“…QFD for decision-making has been commonly studied in combination with other decision-making models, for example, a decision-making model that combines QFD and fuzzy theory [33][34][35][36][37]; a decision-making model that combines fuzzy-based QFD and the analytic network process (ANP) [38]; and a decision-making model that combines QFD and ANP [39]. Furthermore, the Kano [40], DEA [41], rough set [42], Simple Multiattribute Rating Technique (SMART) [43], conjoint analysis [44], Multiattribute Value (MAV) [45], and Fuzzy Analytic Hierarchy Process (FAHP) [37] models have all been used in QFD for the design of quality assessment methods, where the focus is on relative comparison among the products.…”

This paper investigates the feasibility of quality function deployment, technique for the order of preference by similarity to ideal solution (QFD-TOPSIS) in presenting user preferences for multiple alternatives, such as construction technologies, products, systems, and design solutions, with trade-off technical characteristics (TC). The original QFD as house of quality (HOQ) defines the requirements and features as subjective matrix relations, which cause interpretations to vary across users and limit its industrial applications. QFD-TOPSIS is a new model that combines the benefits of QFD with those of TOPSIS, maintains the subjectivity and objectivity evaluation of the technical characteristics (TC), and rates the preferences by considering users' individual propensity for requirements. In addition, QFD-TOPSIS rates the preferences through the reciprocal compensation effects of trade-off TC and filters unsuitable alternatives with predefined restrictive conditions. Trade-off refers to conflicts and/or contradictions between attributes, often arising in multicriteria decision-making. Users or project stakeholder groups define the priorities of trade-off TC that directly influence product preferences and decision-making. In the present study, we have developed a Web system based on the QFD-TOPSIS logic and tested its operation to verify its industrial applicability and viability for automatic quality evaluation.

How requirements development could support design of effective and resource-efficient offerings

What a company offers its customers has to fulfil several different needs, desires, constraints, which can originate from multiple different sources that affect the offering throughout its life cycle. All these criteria have to come together and be translated into statements that can support the designer's understanding of the offering's purpose. This translation is done through a requirements development process to provide a controlled process to define statements that describe what the offering is supposed to fulfil.This research provides insights on key challenges and success factors in requirements development to support the design of effective and resource-efficient offerings. Namely, it identifies crucial sources and aspects to be considered, and a requirements development process demonstrating how to overcome identified challenges. By getting the requirements right from the beginning, sub-optimisation and unnecessary time and risks can be avoided.The consideration of accurate sources and aspects is considered to be one of the most important factors for the successful design of offerings. It is also in the earliest phases of design, that is to say requirements development, where one has the greatest possibility to affect the environmental impact of the offering. What is missing, however, is sufficient and appropriate support in industry on how to do so. VIII IX APPENDED PAPERSThe following papers were written during the research and set the foundation for this thesis: Contributions in the papers:Paper 1: The author of this thesis solely carried out this review (Systematic Literature Review 1), and the paper was to about 95% written by her. The co-author supported in the research process and supported with background knowledge in the area, framing and scope.Paper 2: This paper was prepared in collaboration between the authors, from idea to submission. Each author contributed with cases as well as knowledge from their own expertise. The author of this thesis contributed specifically with the idea to focus on SMEs, and also added the sustainability aspects of providing integrated offerings. The author of this thesis also contributed with one of the use cases (that originated from Interview Study 1), and wrote about 30% of the text in the paper. Paper 3:The literature review and the company cases were based on results from Systematic Literature Review 2 and Interview Study 1. The author of this thesis wrote the main draft of the manuscript. Co-authors supported the work along its process, and especially with rewriting and reworking when revising the paper after the first submission.

“…In fact, “the unique approach of QFD is its ability to integrate customer demands with the technical aspects of a service” (Andronikidis et al ., 2009). Several authors have been using this approach in various services environments, such as law firms (Esteban-Ferrer and Tricás, 2012), after-sales services (Padkil et al , 2012) or healthcare (Azadi and Saen, 2013).…”

Purpose The purpose of this paper is to discuss the causes for the discrepancy between the utilization of statistical process control (SPC) in services and manufacturing. Furthermore, an approach for integrating customer demands and technical aspects of a service is presented. Services are very often characterized by a large number of characteristics, with relatively few observations. This research addresses a methodology based on Z and W charts, proposing it for the control of service features. An example associated with service provision is presented to illustrate the computation of Z and W as well as its interpretation. Design/methodology/approach The shortcomings of traditional control charts are stated and compared with the control charts for Z and W. An example illustrates how to utilize these charts, their ability to monitor several characteristics simultaneously, along with a continuous monitoring of process capability. Findings The proposed approach allowed the representation of several process characteristics in the same charts, even when those characteristics are not collected with the same periodicity. The Z and W charts are dimensionless and can be applied whenever it is possible to estimate process parameters, being an interesting approach to be utilized in Phase 2 of SPC. The difficulty for identifying the existence of non-random patterns emerges as the major shortcoming for these charts. Research limitations/implications The proposed approach is a contribute to overcoming the discrepancy that persists between the utilization of SPC in services and manufacturing. Nevertheless, service production and consumption are frequently simultaneous, which constitutes an issue hard to deal with that is not fully addressed in this piece of research. Furthermore, the Z charts also present some disadvantages, notably an increased difficulty for analyzing the existence of non-random patterns, which worsens as increases the number of products/quality characteristics to be checked. Practical implications The proposed charts are very flexible and provide a rational utilization of resources. In fact, the representation of several processes is possible, along with the traditional analysis of patterns, thus providing an effective approach for controlling services processes. Social implications Several quantitative approaches that have been utilized in manufacturing for a long time are still scarce in services. However, services play a major role in modern economies, being clear that improvements in service provision might have a direct impact on society. Originality/value The approach was based on the utilization of Z/W with samples, but it can be extended to individual observations or even to the control of discrete variables. Additionally, a methodology for process capability analysis in real-time is also proposed.
