Scrum drill (3)

At Wednesday, a still has not completed the task, B has completed the function design, and C has encountered difficulties in development.
The function design of B was discussed in a group on Tuesday. The work of 1D is calculated as C as 0.5d. The burning diagram goes down to 1.5D.
A promised to complete the task today. B asked for leave on Thursday and Friday to find a task that can be completed within one day. C continued to attack the difficult problem and asked for help.

At the meeting on Thursday, a completed the database design, and C had not solved the problem.
If a calculates 1D and B's task completion is not well estimated, it will be calculated after he returns. The burnout chart goes down to 1D.
A started a new task. The coding and testing of the Dal layer, C's task is a difficult problem, so I had to try the water by myself.

Both meetings were completed within 15 minutes. After all, they asked about the tasks of three people. I feel that I have not done much communication. The time is up.

Meeting on Friday, a is writing a testCodeWhen the test is complete, the progress is low, the C problem is not solved, and the D test is not solved.
There is no solution to the problem. C started the design of another scheme, and a continued to write the dal and test. The burnout diagram does not go down.
