Included in this overview are metaposts and comments that have to do with process improvement. It includes two metaposts on Six Sigma, as well as one each on process mapping, kaizen and cycle time (See my post of Feb. 13, 2008: Six Sigma with 18 references; July 24, 2009: Six Sigma in law departments and the firms they use with 11 references and 1 metapost; April 9, 2009 #2: process maps with 6 references; May 15, 2009: kaizen and continuous improvement with 6 references and one metapost; and March 5, 2008: cycle time with 18 references.).
Other posts have added ideas (See my post of March 23, 2006: poka-yoke or mistake-proofing; April 9, 2009: takt time; and July 14, 2009: Toyota’s A3 technique.).
