Software package selection plays a crucial role in the deployment of software systems. One of its main current problems is how to deal with the vast amount of unstructured, incomplete, evolvable and widespread information that highly increases the risks of taking a wrong decision. It could be said that nowadays there are not satisfactory solutions to that problem. In this paper, we propose an approach to systematically tackle these information quality problems by stating a reference model embracing quality indicators that facilitate the collection, storage, retrieval, analysis and reuse of information in a quality assurance environment. We illustrate it with a scenario of use that shows how this reference model may be used to support software package selection decision-making.
