亲身经历+John的点拨。

- who is the right resource at the righ time?
The most skilled person may not be available. He is busy for lot of stuff. To answer your questions, do you need the most experienced person or somobody who knows it? Igrashi-san is difficult to consult now, but how about MM?

- to understand your customers
The customers always have voices. The dagnerous thing is they do not have voices. Just listen and understand why they need this and that. Their solutions are reference. You are the right person to drive the final decision to meet the requests not requirements.
