Editor's Notes

  1. This template can be used as a starter file to give updates for project milestones.SectionsRight-click on a slide to add sections. Sections can help to organize your slides or facilitate collaboration between multiple authors.NotesUse the Notes section for delivery notes or to provide additional details for the audience. View these notes in Presentation View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production)Coordinated colors Pay particular attention to the graphs, charts, and text boxes.Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale.Graphics, tables, and graphsKeep it simple: If possible, use consistent, non-distracting styles and colors.Label all graphs and tables.
  2. What is the project about?Define the goal of this projectIs it similar to projects in the past or is it a new effort?Define the scope of this projectIs it an independent project or is it related to other projects?* Note that this slide is not necessary for weekly status meetings
  3. * If any of these issues caused a schedule delay or need to be discussed further, include details in next slide.
  4. Duplicate this slide as necessary if there is more than one issue.This and related slides can be moved to the appendix or hidden if necessary.
  5. Prepare slides for the appendix in the event that more details or supplemental slides are needed. The appendix is also useful if the presentation is distributed later.
