The RINGI Technique is method in which a document with solutions is passed along the table, comments are individually written and a final solution is selected based on the comments.
Originally, this document was purposed to go through different hierarchical layers of a company, so that everyone involved could influence the decision.
Executing the Method
Have a document with all solutions listed, for example a large sheet with all alternatives on post-its.
Write Down Comments
Let everyone write their comments for each alternative down on the sheet. This can be done one by one, but also by multiple persons if you are using a larger sheet.
Review and Discuss
Review all the comments for alternatives, and discuss which alternative is most preferred.
