• Trade-Off between VV&A Project Needs & Constraints• Trust vs. independence vs. costs vs. risks vs. impact…

• Depends on M&S Product Composition• Not all M&S Components are Equally Critical or Have Same Impact

• Types of VV&A Assessment Required • SV&V => Supplier does all V&V for Costumer• IA => Supplier does V&V but 3rd Party Assess the work for Costumer• IV&V => 3rd Party does all V&V for Costumer

• Party Selection Criteria• Trustworthiness, Experience, Recognition Level,…

• Actor Selection Criteria• Activity/Task Specific Skills, Knowledge, ….
