As you may all agreed the sprints are not going as expected always.
What you should do as a scrum master when you see the trend of the remaining work line going up in the middle of the sprint? here are the circumstances
- There a is task of 10 points and the assigned developer not be able to even start.
- No other developer in the team also not able to help him and only one week to end the sprint.
here are the possibilities I'm thinking right now, but you always welcome to come up with a better one.
