-During software projects, it is necessary to collect, store and analyze data to support decision making at project and organizational levels. Software measurement is a key practice to process quality improvement and project management. Given the nature of measurement activities, supporting tools are essential. Different tools can be combined to support the measurement process and provide the necessary information for decision making. However, usually these tools are developed by different developers, at different points in time and without concern for integration. As a result, organizations have to deal with integration issues to allow tools communication and properly support the measurement process. This paper presents a study investigating in the literature initiatives involving tools integration to support software measurement. As a result, twelve proposals were analyzed and their characteristics are presented.
