Evaluation of Quality Systems for Specialist Contractors

Quality systems are being adopted by the Swedish building industry to an increasing degree. The present paper examines two categories of specialist contractors — electrical contractors, and plumbing, heating and ventilation contractors — and the introduction of quality systems in these environments. The companies were assessed in terms of the ISO 9001 standard and the Crosby Quality Management Maturity Grid. The evaluation shows that much has been accomplished in efforts to ensure quality, but that much is yet to be done. Considering the investment in resources which the introduction of a quality system represented for these firms, it is noteworthy that none of them measured the effects of quality control in a concrete way. A specific instrument, based on ISO 9001 and the Crosby Grid, is seen as applicable. The importance of developing the evaluation of quality systems further is emphasized, an approach which can be used both by suppliers and by customers.
