Extending the NFR Framework with Measurable Non Functional Requirements
"... Abstract. 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 ..."

cumbersome. Thus, in this paper we apply and extend the NFR Framework to bridge the gap between NFRs and implementation. We have implemented the extended NFR Framework, which we call NFR+ Framework, as a modelling language including a softgoal interdependency graph validation tool with a MetaCase Meta
Enhancing Data Warehouse Quality with the NFR Framework
"... In recent years, Data Warehouse has emerged as a powerful technology for integrating heterogeneous data into a multidimensional repository on behalf of decision-support analysis. The complex extraction, transformation and loading process involved, as well as the aggregational-intensive queries are g ..."

are governed by a multitude of quality factors such as integrity, accessibility, performance, and other domain-specific non-functional requirements (NFRs). This clearly advocates the use of an NFR approach to support high-quality data warehouse specifications. In this work we extend the NFR Framework [3
Enhancing Data Warehouse Design with the NFR Framework

the NFR Framework [3] to define catalogues of major data warehouse NFR types and related operational methods, for latter reuse during the specification stage. We illustrate the contributions of our approach in a case study on a large data warehouse project. 1.
Software Architecture Adaptability: An NFR Approach
- in the Proceedings of International Workshop on Principles of Software Evolution
, 2001
"... Adaptation of software systems is almost an inevitable process, due to the change in customer requirements, needs for faster development of new, or maintenance of existing, software systems, etc. No doubt numerous techniques have been developed to deal with adaptation of software systems. In this pa ..."

level, this paper adapts the NFR (Non-Functional Requirements) Framework and treats software adaptability requirement as a goal to be achieved during development. Through this adaptation, then, consideration of design alternatives, analysis of tradeoffs and rationalization of design decisions are all
A NFR-based Framework for User-Centered Adaptation
"... Abstract. Pervasive environments support users ’ daily routines in an invisible and unobtrusive way. To do so, they include a technical per-vasive infrastructure, which is aware of and adaptive to both the op-erational context and the users at hand. Non-Functional Requirements (NFRs) have been effec ..."

-driven framework for building pervasive systems that maximize fitness with the context and the user. Our contributions are: (i) adaptive task models, a conceptual model to describe user rou-tines that accounts for user preferences over NFRs; and (ii) an adapta-tion framework, which uses our models at runtime
Automated Intrusion Detection Methods Using NFR
- Proceedings of the Workshop on Intrusion Detection and Network Monitoring
, 1999
"... There is often the need to update an installed Intrusion Detection System (IDS) due to new attack methods or upgraded computing environments. Since many current IDSs are constructed by manual encoding of expert security knowledge, changes to IDSs are expensive and require many hours of programming a ..."

and debugging. We describe a data mining framework for adaptively building Intrusion Detection (ID) models specifically for the use of in Network Flight Recorder (NFR) [10]. The central idea is to utilize auditing programs to extract an extensive set of features that describe each network connection or host
An NFR-Based Framework for Aligning Software Architectures with System Architectures Abstract
"... System architectures (SysArch), usually developed during the requirements analysis phase of the information system development process, consider different ways of allocating the system requirements between hardware, software and the network. The requirements pertaining to software are then used to d ..."

Arch may be influenced by the hardware platform in the SysArch. Therefore ensuring alignment between the SoftArch and SysArch could result in an optimal final system. In this paper we use the Propagatory Framework for establishing the alignment between SoftArch and the SysArch. We demonstrate
A UML profile for goal-oriented and use casedriven representation of NFRs and FRs
- In Proceedings of the 3rd International Conference on Software Engineering Research, Management and Applications
, 2005
"... In order for a software system to be of value, it should meet both functional requirements (FRs) and non-functional requirements (NFRs). Concerning FRs, UML has been used as the de facto object-oriented analysis and design notation. Concerning NFRs, the NFR Framework extends, and complements, UML, b ..."

Non-Functional Requirements Framework: A Mathematical Programming Approach
, 2013
"... Non-functional or quality requirements such as, performance, timeliness and security are often crucial for the success of a software system. Several well-known techniques and frameworks have been developed to deal with the functional aspect of requirements engineering. Recent years have seen the eme ..."

the emergence of frameworks that incorporate non-functional requirements (NFRs). The NFR Framework is a qualitative method that bridges the gap between the idea of NFRs, and a software design that encompasses these ideas. The framework functions by modelling NFRs and the associated implementation methods
