Reasoning on Non-Functional Requirements for Integrated Services

2009 17th IEEE International Requirements Engineering Conference, 2009
We focus on non-functional requirements for applications offered by service integrators; i.e., software that delivers service by composing services, independently developed, managed, and evolved by other service providers. In particular, we focus on requirements expressed in a probabilistic manner, such as reliability or performance.

On non-functional requirements: A survey

2012 IEEE Students' Conference on Electrical, Electronics and Computer Science, 2012
In this paper we give the details on Non-Functional Requirements and its importance in various fields. We also investigate the effect of working out for the Non-functional Requirements which leads to the discovery of new Functional Requirements. After the coding phase in the Software Development Life Cycle (SDLC), during the process of articulating the

Non-functional requirements in the design of software

2005
We argue for greater emphasis on design in software engineering courses, and for design under consideration of non-functional requirements. In particular we show that it is sometimes quite easy to determine early whether a design satisfies performance and reliability requirements.

Extending UML with Non-functional Requirements Modelling

2011
Non-Functional Requirements (NFR) have been for too long overlooked during the development of software systems, leading in numerous cases to failure, an over budget or even cancellation of projects. In this paper, we propose a solution to integrate the modelling of NFRs into the UML diagrams.

Focus on Non-Functionals! The Effect of Focussing on Non- Functional Requirements on the Maturity of the Requirements Engineering Process

Communications of the IIMA, 2017
When developing IT systems it is important to know the requirements of the system. Requirements can be classified into different categories. In this study we look at functional and non-functional requirements. Respectively these describe the behaviour of the system (functional requirements) and the criteria under which the system works (the non ...

Tracing Non-Functional Requirements

2011
Non-functional requirements, describing quality concerns such as performance, security, and availability, often exhibit complex interdependencies and trade-offs and have broad-reaching impacts across the architectural design of a software intensive system.

Speech Detection of Stakeholders' Non-Functional Requirements

2006 First International Workshop on Multimedia Requirements Engineering (MERE'06 - RE'06 Workshop), 2006
This paper describes an automatic speech recognition technique for capturing the non-functional requirements spoken by stakeholders at open meetings and interviews during the requirements elicitation process. As statements related to system qualities such as security, performance, and portability are often scattered throughout statements of functional ...

Developing a sustainability non-functional requirements framework

Proceedings of the 3rd International Workshop on Green and Sustainable Software, 2014
Requirements engineers are in a unique position to encourage the consideration of sustainability at a formative phase in the software development life cycle. In this paper, we look at how we can develop sustainability as a non-functional requirement (NFR).

Modelling non-functional requirements of business processes

Information and Software Technology, 2007
This paper presents an approach to the identification and inclusion of 'non-functional' aspects of a business process in modelling for business improvement. The notion of non-functional requirements (NFRs) is borrowed from software engineering, and a method developed in that field for linking NFRs to conceptual models is adapted and applied to business

Automatic clustering of non-functional requirements

2004
Achieving requirement quality is a crucial factor for the quality of the final product. Requirements quality depends also on the way functional and non-functional requirements are organized in the requirement documents. In fact, it is very important to distinguish these two types of requirements in order to guarantee traceability, completeness and lack
