RE: What sort of control chart do I need for this?

[SOPKrules@aol.com]

Start with the X, MR charts but be careful that you sort by completion date not date of initiation.  Sorting by initiation date will give a strange tailing off of the cycle times - preserve the time order of completion.  If you are able to sort by performer that would also be helpful to do an X,MR for each performer to compare.
