There are more than 1.4 billion smartphones in the world—one for every 4.5 people on earth. Over the next decade wearables and the Internet of Things (IoT) will make those numbers look puny. In fact, mobile is transforming how people and things connect and dramatically changing software development, as we know it. With more than 189 million apps downloaded daily from app stores and new IoT devices being released daily to the public, developers and testers are already behind the curve. James Montemagno takes a look at the problems and challenges we face today and what we can look forward to in the future. Explore how the ever-growing number of devices and connections will force companies to produce efficient mobile-first products to move ahead in the market. Take back ideas and action items to start tackling the immense fragmentation of devices in the marketplace and identify the steps necessary to transform your development/test teams, environment, and processes to survive and prosper in this brave new world.
