Catalogue of Invisibility As a Non-Functional Requirement and Its Co-Relation With Other Non-Functional Requirements

Abstract

Requirements are vital for fostering a framework. These are normally arranged into four significant classes i.e. Business, Functional. (FRs), Non-Functional. (NFRs) and Domain Requirements. The focal point of our thesis is on non-functional requirements and their correlation with other NFRs. Correlations between NFRs are typically in the form of catalogues which is a collection of information assembled from past experience. There are many studies which present catalogues of these correlations but invisibility being a new NFR of IoT related systems is not included in them. Invisibility is about keeping user focus on the task rather than the tool. Invisibility means “either the merging of.technology in the user environment or.the decrease in the interaction.workload”[6]. Catalogues are the important tools for collecting correlations among the non-functional requirements. These catalogues will help the practitioners to select appropriate strategies to incorporate Invisibility in the system. Invisibility is a new functional requirement that arises from the need to minimize user interaction with the system and make the user interaction easier. There are many types of NFRs and each one requires specialized knowledge. They can be correlated, which shows that adding.one can impact the.achievement of another, positively or negatively. For this particular issue the software practitioners developed a solution which is known as a catalogue. Then, there is a need to know the current NFR catalogs to both support software development and to identify their challenges that these NFRs may present.
