Assessing quality costs of external failures (warranty claims)

Practical implications of cost of quality: a systematic literature review

Purpose

The present study focuses on the cost of quality (CoQ) based on which organizations can evaluate their quality-related activities in economic terms. The purpose of the study is to identify the CoQ practical implications as well as to group them into logical themes.

Design/methodology/approach

A systematic literature review (SLR) was conducted based on well-known academic publishers, such as Emerald Insight, Elsevier/ScienceDirect, SpringerLink, Taylor & Francis, Wiley and Scopus. Sixty-seven peer-reviewed journal articles in the field of CoQ were collected, which were published between 2010 and 2019. The “affinity diagram” was applied to group the practical implications identified into logical themes.

Findings

A plethora of CoQ practical implications were identified and grouped into the following meaningful themes: benefits of CoQ measurement, effects of CoQ, business sectors measuring CoQ, factors influencing CoQ measurement, CoQ elements, future research in CoQ and the role of government.

Research limitations/implications

The limited number of the publishers and keywords used to search for the articles of interest, as well as the subjectivity of grouping the large number of the practical implications into themes are the main limitations of the present study. These limitations constitute the basis upon which future literature review studies can be designed.

Practical implications

The present study by presenting analytically and in summary (through the themes revealed) the CoQ practical implications, provides all the respective available literature in a single study for the benefit of practitioners and academics. Thus, clear and straightforward guidelines are given to practitioners with regard to CoQ issues and academics with regard to research topics of high interest.

Originality/value

No previous SLR study focusing on analyzing the practical implications of CoQ has been published so far.

A Strategic Approach to Mitigating Operational Failure Across Transitions

It is recognized that projects continue to deliver operational assets that are partially defective. This article proposes this because the causes of operational failures have not been extensively analyzed. This study explores how an infrastructure client made quality a strategic and project delivery necessity by undertaking research to analyze operational failure. A mixed-method approach consisting of three phases was used: (1) to understand the operational failure elements; (2) to explore the causes of operational failure; and (3) to develop a new strategic framework to address failure mitigation. The study showed the need for transferring, applying, and recognizing capabilities across strategic business, project delivery, and operational use transitions.

Cost of quality measurement in food manufacturing companies: the Greek case

Purpose

The purpose of this paper is to focus on the cost of quality (CoQ) of food manufacturing companies. The study aims at empirically validating the conceptual structure of the core dimensions of CoQ (prevention, appraisal, internal and external failure cost) and determining their level and relationships. Determining the reasons for not measuring the CoQ as well as the barriers-difficulties and benefits of the CoQ measurement is also an aim of the present study.

Design/methodology/approach

Greek food manufacturing companies were approached through a structured questionnaire and 91 participated in the study. Exploratory and confirmatory factor analysis, descriptive statistics and correlation analysis are applied for data analysis.

Findings

The structure of the core dimensions of CoQ is empirically validated, while all of them range within medium levels and are inter-related. The reasons for companies not measuring the CoQ as well as the barriers-difficulties of companies measuring the CoQ are not significant. On the contrary, significant benefits are derived from the CoQ measurement.

Research limitations/implications

The small sample of the food manufacturing companies operating in one country and the subjective business evidence collected are the main limitations of the present study.

Practical implications

Food companies can be motivated to establish a robust CoQ measurement system, which would reflect the level of the CoQ dimensions. According to the results of the CoQ measurement, a food company can make decisions to increase the prevention and appraisal costs and decrease the internal- and external-failure costs in order to be more competitive in the market.

Originality/value

The paper provides deeper insights into the level and inter-relations of empirically validated CoQ dimensions. Very few studies on the CoQ in food manufacturing companies have been carried out in Greece and the present study makes the picture of the CoQ status in this sector more clear.

A multidimensional longitudinal meta-analysis of quality costing research

Purpose

The purpose of this paper is to examine the longitudinal evolution of quality costs measurement, depicted in 99 real data studies of the last 30 years. A meta-analysis of these articles is conducted, in order to highlight the evolution of the variables that have been used for the study of quality costing, in relation to the date of publication, business sector and geographical origin of each paper.

Design/methodology/approach

The analysis of the cost components has been conducted with the use of multiple correspondence analysis, which is a useful tool for the exploration of the interrelations among all elements, aiming at the identification of the dominant and most substantial tendencies in their structure.

Findings

The findings suggest that the level of analysis of quality costs is related to the date of publication, the business sector and the origin of each research. Furthermore, it is pointed out that the most prominent prevention costs are related to suppliers’ assurance, internal audit and new product’s design and development. Appraisal costs are mostly defined by quality audits and procurement costs, while failure costs by defect/failure analysis, low quality losses, complaint investigation and concessions and warranty claims.

Originality/value

The present paper is a longitudinal meta-analysis of 99 quality cost papers that have been published in the last 30 years. It explores the evolution of research in quality costing, not only in relation to the cost components in use, but also in terms of date of publication, business sector and geographical origin of the studies.
