How to Use Harvey Balls in PowerPoint [Harvey Balls Templates Included]
Harvey Balls are small pie charts or ideograms used to visualize qualitative information. Basically, they are small circles filled with color used in comparison tables to rate multiple competitors on certain parameters.
Why Harvey Balls? Quantitative information has always been very easy to visually communicate.

But how do you visualize qualitative information such as “ease of use”, “efficiency”, “safety”, “taste” or “quality”. That’s where harvey balls templates come in.
Who Harvey Balls? To a layman, the first question that comes in mind is “harvey balls who?” Well, harvey balls was invented by a consultant named Harvey Poppel in 1970s. While working with Booz Allen Hamilton consultancy, Harvey Poppel began to draw these for managing internal projects. Their simplicity and ease of understanding soon made it popular among other consultants and very soon, the entire field of consultancy began to employ these little circles. Because of the name of the consultancy firm where they first started being used, they are also known as Booz Balls.

How to Design Harvey Ball Template in PowerPoint:

There are 2 ways to design harvey balls, the first we had shared in our previous blog.
Harvey Balls Design Method #1- Insert Pie Shape
Go to the Insert tab on the PowerPoint ribbon, head over to the Shapes menu and choose the PIE shape. Move any of the two yellow handles to manually adjust the amount of fill you need (see the screenshot below). To complete the harvey balls shape, add a circle of the same size, remove its fill color but retain the outline. This will give you the harvey balls outline and complete your shape.
Harvey Balls Design Method #2- Insert Pie Chart
The second way to design harvey balls is to insert Pie Chart in PowerPoint. Go to the Insert tab, head over to the Charts and select the Pie chart option. By default, a pie chart with four values will open on your screen. Remove two elements to have just two values in your chart. Keep the data 75:25, 50:50 or 25:75 depending on the harvey ball variation you need.
You can change the colors in the chart as per your preferences. Right click on the chart area and click “Format Data Series” to customize fill and outline. For a blank harvey ball, you need not insert a pie chart. Simply insert a circle, remove its fill and adjust the thickness of the outline.
