Update Policy

Tuesday update policy …..

Never Mondays, because some big organisations have IT rules that set Mondays aside for clearing up any crises that might have happened over the immediately preceding weekend.

Never Fridays, in case of any crises that might arise in the immediately following weekend as a result.

And never Wednesdays or Thursdays, because Tuesday gives you the longest clear run of spare weekdays before Friday arrives and shuts down the so-called “change window” once again.
