Which scenario approach is worth using for this decision? Cordova-Pozo and Rouwette’s 2023 review of reviews distinguishes scenario approaches and their construction and effectiveness questions. Adapt its method-selection lesson in sections 4.2–4.4: choose coherent, decision-discriminating conditions instead of requiring one two-axis technique. The serious lower-effort alternative is a justified single forecast or direct conditional comparison. Use it when additional scenarios would not change the decision. The review supports a reasoned method choice, not a guarantee that this scenario exercise will improve performance.
For choice when model or future agreement is unavailable, adapt the robust-decision line discussed by Lempert and colleagues in 2024: preserve consequential conditional information and examine failures across futures. This changes section 4.4’s shared-failure question and section 4.5’s qualified return. Its climate-assessment setting supplies methodological support with a transfer limit; it does not establish probabilities for SensorCo.
Could another participant’s response defeat our move? Use backward induction only where its finite, complete/perfect-information model and rationality assumptions fit the question. Muhamet Yildiz’s 2012 notes, reused in MIT’s Fall 2025 course, explain the later-to-earlier comparison and commitment contrasts in chapter 9, sections 9.1–9.5, with subgame and information-structure limits in chapter 11, section 11.1. This established Method informs section 4.3 and the provider case; current teaching reuse is not empirical evidence that real participants obey the model. A sufficient existing response account is the lower-effort alternative. Different information or behavioral premises require an appropriate qualified result.
Reopen this choice of method when a new mechanism defeats coherence, a new condition changes action, a sufficient forecast becomes available or maintaining the set costs more than its attainable decision contribution.
