### 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.

The main barrier to the transplantation of organs from one human being to another is the immune mechanism by which the body defends itself against invasion by foreign substances. The surgical techniques have been perfected for years, and in the case of kidneys at least, the supply of organs has been sufficient for a total of 1,200 transplants. But some 500 of these have failed, in nearly every case because the immune reaction led to rejection of the transplant. Now new ways are being explored to bypass the barrier; last week specialists in surgery and immunology from all over the U.S. met at Duke University to hear about them. 

Cadavers Are Best. The ideal way to get around the rejection reaction is to find an organ donor with the same immunity pattern as the recipient. This happens with any certainty only in the case of identical twins. For patients not so fortunate as to have an identical twin, the conferees agreed, the best source for a donated kidney is a brother or sister, with the mother next. The one-year survival rate for kidneys from close relatives, reported Dr. Joseph E. Murray of Boston’s Peter Bent Brigham Hospital, is now 70%. For the patients themselves, it is 80%. The difference is due to the fact that some patients survive the failure of an initial transplant with the help of the artificial kidney or a second transplant. 

For kidneys removed from cadavers, the corresponding survival figures are 55% and 65%. Astonishingly, the chances of a successful transplant from an unrelated living donor are less than half as good as those for kidneys from unrelated cadavers. Just why, no one knows; perhaps a dying man’s kidney loses some of its power to trigger the rejection mechanism. 

In treating patients with transplants, doctors have been teetering on a precarious seesaw. They must use drugs enough to suppress the immune mechanism and spare the kidney, but not in such strong dosages as to let the patient die from any passing infection. The drugs used, mainly azathioprine (Imuran) and prednisone, are so highly potent that by themselves they can seriously weaken or help to kill a patient. A major factor in boosting the cure rate in the past two years, said Dr. Murray, has been a steady reduction in the dosage of azathioprine. The researchers gathered at Duke were seeking new and gentler ways of avoiding the rejection reaction by manipulating the immune mechanism itself. Among the most promising approaches currently being investigated: 

· LYMPH DRAINAGE. Many of the powerful antibodies against foreign protein are carried by lymphocytes, white blood cells circulating principally in the lymphatic system. Dr. Murray reported on a method in which a plastic tube is inserted in the thoracic lymph duct just above the collarbone. The lymph drains out by gravity into a plastic bag. With good drainage, up to 32 billion cells are removed daily, for as long as four months. They are separated from the lymph fluid by centrifuge, and the fluid is reinfused into the patient through an arm vein. With a well-drained lymph system, said Dr. Murray, rejection crises are only half as common as formerly. 

· ANTILYMPHOCYTE TREATMENT. One way to depress white-cell and antibody activity is to introduce antibody against the lymphocytes themselves. So thymus glands, spleens and lymph nodes are removed from human cadavers, and the extract is injected into horses. The horses’ rejection mechanism goes to work and makes particles active against the human lymphocytes. The horses are later bled, antilymphocyte serum is extracted, and may be further refined to a globulin fraction. At the University of Colorado, a team headed by Dr. Thomas Starzl has performed 19 successful transplants since last June; given antilymphocyte globulin, the patients have got along well on sharply reduced doses of azathioprine and prednisone. 

· ANTIGEN OVERLOADING. Though there are at least two major types of antibody represented by billions of particles, they can be either confused or exhausted if the invading particles of foreign antigen (antibody-triggering substances) are numerous enough. In the medical equivalent of a massive military diversion, doctors try to overload the immune mechanism temporarily by flooding it with antigen particles. By coincidence, an antigen sufficiently similar to the human type is in some streptococci. So these bacteria, usually rated as harmful, are being mass-produced in a program backed by the National Institute of Allergy and Infectious Diseases. The antigen, chemically removed from its microscopic bacterial source, is being distributed to investigating doctors. 

For wide application, said Dr. Kenneth Sell, organ transplantation will have to depend on organ banks, similar to the tissue bank he now maintains for the U.S. Navy at Bethesda, Md. So far, no one has devised a way to freeze a whole organ and get it to work after thawing it out. But another visionary suggestion is for a “living bank,” in which organs from human cadavers might be implanted in baboons and stored in the animals until needed for transplants.
