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.
