Forskningsöversikt (refereegranskat)abstract
- Background: Software quality is complex with over investment, under investment and the interplay between aspects often being overlooked as many researchers aim to advance individual aspects of software quality. Aim: This paper aims to provide a consolidated overview the literature that addresses trade-offs between aspects of software product quality. Method: A systematic literature map is employed to provide an overview of software quality trade-off literature in general. Specific analysis is also done of empirical literature addressing the topic. Results: The results show a wide range of solution proposals being considered. However, there is insufficient empirical evidence to adequately evaluate and compare these proposals. Further a very large vocabulary has been found to describe software quality. Conclusion: Greater empirical research is required to sufficiently evaluate and compare the wide range of solution proposals. This will allow researchers to focus on the proposals showing greater signs of success and better support industrial practitioners.

Towards Collaborative GUI-based Testing
- 2023
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Context:Contemporary software development is a socio-technical activity requiring extensive collaboration among individuals with diverse expertise.Software testing is an integral part of software development that also depends on various expertise.GUI-based testing allows assessing a system’s GUI and its behavior through its graphical user interface.Collaborative practices in software development, like code reviews, not only improve software quality but also promote knowledge exchange within teams.Similar benefits could be extended to other areas of software engineering, such as GUI-based testing.However, collaborative practices for GUI-based testing necessitate a unique approach since general software development practices, perceivably, can not be directly transferred to software testing.Goal:This thesis contributes towards a tool-supported approach enabling collaborative GUI-based testing.Our distinct goals are (1) to identify processes and guidelines to enable collaboration on GUI-based testing artifacts and (2) to operationalize tool support to aid this collaboration.Method:We conducted a systematic literature review identifying code review guidelines for GUI-based testing.Further, we conducted a controlled experiment to assess the efficiency and potential usability issues of Augmented Testing.Results:We provided guidelines for reviewing GUI-based testing artifacts, which aid contributors and reviewers during code reviews.We further provide empirical evidence that Augmented Testing is not only an efficient approach to GUI-based testing but also usable for non-technical users, making it a promising subject for further research in collaborative GUI-based testing.Conclusion:Code review guidelines aid collaboration through discussions, and a suitable testing approach can serve as a platform to operationalize collaboration.Collaborative GUI-based testing has the potential to improve the efficiency and effectiveness of such testing.

Evaluating two Ways of Calculating Priorities in Requirements Hierarchies : an Experiment on Hierarchical Cumulative Voting
- 2009
-
Ingår i: Journal of Systems and Software. - : Wiley Blackwell. - 0164-1212. ; 82:5, s. 836-850
-
Tidskriftsartikel (refereegranskat)abstract
- When developing large-scale software systems, there is often a large amount of requirements present, and they often reside on several hierarchical levels. In most cases, not all stated requirements can be implemented into the product due to different constraints, and the requirements must hence be prioritized. As requirements on different abstraction levels shall not be compared, prioritization techniques that are able to handle multi-level prioritization are needed. Different such techniques exist, but they seem to result in unfair comparisons when a hierarchy is unbalanced. In this paper, an empirical experiment is presented where an approach that compensate for this challenge is evaluated. The results indicate that some form of compensation is preferred, and that the subjects’ preference is not influenced by the amount of information given.

An Evolutionary Perspective on Socio-Technical Congruence:The Rubber Band Effect
- 2013
-
Ingår i: International Symposium on Empirical Software Engineering and Measurement. - Baltimore : IEEE Xplore.
-
Konferensbidrag (refereegranskat)abstract
- Conway’s law assumes a strong association between the system’s architecture and the organization’s communication structure that designs it. In the light of contemporary software development, when many companies rely on geographically distributed teams, which often turn out to be temporarily composed and thus having an often changing communication structure, the importance of Conway’s law and its inspired work grows. In this paper, we examine empirical research related to Conway’s law and its application for cross-site coordination. Based on the results obtained we conjecture that changes in the communication structure alone sooner or later trigger changes in the design structure of the software products to return the sociotechnical system into the state of congruence. This is further used to formulate a concept of a rubber band effect and propose a replication study that goes beyond the original idea of Conway’s law by investigating the evolution of socio-technical congruence over time.

Using the Analytic Hierarchy Process for Evaluating Multi-Agent System Architecture Candidates
- 2006
-
Ingår i: Agent-Oriented Software Engineering VI. ; , s. 205-217
-
Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Although much effort has been spent on suggesting and implementing new architectures of Multi-Agent Systems (MAS), the evaluation and comparison of these has often been done in a rather ad-hoc fashion. We believe that the time has come to start doing this in a more systematic way using established methods. For instance, we argue that it is important to evaluate the architecture candidates for a particular application according to several quality attributes relevant to that application. The architecture that provides the most appropriate balance between these attributes should then be selected. As a case study we investigate the problem of load balancing and overload control of Intelligent Networks and present four MAS architectures that can be used to handle this task. We instantiate each of these and define metrics for the selected quality attributes. The instantiations are studied in simulation experiments and measurements of the metrics are recorded. The measurements are then analyzed using the Analytic Hierarchy Process, which is a basic approach to select the most suitable alternative from a number of alternatives evaluated with respect to several criteria. We illustrate how such analyzes can be used for deciding which architecture candidate is the most appropriate in different situations.

Investigating impact of business risk on requirements selection decisions
- 2009
-
Konferensbidrag (refereegranskat)abstract
- In market-driven software product development, requirements that can potentially go into a product or a product release represent different kinds of investments. Requirements differ in the type of value that they provide and level of risk associated to investing in them. In this paper we investigate how business risk associated with different requirement types is considered by the decision makers and how it affects requirement selection decisions. The results of the conducted case study indicate that due to lacking methods for handling the requirements business risk, requirements with low level of risk are preferred over other type of requirements such as innovations and architectural improvements.

Needs Oriented Framework for Producing Requirements Decision Material : NORM
- 2008
-
Konferensbidrag (refereegranskat)abstract
- The need of understanding and supporting requirements engineering decisions in market-driven product development is motivated by the complexity and economical impact of these decisions. While being a key for success, correct and timely decisions are dependent on the availability and the quality of decision material (requirements, business cases, costvalue estimations etc). This paper presents a needsoriented framework (NORM) for identifying and assuring the creation of appropriate decision material for RE decisions. NORM is based on analysis of the applied RE process and characteristics of separate RE decisions, focusing mainly on pre-project activities. The framework is developed in close cooperation with industry with the intention to ensure that resources are spent on producing just-the-necessary information at the right time and to be able to monitor and control this production effort.
