Help Me Create A Case Study Template

I’ve received a good amount of feedback from folks asking me to generate case studies on the use of WordPress when it comes to large scale use or heavy modified development. I’d love to do these case studies to find out the particulars on how WordPress is used in certain situations but the problem is, I don’t know how to go about it. This idea has been circulating around thanks to John M when he made a thread about it in the forum. Personally, I would like to create a questionnaire that can be sent to these people but I’m not sure if that is the correct way to go. Furthermore, I don’t know which questions to ask when it comes to a case study. This is where I need your help. If you have ideas, questions, or anything of that sort, please post in that forum thread or here in the comments.
