In 1992, an analysis of the need for clerical workers was made at the Aarhus School of Business. An identification of 'customers' and 'customers' expectation' was made in order to apply these terms in planning a specific vocational education based on apprenticeship training. The data collection was made by means of a mailed questionnaire, with 376 Danish companies participating in the survey. The survey shows a clear profile regarding the qualifications ('customers' whats') clerical workers are expected to have. By means of factor analysis the expected qualifications have been 'collected' as working functions of a clerical worker The survey also indicates which skills companies can teach during an apprenticeship ('customers' how').
