An agile team wants to gather data during retrospective but is not able to do it effectively. Team approached Sam, the scrum master of the team. Sam suggested few techniques which would help in generating data. All of the following techniques would be helpful except:
a. Timeline
b. Satisfaction Histogram
c. Team Radar
d. Helped, Hindered, Hypothesis
Helped, Hindered, Hypothesis is being used in the closing stage of retrospective in which we list down what helped during the retrospective, what were the hindrances and what hypothesis we would adopt in future retrospectives to make it more effective.
