Car parts supplier Repco has put prominent projects on hold while its new managing director, Graeme Yeomans, right, reviews operations.

The decision to halt a software project, along with preliminary plans for a new system to manage point-of-sale and warehousing, originally scheduled for release next year, is a response to the company's diminished earnings. Net profit slumped 15.7 per cent to $20.8 million for the year ended June 30, prompting a restructure of the business.
