This is the name of a summary page using combined elements from data-driven and conceptual chart objects that you can base an entire conversation on. It could be one central concept, a filled-out framework, or a summary of your data (e.g., a dashboard).
It’s a great idea to use a killer page, also known as an anchor chart, when you don’t want to bring in a huge PowerPoint deck. You may only want to discuss one or two concepts.
These pages are especially helpful if you leave an interactive element to the page, such as boxes to check off during an interview, boxes to fill in, etc.
Sometimes more than one killer page is needed for a discussion. That’s fine, but don’t go for more than 3 or 4, that could feel like overkill to your audience. Especially since conversations around killer pages tend to be quite intense.
