Re: ‘No lessons learned’
At the end of my career in blue, we (in the Squipper Eng Authority) were told by their ‘airships’ that the phrase ‘lessons learned’ was not to be used in any of our report writing. We were allowed to use the phrase ‘Lessons identified’.
I resisted the temptation to add ‘…..and can be ignored’
hey ho.
