GDD's core service is the provision of services and data management systems, to assist in the effective collection, management and analysis of all of your technical data.

The real financial value of effective data management is rarely fully appreciated, as outlined in an article published in the AusIMM bulletin some time ago. Be sure to have a read through our philosophy to see how implementing an effective data management system will save you significant time and money.
