The term “Moscow technique” doesn’t seem to refer to a specific, universally recognized concept in any domain as of my knowledge cutoff in September 2021.
If you’re referring to a specific technique, concept, or method within a specific field (such as project management, negotiation, sports, etc.), please provide additional context.
One possibility might be that you’re thinking of the “MoSCoW method” in project management, which is a prioritization technique used in business analysis and software development to reach a common understanding with stakeholders on the importance they place on the delivery of each requirement. The term MoSCoW itself is an acronym derived from the first letter of each of four prioritization categories: Must have, Should have, Could have, and Won’t have. This method helps stakeholders understand which requirements are negotiable and which are not, aiding in effective project scope management.
