Best practice is NOT to do what you did the last time and the times before that.
Best practice is using what you have learned in doing what you now know you SHOULD have done the last time, which – in hindsight – would have given you a better outcome.
The first – and most often used version – is for the lazy ones, and it will ultimately stop being effective.
The latter one is for those who are deeply involved in what they’re doing and are committed towards continuous improvement in everything that they do.
In order to get a better outcome – next time.
