正确答案：(c) An organisation considering the use of external recruitment consultants would make its decision upon the availability, level and appropriateness of expertise available within the host organisation and its likely effectiveness, together with the cost of using consultants set against the cost of using the organisation’s own staff. The organisation should consider the level of expertise required of potential employees and therefore the appropriate knowledge required of the consultants and the need for impartiality or security which may be of particular importance for some organisations. In addition, the views of internal staff as to the likely effect of using outside consultants must be considered, as is the effect the use of consultants might have on the need to develop expertise within the organisation.
