Abstract
Purpose
Food manufacturing companies which are essential for national economies, need to attach importance to the adoption of both the lean manufacturing (LM) operational excellence methodology and the Industry I4.0 (I4.0) technologies that empower LM to achieve operational improvement. This study aims to focus on the Greek food manufacturing companies and determine the degree of implementation of LM practices and I4.0 technologies and the impact of I4.0 on LM.
Design/methodology/approach
A survey was conducted based on a structured questionnaire which included items reflecting LM practices and I4.0 technologies. A sample of Greek food manufacturing companies were approached and 102 of them fully completed the questionnaire. Descriptive statistics were applied to determine the degree of implementation of LM practices and I4.0 technologies, while the impact of I4.0 on LM was determined through the linear regression analysis.
Findings
The degree of implementation of LM practices in the responding food manufacturing companies is high, while the degree of implementation of I4.0 technologies is low to medium. The findings also support a significant and positive impact of I4.0 on LM.
Research limitations/implications
The small size of the sample of the responding Greek food manufacturing companies, the subjective character of the data collected and the cross-sectional nature of the study, constitute the main limitations of the study. Based on these limitations, further studies can be designed.
Practical implications
The present study findings can guide the managers of the food manufacturing companies to further increase the degree of implementation of LM practices through adopting I4.0 technologies. Therefore, they can improve quality, eliminate waste, survive and be more competitive in the current difficult business environment. Academics can also benefit from the present study, given that it provides the LM practices and I4.0 technologies that can be further tested and validated in the food sector.
Originality/value
To the best of the authors’ knowledge, this is the first study that focuses on LM and I4.0 in the Greek food manufacturing companies operating in a business environment where the crises of finance, energy and the Covid-19 pandemic dominate.

Abstract
Purpose
Lean distributed manufacturing (LDM) is being considered as an enabler of achieving sustainability and resilience in manufacturing and supply chain operations. The purpose of this paper is to enhance the understanding of how LDM characteristics affect the resilience of manufacturing companies by drawing upon the experience of food manufacturing companies operating in the UK.
Design/methodology/approach
The paper develops a conceptual model to analyse the impact of LDM on the operational resilience of food manufacturing companies. A triangulation research methodology (secondary data analysis, field observations and structured interviews) is used in this study. In a first step, LDM enablers and resilience elements are identified from literature. In a second step, empirical evidence is collected from six food sub-sectors aimed at identifying LDM enablers being practised in companies.
Findings
The analysis reveals that LDM enablers can improve the resilience capabilities of manufacturing companies at different stages of resilience action cycle, whereas the application status of different LDM enablers varies in food manufacturing companies. The findings include the development of a conceptual model (based on literature) and a relationship matrix between LDM enablers and resilience elements.
Practical implications
The developed relationship matrix is helpful for food manufacturing companies to assess their resilience capability in terms of LDM characteristics and then formulate action plans to incorporate relevant LDM enablers to enhance operational resilience.
Originality/value
Based on the literature review, no studies exist that investigate the effects of LDM on factory’s resilience, despite many research studies suggesting distributed manufacturing as an enabler of sustainability and resilience.

Abstract
Purpose
The purpose of this paper is to develop an instrument that measures the effectiveness of the ISO 9001 Quality Management System (QMS), based on its components, meaning the ISO 9001 objectives; and to validate this instrument in the food manufacturing sector.
Design/methodology/approach
Bearing in mind the definition of “ISO 9001 effectiveness”, the ISO 9001 objectives and their indicators are identified in the literature. Based on these indicators, a measurement instrument is developed and then empirically validated through collecting preliminary data from 335 Greek food manufacturing small and medium‐sized enterprises (SMEs). After testing the assumptions of multivariate analysis, exploratory factor analysis as well as first and second order confirmatory factor analysis are applied.
Findings
The data collected reveal, as identified in the literature, the three‐dimensional nature of the ISO 9001 objectives (continuous improvement, prevention of nonconformities and customer satisfaction focus). The responding food manufacturing SMEs demonstrate a high level of achievement of these objectives. Further analysis of the data also reveals a valid latent factor reflecting the successful achievement of the ISO 9001 objectives, namely “ISO 9001 effectiveness”.
Research limitations/implications
The present study focuses on food manufacturing SMEs. Therefore, it is worth validating the measurement instrument on large food manufacturing companies, food service companies, companies of specific food sub‐sectors, non‐food companies and finally on companies operating in different economic conditions to Greece.
Practical implications
This measurement instrument can be used by a food manufacturing SME as a self assessment tool and a benchmarking tool. In doing so, suitable strategies can be selected in order for a food SME to improve quality, gain competitive advantage and overcome the current downturn.
Originality/value
In this paper, a measurement instrument is developed and validated in food manufacturing SMEs, based on measures describing the ISO 9001 objectives; in other words, ISO 9001 effectiveness.

Abstract
Purpose
Recent literature emphasizes the application of lean manufacturing practices to food processing industries in order to improve operational efficiency and productivity. Only a very limited number of studies have focused on the implementation of lean manufacturing practices within small and medium-sized enterprises (SMEs) operating in the food sector. The majority of these studies used the case study method and concentrated on individual lean manufacturing techniques geared towards resolving efficiency issues. This paper aims to analyze the status of the lean manufacturing practices and their benefits and barriers among European food processing SMEs.
Design/methodology/approach
A structured questionnaire was developed to collect data. A total of 35 SMEs' representatives, mostly CEOs and operations managers, participated in the survey. The study investigated the role of two control variables in lean implementation: size of the company and country of origin.
Findings
The findings show that lean manufacturing practice deployment in food processing SMEs is generally low and still evolving. However, some lean manufacturing practices are more prevalent than others; e.g. flow, pull and statistical process control are not widely used by the food processing SMEs, whereas total productive maintenance, employee involvement, and customer association are more widespread. The key barriers encountered by food SMEs in the implementation of lean manufacturing practices result from the special characteristics of the food sector, such as highly perishable products, complicated processing, extremely variable raw materials, recipes and unpredictable demand. In addition, lack of knowledge and resources makes it difficult for food processing SMEs to embark on the lean journey.
Originality/value
The gap in the literature regarding the application of lean manufacturing in the food sector is identified and addressed in this study. The originality of this paper lies in analyzing the current status of the use of lean manufacturing practices among food SMEs in Europe and identifying potential barriers.

Abstract
Purpose
The purpose of this paper is to sketch a comparative account of NPD approaches between registered New Zealand food companies that are doing some sort of functional foods (FF) development (Group 1) and those that are not (Group 2); to generate a better understanding of differences and commonalities in their NPD approaches from resource-based view of competitive advantage.
Design/methodology/approach
This paper opted an exploratory approach using a quantitative survey across food manufacturing companies in New Zealand. The primary foci of this empirical investigation were: orientation towards the NPD, innovation processes, collaborative NPD links and routes to commercialisation.
Findings
The results (based on a 22 per cent response rate) show a significant difference (p<0.05) in the aims and mode of NPD between Groups 1 and 2. Further it was observed that food companies in Group 1 have significantly (p<0.05) more diverse external collaborations with broader aims to collaborate, in comparison with food companies in Group 2.
Research limitations/implications
This study was conducted in New Zealand and thus generalisability of the findings may have to be interpreted carefully.
Practical implications
The traditional NPD approach (independent and closed NPD), with loose intellectual property protection practices, dominates the food manufacturing industry in New Zealand. Research-oriented collaborations need to be strengthened in their scope and content to develop the innovative capabilities and capacities of small and medium enterprises (SME's) within future value-added food productions.
Originality/value
This research provides the comparative narration of innovation process of food manufacturing companies with reference to FFs development.

Abstract
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.

Abstract
Purpose
The purpose of this paper is to explore the impact of the effective implementation of both ISO 9001 and ISO 22000 systems on the competitive performance of certified food manufacturing companies.
Design/methodology/approach
A survey instrument was used for quantitative data collection. All items were measured on a seven‐point modified Likert scale. The data were analysed statistically by means of Statistical Package for Social Scientists. Factor analysis and multiple regression analysis were conducted to test the research hypotheses. Both validity and reliability of the measures were checked in order to reduce the measurement error.
Findings
The results show a positive and significant relationship between the combined effective implementation of ISO 9001 and ISO 22000 standards and competitive performance of certified food companies, explaining a significant proportion of variance in their performance.
Practical implications
The results of this study help managers of food companies realize that both the effective implementation of the quality management and quality safety systems ISO 9001 and ISO 22000 lead to increased competitive performance for certified companies. Thus, the paper may motivate the non‐certified food companies to effectively adopt the principles and conform to the requirements of these standards, leading to enhanced manufacturing capabilities and competitive performance.
Originality/value
This paper highlights the influence of quality and food safety management systems on the competitive performance of the certified food manufacturing companies. It reveals the value of the combined effective implementation of ISO 22000 and ISO 9001:2000 systems, proving that, when effectively implemented, they have a favourable effect on companies' performance.

Abstract
Purpose
Statistical process control (SPC) is widely applied for control and improve processes in manufacturing, but very few studies have reported on the successful application of SPC in the food industry, in particular. The purpose of this paper is to critically assess the status of SPC in the UK food manufacturing industry and to suggest future research avenues.
Design/methodology/approach
A research project was carried out in the UK food manufacturing sector through questionnaires. The results of the study were analysed using descriptive statistics and statistical tests to be applied in the hypothesis testing.
Findings
Findings revealed that 45 per cent of the respondents are SPC users and
Research limitations/implications
The study considered only the food manufacturing companies. Future research could be addressed toward the food service and food supply chain.
Practical implications
The paper provides information to food companies in the UK on most common practiced and important quality tools, SPC charts and critical success factors in the food industry. Moreover, the most challenging factors of SPC implementation in the food industry are presented.
Originality/value
This study depicted the current state of SPC practices in the food industry and the process performance in SPC and non-SPC companies is compared.

Abstract
Purpose
This paper offers quantitative evidence on how surplus food, i.e. safe food that is not sold to the intended customers, is generated and recovered within Italian manufacturing and retail firms. The purpose of this paper is to enlighten the process through which the food supply chain firms come to donate surplus food-to-food banks.
Design/methodology/approach
Surplus food and recoverability were defined as the key terms of the problem. In total, 12 exploratory case studies were conducted to segment the manufacturing and retail sectors, to assess recoverability in each segment, and to establish the protocols for descriptive case studies. A multiple case-study approach was used and 83 firms were investigated.
Findings
The primary source of surplus food is shown to result from products reaching the internal sell-by date, i.e. the date by which manufacturers and warehouses must supply perishable products. Donation to food banks is found to be a relevant management practice in the ambient and chilled manufacturing segments and at retail distribution centres, while frozen food companies and retail stores are found to rely nearly exclusively on waste disposal.
Research limitations/implications
The degree to which our findings are specific to Italy is an issue to investigate. Future research should target surplus food management in farming and food services, and assess the cost effectiveness of alternative management channels.
Practical implications
The paper highlights the changes required to increase the amount of food recovered by food banks. It also summarises the steps for establishing a structured procedure for managing surplus food within firms.
Originality/value
The paper offers quantitative evidence on a relatively untapped yet socially relevant topic, i.e. the upstream process of food recovery and donation.

Abstract
This study explored the experiences of quality professionals with the Hazard Analysis Critical Control Point (HACCP) system in the food industry in Canada. Similarities and differences between HACCP and ISO 9000 quality management systems were also highlighted. In this study, qualitative research was undertaken with selected medium to large‐sized food manufacturing companies. In‐depth telephone interviews were performed with quality professionals to allow the researcher the opportunity to elicit expertise and experience that are unique to the respondent. While the study was designed to be exploratory in nature and to form the basis for future research, several themes were identified. First, all companies used HACCP in conjunction with other internal programs such as product testing and supplier qualification to ensure product quality. Second, all companies perceived internal auditing as a way to ensure the quality programs. Finally, companies that had implemented both HACCP and ISO 9000 mentioned two main obstacles, i.e. resistance to change and fear of documentation.
