This chapter provides a detailed description of how iteration is used in the MIRA open solution approach to foster trans-disciplinary learning. This approach culminates in a consensus decision that is supported by a comprehensive evaluation of various types of uncertainty and how they relate to Decision Uncertainty. After performing the Baseline Run in Chap. 4, stakeholders are ready to proceed with further experimentation via iteration runs to better understand alternative rankings. This chapter describes those aspects of MIRA that makes it a practical open solution process. The process maximizes the use of these iterations until an analysis is produced with acceptable Decision Uncertainty, as determined by the stakeholders. The Gaia example used in Chap. 4 is expanded in Chap. 5 to illustrate the strategies and analysis methods used in a realistic MIRA application.
