We are currently doing Scrum in a trading environment, our sprints are a week long, the problem is that due to Change requests from trading activity during the sprint it is impossible to have a sprint backlog that is protected. The sprint backlog often gets changed mid week leading to it becoming a waterfall timeboxed sprint.
I am now not sure if Scrum is the right approach but keen to set this project up so that it is run in an agile way, what would you recommend? Thanks
