Internal Summary
An internal summary is a brief recap placed within a presentation — not at the end, but midway through — to reinforce key points before moving to a new section. It helps the audience consolidate what they have heard so far and signals a transition to the next topic. Internal summaries are especially valuable in long or complex presentations, where listeners may lose track of earlier content. They improve information retention and help maintain a clear narrative thread throughout the talk.

Display duration
Display duration in PowerPoint refers to the length of time a slide remains visible before automatically advancing to the next one. Setting a display duration enables auto-play presentations that run without manual input — useful for kiosks, event loops, or self-running demos. Duration settings are configured per slide in the Transitions panel and can be combined with timing controls on individual animations to choreograph a fully automated presentation sequence.

It is typically used in early stages of a project — before a full proposal is developed — to test reactions, align stakeholders, or secure initial approval. A good concept presentation clearly communicates the core idea, explains the problem it solves, and outlines the key assumptions, without yet committing to a full implementation plan.
