Our company adopted the Agile scrum process for interface design and programming in 2007. It was the hot thing then. We borrowed some of the elements for a somewhat complex and fast-track hardware product, including the morning stand-ups, stories, priority/workload ranking, and multi-disciplinary small project teams. We didn’t have a dedicated scrum master. It worked very well, although it wasn’t a full Agile adoption, more like ‘best practices’ that any product development group could implement.
Keeps everyone more accountable and engaged through the project, compared with the standard ‘waterfall’ where people can see 2 months of downtime ahead of them and thus do nothing.
