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.

The Hittites of northeastern Asia Minor (2000-1200 B.C.) did the trick well. Their archives, written in cuneiform characters on baked clay bricks, were dug up in 1906\. The records gave scholars the Hittite view of late Bronze Age politics. The Hittites, said the Hittites, were lords of all they surveyed. As the scholars read more of the bricks, they found that the Hittite archives had not been thoroughly screened. In them were records of campaigns not convincingly triumphant. There were even official letters from a powerful nation, Arzawa, which had matched the Hittites blow for blow. Except for these few clues, however, Arzawa vanished from history. Champagne Glass Trail. Archaeologist Seton Lloyd, director of the British Institute of Archaeology in Ankara, tells in the Scientific American how British diggers uncovered Arzawa. First, Student James Mellaart reconnoitered southwestern Anatolia, looking for mounds, stones and bits of pottery. Some of the potsherds could be fitted together into graceful drinking vessels like champagne glasses. They led Mellaart, like bits of paper in a paper chase, to the centers of the long-forgotten culture, southeast of Istanbul. A full-dress expedition followed and attacked a promising mound called Beycesultan on the headwaters of the Meander\* River. First find was archaeological peanuts: a Byzantine town about 2,000 years younger than Arzawa. Under the Byzantine ruins, the diggers uncovered a row of small houses that had been destroyed by fire. Mixed in the ruins were the telltale “champagne glasses.” The first bit of Arzawa had come into the sunlight. As the diggers extended their trenches across the mound, they found an enormous mass of burned limestone and brickwork. It turned out to be a palace, whose plan suggested in some ways the sophisticated civilization of Knossos on the island of Crete. The diggers speculated that when Knossos was destroyed by the Mycenians (Homeric Greeks) about 1400 B.C., a Cretan architect may have escaped and plied his trade among the Arzawans. In any case, the Arzawans were no barbarians. At one entrance of the palace was a kind of bathroom, where visitors washed themselves before making their bows at court. One odd feature of the inner chambers: floors raised about a yard above the ground. Beneath the floors were small passages. They suggest air ducts of a heating system, but nothing of the sort is known to have existed until 1,000 years later. Bronze-Age Bar. The palace was well looted when it was burned, but smaller structures built on its ruins were destroyed without looting. Most interesting was a row of little shops. One was a Bronze Age pub with sunken vats for the wine supply and a lavish supply of glasses for serving the customers. It also had knucklebones, a gambling game that did the duty of a modern bar’s chuck-a-luck. Only a fraction of the Arzawan ruins have been dug up so far, and archaeologists are eagerly awaiting the final results. The Arzawans could write (on clay bricks), and presumably they had archives. If archives are found, scholars may learn what the Arzawans thought about the loudmouthed Hittites, who defamed them in cuneiform 3,100 years ago. In Plateau, published by the Museum of Northern Arizona. William C. Miller of Mount Wilson and Palomar Observatories reported a novel collaboration of astronomers and archaeologists. Miller’s avocation is to look for Indian remains in Arizona, and he was immediately interested when a survey party from the Museum of Northern Arizona found two Indian rock drawings, each showing the crescent moon and near it a large round object. Crescents are rare in Indian drawings, and the round objects were hard to explain. Miller discussed the drawings at his observatory, and visiting Cosmographer Fred Hoyle of Cambridge University, England had a bright idea. Maybe, suggested Hoyle, the large object in the drawings is the supernova\* of A.D. 1054, the enormously brilliant “new” star that outshone all the other stars in the sky and was plainly visible in daytime. Europe was too backward in astronomy in 1054 to pay much scientific attention to the event, but Chinese and Japanese astronomers recorded it accurately. The supernova appeared over China on the morning of July 4, 1054, and its position was close to the bright star Zeta Tauri. The Indians of the U.S. southwest must have seen the supernova too, said Hoyle, and they may have recorded it in their rock inscription. Right Answer. To check the theory, Miller got help from Astronomer Walter Baade of Mt. Wilson and Palomar, who computed the phase and position of the moon at the time when the supernova could first have been seen in Arizona. The answer came out right. The moon was a crescent, as drawn. In northern Arizona it would have risen shortly before dawn on July 5th, and the supernova would have been close to it. The sight must have been striking; the supernova was probably the brightest object, other than the sun, ever to be seen by historic man. Miller’s next step was to find out whether the sites could have been occupied by Indians in A.D. 1054\. At one site (White Mesa) he found a few potsherds that probably date back 900 years. At the other site (Navaho Canyon), a deep cut in the canyon floor exposed a great number that are as old or older. Properly cautious, Miller says: “The rather stringent conditions for a favorable answer seem to be met and strongly suggest the possibility that the two pictographs actually depict . . . the supernova of A.D. 1054.” \*Now called Menderes, the winding Meander of Greek times was the origin of the modern word meander. \*Massive stars that explode suddenly, turning most of their matter into a burst of radiation. In the Milky Way galaxy, they appear roughly once in 500 years. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6609689/science-diggers/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6609689/science-diggers/"},"headline":"Science: Diggers","datePublished":"1955-07-11T04:00:00.000Z","dateModified":"2026-02-26T04:53:36.342Z","description":"The way for a nation to keep its memory bright, say archaeologists, is to write its records on durable material which will eventually be found.
