The blue checkmark is a program that EDS introduced to motivate and recognize their sales force. In the old days before direct deposit, sales commisions were printed on blue checks and the blue color became synonymous with a succesful period.
In order to bring back the excitement of the blue check, these fun checkmarks were created. Everytime a salesperson qualified for a bonus check, they were also awarded an acrylic check.
The program was very well received. At the end of the year, the sales reps are able to turn in their checkmarks for additional prizes.
