      To ensure manufacturing organisations remain competitive, most of them are turning to total productive maintenance (TPM) and lean manufacturing to ensure seamless operations. Overall equipment effectiveness (OEE) is the foundation of these two business improvement strategies as it tackles the underlying losses that impede equipment efficiency. This study presents the prevalence of managerial issues related to the implementation and use of OEE in the manufacturing industry. To do this, five hypotheses and four research questions were formulated and tested using a combination of descriptive statistics and cross-tabulation, chi-square, analysis of variance, Tukey’s pairwise comparison, Z-test and correlation tests. Data were collected through a survey questionnaire responded by 139 manufacturing organisations worldwide. The results establish, among other ‘soft’ aspects, the linkage of the OEE implementation with that of TPM and lean manufacturing, and the drivers, most critical factors, barriers and the role of management in its implementation. The study also identifies how manufacturing organisations employ the information provided by OEE and how the data for its computation are collected. This study supports the very limited empirical research on the implementation and use of OEE. Thus, this research provides organisations, and their managers, with a better understanding of different factors that affect the successful deployment and management of this highly used measure in industry.
    • A conceptual framework for the implementation of quality management systems

      Garza-Reyes, Jose Arturo; Rocha-Lona, Luis; Kumar, Vikas; University of Derby (Taylor and Francis, 2014-06-25)
      Some evidence suggests that Quality Management Systems (QMSs) make a positive contribution towards the competitiveness of organisations. However, evidence also suggests that organisations find their implementation difficult, and in many cases they are unsuccessful. This paper presents a conceptual framework that systematically guides organisations through a five-stage process to effectively implement and/or improve their QMSs and core business processes. The framework can be modified or amended to be adapted to the needs of specific industries and organisations. The paper discusses some of the main issues associated with the implementation of QMSs and summarises some of the frameworks and models that have been suggested for this purpose. Then, the paper explains, in detail, all the stages and activities of which the proposed conceptual framework consists. This paper's main contribution consists of the proposal of an alternative and novel approach for the implementation/improvement of QMS and business processes.

      Supply chain Integration has emerged as a major field of interest over the years that involve the strategic alignment of functions and processes within an organization. However, there have been major debates regarding the true design of the kinds of integration that would lead to performance of supply chains. This study develops a conceptual framework from the literature and defines four constructs of integration (customer, supplier, internal, and information integration) to see how this would lead to improved supply chain performance (such as production flexibility, inventory turns, order fulfillment rate, total logistics costs, and operational performance).

      Garza-Reyes, Jose Arturo; Forero, Juan Sebastian Beltran; Kumar, Vikas; Villarreal, Bernardo; Cedillo-Campos, Miguel Gaston; Rocha-Lona, Luis; University of Derby; University of Warwick; University of the West of England; Universidad de Monterrey; et al. (Elsevier, 2017-09)
      This paper documents a case study where the transport operations of a word leading provider of paper-based packaging solutions operating in Bogota, Colombia, were measured and improved using lean concepts, methods and tools. The methodology consisted of: (1) direct observations of the transport operations; (2) collection and analysis of data; (3) creation of a Transportation Value Stream Map (TVSM); (4) measurement of the Transportation Overall Vehicle Effectiveness (TOVE); and (5) proposal of improvement recommendations. The TVSM identified six wastes: waiting, resource utilisation, excess movement, over-production, over-processing and behavioural. The TOVE measure resulted in an efficiency of 54%. The study proposed improvement recommendations based on the results of the TVSM and TOVE.
    • An integrated approach of six sigma and QSAM methodologies for a pharmaceutical company: a shipment improvement process.

      Rocha-Lona, Luis; Alvarez- Reyes, Silvia Edith; Garza-Reyes, Jose Arturo; Kumar, Vikas; National Polytechnic Institute, Mexico City; University of Derby; University of the West of England (Inderscience Publishers, 2015-09-17)
      This paper presents a shipment improvement project in a pharmaceutical company to reduce distribution costs of a set of products shipped to Germany. The project consisted in the diagnosis and improvement of the shipment process through the deployment of quick scan audit methodology (QSAM) as a precursor to Six Sigma implementation. The original sample-shipments process was analysed to improve it and achieve the targets based on optimised sub-processes. The results showed a set of non-value added activities in transportation, motion, waiting, defects and the sub-utilisation of people. Based on the application of quality tools such as VSM, CFD, VOC, CTQ-Three under the Six Sigma approach, the improvements achieved a 26% reduction in cycle time, and no complaints from customers were reported since the implementation. A control plan was deployed to track shipments and maintain open and close communication with the customer. The resulting benefits had a significant impact on reducing distribution costs.

      Chugani, Nashmi; Kumar, Vikas; Garza-Reyes, Jose Arturo; Rocha-Lona, Luis; Upadhyay, Arvind; University of Derby (Emerald, 2017-01)
      Purpose - The academic literature and research lines exploring the effect of quality improvement methods on environmental performance still remain in early stages. The purpose of this study is therefore to investigate, through a systematic review of the existing academic literature, the environmental (green) impact of using quality and operations improvement methods such as Lean, Six Sigma, and Lean Six Sigma. This includes the impact on energy saving and the usage of natural resources. Design/methodology/approach - This study follows a systematic literature review approach through which it analyses research papers published in top 16 operations and quality management journals. No specific time frame was established, but a set of keywords were used to shortlist the articles. A sample of 70 articles was finally shortlisted and analysed to provide a discussion on environmental concerns related to Lean, Six Sigma, and Lean Six Sigma. Findings - The comprehensive review of shortlisted articles indicates that both Lean and Six Sigma can be considered effective methods to support the conservation of resources, combat global warming and saving energy. Various scholars provide evidence of this and as such, organisations should not only consider these methods to manage quality and improve operational performance but also meet environmental regulations. A set of research questions that demands further investigation has also been proposed based on the findings of this research. Research limitations - This study is limited to a sample of 70 articles collected from top 16 operations and quality management journals. The search of journals is also limited to a set of key words (‘Lean’, ‘Green’, ‘Six Sigma’, ‘environment’, ‘sustainable’ and ‘sustainability’) used to shortlist the sample size. Practical implications - The study shows that organisations can consider the adoption of Lean, Six Sigma and Lean Six Sigma to meet environmental regulations, save costs and also meet quality management standards. This will contribute in helping organisations to formulate more effective and inclusive strategies which do not only consider the quality and operational dimensions but also the environmental dimension. Originality/value - Literature exploring the environmental/green impact of quality management methods commonly used in industry is limited. There is also a lack of studies aiming to investigate the green impact of Lean and Six Sigma in top operations and quality management journals. The study focusing on investigating the green impact of Lean, Six Sigma and Lean Six Sigma methods altogether is also a research first of its kind.
    • Lean Manufacturing and Internet of Things – A Synergetic or Antagonist Relationship?

      Anosike, Anthony; Alafropatis, Konstantinos; Garza-Reyes, Jose Arturo; Kumar, Anil; Luthra, Sunil; Rocha-Lona, Luis; University of Derby; University of Warwick; London Metropolitan University; Ch. Ranbir Singh State Institute of Engineering & Technology, Jhajjar-124103, Haryana, India; et al. (Elsevier, 2021-04-13)
      This paper explores the relationship between five LM methods (JIT, TPM, Autonomation, VSM and Kaizen) and three IoT technologies (RFID, WSN and Middleware) and the implications that arise from their combination. Four hypotheses and four complimentary research questions were formulated and tested. 136 responses were obtained through a questionnaire survey and analysed using descriptive statistics, 2-Sample proportion, Kruskal-Wallis, ANOVA and Pairwise comparison tests. The findings indicate that IoT can significantly improve the operational performance of manufacturing organisations. The findings advocate that all LM methods, apart from Kaizen, benefit from improved effectiveness by combining them with IoT. The results suggest that this can be attributed to the general perception about IoT, which despite the support and benefits it provides to people, is seen to be reducing human involvement whereas Kaizen is seen to be more people-focused. Improvements in information flow, decision-making and productivity were also found to be the most important motivations and benefits of combining LM methods with IoT. The findings of this research can be used by LM organisations that wish to embark into the new digitalised manufacturing era and businesses seeking to improve their performance through the combination of traditional efficiency-based methods and I4.0 technologies.
    • Lean readiness level of the Azerbaijan construction industry

      Aghayev, Hajibaba; Kumar, Vikas; Rocha-Lona, Luis; González-Aleu, Fernando; Nadeem, Simon; Garza-Reyes, Jose; University of Warwick; University of Derby; University of the West of England; Instituto Politécnico Nacional, Mexico; et al. (IEOM Society, 2020-03)
      This paper identifies and measures the Lean readiness of the Azerbaijan construction industry. A survey questionnaire was utilised to evaluate the Lean readiness of this industry by measuring its quality practices and to test three hypotheses. The Lean readiness framework developed by Al-Najem et al. (2013) was taken as a basis for this study; however, there can also be seen some adaptations made from the framework developed by Diekmann et al. (2003). The questionnaire was sent to 57 Azerbaijan construction companies, from where 20 responses were obtained. The results derived from the questionnaire showed that the Azerbaijan construction industry is not ready to implement the Lean methodology. It also found that there remains a lack of trust between employee and employer relations. Lastly, it is evident that the size of the companies does not play any considerable role on Lean readiness of construction companies and does not make any sense for choosing construction prerequisites. This study can be beneficial for those Azerbaijan construction companies that are interested in the implementation of Lean construction, or which are interested to increase their level of competitiveness.

      Meza-Ruiz, Itzel D.; Rocha-Lona, Luis; del Rocío Soto-Flores, María; Garza-Reyes, Jose Arturo; Kumar, Vikas; Lopez-Torres, Gabriela Citlalli; Instituto Politécnico Nacional; University of Derby; University of the West of England; Ciudad Universitaria Aguascalientes (Elsevier, 2017-09)
      There has been an increasing interest in corporate sustainability (CS) and how companies should strive for it in order to satisfy stakeholders’ demands concerning social, economic, and environmental impacts. The purpose of this paper was to identify the best sustainability practices and the sustainability maturity levels that allow manufacturing and service companies to contribute to sustainable development in the long run. Based on a qualitative approach, a comparative study of five large companies was deployed in order to determine their sustainability maturity levels and best practices. The research method consisted of a critical review of the literature and category analysis concerning corporate sustainability trends and some of the best well-known performance frameworks such as the Global Reporting Initiative (GRI), business excellence models (BEMs), and international standards. The main findings reveal that companies’ sustainability maturity levels range from satisfactory to sophisticated in several sustainability aspects. Best sustainability practices found in this sample include the use of certifications such as ISO 9000, ISO 14001, GRI, and CSR, among others, combined with the systematic use of BEMs over many years. Finally, several key processes such as self-assessment, benchmarking, corporate reporting, strategic planning, and systematic training were found to be significant in helping manufacturing and service organisations achieve their business sustainability objectives.

      Maldonado-Guzman, Gonzalo; Garza-Reyes, Jose Arturo; Rocha-Lona, Luis; Kumar, Vikas; Centro de Ciencias Económicas y Administrativas; University of Derby; Instituto Politécnico NacionalESCA Santo Tomás; University of West England (Springer, 2017-08-29)
      This empirical research investigates the influence of service innovation on the performance of service SMEs, especially within the context of a country with an emerging economy as it is the case of Mexico. Data were collected through a survey instrument designed and distributed among service SMEs in the Aguascalientes state of Mexico to test a hypothesis formulated from the literature review conducted. The instrument was validated using Confirmatory Factor Analysis, Cronbach’s alpha test and the Composite Reliability Index to ensure its reliability. The hypothesis was tested using structural equation modelling (SEM) using an as input 308 valid responses obtained from the survey. In general, the results obtained show that service innovation has a positive and significant effect on the performance of service SMEs. Specific research related to service innovation in service SMEs is limited. This paper therefore fills this research gap by expanding the limited body of knowledge in this field.
