Abstract
In these days, most organizations have realised, at last, so important as their software is their data, because it can be considered as an important asset present in° all business organizational processes. Our aim is to optimise the Data Management Process (DMP) in order to assure data quality. For this, we have just drawn a framework based on maturity levels -as CMMI's ones- with specific and generic data quality goals, which are achieved by executing the corresponding activities.
