回复：祝大家新年快乐！问个不和谐的问题：这个黑锅俺咋能不背？

胡说之, veggiedoggie, cathybay offerred pretty good points, 

some extra questions for you to mull:

1) regading "选平台的问题":

what are your competitors' platform?

what is the benchmark of such plaform in your industry.

what is the justification to choose this platform.

2) 总体设计

similar questions to the above.

check if there is a chief architech in your company,

sneak view with him, and get align with him

I like Kathy_bay's idea, with which you might rise quickly if you are risk taker and your homework is solid.
