DR and BCP seem to be handballed completely across to IT these days, I am trying to comprehend why this is.
1.We are the most aware and competent to handle it, as we manage the enterprise's most valuable asset: its systems.

2. We already have SLAs and plans to ensure the continuity of services in the short term. We also have longer term plans, that we actually test. That makes us the most focused and experienced in this area.

3. IT is generally the focal point in an organisation as it impacts on, or interacts with, most other areas. That makes it the natural place to start and to co-ordinate from.

4. IT are used to producing internal plans and proposals that are co-ordinated for the business as a whole.

5. We weren't invited to the meeting where it was decided

I can only speak from UK experience, but it is usually IT and Site Services (the guys responsible for the physical infrastructure) who are the most heavily involved.

The point from my previous post is that, In a disaster (eg. a Flood).
All the information stored in your offices on paper, on peoples desks etc, is lost, How much work would they be doing if the IT systems were up, but all their paper was lost.
In theory it should be business as usual, as stuff that has been filed should already have been entered onto the systems. Stuff that is on the desks may represent uncompleted transactions, but should at least have been booked onto the system as pending action (journalling).

OK you may lose some stuff in the postroom etc. but it will be pretty negligible in the grand scheme of things. Also, if it was a flood there is a good chance you would have sufficient warning to move stuff out of the way, and critical paperwork should be stored in fireproof cabinets outside of business hours.

These days the main reason for storing paperwork is either it is a legal requirement or to keep the external auditors happy (they like to verify things with third party documentation).
