An important goal of the study is to develop community consensus on the key questions that need to be addressed in this area (i.e., can we agree upon the set of questions that, if answered, would make a significant difference?). These questions should provide guidance for research and priorities for funding. 

We need several kinds of input on these questions:

 * Are there important general directions not covered by these questions (i.e., what other questions should we be asking)?

 * For each of the question themes identified: how do we best formulate the top-level question?

 * Each of these questions is very broad.  We should work on articulating appropriate sub-questions.

 * Many of these questions are likely to have partial answers or have research that illustrates issues in the question.  Please help us annotate the questions with appropriate research (patent, product?) links.
 

 Please contribute and help to formulate, refine, focus, and prioritize these questions as well as identify any additional questions.

== Questions ==

 1. [[Questions/Q1|How do we organize, manage, and analyze layering for cooperative fault mitigation?]]
 2. [[Questions/Q2|How do we best accommodate repair?]]
 3. [[Questions/Q3|What is the right level of filtering at each level of the hierarchy?]]
 4. [[Questions/Q4|Can we establish a useful theory and collection of design patterns for lightweight checking?]]
 5. [[Questions/Q5|What would a theory and framework for expressing and reasoning about differential reliability look like?]]
 6. [[Questions/Q6|Can a scalable theory and architectures that will allow adaptation to various upset rates and system reliability targets be developed?]]

Discussion on ideas for writing questions is on [[Questions/Brainstorming|this page]].
