QC Circle Activities

Since 1965, we have been moving forward with problem-solving activities using a small-group structure (QC Circle Activities) as a means of improving the workplace through employees’ ingenuity and mutual education. In 1966, we held our first QC Circle Conference, titled the “First All-NHK Spring QC Effectiveness Case Presentation Conference.” The title was changed in 1978 to the “All-NHK Spring Circle Conference,” and has continued under that title since then. The 46th of these events was held last year (fiscal 2019), with participation by 13 circles including those from domestic and overseas group companies, who presented the details of their day-to-day work improvements.
