GInI'sCInP Handbookexplains that post-selection in InMS Stage 3, concepts move to Stage 4, where development includes creating a "preliminary business plan/business case." This document outlines the concept's value proposition, market potential, and initial financials-enough to justify further investment without full detail. It's a Mid Zone activity, bridging evaluation to execution. "New hypotheses" (A) is Front End, pre-selection. "Detailed design" (B) is Back End, post-business case. "Fully-detailed forecast" (D) is overly precise for this stage-GInI seeks preliminary viability, not 95% confidence yet. Option C aligns with GInI's process, matching the original answer (despite typo), reflecting a pragmatic step to validate concepts strategically-a GInI method for staged commitment.
