Information such as " security " or " user -friendliness " are harder to reproduce at a glance. For Harvey Balls are often used.

They are also widely used for qualitative comparisons in project management to highlight the degree of goal achievement.

The invention is based on Harvey Poppel, who introduced it in the 1970s as an employee of the consulting firm Booz Allen Hamilton. For this reason, Harvey Balls are sometimes referred to as " Booz - Balls".

Harvey Balls have nothing to do with Harvey Ball, inventor of the smileys.
