Your boss asks you to work through the weekend to install new software on the applications server that serves up applications to
20 users. The following Monday, all users report they cannot open their data files. After speaking with technical support for the new application, you discover it is not compatible with the old data files. Which type of documentation should you refer to first to address this problem?
To begin with, the term of back-out plan in the field of computers refers to the situation where a person wants to <u><em>restore a system to its original or previous state</em></u> in the case where there is a failure trying to implent a new system. Moreover, this back-out plan works as an action process where once the failure has happened then the system will <u><em>intiate a series of procedures to uninstall or disintegrate the system that had the failure</em></u>. It basically defines a contingency plan component of the IT service management framework.
Secondly, in the case presented where a person must decide what document he should address to resolve the problem then a back-out plan will be the most common response given the fact that it will quickly uninstall the new software that was not compatible with the old data fields and help the users to open their files without problems and later seek for a new way to install that new software.
