### 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.

Predicting which drugs will work on cancer patients

Doctors play a guessing game about which drugs to use in combatting cancer. One problem is human individuality—what helps one person may fail to help another. In the search for the proper medicine, doctors must often subject a patient to a sequence of powerful drugs, many of which turn out to be ineffective against the malignant cells. Now a simple technique promises a means of testing the effectiveness of drugs in a specific case of cancer—without having to administer them to the patient.

A team of researchers at the University of Arizona Cancer Center in Tucson reported last week in the New England Journal of Medicine that cells from a patient’s cancer can be grown, or cultured, in the laboratory and tested there to determine which drugs work.

Researchers have long been frustrated by their inability to get cancer cells from patients’ tumors to grow rapidly in culture. But the Arizona team, led by Dr. Sydney Salmon and Cell Biologist Anne Hamburger, discovered three years ago that by “conditioning” culture medium with spleen cells taken from mice prone to cancer, they can grow tumor cells from people with common forms of cancer. (The mouse cells apparently produce some yet unidentified factor that supports the growth of certain human cancer cells.) According to Salmon, the cancer cells that thrive and form colonies in the laboratory’s plastic petri dishes appear to be the tumor’s “clonogenic,” or “stem,” cells. Though they account for less than 1% of all the cells in a tumor, these cells are thought to be the cancer’s key replicating units; they divide and migrate, “seeding” new cancers in the body in a process called metastasis.

The Arizona team began applying anticancer drugs to cells taken from tumors and then culturing the cells in order to, in their words, “determine whether there are correlations between what is observed in the petri dish and in the patient.” Tumor cells taken from nine people with myeloma, a bone marrow malignancy, and nine with ovarian cancer were exposed to varying concentrations of several anticancer drugs, then cultured in petri dishes. The researchers compared the effects of the drugs on the cultured cells with the patients’ responses to the same drugs. In all but one case, the effects matched. If the drug prevented cancer cells from growing in the culture, it also killed them in the patient. If the drug had no effect in the petri dish, it did not help the patient. The team also found that while patients might have the same type of cancer, their cells in culture showed markedly different responses to the same drug. Sometimes sensitivity to a drug varied by a factor of 20 or 30.

The main value of the laboratory test, says Salmon, is that it can help the physician plan individual courses of treatment. For example, only 20% of people with cancer of the colon or rectum respond to the drug fluorouracil; the other 80% suffer needlessly from the drug’s toxic effects. The new technique may have another benefit: it could be used to evaluate new anticancer drugs without endangering cancer patients.

The researchers stress that at least three years will be needed to verify and refine the technique. Says Salmon: “This is not now a clinical test available in every hospital. Until it has had adequate testing, it should be considered only a promising research tool.” Still, that promise is exciting. A Journal editorial accompanying the paper notes that “an effective and practical predictive test for antitumor agents would have a profound effect on the treatment of cancer.”
