It is a proven fact that when business audits are repeated on a regular cycle, major benefits can be achieved. However "this fixed asset is not practical for small and medium enterprises" I hear you say and I agree.
But you still have responsibilities as directors for the health of your business. You can not be sure that any minor problems are potential indicative of a more serious and major problems lurking in the background and gaining strength. If this is the case then when it finally reveals itself it can be too late for a quick fix but requires major surgery to avert failure.
You should then work with the interim resource for a "as is" definition, to plan for recovery and agree what internal or external resource is to be utilised for the check-up or recovery.
If there is no internal resource available then bring in an external resource for a fixed period at an agreed rate. Clearly define the areas to be captioned and be honest in your own evaluation of any issues to get value for your Money. Sometimes you need to bring in the whole division and sometimes "one solitary scout" will do just fine.
