分析：agree! it's too high level. it has to make detail plan. and add the buffer on it. specially at the second point, it should be come in to 3 steps. a- system arch (hardware, network topology, loading-balance,distributed) b- interface design (class name and relationship) c- the test case( use case, scenario)
The third point is too naive. there are must be reviewed and set milestone.
finally, I have no found the bug fixed time reserved.
