In Figure 1 we grouped the years into three 5 year intervals and have shown the total number of references for TQM and IQM authors for each interval. From 1993-2000 the number of references to TQM authors continued to climb with a steady drop thereafter. The total references to IQM showed a stable trend from 1993 to 2000 with an inclining trend until 2007. A considerable gap exists from 21 references to TQM and 65 references to IQM authors in the 2003-2007 intervals.
