### 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.

On May 19, President Donald Trump appeared to set a red line in a tweet: “If Iran wants to fight, that will be the official end of Iran. Never threaten the United States again!”

Nearly a month later, Iran has put Trump’s red line to the test with [apparent attacks on two foreign tankers](https://time.com/5606719/pompeo-iran-persian-gulf-oil-tank-attacks/) transiting through the Gulf of Oman that drove up oil prices and escalated tensions.

The U.S. military [released grainy black-and-white video footage](https://www.centcom.mil/MEDIA/VIDEO-AND-IMAGERY/VIDEOS/videoid/689676/) late Thursday of what officials said were Iranian forces on a patrol boat removing an unexploded mine from a ship — allegedly attacked just hours earlier — in an effort to destroy incriminating evidence.

It was an extraordinarily rare move for the military to quickly declassify such imagery for public consumption, but the footage provided compelling documentation to support the Administration’s claims about Iran’s role in sabotage.

Still, the events Thursday pose a dilemma for Trump. Not responding to the latest attacks, if they were perpetrated by Iran, could encourage even more in coming days. Ruling out even limited military action, such as sinking several small fast-boats belonging to Iranian forces, which often harass U.S. Navy ships in the region, could encourage Tehran to launch even more brazen attacks.

But a large military response would spike shipping insurance rates and oil prices, cost lives and further destabilize the region, officials said. The Gulf of Oman, where the attacks took place, is near the Strait of Hormuz at the mouth of the Persian Gulf, through which much of the world’s oil passes.

Iran denied its involvement in the attacks, but Secretary of State Mike Pompeo insisted that intelligence reviewed by U.S. officials had indicated Iran’s culpability. He provided no evidence to support the assertion at the time, but laid out the Administration’s case. “This assessment is based on intelligence, weapons used, level of expertise needed, recent similar Iranian attacks, and the fact that no proxy group operating in the area has the resources and proficiency to act with such a high degree of sophistication,” he told reporters at the State Department.

It was the latest of several recent attacks in the Middle East that [Pompeo attributed to Iranian government](https://www.state.gov/secretary-of-state-michael-r-pompeo-remarks-to-the-press/). The incidents, he said, included an earlier assault on four tankers in the Gulf of Oman near the Strait of Hormuz, armed drone attacks against Saudi oil facilities, a deadly bombing in Afghanistan and a rocket attack on the Green Zone in the Iraqi capital, Baghdad, where the U.S. embassy is located.


![M/T Kokuka Courageous Damage](https://static.time.com/v3/assets/bltea6093859af6183b/blt810054b3112abb06/69894b357cdbac7502d5fa81/oil-tanker-attack-mine.jpeg?branch=production&width=1920&quality=75&auto=webp)

The U.S. military released this photo late Thursday, June 13, 2019 showing the oil tanker M/T Kokuka Courageous in the Gulf of Oman with damage and what is allegedly a limpet mine. U.S. Central Command

![M/T Kokuka Courageous Damage](https://static.time.com/v3/assets/bltea6093859af6183b/blt50d4faa883c86a63/69894b35b21a9ca96b500be1/oil-tanker-attack-damage.jpeg?branch=production&width=2400&quality=75&auto=webp)

The images show what the U.S. military believes is an unexploded magnetic mine attached to the hull of the tanker M/T Kokuka Courageous following the attack on Thursday, June 13, 2019 in the Gulf of Oman. U.S. Central Command

“Taken as a whole, these unprovoked attacks present a clear threat to international peace and security, a blatant assault on the freedom of navigation, and an unacceptable campaign of escalating tension by Iran,” Pompeo said.

Seven hours later, the U.S. military’s Central Command, which oversees all forces in the Middle East, released footage and a [detailed timeline](https://www.centcom.mil/MEDIA/STATEMENTS/Statements-View/Article/1875666/us-central-command-statement-on-june-13-limpet-mine-attack-in-the-gulf-of-oman/utm%5Fsource/hootsuite/) that revealed what U.S. reconnaissance aircraft observed while responding to the Japanese-owned _Kokuka Courageous_. The crew of 21 was forced to abandon their damaged ship and clamber aboard the _USS_ _Bainbridge_. American sailors observed an unexploded magnetic mine, called a limpet mine, attached to _Kokuka Courageous._


Meanwhile, the U.S. military says, a patrol boat belonging to the Islamic Revolutionary Guard Corps, an arm of the Iranian military, sidled up to the hobbled ship. Footage shows grainy figures on a crowded deck of a small boat floating next to a massive ship. An individual on the boat reaches up and dislodges an object from the ship’s hull.

“At 4:10 p.m. local time an IRGC Gashti Class patrol boat approached the M/T _Kokuka Courageous_ and was observed and recorded removing the unexploded limpet mine from the M/T _Kokuka Courageous_,” said Capt. Bill Urban, Central Command’s spokesman.

The video footage [matches a color photograph,](https://www.centcom.mil/Portals/6/Documents/Statements/MVKOKUKA%20COURAGEOUS.pdf) also released by the military, which apparently shows the unexploded mine before it was removed.

The military condemned Iran’s actions, but indicated the best approach is to find a way out of the growing stand-off. “The United States has no interest in engaging in a new conflict in the Middle East,” Urban said. “However, we will defend our interests.”


The Administration appears divided over how to proceed. There is no dispute that Iran is a bad actor intent on expanding its influence in the Middle East, either directly as its military forces and Iranian-backed political groups have done in Iraq, or by funding and equipping proxies such as Hezbollah in Lebanon and Hamas in Palestine. The dispute is how to respond.

![Sailors aboard the Arleigh Burke-class guided-missile destroyer USS Bainbridge render aid to the crew of the M/V Kokuka Courageous on June 13, 2019.](https://static.time.com/v3/assets/bltea6093859af6183b/blt11235eee2aeb1197/69894b2f22fb856a4ee28644/uss-bainbridge-3.jpeg?branch=production&width=3840&quality=75&auto=webp)

Some intelligence, diplomatic and military officials warn that a U.S. attack on Iran in response to an Iranian attack that neither sank the ships nor injured any crew members could spin out of control.

While Iran is no match for the U.S. militarily, two officials said after the video was posted, if it decides to respond, Iran is most likely to mount an asymmetrical response, perhaps launching cyberattacks or strikes by terrorist groups Tehran supports.


It could take time to prove that Iran was responsible for such attacks, and even if there was conclusive proof, U.S. counterattacks would risk endangering the U.S. and other economies, one of the officials said, speaking on the condition of anonymity without authorization to discuss the issue publicly.

Tensions between the U.S. and Iran have steadily increased since Trump walked away from the landmark multilateral nuclear deal a year ago. The Administration’s [mounting pressure](https://www.whitehouse.gov/briefings-statements/president-donald-j-trump-cutting-off-funds-iranian-regime-uses-support-destructive-activities-around-world/) on Iran began with a war of words but has escalated toward more serious confrontations.

While Pompeo and National Security Adviser John Bolton have argued for a more aggressive response, Trump has been reluctant to use military force and some officials in the intelligence community, the military and the State Department have warned that a military response could easily spin out of control.

“It is quite stunning that Pompeo gave no time and space for conducting a proper investigation before blaming Iran,” said Ali Vaez, the Iran project director at the International Crisis Group. “If Iran was behind these attacks, it clearly shows that Trump’s maximum pressure strategy has rendered Tehran more, not less, aggressive. If Iran is not the culprit, it is clear that some other actor could be trying to engineer a Gulf of Tonkin-type of incident to push the U.S. into a conflict with Iran.”


Either way, the Administration’s aggressive maneuvers and Iran’s responses have created an environment ripe for inadvertent conflict.

Last month, Trump authorized deploying additional troops and firepower to the Middle East to deter what his Administration says is “malign behavior” by Iran that is intended to damage the United States and its allies. A squadron of 12 jet fighters, several spy planes, Patriot missile batteries, a B-52 bomber task force, the _USS Abraham Lincoln_ aircraft carrier strike group and other military assets have [already been dispatched](https://time.com/5586246/iran-nuclear-deal-anniversary/) to the region.

In the latest incident, the U.S. Navy confirmed it received two separate distress calls from the two attacked ships, Norwegian-owned _MT Front Altair_ and the _Kokuka Courageous_, beginning at 6:12 a.m. local time. Images taken at one of the incidents show flames blanketing the ship’s hull while clouds of black smoke billow into the clear sky.


It’s not yet clear how the IRGC could be allowed to get anywhere near the _Kokuka Courageous,_ let alone make away with the only smoking gun that could’ve possibly linked Iran directly to the attacks. The innards of the unexploded limpet mine would’ve undoubtedly provided telltale clues that could help identify the perpetrator.

However, circumstantial evidence against Iran is mounting. Last month’s oil tanker attacks were also carried out with a magnetic mine. Adm. Michael Gilday, the U.S. military’s Joint Staff director, [told reporters at the Pentagon](https://dod.defense.gov/News/Transcripts/Transcript-View/Article/1857948/department-of-defense-briefing-on-iran/source/GovDelivery/) last month that the IRGC was directly responsible for the sabotage of four tankers in the Gulf of Oman. When pressed about the evidence, Gilday said the intelligence was too sensitive to disclose.

One U.S. official said the assessment that Iran is responsible rests partly on the idea that “only Iran has the resources to do this.” While that makes sense, this official said, limpet mines are relatively simple and cheap, and could be triggered remotely or by timer like a roadside bomb, without advanced triggering mechanisms.


While it’s far more likely that Iran did this, this official said, it would be better have positive intelligence rather than an absence of other likely suspects before responding with military action, given the danger of escalation.

Another issue, said one official after Pompeo’s remarks, is distinguishing between the Revolutionary Guard and its Quds Force on the one hand, and Iran’s civilian government on the other. “The Revolutionary Guard is an entity unto itself, so it’s conceivable that the IRGC could have launched these attacks without orders from \[Iranian President Hassan\] Rouhani,” the official said.

In April, the Trump Administration designated the IRGC as a terrorist organization, which restricts members’ banking transactions and ability to travel. It marked the first time the U.S. designated an arm of a nation’s government as a terrorist group. “After being designated a terrorist organization and sanctioned, the Guard certainly had a motive, given the effect the sanctions will have on its economic interests,” the official said. “It’s not like Iran has civilian control of the military, so what’s the right response?”


Since [abandoning the 2015 nuclear deal](https://time.com/5586246/iran-nuclear-deal-anniversary/), the Trump Administration has turned the global financial system into a weapon against Tehran. The policy has triggered an exodus of corporations and financial institutions that would rather abandon their investments in Iran than risk U.S. Treasury Department sanctions.

Iran’s economy-sustaining oil exports have plunged to historic lows from their peak of 2.5 million barrels per day peak in April 2018\. As a result of U.S. sanctions, more than 2 million barrels per day have been taken off the market, which has crippled the Iranian economy.

“No economic sanctions entitle the Islamic Republic to attack innocent civilians, disrupt global oil markets, and engage in nuclear blackmail,” Pompeo said. “The international community condemns Iran’s assault on the freedom of navigation and the targeting of innocent civilians.”
