Quality Control Circles

Logo for a movement to improve productivity in companies

National Productivity Board

A bird's eye view of three people in a discussion around a table was abstracted to created this logo symbolising productivity improvement efforts made by workers through Quality Control Circles (QCCs) and Work Improvement Teams (WITs). The blue represents shop floor workers while the three round circles represent three people in discussion.

The logo was designed by Ang Leng Chor, a former professional graphic artist turned product manager. It was the winner out of 400 entries submitted to this contest organised by the National Productivity Board. For his efforts, Ang won $1,000 cash and a plaque.
