Practical Examples

1. Presenting data in context

   Rather than showing raw figures, Duarte advises situating data within a broader narrative. For example, a sales analyst might not simply report a 20% drop in Q4, but connect it to industry trends and prior performance, helping leaders see both the 'why' and 'what next'.

2. Creating a 'Big Idea' statement

   Duarte recommends crafting a single, clear statement that captures the core insight of the data. For example, 'Customer engagement is trending downward because response times have increased,' which guides the narrative and keeps the audience focused.

3. Using contrast to highlight key points

   Instead of only presenting positive outcomes, Duarte suggests showing the gap between current and desired states. For example, compare current customer satisfaction scores with target benchmarks, making the need for action more compelling.

4. Building slides with visual hierarchy

   Duarte emphasizes arranging visual elements so that the most important insights stand out, such as making critical numbers bold or using color to emphasize trends. This ensures that busy executives immediately grasp essential points.

5. Advocating for data-driven decisions

   She provides scenarios where analysts not only report data but also recommend specific actions. For example, an analyst might conclude a presentation by outlining three targeted steps to address a sales decline, translating insights into tangible strategy.

6. Framing consequences of inaction

   Duarte counsels presenters to highlight what will happen if current trends continue. For instance, if a cost overrun persists, its impact on future project funding is addressed—making abstract risks concrete.

7. Personalizing data for relevance

   Duarte illustrates tailoring messages to different stakeholders. A CFO cares about bottom-line impacts, while a product manager values customer feedback, so data is reframed for each audience’s priorities to maximize influence.

8. Editing for clarity, not just accuracy

   She shows how simplifying complex charts and removing extraneous details can prevent information overload. For example, a busy waterfall chart is distilled into a clear before-and-after story, making the takeaway obvious.
