Trustworthiness is an important emerging requirement for software systems deployed by the U. S. Air Force. Trustworthiness, briefly stated, is the ability of a software system to be safe, secure, and reliable under a normal operating environment. However, most software systems have not been developed with trustworthiness in mind. Therefore, how do we systematically identify deficit in trustwort...

Requirements Engineering (RE) is the area of software engineering that deals with the discovery and specification of the objectives for the system under development and the environment in which it is used including the human activities it supports. Requirement Elicitation is process of gathering requirements from stakeholders. Incorporating RE to identify non Functional Requirements (NFR) in ea...

This report explains two methods used for defining Non Functional Requirements (NFRs). Of the two methods one is RELAX which is a requirements engineering language; used to divide requirements into invariant and RELAX-ed. RELAX-ed requirements can be functional or non functional and is an enhanced form of the original requirement. SysML/KAOS has introduced the concept of goals in SysML; infect ...

Problems faced in contemporary practice should be understood to improve requirements engineering processes. System requirements are descriptions of services provided by a system and operational constraints. NonFunctional Requirements (NFR) defines overall qualities/attributes of the system. NFR analysis is a significant activity in this branch of engineering. In this study, a methodology for cl...

Accurate and correctly specified requirements are extremely important in ensuring the production of feasible software products. To assure that the requirements have actually been implemented, there has to be a trace link from requirements to implementation. Thus far requirement engineering has been a rather separate task from software design and implementation from the process point of view. Th...

The non-functional requirements (NFRs) of software systems are well known to add a degree of uncertainty to process of estimating the cost of any project. This paper contributes to the achievement of more precise project size measurement through incorporating NFRs into the functional size quantification process. We report on an initial solution proposed to deal with the problem of quantitativel...

BACKGROUND Interruption in chest compressions during cardiopulmonary resuscitation can be characterized as no flow ratio (NFR) and the importance of minimizing these pauses in chest compression has been highlighted recently. Further, documentation of resuscitation performance has been reported to be insufficient and there is a lack of identification of important issues where future efforts migh...

As in many other software engineering activities, Non-Functional Requirements (NFR) are fundamental in the process of selection of the architectural style and the technologies for developing a software system. To know more about this issue, we are currently driving a survey to find out which architectural styles and technologies are being in use in IT companies and organizations, and their rela...

This paper presents the NFR-Assistant, a prototype CASE tool, which assists the software developer in systematically achieving quality requirements. The tool allows for explicit representation of non-functional requirements, consideration of design alternatives, analysis of design trade-offs, rationalization of a design choice and evaluation of the level of achievement of NFRs. As one of the fi...
