Quality characteristics present several difficulties to be addressed. Negative correlations are one of these issues developers must deal during software development. These correlations mean that supporting a characteristic can negatively impact another one. A well-known solution to help developers identifying such correlations is through non-functional requirements (NFRs) catalogs. Although there are several correlations catalogs proposed in the literature, they do not take into account new characteristics that have arisen with the Ubiquitous Computing (UbiComp) and the Internet of Things (IoT) environment, such as Invisibility. In a previous study, a process for defining a catalog of correlations for quality characteristics was proposed. In this paper, we present partial results of the execution of this process for Invisibility and Usability. We also discuss some challenges regarding catalogs for quality characteristics.
