Very interesting session.  Like the absencdoor documentation being the number 1 security risk.  Many organisations think not producing documentation saves money.  This potentially is only true in the short term.  Other key considerations are that the documentation needs to be available in a format that others can access and understand.  Secondly the documentation needs to be well maintained. insiders in any of these additional requirements will reduce and ultimately invalidate the benefit of any documentation that is produced.  There are lots of other things that can simplify document production and management.
