This paper's main objective emphasizes the importance of waterfront design in coastal cities. It reveals that a location is associated with the activities it hosts to become attractive for people or, in other words, to be a destination. In this respect, it proposes students' concept projects for the selected waterfront field study in Istanbul.

This study's conceptual framework is designed according to the qualities compiled from the place-diagram and the power of 10+ (plus) concepts of the PPS (project for public spaces). Accordingly, a fieldwork study based on the qualitative and quantitative research method was conducted as fieldwork in the Istanbul Sarayburnu waterfront, where historical and touristic sight-seeings of the Golden Horn meet with the Bosphorus coastal line. In addition to photo-video recordings, survey questions were also prepared during the field study.

Survey questions inquiries multi questions searching for the place-diagram qualities provide suggestions of 90 people who responded in situ. Results of the case study highlight six alternative proposal projects for the fieldwork prepared based on the power of 10+ concept by the third grade students of the School of Architecture of Istanbul Sabahattin Zaim University (IZU). Based on the survey questions and literature review findings, 10 sub-spatial qualities of waterfronts were disaggregated at the end of the study.

The power of 10+ concept in the study provides a gauge for architects and urban planners; it gives them an excellent tool for assessing the quality of public spaces for placemaking in waterfronts.

Previous studies have generally been based on the PPS's place-diagram qualities with little mention of the interaction with the power of 10+ concept in placemaking. The proposed sub-qualities in the paper's conclusion contribute to architects and urban planners considering a model approach derived from those PPS concepts.

The usage of additive manufacturing (AM) technology in industries has reached up to 50 per cent as prototype or end-product. However, for AM products to be directly used as final products, AM product should be produced through advanced quality control process, which has a capability to be able to prove and reach their desire repeatability, reproducibility, reliability and preciseness. Therefore, there is a need to review quality-related research in terms of AM technology and guide AM industry in the future direction of AM development.

This paper overviews research progress regarding the QC in AM technology. The focus of the study is on manufacturing quality issues and needs that are to be developed and optimized, and further suggests ideas and directions toward the quality improvement for future AM technology. This paper is organized as follows. Section 2 starts by conducting a comprehensive review of the literature studies on progress of quality control, issues and challenges regarding quality improvement in seven different AM techniques. Next, Section 3 provides classification of the research findings, and lastly, Section 4 discusses the challenges and future trends.

This paper presents a review on quality control in seven different techniques in AM technology and provides detailed discussions in each quality process stage. Most of the AM techniques have a trend using in-situ sensors and cameras to acquire process data for real-time monitoring and quality analysis. Procedures such as extrusion-based processes (EBP) have further advanced in data analytics and predictive algorithms-based research regarding mechanical properties and optimal printing parameters. Moreover, compared to others, the material jetting progresses technique has advanced in a system integrated with closed-feedback loop, machine vision and image processing to minimize quality issues during printing process.

This paper is limited to reviewing of only seven techniques of AM technology, which includes photopolymer vat processes, material jetting processes, binder jetting processes, extrusion-based processes, powder bed fusion processes, directed energy deposition processes and sheet lamination processes. This paper would impact on the improvement of quality control in AM industries such as industrial, automotive, medical, aerospace and military production.

Additive manufacturing technology, in terms of quality control has yet to be reviewed.

This study aims to empirically examine whether heterogeneity in personal customer profiles translates to heterogeneity in the valued operational e‐service design attributes. It focuses on a key operational e‐service design attribute – service quality – by investigating whether customers with different profiles (demographics, pattern of use of the service, and pattern of channel use) attach different levels of importance to different dimensions of web site quality.

The study is based on path analysis of data collected from multiple sources in a commercial e‐service setting (e‐banking): data from an online survey of the customers of the e‐service; data stored in the transaction and log files generated by the operation of the e‐service over time; and data from the e‐service provider's customer database and back office IT systems.

The results suggest that: customer demographics, pattern of service use, and pattern of channel use have no influence on the importance attached by customers to web site quality dimensions; and customer demographics affect the pattern of use of an e‐service.

Future research should examine this question in other types of e‐services and should examine other types of profile variables.

Service providers may not need to employ customization at the level of web site quality dimensions. The findings support the existence of the concept of an “optimal” web site design for quality.

The paper answers calls for an increased understanding of the design of high quality e‐services and for multidisciplinary research in the field of services management, in particular, incorporating operations management perspectives.

This paper aims to investigate the phases of new product development within the design-driven innovation (DDI) process, the role of designers and collaborators in the process and how this process relates to some quality principles.

This study adopted a qualitative approach using Gioia methodology. In particular, four Italian manufacturing companies in the home appliances and furniture industry were selected, and data mainly collected through direct interviews were analysed through content analysis.

The new product development related to DDI includes the following phases: the company brief, the designer research, the concept of the designer, the design, legal protection, prototyping, production and the market launch. Designers play a strategic role in the above phases of DDI, but other actors also cooperate and some quality principles affect positively on the process. This study proposes a model for a DDI process in the home appliances and furniture sector.

Although this exploratory study was conducted on only four companies, it advances the DDI research in relation to new product development.

This study makes recommendations to entrepreneurs and managers on how to innovate successfully and to effectively manage designers and collaborators to ensure competition.

This analysis highlights that design-based innovation contributes to improving the quality of life of consumers.

To the best of the authors' knowledge, this is the first qualitative study to examine the phases of new product development in DDI process, the actors involved and relationship to quality principles for the Italian home appliances and furniture sector.

The purpose of this paper is to describe the historical approach to concurrent engineering (CE) which has resulted in product line management (PLM) and then evaluates the theoretical models that have been proposed for design for Six Sigma (DFSS) in order to determine which model is able to provide the most consistent approach with historical development of PLM.

The approach begins with an overview of the approach taken by the Union of Japanese Scientists and Engineers (JUSE) in the development of a coherent quality methodology for structured analysis and problem solving – the Deming Wheel of plan‐do‐check‐act (PDCA) which has become the standard model in Japanese total quality management to define a logical decomposition in process management. In Japan, PDCA is the single logical model which has been broadly accepted as the construct for understanding how to develop both strategic and operational quality methods. The second step in the approach is to examine a similar American development of the model for statistical problem solving that is applied in the Six Sigma method for statistical problem solving: define‐measure‐analyze‐improve‐control (DMAIC). Next, the paper examines the historical sequence in the way the product development process has developed over the past forty years, with emphasis on its military origins (especially CE) and which resulted in the generic model for PLM. The final part of this paper examines the models that have been proposed to implement DFSS over the past ten years and evaluate their logical congruence with the engineering community's design process.

Problems in alignment with the engineering design process were identified with all of the DFSS models and with the non‐structured or “heuristic” approach to developing a coherent body of knowledge related to DFSS.

This paper provides a challenge to the quality community as well as to the academic community. The paper points out the need for rigorous examination of logical models that are proposed for guiding the thinking of practitioners in the use of quality methods for both the engineering of products and business systems. An expose of lack of rationality in the way an approach to DFSS has been investigated calls for more responsibility in the management of the development of this body of knowledge.

It has not been enough to include “quality dimensions” into a product or a service and expect the outcome to be world‐class. Total value signifies a set of multidimensional measures towards realizing a competitive product (goods or services) that the customers would like and are willing to pay a premium price for. A “quality dimensions” set is one of its (total value) multidimensional measures. Such multidimensional value considerations would be vital for a company in maintaining a competitive edge in today’s global and rapidly changing marketplace. The first question is why a “quality dimensions” set has not been enough? The second question is what are those multidimensional sets of measures that make‐up this total value content? The last question is how to determine a cumulative total value‐index that accounts for these sets of measures so that an organization could use this total value‐index to optimize its product realization process and thereby control its (an organization’s) degree of competitiveness. The paper attempts to answer these questions.

In 2000, the Hong Kong Government commissioned the Construction Industry Review Committee (CIRC) to provide a thorough review of the strengths/weaknesses of the Hong Kong construction industry and to recommend improvement measures. The CIRC’s report, released in 2001, recommended many improvement measures related to total quality management (TQM) principles. Despite many of these improvement recommendations being fulfilled in the ten years following the release of the report, there is a lack of literature documenting these achievements and the corresponding level of TQM application. The purpose of this paper is to investigate the extent of TQM application by engineering consultants in Hong Kong using a questionnaire survey.

A literature review was conducted and a survey questionnaire was then designed for a full-scale survey. The data collected from the survey were analyzed using the Statistical Package for Social Sciences. Correlations between the respondents’ scores on the survey questions were established.

The survey findings indicate a moderately high level of application of TQM principles, reflecting a moderately high achievement in implementing the CIRC’s intended improvements. The survey findings further suggest that as a short-term need, focussing on top management leadership and supplier management is necessary for current and scheduled projects, and that organizational learning and people management are the two other major TQM principles that engineering consultants should focus on to sustain their long-term business.

The Hong Kong experience should be of interest to other countries, both regionally and globally, in search of an improvement framework to enhance their quality culture.

This paper is an original contribution. The content of the paper is unique. No one has done this before.

The purpose of this paper is to develop a method to benchmark the service quality of any public facility based on users’ perception, by taking the case of “bus design”. While some researchers have defined level of service (LOS) for highways, transit system and pedestrian facility to measure their service quality, limited attempt has been made to measure users’ perception of service quality for other public facilities which cannot be described by quantitative service levels.

In this research, an average weighted scoring technique has been integrated with the method of successive interval scaling to develop a five graded LOS scale that benchmarks users’ perception of service quality for “bus design”. The method has been exemplified by taking five types of buses currently operating in Kolkata that represent five types of “bus design”. This method can be applied for other public facilities.

By applying the method an LOS scale from LOS A to LOS E was developed for “bus design” in Kolkata that represent users’ perception from “very good” to “very poor”. “Bus design” has been described by a list of attributes identified in this research. “Degree of criticality” of different design attributes based on users’ requirements was used to identify the key attributes for improvement which was also found to vary for different bus user groups in Kolkata.

This research is the first ever attempt to benchmark service quality of a qualitative facility like “bus design” based on users’ perception instead of expert opinion as used by previous researchers.

Architecture influences people and the environment from the past, present and the future. Nevertheless architecture and design quality is viewed as subjective, and benchmarks to achieve consensus are necessary for design or evaluation of buildings. This paper establishes architectural design criteria for design quality of multi-storey housing buildings. A set of the criteria was established with literature review, an operational definition and survey on qualified persons or architects in the professional practice of architecture. The literature reviews identified seven concepts for architecture and design quality, and the operational definition translated this architectural design quality to measurable and observable cases and variables. The survey collected these variable data from a purposive sample of 95 respondents, and these data were examined by statistical analysis. The results of the descriptive statistics, inferential t-tests (p ≤ 0.05) and positive hypothesis testing verified that respondents in general agreed to these seven design concepts as architectural design criteria for design quality. These results established the first ever set of seven architectural design criteria which were ranked in descending order of significance as function, socio-culture, site context, cost, aesthetic of art, sustainability, and Feng Shui. These architectural design criteria can be applied to the design or evaluation of multi-storey housing buildings for the good of people and the environment.

Combined offerings of products and services, that is, a product‐service system (PSS), have been attracting much attention. Consequently, a good design methodology of services as well as that of manufacturing products is needed. The purpose of this paper, is to propose a method for estimating customer satisfaction that enables designers to compare design solutions in the conceptual stage.

In the proposed method, first, the models that represent PSS features with relation to a customer's state is adopted. Then, the authors propose the estimation procedure that utilises a non‐linear value function called the satisfaction‐attribute (S‐A) function to quantify customer satisfaction.

The proposed method centres on the estimation of customer satisfaction. It enables the designers to evaluate design candidates in the conceptual stage where little information is available, and therefore supports iterative improvements without the designer needing to hesitate under the weight of market analysis.

In this paper, the estimation is limited to a single transaction with a customer, rather than cumulative satisfaction that represents a customer's imprints about the provider accumulated by repeating purchases. In future, therefore, the authors need to integrate the concept of effects over time such as loyalty and defection into the proposed framework.

In the application, the proposed method is statistically proven to effectively illustrate customer satisfaction.

This paper proposes the estimation method of customer satisfaction for PSS design. The proposed method allows designers to choose a design solution from the customer viewpoints.
