As awareness of the Internet of Things (IoT) grows, devices are becoming smarter and more embedded, resulting in difficult development environments. But as with any software, there is a demand for it to be delivered fast, and that goes for embedded devices—despite their complexity.

“Software has become the primary driver of innovation and disruption,” said Anders Wallgren, CTO of Electric Cloud, at this week’s Agile2015 conference in Washington. “To stay competitive, we have to deliver better software faster.”

Normally, to gain that competitive edge and deliver high-quality software rapidly, organizations have turned to using agile, but it’s not enough, according to Wallgren. He explained that while agile is all about the end-to-end process, it stops at engineering and doesn’t follow through after the software is pushed into production.

“I don’t want to call agile a solved problem, because it clearly isn’t,” he said. “What happens to that software after we are done delivering it…the software you ship on Day 1 is not the software that is going to live on that device forever.”

And that software becomes even more important in IoT devices because developers have to build software that is accessible from anywhere, as well as to continuously deliver frequent over-the-air updates, according to Wallgren.

“The expectation really is very different than what it used to be,” he said. “The expectation was I buy something, and it has software, and that software is for life. Now the expectation is no, you are going to fix that bug. The job of the software team is not done when you ship the device.”

Wallgren explained that IoT is the new embedded; it’s a transformative technology, and a new way of delivering that technology is necessary.
