“…Testing methods in conjunction with industry partners facilitates identification of issues that might otherwise not have been considered and helps in understanding the practicalities of using a method. Karlsson et al [69] identified practical issues around scaling up pair-wise evaluation of requirements to meet the needs of an industrial project, while the analysts testing Sommerville et al's PREview method [26] liked its flexibility and were content to use the aspects of the method that suited their purposes, disregarding some features entirely. Similarly, incorporating regular feedback from analysts into VBRE method development provided an understanding of how the method would be used in practice from early in the study.…”

'Socio-political' issues, such as emotions, values and people's feelings, are often cited as problems in the RE process. A method is described for analysing such issues. The method consists of a taxonomy of stakeholders' values, motivations and emotions (VME), with process guidance for eliciting and analysing these issues for the RE process and design implications. Values are personal attitudes or long-term beliefs which may influence stakeholder functional and non-functional requirements. Motivations are psychological constructs related to personality traits which may be viewed as stakeholders' long-term goals in RE. Emotions are cues to stakeholders' reactions arising from value/motivation conflicts. The method is supported by a website which illustrates the taxonomy with explanations and scenarios describing problems arising from value conflicts, and from poor understanding of stakeholder values. Two method validation studies were undertaken: first, an evaluation of the website and method by novices and RE experts; and second, case study applications of RE value analysis in real-world industrial practice. The method was used by all practitioners, although in different ways, some used it to create an agenda of issues for analysis while others employed the VMEs to interpret stakeholders' views and manage stakeholder negotiations. The validation studies provide evidence for the acceptability of the method for industrial practitioners, illustrating how valuerelated problems are identified and analysed effectively by the method. The utility of analysing VMEs is compared to other 'socio-political issues'-oriented methods in RE and methods which focus on monetized values in product requirements.

Abstract:This chapter provides an overview of techniques for prioritization of requirements for software products. Prioritization is a crucial step towards making good decisions regarding product planning for single and multiple releases. Various aspects of functionality are considered, such as importance, risk, cost, etc. Prioritization decisions are made by stakeholders, including users, managers, developers, or their representatives. Methods are given how to combine individual prioritizations based on overall objectives and constraints. A range of different techniques and aspects are applied to an example to illustrate their use. Finally, limitations and shortcomings of current methods are pointed out, and open research questions in the area of requirements prioritization are discussed.

“…Karlsson et al (1997) were the first in proposing a list of interaction types. Later, Carlshamre et al (2001) propose a set of interaction types as result of an in-depth study of interactions in distinct sets of requirements coming from different software development projects.…”

The selection of a set of requirements between all the requirements previously defined by customers is an important process, repeated at the beginning of each development step when an incremental or agile software development approach is adopted. The set of selected requirements will be developed during the actual iteration. This selection problem can be reformulated as a search problem, allowing its treatment with metaheuristic optimization techniques. This paper studies how to apply Ant Colony Optimization algorithms to select requirements. First, we describe this problem formally extending an earlier version of the problem, and introduce a method based on Ant Colony System to find a variety of efficient solutions. The performance achieved by the Ant Colony System is compared with that of Greedy Randomized Adaptive Search Procedure and Non-dominated Sorting Genetic Algorithm, by means of computational experiments carried out on two instances of the problem constructed from data provided by the experts.
