A scrum or sprint is more of a small scale development trajectory within a larger, industry-wide development process.
It is great for gaining a lot of motivation, developing a strong team and strong concepts as well as requires to do a lot of research and in my experience, doing extra hours. Especially for tackling complex problems, a scrum works great. Then to implement it you need to switch back to longer-term planning and co-operating with departments that work more ‘A to B’ style. For product design in my experience it is fruitful to do a pressure cooker/scrum once every 6-8 weeks with the rest being regular development work.
