When you send a certified letter, the person receiving it has to sign a receipt acknowledging it was delivered and received. The receipt (or a copy) is sent to the person who â¦ mailed it to prove that the letter was delivered and received. This eliminates the excuse I never received it - especially in legal matters.ou do not mark the letter itself Certified, although you may note in the body text that you are mailing the letter Certified. Seal and address your letter as usual. At the Post Office, obtain and fill out a Certified Mail form.

In software engineering, software configuration management (SCM or SWCM) is the task of tracking and controlling changes in the software, part of the larger cross-disciplinary field of configuration management. SCM practices include revision control and the establishment of baselines. If something goes wrong, SCM can determine what was changed and who changed it. If a configuration is working well, SCM can determine how to replicate it across many hosts.
