This paper unifies previous research literature on employee participation in continuous improvement (CI) activities through the development and validation of a conceptual model. The purpose of this model is to illustrate how organizational drivers foster organizational and individual enablers which, in turn, strengthen employee participation in CI. The article also discusses the results and managerial implications.

Firstly, the article introduces the main variables affecting employee participation in CI, looking at the different possible relationships proposed in existing literature. In accordance with the Kaye and Anderson (1999) framework, these variables are categorized into organizational drivers, organizational and individual enablers and individual outcomes. Based on these categories, a model was put forward and empirically validated using data collected from three Spanish companies (n = 483) and using partial least squares structural equations modelling (PLS–SEM).

A model was put forward, proposing PIRK systems (power, information, rewards, knowledge) as the main organizational driver of employee participation in CI activities. PIRK impacts positively on social influence (organizational enabler), self-efficacy and job satisfaction (individual enablers). These enablers, together with employee intention of participating, help determine employee participation in CI activities.

Organizations with CI programmes should develop systems based on employee empowerment, information, rewards and knowledge in order to foster their self-efficacy and seek out a culture where social influence may help to improve job satisfaction. By suitably managing these organizational drivers, managers can help to further develop certain organizational and individual enablers responsible for fostering employee participation in CI activities.

By unifying different behavioural and CI-related frameworks, this paper carries out an in-depth study into the process of fostering employee participation as the key aspect in helping organizations sustain CI programmes. This paper shows the importance of managing PIRK organizational drivers as levers in the process of developing certain organizational and individual enablers, which are responsible for enhancing employee participation in CI.

Despite significant amounts of environmental management tools that are available for companies to use, no model guides them toward environmental excellence. As a consequence, the purpose of this paper is to develop an environmental management maturity (EMM) model that helps companies that are on the path toward environmental excellence.

An iterative process was used to develop this model, starting with some semi-structured interviews with 19 companies within the Basque Country and two workshops with environmental experts. Following these steps, the initial version of the model was developed. Data from subsequent surveys carried out in Spanish and Italian companies, and a survey and semi-structured interviews in companies in the UK were incorporated into the model, yielding the final, more robust version of the EMM model.

The EMM model proposes six maturity stages: legal requirements, responsibility assignment and training, systematization, ECO², eco-innovative products and services, and leading green company. Each stage details a series of elements: description, agents involved, policies, tools, indicators, structure, and behavior over time graphs. This research confirms that a company’s environmental management evolves through several distinctive stages, regardless of the industrial sector.

The proposed model concludes that the defined maturity stages provide valuable guidance for industrial firms as it helps them identify their maturity stage as well as the steps they should follow to move to the next stage.

Green Lean tools are aligned with the Circular Economy strategy as they aim at reducing waste, however, they miss the creation of value through waste. Therefore, this paper investigates whether the current implementation of the Green Lean strategy promotes the introduction of the Circular philosophy to achieve sustainable management production processes. It analyses how the resources were managed by implementing the different strategies and tools presented in Green Lean case studies under the lens of Circular Economy and highlights future research paths on the Circular Lean integration.

An analysis of the implementation of Green Lean case studies, selected through a Systematic Literature Review, from the manufacturing sector is conducted.

The majority of Green Lean implementations were aimed at minimizing waste, which is aligned with the narrowing strategy of Circular Economy and only a few cases studies aimed at closing the production cycles. Even though the main results indicate that being eco-efficient is a good starting point to move towards sustainability, from a Circular Economy point of view, this approach could remain limited. Therefore, the current contribution of Green Lean to the implementation of circular practices is limited. It can be concluded that introducing the circular philosophy in the Green Lean methodology can be achieved through redirecting Green Lean from waste reduction towards a value creation focus.

The originality of this paper is that it provides a critical review of the literature on the topic of Green Lean integration and Circular Economy.

The purpose of this study is to critically evaluate the current status of Design of experiments (DoE) in the service industry or non-manufacturing processes in the manufacturing sector. This involves the identification of critical success factors and challenges in the use of DoE in the context of the service industry as well as the key skills needed for its successful applications.

In order to identify the critical success factors and challenges, an online survey instrument was developed and distributed across Six Sigma Black Belts (SSBB), Six Sigma Master Black Belts (SSMBB), process improvement champions, continuous improvement professionals, DoE experts and specialists as well as academics who are involved in DoE research and applications.

A total of 109 participants from over 20 countries responded to the study. One of the first findings of the study is that over 40% of the process improvement professionals in the service sector do not have any hands-on experience with the application of DoE. Further, this study highlights the following critical factors for successful DoE applications: dedicating adequate resources in terms of time, budget and people for the experiment; getting a clear understanding of the problem at hand; securing a reliable and validated measurement system for measuring the response or quality characteristics of interest; and identifying input independent variables, which influence the quality characteristics during the brainstorming stage. Some respondents also mention the importance of having training or education in DoE as a critical success factor. At the same time, the lack of adequate planning to experimentation, mathematical knowledge and statistical reasoning remains as challenge to be solved.

As data were collected at an individual level, inter-reliability, which measures the consistency of judgements on a particular survey item, could not be gauged. Moreover, due to low sample size across some continents, an intercontinental comparative study on the extent of the application of DoE across various continents could not be performed.

To the best of the authors’ knowledge, this is the first global survey carried out to understand the status of DoE in the service industry. The results of the global study can be used to encourage quality, continuous improvement and process improvement professionals in the service sector to drive wider acceptance of one of the most powerful tools in the Six Sigma toolkit for problem-solving scenarios. Moreover, senior managers in the service industry can take away some of the key benefits, challenges and success factors in the implementation of DoE.

The purpose of this paper is to analyze gaps and trends, as well suggest approaches and methodologies that should be addressed by future studies for implementing the lean and green management in the agri-food sector.

Based on a sample with 117 papers, this paper presents a systematic review on the integration of lean and green in the agri-food sector.

Key findings indicate that research on lean and green topics has increased in recent years, an important gap in the integration of lean and green in the agri-food sector has been identified. Two paths that remain open for further research are detected: the lack of theoretical, prescriptive and quantitative research and the possibility of integrating the two most used tools of lean (i.e. value stream mapping) and green (i.e. life-cycle assessment).

This study does not only advance the theoretical knowledge of the lean and green field, but it is also beneficial for agri-food companies who aim to effectively deploy lean and green in their processes in order to improve both operational and environmental performances.

No other industry matches in such a complete way the agri-food industry’s challenge of sustainability that is due to the amount of resources it consumes and its interrelatedness with the well-being of humanity.

There are separate streams of established research on lean and green management in the agri-food sector, yet very few authors have addressed the intersection of these strategic initiatives.

The purpose of this paper is to develop a methodology that is based on the concept of environmental comfort and can serve as a tool that can help companies and employees to implement Kaizen projects. This methodology focuses on the worker’s participation in analyzing and developing improvements related to their workplace.

This research is focused on the development of a methodology that encourages worker participation in improvement activities, through the analysis of their working conditions. For this purpose, the proposed methodology was developed in accordance with the dimensions of workplace comfort proposed by Vischer. The employees start working on the analysis of problems and their solutions through the logical framework approach, as it is a tool that encourages worker participation and consensus. The developed methodology was applied in a company, with three different groups of people, which enabled the authors to test its utility.

The findings reveal that the proposed methodology is effective in initiating workers in the path of Kaizen. The employees who applied this methodology were able to propose improvement actions that addressed the problems and opportunities that they had previously detected. Moreover, the questionnaire that was used to validate the methodology and was administered to employees shows that the methodology is useful in preparing them for adopting continuous improvement (CI) programs.

The methodology presented in this paper has been applied and evaluated by a small number of employees. These limitations suggest future research recommendations.

This participatory methodology could be used by different types of companies to initiate employees on the path of CI, even if they are not familiar with improvement programs or methodologies. In addition, its use could improve the capabilities of employees in areas such as participatory analysis, problem identification and proposal of objectives. These capabilities are necessary in any Kaizen project. As a result of the application of this methodology, the companies could obtain a list of areas of improvement related to their work and propose actions to work on.

The paper presents the use of environmental comfort in the workplace as the first step in accomplishing a Kaizen project, with a focus on the employee involvement and consensus.

Environmental management (EM) is becoming increasingly important in all types of organizations. The food industry represents the top industrial sector of the Spanish economy; however, there is still little knowledge about how it is managed environmentally. The purpose of this paper is to present a descriptive analysis of the Spanish food sector.

This study undertook a descriptive analysis based on probabilistic sampling surveys from food companies in Spain. The survey was sent out to 900 companies obtaining 128 answers.

The results of this study show that companies with an EM standard tend to have a more developed system and a greater presence of EM tools and actions. Moreover, statistical differences were identified among the characteristics of companies and various factors that affect the evolution of their EM.

There are no studies that reveal a clear picture of the status of EM in the Spanish food industry. This study presents a clear starting point that might help policy makers, consultants, researchers and other parties to set new improvement routes so companies do not get stuck in their progress toward environmental excellence.

The purpose of the article is to present the results of a critical literature review (CLR) on Design of experiments (DoE) in the service industry.

A critical review of existing literature review across various databases including Scopus, Web of Science, Google Scholar and Emerald Insight were searched for the identification of relevant papers. The authors searched relevant journal articles for a time period of 25 years (1994–2019).

A total of 29 industry case studies of DoE applications were identified spanning healthcare, retail, logistics, education, marketing, after sales and catering business. The industrial experimentation strategies adopted by the case study organisations were screening, factorial designs, Taguchi, response surface method and split-plot. It was apparent that there are only a handful number of papers showing the applications of DoE across the service sector and this motivates for pursuing further research into this topic by the authors.

The findings of the study can be very useful for middle and senior managers to understand the benefits of implementing this powerful technique for increased understanding of service processes, as well as for optimising service performance. Moreover, the paper presents some of the fundamental challenges, as well as skills needed for the successful application of DoE.

To the best of our knowledge, this is the first CLR on DoE and its applications in the service sector. The findings of the study can be beneficial to both academic and industrial communities to understand some of the challenges and fundamental gaps which need to be tackled in the future.

The purpose of this paper is to describe a readiness programme designed to increase employees’ awareness of order and cleanliness as a way of building the necessary foundation for implementing and sustaining continuous improvement processes. In this paper, the authors propose a new readiness programme based on the principles of 5S, with the aim of strengthening employees’ motivation and involvement prior to 5S being implemented.

The research is based on case study methodology, followed by a programme of four structured activities. The validity of the programme is shown through the implementation of the activities in two different organizations.

The readiness programme was applied before 5S was successfully implemented. The degree of awareness and motivation of the programme participants improved as a result of these activities. Moreover, the activities increased people’s motivation to participate in improvement activities.

Applying a readiness programme before implementing 5S can help organizations to achieve and sustain improvement activities, thus increasing worker commitment and motivation.

Companies use continuous improvement (CI) as a strategy to achieve business excellence and innovation. Yet CI initiatives fail mostly due to a lack of employee engagement. The paper aims to discuss this issue.

Based on the CI literature and the technology acceptance model (TAM), a comprehensive model called continuous improvement acceptance mode (CIAM) was developed to understand the main organisational antecedents that predict employee intention to participate in CI. The CIAM is based on structural equation modelling using partial least squares and it was validated in a large manufacturing plant in Europe.

Emulating the findings of the TAM, this study shows that employee intention to participate can be predicted by two variables called ease of participating and usefulness of participating. The CIAM then relates these constructs with relevant CI enablers found in the CI literature.

The CIAM could help academics and practitioners to better understand employee participation in CI activities, allowing CI systems to be better designed and achieve long-term sustainability.

The CIAM presents new variables and interactions that help to understand employee participation in CI activities. Some of these variables and interactions have received scant attention in the CI literature and thus they are worth investigating in greater depth in the future.
