Our agile sprint lasts three weeks. Say 40*3 = 120 hours. Our boss requires us must to log at least 8 hours every day. We use JIRA to record time. However my current story in the sprint estimated time is about 15 hours, of course it is not enough. Because I have to search online, discuss with team members and watch training videos etc. But even so I still can't log the whole time 120 hours. Be honestly, I am a quick problem solver, maybe I can use 40 hours to finish the project. After I finish my job, I can learn new technology related to the sprint project by myself.
The thing is if I logged more time on the agile project, the burn down chart would be ugly. If I logged less time to the project, my boss would be angry too, why do you spend much time on training rather than direct sprint work?
The terrible thing is that I heard that the performance would be related the time tracking.
So please advise me a right direction for time tracking.
