Create a 9-slide consulting presentation for the management board of [client], presented by [firm] on [date]. Slide 1: cover with the project name, the audience and the date. Slide 2: executive summary with the recommendation in one sentence including its number, the situation in two sentences and the decision we ask for. Slide 3: a waterfall chart that bridges [metric] from [year] to [year] across [four drivers], with a two-sentence takeaway. Slide 4: the four causes behind those drivers, each with one number and what [client] can change. Slide 5: a matrix of [number] candidate measures by impact and effort, with the selected ones highlighted. Slide 6: a table comparing three options (A, B, C) on [effect], [one-off cost], [payback], ease of execution and customer risk, with B marked as the recommendation. Slide 7: a roadmap with the workstreams over [number] quarters and a checkpoint after 90 days. Slide 8: the business case with one-off cost, yearly effect, payback and the effect on [margin], with the assumptions in a note. Slide 9: the decisions we ask for today, each with an amount, a name or a date. Write every title as a full sentence that states the finding. Use my real figures; where one is missing, mark it as an assumption instead of inventing it.
