Using the Concept for Decisions
Using the heads to represent different thoughts is an excellent way to present the choices during decision making. Using the same heads implies an inner conflict. Using different heads, e.g., older man and younger man, can imply tradition vs. innovation or discussion between colleagues/team members. Male and female heads can illustrate gender-biased positions. There are many nonverbal signals that the heads can imply.
The example was developed in PowerPoint 2007. Notice the drop shadows and the shadowed text? The decision heads can also be formatted and used well in pre-PowerPoint 2007 versions.
Customizing Concept for Decisions
If you want to change the size/shape of the heads, be sure to group it and resize the entire group. Once resized, ungroup to proceed with other customizations.
Choose colors from your palette that will create a good blended color when the transparency is applied. Some colors when they are blended by overlapping the two semitransparent heads are muddy or unattractive. Try a few combinations until you get a good blended color. Apply a fairly high degree of transparency to it. The transparency is what creates the center overlap "field," where the question or issues is placed.
Don't use 3D with the heads. 3D interferes with the "blending" and makes the two heads look like they are layered – not at all what you want to convey.
Similar to 3D effects, don't use shadows unless you can use the drop shadows in PowerPoint 2007.
Gradients, patterns, and pictures
Gradients work well with these frameworks and add volume to the heads. Make sure that the gradient is not too drastic, as you want the overlaying text to be clearly readable. The series example shows a slight gradient for each the heads. Very subtle, but effective.
Animate the heads as reveals with the text or animate just the text as reveals. Download the animation example for a possible scheme.
