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.

Since the 1920s, dozens of archaeological expeditions have unearthed traces of a 4,500-year-old urban culture that covered some 300,000 square miles in modern-day Pakistan and northwestern India. Digs at major sites such as Mohenjo-daro and Harappa revealed a sophisticated society whose towns had advanced sanitation, bathhouses and gridlike city-planning. Evidence of trade with Egypt and Sumer in Mesopotamia, as well as the presence of mining interests as far as Central Asia, suggests that the fertile Indus River basin could have been home to an empire larger and older than its more famous contemporaries in the Middle East. But the Indus Valley civilization poses an intractable problem, one that legions of archaeologists and scientists have puzzled over from the first excavations to a new study published last month. Its writing, etched in signs on tiny, intricate seals and tablets, remains undeciphered, shrouding the ancient culture in mystery. A code-busting artifact with bilingual text, like the Rosetta stone, has yet to be found. By some counts, more than 100 decipherments of the civilization’s often anthropomorphic runes and signs — known in the field as the Harappan script — have been attempted over the decades, none with great success. Some archaeologists spied parallels with the cuneiform of Mesopotamia. Others speculated an unlikely link between Harappan signs and the similarly inscrutable “bird-men” glyphs found thousands of miles away in the Pacific Ocean on Easter Island. In 2004, perhaps out of befuddlement and frustration, a group of scholars declared that the script marked only rudimentary pictograms and that the Indus Valley people were functionally illiterate. That hypothesis, which caused a minor uproar in the world of Indus Valley researchers, was recently rejected by a team of mathematicians and computer scientists assembled from institutions in the U.S. and India. That team’s study, published initially in April in _Science_ and more extensively in August in the _Proceedings of the National Academy of the Sciences,_ employed computer modeling to prove that the Harappan script communicated language, and has reinvigorated attempts to crack what is one of the lingering puzzles of ancient history. The group examined hundreds of Harappan texts and tested their structure against other known languages using a computer program. Every language, the scientists suggest, possesses what is known as “conditional entropy”: the degree of randomness in a given sequence. In English, for example, the letter _t_ can be found preceding a large variety of other letters, but instances of _tx_ and _tz_ are far more infrequent than _th_ and _ta._ “A written language comes about through this mix of built-in rules and flexible variables,” says Mayank Vahia, an astrophysicist at the Tata Institute for Fundamental Research in Mumbai who worked on the study. Quantifying this principle through computer probability tests, the scientists determined that the Harappan script had a similar measure of conditional entropy to other writing systems, including English, Sanskrit and Sumerian. If it mathematically looked and acted like writing, they concluded, then surely it is writing. But this is just a first step. Vahia and his colleagues hope to piece together a solid grammar from the sea of impenetrable Indus signs. Their August paper charted the likelihood of certain characters appearing in parts of a text — for example, a fish sign appeared most frequently in the middle of a sequence and a U-shaped jar sign toward the end. Bit by bit, the structure of the script is coming into view. “We want to find the bedrock against which all further interpretation of the language should be checked,” says Vahia. Down the road, he imagines he could write in “flawless Harappan” — even though he may have no idea what the assembled sequences would mean. Rajesh Rao, an associate professor of computer science at the University of Washington and a co-author of the study, says the task ahead of them is “like a jigsaw puzzle, one where you try to fit meanings into patterns and sequences.” At the moment, he and his team are wary of ascribing meaning to the signs — an act of conjecture, he says, that has led other Indus Valley experts in the past “to go too far.” It doesn’t help that, though long dead, the Harappan script sparks sometimes acrimonious debate in India over the nature of its origins. Scholars from southern India claim it ought to be linked to proto-Dravidian, the progenitor of languages like Tamil, while others think it is related to the Vedic Sanskrit of early Hinduism, the ancestor of Hindi and other languages spoken in India’s north. And while cultural agendas within India have stymied collaborative efforts, the enmity between India and Pakistan has impeded archaeological breakthroughs. Ganeriwala, a desert site in Pakistan that possibly holds the ruins of one of the civilization’s biggest cities on record, has yet to be properly excavated because it sits precariously along the heavily militarized border with India. [(See pictures of Kashmir.)](https://www.time.com/time/photoessays/2008/scars%5Fkashmir/) More the shame, says Bryan Wells, a senior researcher at the Institute of Mathematical Sciences in Chennai, for solving the riddle of the Harappan script needs the involvement of people from all backgrounds. Wells, who was not part of Rao and Vahia’s team, spent 15 years painstakingly examining the disparate body of Indus Valley artifacts and compiling what is now the largest database of Harappan signs — 676 in total. Even though no one knows the root language behind the script, he reckons greater cooperation and a monkish devotion to the task can slowly unravel more secrets. Wells and a colleague have already made significant progress in decoding the Harappan system of weight measurements. “What you need is to keep an open mind, form a good idea and have others break it apart and expand it,” he says. That process of careful scientific analysis and scrutiny will take years, probably decades. But it would be worth the wait. Scholars aren’t even sure how this enigmatic civilization disappeared. Was it eradicated by conquest or washed away by floods, or did its people just blend into other migrations settling the Indian subcontinent? Although Harappan cities were vast — Mohenjo-daro could have been populated by as many as 50,000 people, a staggering figure for such deep antiquity — they have left behind few towering monuments or epic ruins. Instead, we have clues in miniature, a copper figurine of a mercurial dancing girl, for example, and a treasure trove of delicately carved seals, most no larger than a postage stamp. “They are a window into how these people were thinking,” says Vahia. “And they can tell us, in a sense, why we are who we are.” [See TIME’s Pictures of the Week.](https://www.time.com/time/picturesoftheweek) [See the Cartoons of the Week.](https://www.time.com/time/cartoonsoftheweek) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6947830/decoding-the-ancient-script-of-the-indus-valley/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6947830/decoding-the-ancient-script-of-the-indus-valley/"},"headline":"Decoding the Ancient Script of the Indus Valley","datePublished":"2009-09-01T04:00:00.000Z","dateModified":"2026-03-15T21:09:38.612Z","description":"The ancient cities of the Indus Valley belonged to the greatest civilization the world may never know.
