    Getting Smarter by the Day: How AI is Elevating the Performance of Global Companies TCS Global Trend Study: Part I Contents Executive Summary and Key Findings 4 AI in Action at Big Companies in Four Regions of the World 12 Case Study: AI at AP 24 AI Spreads Beyond IT to Other Functions 29 Case Study: At Microsoft, AI is a Big, Big Deal 41 How Leading Companies Use AI 45 Case Study: Cloudera’s Formula 55 Research Approach and Demographics 58 Executive Summary and Key Findings AI Goes Mainstream After about 50 years of largely languishing in technology labs and the pages of science fiction books, today artificial intelligence (AI) has taken center stage and is under the bright lights. Barely a day goes by without dozens of new magazine and newspaper articles, blog posts, TV stories, LinkedIn columns, and tweets about cognitive technologies. It shouldn’t be at all surprising. The impact of AI has been very upfront and highly personal these days. The technology is beginning to reshape the jobs people hold, the cars they drive, the medical procedures they undertake, and the games they play. Nearly 20 years after IBM’s AI computer system beat Russia’s chess champion, AlphaGo, an AI program created by search engine giant Google defeated a grandmaster of the popular Southeast Asia board game, Go, in 2016. Go was considered to be a far more complex game for a computer to beat than chess.1 A robotic surgeon stitched up a pig’s intestines better than the doctors assigned the same job.2 Even articles in the business pages are being written by AI software, as you’ll see in our case study on the global news service, the Associated Press.

  • A Dozen Ways Insurers Can Leverage Big Data for Business Value 290413
    White Paper A Dozen Ways Insurers Can Leverage Big Data for Business Value The amount of structured and unstructured, internal and external data coursing into every organization is voluminous and increasing exponentially. Data today comes from disparate sources that include customer interactions across channels such as call centers, telematics devices, social media, agent conversations, smart phones, emails, faxes, police reports, day-to-day business activities, and others. Gartner’s 2011 Top 10 list of IT Infrastructure and Operations Trends predicts an 800 percent growth in data over the next five years 1. Organizations actually process only about 10 to 15 percent of the available data, almost all of it in structured form. While managing this overwhelming data flow can be challenging, insurers can reap very real benefits like increased productivity, improved competitive advantage and enhanced customer experience by capturing, storing, aggregating, and eventually analyzing the data. This value does not come from simply managing big data, but rather, from harnessing the actionable insights from it. Insurers that can glean objective-driven business value by applying science to their data and deriving insights will maintain a competitive advantage and stay ahead of the curve in this information age. About the Authors Ajay Bhargava, Director, Analytics and Big Data, TCS Ajay Bhargava has more than 23 years of industry, research, and teaching experience in areas relating to Databases, Enterprise Data Management, Data Warehousing, Business Intelligence, and Advanced Analytics. Over the years, he has provided business and technology-oriented strategic, mentoring, and customer-centric solutions to his clients.
