person.

• Can be kept up to date.

• Available 24/7.

• Lower cost than employing NHS staff,

e.g. in a call centre.

• Allows access to an expert where not

available locally.

decision / gives probabilities so that a

user can decide whether to accept the

decision or not

• Allows employees to learn from the

system
