Preparation
With 30 minutes, spend about 10 on reading and defining the problem, 10 on two or three solutions with evidence and 10 on structure and silent rehearsal. Present problem, cause, solution and impact, stating your conclusion first. Q&A; often probes feasibility and cost; acknowledge limits and offer fixes.
