- Quality requirements play a critical role in driving architectural design and are an important issue in software development. Therefore, quality requirements need to be considered, specified, and quantified early during system analysis and not later in the development phase in an ad-hoc fashion. This paper presents the quality performance model that estimates quality targets in relation to market expectations as a basis for the architecting of quality requirements. The purpose of the model is to provide concepts for qualitative reasoning of quality levels in the decision-making of setting actual targets of quality requirements for coming releases of the product. The quality performance model is evaluated at one case company, using a market-driven development approach, in the electronic payment-processing domain. The results show that the model is useful for supporting early decisionmaking in, e.g., release planning of quality requirements

- In software projects involving large and of- ten distributed teams, requirements evolve through the collaboration of many stakeholders, supported by online tools such as mailing lists, bug tracking systems, or online discussion forums. In this collaboration, requirements typically evolve from initial ideas, through clarification, to the implementation of a stable requirement. Deviations from this expected course might in- dicate requirements that are poorly understood, need further negotiation, or better alignment with project goals. If not addressed timely, such problems can surface late in the development cycle with negative consequences such as rework, missed schedules, or overrun budget. This paper presents an approach that provides project managers’ with timely awareness of such requirements-related risks, based on automatic analysis of stakeholders’ online requirements communication. We describe a clarification classifier that automatically analyzes requirements communication in a project and detects clarification events, a catalogue of clarification patterns, and a pattern matcher that suggests communication patterns based on our pattern catalogue. Our approach has been empirically constructed and evaluated in a case study in the IBM Rational Team Concert (RTC) project. We discuss the applicability of our approach in other projects as well as avenues for extending our pattern catalogue towards a theory of clarification patterns.

- The continuous stream of requirements changes that often takes place during software development and can create major problems in the development process. This paper defines a concept we call semantic coupling that can be used during all the phases of a system specification and design to reduce the impact of changing requirements. Within the general framework of the intent specifications, traceability matrices representing the mappings between different abstraction levels are used to evaluate the sensitivity of a given design to requirement changes. The practicality of using the approach on real software is demonstrated using the specification of the control software for a NASA robot designed to service the heat-resistant tiles on the Space Shuttle.

Uni-REPM : Validated and Improved

- Software products are usually developed for either a specific customer (bespoke) or a broader market (market-driven). Due to their characteristic, bespoke and market-driven development face different challenges, especially concerning requirements engineering. Many challenges are caused by an inadequate requirements engineering process, and hence there is a need for process improvement frameworks based on empirical research and industry needs. In a previous article we introduced Uni-REPM, a lightweight requirements engineering process assessment framework based on a review of empirically motivated practices in market-driven and bespoke requirements engineering literature. In this article, we validate this framework in academia as well as industry, in order to prepare Uni-REPM for widespread industry use. We conduct two validations; a static validation based on interviews with seven academic experts and a dynamic validation where Uni-REPM is applied in four industrial organisations. Uni-REPM is refined according to the feedback obtained in the validations. The study shows that Uni-REPM is a quick, simple, and cost-effective solution to assess the maturity level of the requirements engineering process of projects. Moreover, the assessment method using checklists is highly usable and applicable in various international development environments.
