The Drupal ecosystem alongside with other open source technologies provides a toolset that is extremely valuable in the process of product development.
The best approach I've found to product development is to build a Minimum Viable Product (MVP) in the shortest possible time and get feedback from potential users early in that process. Drupal gives us everything to follow this path. High-quality contributed modules, the development framework through both the contrib space and Drupal core itself, and the extremely helpful community behind this technology are all leading to success.
I had the opportunity to see this power while I developed products as a member of the Products team at Commerce Guys, as well as launching my own startup over the past couple of months.
Come to this session to hear about my experience in this process, how to make both technical and non-technical decisions, and how to deliver the right things at the right time.
