GInI’sCInP Handbookdescribes brainwriting as a common brainstorming technique where participants begin with quiet, individual idea generation—writing down thoughts before group discussion. This method, often called "silent brainstorming," ensures diverse input, reduces groupthink, and builds a foundation for collective ideation. The question’s phrasing—“quiet time for individual brainwriting”—explicitly points to this practice. Option A, "problem review," is preparatory, not generative. Option C, "sketching," might occur but isn’t the standard term. Option D, "reflection," is introspective, not idea-producing. Option B aligns with GInI’s methodology, where brainwriting kickstarts creativity systematically. The original answer (B) is correct, supported by GInI’s emphasis on structured, inclusive ideation techniques that maximize participation and output.
