Don't think disasters won't happen to you!
Your organisation is only as good as the people you depend upon to run it. How would you cope if your staff can't get to work?
Your organisation is only as good as the equipment you use or the services you rely on to support it. How would you cope without electricity, or broadband access?
Your data is one of the most valuable things you have in your business. Is yours backed up? Do you have off-site storage and redundant systems? Do you have mirrored servers?
And consider this : it's all very well making sure your own business is prepared, check your key suppliers are too!
You never know what's around the corner. Things conspiring against you to mess up your day. They're outside your control, but the better prepared you are to cope with them, the less the risk of your day to day business operations grinding to a halt.
