I made a small list of questions that I feel are important to ask from a project team before diving deeper to any mobile project. List goes like this: 

• Is solution needed regularly or does it contain information that changes frequently?
  
• Do technical requirements match with target group?
  
• Can you make it any simpler, please?
  
• How to publish the solution?
  
• Is it visual?
  
• Well, how much does this cost?
  

Complete list is available from my personal site.

I also set up a custom search engine for mobile developers, you can access it from search.mobilitics.net. Idea is that search engine only uses sites that have been most important for myself when trying to solve mobile development related problems. There is also information available what to do is you want to contribute to make engine even better.
