Induction, briefing and training

Induction - explaining the values of the organisation, standard terms and conditions of employment.
Briefing - explaining the role that the staff member is expected to undertake based on their existing skills and experience.
Training - providing new skills so that staff can do their job better.

In emergencies induction is often forgotten, briefings are too hasty and training is never given because of a lack of time and opportunity.

Invest in induction and briefing but be realistic about your capacity to train. Instead try to recruit the level of staff you really need, so you don't have to spend too much time on training.
