Dont take them personally. 1. Lines © http://www.flickr.com/photos/twinysam/4988273864/ Never use 0pt line width Wrong Right Visible from the far end of the room Have consistent line width Wrong 0.06 0.32 0.10 Right 0.06 0.06 0.32 Maybe two very different widths; not more Use only one line ending Wrong Right People at the far end wont see the difference Use one dashed style Wrong Right Guess Arrows instead of lines vs. When? See example on next slide Use connectors, not straight lines With lines With connectors Shapes instead of lines (sometimes) Phase 1 Phase 2 Phase 3 vs. Phase 1 Phase 2 Phase 3 They look better on simple workflows Colors instead of outlines (sometimes) vs. Useful to reduce the number of colors 2.

Nesting One nesting level per slide Wrong Unique slide One nesting level per slide Right Slide 1 One nesting level per slide Right Slide 2 One nesting level per slide Right Slide 3 One nesting level per slide Right Slide 4? Is this level really needed? But, wont adding slides increase the presentation complexity?Yes, it will.But less than nested shapes. Complexity → → ting Nes Sli d es → 1 slide / 1 nesting level If you need everything in one place You are not making a presentation Consider other formats © http://www.flickr.com/photos/yetti/8743214/ 4.
