Talk:Mean down time

From Wikipedia, the free encyclopedia

I believe that MTTR (Mean Time To Repair) does include any and all time regardless of the reason including troubleshooting time, and the time spent otherwise waiting for a component to be brought back to a working state. This is contrary to the statement made in the article. --24.183.216.14 04:47, 26 December 2006 (UTC)

Hmmmm, thanks for your comment. If this is the case, what is the difference between MDT and MTTR? Also, the R in MTTR can stand for many words, it's not well defined (see MTTR article). If you have a source for saying MTTR includes all down time involved, please, make the appropriate edit. Flippin42
