回複：祝大家新年快樂！問個不和諧的問題：這個黑鍋俺咋能不背？

胡說之, veggiedoggie, cathybay offerred pretty good points, 

some extra questions for you to mull:

1) regading "選平台的問題":

what are your competitors' platform?

what is the benchmark of such plaform in your industry.

what is the justification to choose this platform.

2) 總體設計

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.
