This position paper focuses on contract monitoring for component interfaces, considering the verification of functional and non-functional properties in the contracts. We investigate what properties are needed on behavioral and Quality of Service contracts. We also define what are the requirements on a monitoring environment to handle properly those contracts. We briefly transpose those require...

Initial software quality requirements tend to be imprecise, subjective, idealistic, and context-specific. An extended characterization of the common Softgoal concept is proposed for representing and reasoning about such requirements during the early stages of the requirements engineering process. The types of information often implicitly contained in a Softgoal instance are highlighted to allow...

customer satisfaction is the major concern to many leading companies throughout the world.customer satisfaction is the major concern to many leading companies throughout the world. more firms use satisfaction ratings as an indicator of the performance of products and services and as an indicator of the company’s future. as lately shown companies that are able to identify customer needs and alig...

In this paper, we extend the current approaches to service discovery in a service oriented computing environment, such as Web Services and Grid, by allowing service providers and consumers to express their promises and requirements for quality of service (QoS). More specifically, we allow service providers to advertise their services in an extended DAML-S that supports quality specifications, a...

Many managers and others who are not professional requirements engineers tend to greatly oversimplify requirements engineering (RE). Based on their observations that requirements specifications primarily contain narrative English textual statements of individual requirements and that all members of the engineering team are reasonably literate, there is a common myth that practically anyone with...

The Belief-Desire-Intention (BDI) agent model is a highly favoured agent development model known for its distinct abstraction between components, conceptual adaptability and flexibility in determining its actions. This determination is handled through a plan selection function which determines the most appropriate plan or action given the current state of the environment. Whilst it is conceptua...

This paper aims to develop an Indian-logic based approach for automatic generation of software requirements from a domain-specific ontology. The structure of domain ontology is adapted from Indian logic. The interactive approach proposed in this paper parses the problem statement, and the section of domain ontology, which matches the problem statement, is identified. The software generates ques...

The Joint Steering Committee for Development of RDA has been working on a new standard for resource description and access designed for the digital world: RDA. This standard is scheduled to be released at the end of November 2009. RDA will provide a flexible framework for describing all resources analog and digital, i. e. data that is readily adaptable to new and emerging database structures an...

Requirements engineering faces new challenges due to changes of requirements. 1. We need not only requirements for functionality, but also requirements on the ability of adaptation to environmental needs. 2. For secure, trustworthy software services, we need to analyze the intentions and capability of attackers and potential system abusers. 3. When it comes to offshoring and outsourcing, simple...

As software-intensive systems become more pervasive, more and more safety-critical systems are being developed. In this column, I will use the concept of a quality model to define safety as a quality factor. Thus, safety (like security and survivability) is a kind of defensibility, which is a kind of dependability, which is a kind of quality. Next, I discuss the structure of quality requirement...
