimi declared that oil would not pass through the waters if Western sanctions against Iran were widened. The sanctions were issued as a result of concerns over [Iran’s nuclear capabilities](https://time.com/7294133/iran-israel-nuclear-program-attack/)—the very topic at the forefront of the current conflict.


In this instance, Iran did not follow through on its threat.

As [TIME noted in 2011](https://nation.time.com/2011/12/28/can-iran-close-the-strait-of-hormuz/): International maritime law guarantees unimpeded transit through straits, and any deliberate military disruption can be considered an act of war.

## **What would be the impact on global trade if Iran closes the Strait of Hormuz?**

Oil exporters and importers would stand to be vastly impacted by a closure. And the economic ripple effect would surely be felt far and wide.

According to Deutsche Bank, the cost of a barrel of oil could surge [to around $120](https://www.nytimes.com/2025/06/16/business/oil-prices-iran-israel.html), should Iran block the passage or cause disruption to its shipping lanes. The cost of a barrel currently stands [at around $75](https://markets.businessinsider.com/commodities/oil-price).

John Konrad, author and founder of maritime news site gCaptain, says that barriers on new tanker constructions and any disruption to production chains could have a “massive” economic and social impact.

“If you have a slowdown in natural gas, you could have a slowdown in fertilizer,” he says, adding that this could lead to “food shortages and unrest” in a worst-case scenario. The “ton mile cost” of shipping oil and natural gas will largely increase if Iran were to block trade through the Strait of Hormuz, Konrad argues, even if importers find alternative sources.


“The main thing about disruptions and shipping is the ton mile. How many miles does it take to move a ton of oil, and what is that cost?” Kondrad notes. “The United States is a lot further away from Europe, and much further away from the massive energy consumption in China and Japan and Korea than the Middle East. So what makes the Middle East \[so powerful\] is not only the abundance of oil, but its central location between Europe and Asia.”

European consumers would also feel the impact of any disruption in Hormuz, specifically North-West Europe, when it comes to the prices of gas, oil, and jet fuel.

“U.S. refineries might intervene and substitute any gap, but still, disruptions would be felt. Prices will be higher,” Raydan says, adding that there would also be logistical issues, similar to those felt when [Houthi strikes disrupted trade in the Red Sea](https://time.com/6553141/red-sea-houthi-attacks-consumer-prices-cost/) following the start of the Israel-Hamas war.

## **How have lawmakers from the U.S., U.K., China, and beyond responded?**

U.S. Secretary of State Marco Rubio warned against action in the Strait of Hormuz from Iran in [an interview with Fox News](https://www.youtube.com/watch?v=APD5gNeIJjY) on Sunday. 

“I would encourage the Chinese government in Beijing to call him \[Khamenei\] about that because they \[China\] heavily depend on the Strait of Hormuz for oil,” Rubio said when asked if he expected Iran to close the Strait and disrupt global oil supplies.

Rubio emphasized the U.S. viewpoint that any measures taken to disrupt supply chains in the Persian Gulf would be “another terrible mistake.”

“It’s economic suicide it they do it and we retain options to deal with that. It would be a massive escalation that would merit a response,” he warned.

[China has also expressed](https://time.com/7296139/china-iran-israel-us-weapons-mediate-war-peace-oil-diplomacy/) deep concern over the escalating conflict, and the potential for disruption in trade.


“The Persian Gulf and nearby waters are \[an\] important route for international trade in goods and energy. Keeping the region safe and stable serves the common interests of the international community,” said Guo Jiakun, the spokesperson for China’s Ministry of Foreign Affairs, [during a press conference on Monday](https://www.mfa.gov.cn/eng/xw/fyrbt/202506/t20250623%5F11655211.html). "China calls on the international community to step up effort to promote de-escalation of the conflict, and prevent the regional turmoil from having a greater impact on global economic growth."

Jiakun went on to emphasize that "China stands ready to step up communication with Iran and other relevant parties to continue playing a constructive role for a de-escalation."

U.K Foreign Minister David Lammy also spoke out on Monday, expressing concerns over the news from the Iranian parliament.

“It would be a mistake to blockade the Strait of Hormuz, I think he \[Khamenei\] gets that and understands that,” a hopeful Lammy told [the BBC](https://www.youtube.com/watch?v=ilThNAQrboI).


In agreement, Kaja Kallas, the European Union representative for foreign affairs and security policy, told reporters on Monday:“The closing of the Strait of Hormuz is something that would be extremely dangerous and not good for anybody.”
