                         development effort. The integration readiness levels (IRL) scale 
                         complements technology readiness levels (TRL) to assess the system 
                         development maturity, representing risk levels for integrating 
                         technologies in a system. The increasing complexity of systems, 
                         due to multiple interfaces and an information-centric 
                         architecture, demands new systemic approaches to analyze the 
                         architecture and communicate IRL assessments. Therefore, this 
                         article developed a methodology to apply IRL using architecture 
                         views through the design structure matrix and domain mapping 
                         matrix. A case study analyzed technology introduction impacts and 
                         different integration strategies for space systems from 
                         China-Brazil Earth Resources Satellite program at the system and 
                         system-of-systems levels. Through the design science method, 
                         results show the pragmatic evaluation and validation for the 
                         proposed method and for the IRL scale itself, by professionals of 
                         the case study projects. The research draws suggestions for 
                         holistic system analysis and managerial communication applications 
                         using the proposed method and suggests a rationale for IRL
