Operation
Cerebus was the German code name for the naval operation, on February 12th
1942, that saw three capital warships: Scharnhorst, Gneisenau, and Prince
Eugen, race through the English Channel in broad daylight.
This
daring coup de main was partially failitated by a cock-up on the British side.
(There were lots of cock-ups that day, this one has educational benefits.) The
British did have a plan in the event of a naval excursion into the English
Channel. In fact it was a very detailed response, and as such it was a secret.
A secret so precious that only copy in Dover, the main port on the Channel
Coast, was kept locked in a safe.
On the
day the plan was needed it just so happened that the officer who had the key to
the safe was on leave in the South West of England, with the key! So the
response to this daring foray was delayed whilst people made up a response on
the spare of the moment. The resulting actions
therefore were poorly coordinated and ultimately unsuccessful.
This
piece of history has implications and warnings for project managers who have
responsibility for disaster recovery plans. Too often these plans are outdated
and nobody knows who has copies and where they are stored. Often the plans are
stored on the very computer they are supposed to recover! An unavailable plan
is the same as no plan!
So it is
essential that you make sure everyone knows where the plans are, that they are
accessible 24/7, and the correct people and their empowered deputies are available:
Disasters don't recognize holidays, Public or otherwise.
Also the
plans must be reviewed and walked through regularly. You don't want debates about
what the plan means when your business is circling the drain. As a colleague of
mine once said, "smoke coming out of a bank's data center is never a good
sign".
