The author reflects on their experience in software development, starting with a traditional Waterfall approach where development, testing, and operations teams worked in silos. They then transitioned to an Agile methodology, which introduced more collaboration between teams and the use of continuous integration and testing. The author's startup, focused on solving software testing problems, further accelerated this process by releasing code to production quickly, often daily, and using fast feedback systems to inform development decisions. This approach has led to a faster release cycle, improved process efficiency, and increased reliance on collaboration between teams.
