### 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.

Excerpts from the report of the Commission headed by Associate Justice Roberts which investigated and fixed the blame for the disaster at Pearl Harbor: 

\>In a letter of January 24, 1941, the Secretary of the Navy advised the Secretary of War that the increased gravity of the Japanese situation had prompted a restudy of the problem of the security of the Pacific Fleet while in Pearl Harbor. The writer stated: “If war eventuates with Japan, it is believed easily possible that hostilities would be initiated by a surprise attack upon the Fleet or the Naval base at Pearl Harbor. . . . The dangers envisaged in their order of importance and probability are considered to be: 1) air bombing attack; 2) air torpedo plane attack; 3) sabotage; 4) submarine attack; 5) mining; 6) bombardment by gunfire.” The letter stated the defenses against all but the first two were then satisfactory. 

\>The Secretary of War replied February 7, 1941\. Admiral Kimmel and General Short received copies of these letters. 

\> On October 16, 1941, the Commanding General, Hawaiian Department \[Short\], and the Commander in Chief of the Fleet \[Kimmel\], were advised by the War and Navy Departments of the changes in the Japanese Cabinet, and of the possibility of an attack by Japan on Great Britain and the United States. 

\>November 24, 1941, the Chief of Naval Operations sent a message to Admiral Kimmel in which he stated that in the opinion of the Navy Department, a surprise aggressive movement … by the Japanese . . . was a possibility. 

\>November 27, 1941, the Chief of Staff of the Army informed the Commanding General that hostilities on the part of Japan were momentarily possible. 

\>On the same day (November 27, 1941) the Chief of Naval Operations sent a message to the Commander in Chief of the Pacific Fleet, which stated in substance that the dispatch was to be considered a war warning. 

\>November 28, 1941, the Commanding General received from the Adjutant General of the Army a message stating that the critical situation required every precaution to be taken at once against subversive activities. 

\>The Navy Department sent three messages to the Commander in Chief of the Pacific Fleet; the first of December 3, 1941, stated that it was believed certain Japanese consulates were destroying their codes and burning secret documents; the second of December 4, 1941, instructed the addressee to destroy confidential documents and means of confidential communication; and the third of December 4, 1941, directing that in view of the tense situation the naval commands on the outlying Pacific islands might be authorized to destroy confidential papers. 

\>At about noon E.S.T. (6:30 a.m. Honolulu time) December 7, an additional warning message indicating an almost immediate break in relations between the United States and Japan, was dispatched by the Chief of Staff. . . . The delivery of this urgent message was delayed until after the attack. 

\>The Commanding General \[Short\], the Commander in Chief of the Fleet \[Kimmel\] and their principal staff officers considered the possibility of air raids. Without exception they believed that the chances of such a raid while the Pacific Fleet was based upon Pearl Harbor was practically nil. 

\>On the night of December 6 numerous officers of the Army and Navy attended social functions at various points on the Island of Oahu. The Commanding General and the Commander in Chief of the Pacific Fleet were both guests at dinners away from their posts but returned to their quarters at an early hour. . . . There is no evidence of excessive drinking by any officer of either service. 

\>On the morning of Sunday, December 7, Army posts and Naval vessels and stations were adequately manned by men fit for duty. 

\>In the attack on Oahu a suspicious object was sighted in the prohibited areas off Pearl Harbor at 6:30 a.m. Between 6:33 and 6:45 this object, which was a small submarine, was attacked and sunk by the concerted action of a naval patrol plane and the U.S.S. Ward. A report of this action by the Ward reached the Naval Base watch officer at 7:12 a.m., who notified his Chief of Staff. 

\> December 7, the antitorpedo net at Pearl Harbor was opened at 4:58 a.m. for the entrance of two minesweepers. It was kept open until 8:40 a.m. 

\>The state of readiness prescribed for Army aircraft prior to the attack required them to be ready for flight only after four hours’ notice. ^The aircraft warning system, which was remanned about 8:30 a.m., December 7, 1941, failed during the balance of that day to furnish any reliable information of enemy aircraft returning to their carriers. 

\>During a period of ten days preceding the Japanese attack, the responsible commanders held no … discussion of the meaning of the warnings and orders sent them. The attitude of each demonstrated a lack of appreciation of the responsibilities vested in them and inherent in their positions as Commander in Chief, Pacific Fleet, and Commanding General, Hawaiian Department.
