1. Do you have any method of creation, prioritization and use cases?
well, it depends "heavily" on the business requirements. we have to make too many meetings with client stakeholders and understand their requirements, purpose, the business value they are looking for, from the splunk environment, etc.. would provide you the ideas automatically, for "any method of creation, prioritization and use cases"
2.How to document your use cases? What tool do you use?
Use Cases are simply a word/pdf document, which will show us the business requirement and how the tool/solution would resolve the issues/problems we would face when we implement the business requirements. Sooo, no special tools, as of my knowledge. thanks.
3.Did you use any framework or process for this action?
no framework as per my "limited" knowledge. Simple enough - understanding the clients and stakeholders will make the job easier for you. thats all from my side. thanks.

PS - Your karma points will be my 2 cents, thanks.
