A LEADING quality management consultant says the rush of construction companies winning ISO 9000 quality management certificates ''is just the starting point'' for quality management in the territory, and that interest is rising from other sectors. Mr Robert McCrae, chief executive of McCrae Consultants, added yesterday that he was encouraging firms which had achieved ISO 9000 to move on to other quality programmes. Mr McCrae's company has been running courses in ISO 9000 in partnership with the Hongkong Management Association. ISO 9000 is an international standard setting down rules on how to measure and document quality within an organisation, from the receipt of an order to delivering the product. Over the past few months there has been a flood of construction firms winning ISO 9000, which is awarded after an independent review, after the Housing Authority said from April 1 it would only deal with companies that had achieved this standard. The Housing Authority itself is also seeking registration. ''We're going to see a fairly gradual but steady development of interest from areas other than construction,'' he said. Aerospace, electronics, toy companies and garment makers would be next, he predicted. He also expected the European pattern of rising interest from the service sector to be repeated. It is estimated that 200 companies in Hongkong have achieved ISO 9000, but this would be much lower than the rate in Britain, which has 10 times Hongkong's population and about 100 times as many ISO 9000 companies. ''I think quality assurance in Hongkong is very much a developing scene,'' said Mr McCrae, who added that having operations in China was no barrier to achieving the certificate and that the certificate was not an attempt to impose Western management style on Chinese companies. Interest was rising even from small companies. One company on the course now has just four employees. Some Hongkong companies have complained that ISO 9000 imposes extra paperwork. Mr McCrae said this was a key issue: ''The problem is not really passing the assessment, it's passing the assessment with a system that is effective and efficient. Otherwise you can kill yourself with paperwork.''
