- Software testing is a necessary part of software development life cycle (SDLC) to achieve a high reliable software system. In today’s software environment of global competition where each company is trying to prove itself better than its competitors, software companies have to continually do up-gradation or add-ons in their software to survive in the market. Each succeeding up-gradation offers some innovative performance or new functionality, distinguishing itself from the past release. We consider the combined effect of bugs encountered during testing of present release and user reported bug from operational phase. The model developed in the paper takes into consideration the testing and the operational phase where fault removal phenomenon follows Kapur-Garg model and Weibull-model respectively. The model developed is validated on real datasets for software which has been released in the market with new features.

Tidskriftsartikel (refereegranskat)abstract
- The first purpose of this study was to verify the relationship between workplace health and quality management, particularly the values ‘leadership commitment’ and ‘participation of everybody’ whose importance previous research has pointed to. The second purpose of the study was to examine the constituents and mechanics of the relationships between health and those values. A case study was carried out in a Swedish manufacturing company using data triangulation in the form of in-depth interviews and focus-group interviews on three levels. The findings show that the perceptions of the quality management values were significantly correlated with the employees’ perception of their health. This finding substantiates earlier studies indicating a relationship between quality and health. Important dimensions of ‘leadership commitment’ and ‘participation of everybody’, regarding health, were identified and described in models. The paper provides additional understanding of the connection between quality management and health, particularly regarding the role of leadership.

- High profitability and customer satisfaction are of supreme importance for any business. To achieve both objectives, an organisation must design a structured approach. To achieve profitability, organisations look to principles of lean manufacturing and techniques such as EFQM, business excellence. This paper reviews such methodologies across different industries, comparing techniques and elements. Its objective is to determine which methodologies are most applicable to the Swedish mining industry and propose a method to achieve lean mining. To this end, the paper looks at the methodologies of a food manufacturing industry, an automobile component manufacturing company, the manufacturing and service sector, and the oil and gas industry. It finds that the method used in the oil and gas industry is more relevant to mining, even though it has some flaws. Further research is needed to adapt this method to the mining industry.

Tidskriftsartikel (refereegranskat)abstract
- The objective of the research is to develop a framework that can be used to gain understanding on the system and might be used to build a System Dynamic model. The results are based on the outcome from stakeholder group model-building sessions, involving stakeholders representing different groups. The sessions were held in connection with a PhD project aimed at developing a System Dynamic model to evaluate the benefits from a quality management system in the construction industry. The main findings are the definition framework of the variables that could be used as a foundation for a System Dynamic model and a suggestion of how the concept of an active quality management system in the construction industry can be defined in a causal loop form. These findings are great value for the construction engineering and management community and an important step towards a formulation of a System Dynamic model.

Tidskriftsartikel (refereegranskat)abstract
- Stakeholder Group Model-Building (GMB) is often used as an approach to form a model in system dynamics (SD) and increasingly also to support strategic decisions in organizations. In this study, grounded theory approach is used to study how 8 participants in GMB experienced the process and to increase understanding of the value of the method. A number of strategies were coded and analyzed and a theoretical model was developed describing: 1) the causal conditions that underlay the development of value adding strategies, 2) phenomena that arose from these causal conditions, 3) the context that influenced strategy development, 4) intervening conditions that influenced strategy development, 5) value adding strategies, and 6) the consequences of these strategies. Subcategories of each component were identified and are illustrated and implications for GMB projects are addressed. A discussion section is presented based on the results and the authors experience of stakeholder GMB workshops.

Managing environmentally driven change in manufacturing organisations : Moving from reactive to proactive behaviour
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Manufacturing companies must become better at managing environmentally driven change in order to establish a sustainable world for future generations. Environmental issues such as energy, natural resources, pollution and waste offer both competitive opportunities and constraints, and are changing the competitive landscape in many industries. Even though several incentives have been initiated such as integrating the environmental management system into the quality management systems, still more needs to be done to achieve sustainable operations. In order to increase understanding of the strategic context of environmentally driven changes this paper explores driving forces for the implementation of environmental improvements within an organisation. Additionally, key factors supporting a successful implementation are further analysed. A framework is proposed which links together lessons learnt from implementing change from change- and quality management into sustainability- and environmental management in order to support manufacturing companies in their decision process towards a better environmental position.

Value modes effect and analysis (ValMEA): a PLS-based theory validation
- 2010
-

Tidskriftsartikel (refereegranskat)abstract
- Value modes effect and analysis (ValMEA) suggests that the concept of customer value can be categorised according to its existence in three different contexts (i.e. production/supply, buying/purchasing, and use) and these three 'modes' of value are interrelated. Based on the collected customer survey data in the house-building construction, two structural models of ValMEA are tested using partial least squares (PLS). The findings from this study confirm previous theory propositions by various researchers. Firstly, these modes of value construct a chain (serial) interconnection, meaning that value in the production/supply context influences the value in the purchasing (buying) context, and the value in the buying context influences the value in use. Individually, value in the production/supply context and purchase value has significant effect on the value in use. Secondly, value in the buying context is a function of core value and added value. Thirdly, value in the buying context can only partially explain the richness of value in use.

Tidskriftsartikel (refereegranskat)abstract
- This paper proposes a new practice of robust design methodology (RDM); to adopt a life cycle approach to noise factor identification. Such practice expands the boundary of traditional use of robust design where noise factors are generally known, observable and experimentally controllable.By exploiting information from claim data of a medium-sized Swedish manufacturing company, several other noise factors were identified and classified into product life cycle stages; factors that are often uncontrollable,unobservable, or unknown. Exploratory data analysis, interviews, and internal documents are used in this study. The results show that by analysing the claims data, the product’s failure modes can be identified and classified into variousproduct life cycle stages. This enables identification of noise factors in each product life cycle stage. The use of a life cycle approach has two major implications. One is to expand the focus of RDM to encompass all product life cycle stages instead of being limited to a product development process. The other implication is that the practice proposed facilitates consideration of more stakeholders, in addition to one single customer by looking at consequences for society at large once the product is in use. Hence, the proposed RDM practice can be supportive of sustainable product development.
