Training for me means a couple of things: it means competence and it means engagement.
Competence in some jobs is clearly more critical than in others. To take it to extremes, from an airline pilot and a surgeon we would expect nothing less than the highest level of competence. From a footballer we would hope for competence and skill (especially if they were part of our team!). However, no-one is likely to die if they have an off day.
There are also different levels of skill and competence. Sometimes a basic level is all that’s needed to perform a task well. At other times a basic level gets someone a start, but the skill and competence has to increase over time if they are to progress.
