although he does not know why
c) After reporting the Incident to the Service Desk, the user works on alternative
tasks while the problem is identified and resolved
d) A device works intermittently, thus allowing the user to continue working at
degraded levels of performance while the technician resolves the problem

参考4.4.5.6 Workarounds
In some cases it may be possible to find a workaround to the incidents caused by
the problem – a temporary way of overcoming the difficulties. For example, a
manual amendment may be made to an input file to allow a program to complete
its run successfully and allow a billing process to complete satisfactorily, but it is
important that work on a permanent resolution continues where this is justified –
in this example the reason for the file becoming corrupted in the first place must
be found and corrected to prevent this happening again.
In cases where a workaround is found, it is therefore important that the problem
record remains open, and details of the workaround are always documented
within the Problem Record.
