Audience task: understand the material service change, judge evidence and uncertainty, compare initiatives 1/2, then decide funding. The current deck asks them to decode 72 KPI cells, three charts, five causes, six initiatives, and repeated prose in eight minutes.
Blockers: slide 2 is unreadable at 9 pt and narration duplicates visual search; move the full table to appendix and show only decision-relevant KPI changes with readable source labels. Slide 4 carries five uncertain causes plus prose and diagram; split into “observed failure path” and “causes remain hypotheses,” or keep only the two causes relevant to initiatives 1/2. Slide 6 forces comparison of six options although only two are in the decision; move options 3–6 to appendix and make a two-column comparison preserving cost/dependencies.
High load: slide 3 needs assertion title and one highlighted trend; other charts move to appendix. Slide 5 keeps 71% (96/143) and night shift 50% (18/39) as two visual callouts; move quotations/method to notes/appendix, but retain representativeness limit on slide. Slide 1 reduces to purpose, evidence path, decision—not nine bullets. Remove decorative fades if they delay access.
Revised 7-slide map/time: 1 purpose/decision 0:30; 2 service risk 1:15; 3 relevant trend 1:00; 4 evidence and root-cause uncertainty 1:15; 5 customer subgroup evidence 1:00; 6 initiatives 1/2 comparison 1:30; 7 exact decision/conditions 1:00; 0:30 buffer. Fidelity: required denominators, sources, costs, dependencies, and uncertainty remain; detail moves to appendix rather than tiny text.
