PurposeThe purpose of this paper is twofold: to incorporate the symbolic relationships among the attributes of customer requirements (CRs) and engineering characteristics (ECs) as well as to factor in the values numerically to enhance the prioritization process for an improved, comprehensive quality function deployment (QFD) analysis. The aim is to develop the concept of assimilating and factoring in the often-ignored interrelationships among CRs and ECs utilizing the weighted average method for the CR and EC correlations with overall calculations.Design/methodology/approachAfter a brief literature review of the methods utilized, the research paper discusses the framework for the correlation triangle challenge and introduces a novel mathematical solution utilizing triangle values in conjunction with computed initial raw weights for CRs and initial priority scores for ECs. The capability and applicability of the proposed model are demonstrated with a real-life example.FindingsThrough the proposed technique, the roof and the interrelationship triangle's signs and symbols are translated into numerical values for each permutation of ECs and CRs, and then the prioritization values are processed and finalized. The proposed model successfully modifies and removes vagueness from an otherwise overlooked part of the QFD process.Practical implicationsThe illustrated case study aptly proves that the proposed methodology yields more revealing and informative outcomes for engineers and designers, thus adding much-needed reliability to the outcome and its analysis. The validation conducted through the rank comparison endorses the premise, and the results obtained reflect the strength and accuracy of the progressive QFD as a product planning tool.Originality/valueThe research article proposes a fresh and unique QFD approach that solves typical procedural complications encountered in a regular QFD. Whereas the traditional methods neglect the interrelationships among CRs and ECs, this new methodology employs them in an improved, numerical way by incorporating them in quantitative analysis, which leads to judicious and improved decision-making.

PurposeThis study aims to integrate the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method with quality function deployment (QFD) which helps to improve the weight of technical attributes by calculating the closeness of particular attributes with the best attributes and farthest from the worst technical attributes simultaneously.Design/methodology/approachFor the fulfilment of the aim of the study, detailed literature is reviewed and a suitable tool for score calculation has been selected. Further, the proposed methodology is applied in a literature-based case study, and a new weight is calculated and compared with the previous weight.FindingsThe finding of the study suggests that higher weightage is assigned to those technical attributes which is very close to the best technical attribute, and lower weightage is assigned to the technical attributes which are very close to worst technical attributes. Therefore, the weight calculated with the help of the proposed methodology will suggest to optimally invest the resources on technical attributes so that the maximum customer satisfaction is achieved.Practical implicationsThe proposed method will help in better score calculation of QFD. Therefore, the use of the proposed method will help in better product and service design for maximum customer satisfaction.Social implicationsProposed methodology aims to help managers, administrators, QFD practitioners and product/service designers to design a new product/service or mange the quality of existing product/services in an effective way.Originality/valueThis is the first kind of study, in which modification in score calculation has been proposed. This modification will help in the better assignment of resources for maximum customer satisfaction.

Purpose This paper is one of seven in this volume that aims to elaborate different approaches to quality improvement in education. It delineates a methodology called Lean for Education. Design/methodology/approach The paper presents the origins, theoretical foundations, core concepts and a case study demonstrating an application in US education, specifically dealing with the problem of improving technology supports and services for instructional purposes in a school district system. Findings An approach borrowed from manufacturing, Lean is aimed at creating and delivering the greatest value to the clients or “customers” in education systems while consuming the fewest resources and eliminating waste. Simultaneously, the method engages the organization in continuous problem solving, learning and making quality improvements with Plan-Do-Check-Act cycles. The core concepts that organize the Lean for Education approach are: continuous improvement and respect for people (Emiliani, 2005). Originality/value Few theoretical treatments and demonstration cases are currently available on commonly used models of quality improvement in other fields that might have potential value in improving education systems internationally, such as large grade kindergarten-to-12 education systems in the USA. This paper fills this gap by elucidating one promising approach. The paper also derives value as it permits a comparison of the Lean for Education method with other quality improvement approaches treated in this volume.

Sustainability Concept

Increasing awareness of the importance of services has given rise to the concept of product-service system where goods and services are sold as an integrated package to customers. On the other hand, the emerging sustainability concept has escalated the demand for sustainability for industries. Consequently, it is necessary to build strategies that lead the company to achieve sustainability goals while keeping competitiveness. Drawing on the necessity service and sustainability concept in the quality improvement of the product-service system, this study aims to develop a systematic design tool by filling the gap to the previous studies. We used Quality Function Deployment (QFD) approach by considering customer requirements (VoC) and stakeholder requirements (VoSt), instead of VoC only, based on the service and sustainability dimensions. We refer to the proposed QFD approach as QFDSPS. We introduce service productivity index (SPI) to measure the performance of the system. Thus, in the proposed methodology, the strategies for quality improvement were defined as subject to VoC, VoSt, and SPI. The methodology was implemented in a Javanese restaurant which meets the characteristics of a product-service system. The result shows that the proposed method can be implemented. The implications due to the implementation of the method are also discussed.
