Consulting Case interview Question help!

Can anyone lay out the framework/structure for this consulting case interview question? It's about PMI. I'm stuck!! : Two companies in the financial service industry have recently merged. You will be addressing the boards of these two companies regarding their upcoming IT integration strategy and have the opportunity to interview the CEO’s of each company involved. What key information would you like to ask the CEO’s to prepare for the board meeting and what will you likely discuss?

Also, how would you lay out your structure for PMI questions in general?
