### 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.

Iranian forces on Friday [seized the ](https://time.com/5630902/iran-britain-tanker-reciprocal/)[British-flagged oil tanker _Stena Impero_](https://time.com/5630902/iran-britain-tanker-reciprocal/) in the Strait of Hormuz, a geopolitically vital sea route connecting the Persian Gulf and Gulf of Oman. The move has escalated tensions even further amid already strained relations between Tehran and Western powers, which took a nosedive after the U.S. [withdrew from the Iran nuclear deal](https://time.com/5586246/iran-nuclear-deal-anniversary/) last year.

Iranian authorities claimed the _Stena Impero_ was “violating international maritime rules.” But the country’s leaders have also suggested the seizure was retaliation for Britain’s role in detaining an Iranian tanker earlier in July.

Outgoing British Prime Minister Theresa May on Monday called the _Stena Impero_ incident “unacceptable and highly escalatory.” But the U.K. hasn’t yet revealed how it will respond to the tanker’s seizure.

Here’s what to know about the _Stena Impero_ and its connection to rising tensions between Iran and Western powers.

## What is the _Stena Impero_ and who was on board?

The _Stena Impero_, a U.K.-registered oil tanker, was traveling to a port in Saudi Arabia on Friday when Iran’s Revolutionary Guard stopped it in the Strait of Hormuz and took it to the nearby Iranian port of Bandar Abbas.

The vessel’s crew of 23, including Indian, Latvian, Filipino and Russian nationals, are believed to be in “good health,” according to a [statement](https://www.stenabulk.com/) from Stena Bulk, the company that owns the _Stena Impero_. The company said it has made an official request to visit its crew members, but Iran has not yet formally responded.

Audio of the incident [shared Sunday by a risk consultancy group](https://twitter.com/GlobalDryad/status/1152671785407717376) features what is allegedly an English-speaking member of the Revolutionary Guard telling the _Stena Impero_ crew to alter their course. “If you obey, you will be safe,” they said.

## Why is the Strait of Hormuz important?

The Strait of Hormuz, off Iran’s southern coast, is a crucial waterway for international oil flows, with [17.4 million barrels](https://www.reuters.com/article/us-saudi-oil-emirates-tanker-factbox/factbox-strait-of-hormuz-the-worlds-most-important-oil-artery-idUSKCN1TE1PS) passing through each day. That’s around a third of all oil transported by sea, and a fifth of the world’s total oil supply.

Members of the international oil alliance OPEC, including Saudi Arabia, rely heavily on the Strait of Hormuz, which is only 21 miles wide at its narrowest point, to export their oil to the rest of the world.

The seizure of the _Stena Impero_ has highlighted how international tensions have left vessels passing through the chokepoint increasingly vulnerable. Crude oil prices spiked [by more than 2% Friday](https://www.ft.com/content/f1bf813a-aa61-11e9-984c-fac8325aaa04) after the ship was seized.

## Why did Iran stop the _Stena Impero_?

Iran’s relations with the U.S. and other Western countries have been steadily worsening since May 2018, when the Trump Administration unilaterally pulled the U.S. out of the [2015 deal it struck with Iran](https://time.com/5269746/donald-trump-iran-nuclear-deal-macron/) — along with the U.K., France, Germany, Russia and China — in order to curb Tehran’s nuclear program. The U.S. reimposed sanctions on Iran, aimed at crippling its economy. Though European powers have not abandoned the deal or imposed sanctions on Iran, the country’s oil exports have now fallen to their [lowest levels since the 1980s](https://www.bloomberg.com/opinion/articles/2019-07-22/britain-s-iran-debacle-in-strait-of-hormuz-is-like-suez-crisis).


The fallout from the U.S. withdrawal, as well as instability from the war in nearby Yemen, has led to a series of incidents in the Gulf Region since May. The U.S. has blamed Iran for [several attacks on oil tankers](https://www.reuters.com/article/us-saudi-oil-emirates-tanker-factbox/factbox-strait-of-hormuz-the-worlds-most-important-oil-artery-idUSKCN1TE1PS), and both countries claim to have shot down each other’s drones. Iran also said Monday it arrested 17 of its citizens [accused of being spies for the American CIA](https://time.com/5631495/iran-cia-spies/) and had already sentenced some of them to death.

Iran’s ruling Guardian Council has implied that taking the _Stena Impero_ was an act of retaliation for the seizure of an Iranian vessel off the Spanish territory of Gibraltar earlier in July. British marines helped to detain the vessel, which the U.K. said was illegally transporting oil to Syria. “\[The\] rule of reciprocal action is well-known in international law,” a Guardian Council spokesman [was quoted as saying](https://time.com/5630902/iran-britain-tanker-reciprocal/) by Iran’s semi-official Fars news agency.

## How will the U.K. respond to the _Stena Impero_ seizure?


The U.K. — which is awaiting the results of Tuesday’s Conservative Party leadership race to determine its next prime minister — faces a complicated calculation in responding to the seizure of the British-flagged vessel.

British Foreign Secretary Jeremy Hunt — one of the two men in the running to be the next prime minister, alongside favorite [Boris Johnson](https://time.com/5627357/boris-johnson-britain-prime-minister/) — has warned of “serious consequences” if Iran doesn’t release the _Stena Impero_.

But Hunt also [stressed](https://twitter.com/Jeremy%5FHunt/status/1152613412922433536) a desire to “deescalate” the situation. The U.K., which [remains committed to salvaging the Iran nuclear deal,](https://www.gov.uk/government/news/uk-statement-on-irans-commitment-to-the-nuclear-deal) will likely hesitate to reimpose sanctions against Iran lifted as part of the agreement.

The country has also not yet confirmed if it will join the “multinational maritime effort,” dubbed Operation Sentinel, [being planned by U.S. Central Command](https://www.centcom.mil/MEDIA/STATEMENTS/Statements-View/Article/1911282/us-central-command-statement-on-operation-sentinel/utm%5Fsource/hootsuite/) “to increase surveillance of and security in key waterways in the Middle East to ensure freedom of navigation in light of recent events in the Arabian Gulf region.”


Hunt is due to speak to lawmakers about the U.K. response on Monday afternoon local time.
