No “black magic” shaman under employ can beat the benefits of information sharing via knowledge base software.
One of our sys admins when asked what he did to fix a technical problem would always say “voodoo”, giving the impression that it was all black magic. This might have raised a laugh, but in actual fact it wasn’t very helpful as he kept the fixes to himself and engineers around him did not learn from him. That engineer is no longer with us, and in the meantime we have adopted Microsoft Sharepoint.
Basically a wiki or information source, Sharepoint is very easy to upload data to and serves as an intranet for small and medium sized businesses. We use it as a knowledge base. Whenever someone comes across a technical problem that is likely to reoccur, the person involved in its resolution creates a page on the wiki. Others can easily navigate to this page and also search for specific subjects. Documents can be uploaded using Windows Explorer or any other file manager, so that the support site has grown very quickly to become a rich store of information tat includes vendor manuals and guides as well as self-generated material.
The same principle can, of course, be extended to any department in the company requiring document storage. The beauty of it is that the storage can be located anywhere and not just at the company’s premises so that it can form part of a company DR plan with very little effort.
