    Implementing a customised Lean Six Sigma methodology at a compound animal feed manufacturer in Ireland
    (Emerald, 2023-01-27) Trubetskaya, Anna; McDermott, Olivia; Brophy, Padraig
    This study aims to propose a tailored Lean Six Sigma framework providing an accessible Lean Six Sigma methodology for compound feed manufacturers with the aim of mitigating rising costs and increasingly complex demands from customers. A Lean Six Sigma framework was designed combining Lean value stream mapping and Six Sigma structured problem-solving with a case study in an Irish compound feed manufacturer. The study found that the Lean Six Sigma implementation framework provided a simplified approach, which fitted the resource availability within compound feed manufacturing. The study is limited by the constraints of a sole case study in providing empirical evidence of the effectiveness of the framework. Nevertheless, a conceptual Lean Six Sigma model is proposed, which will assist compound feed manufacturers implementing a continuous improvement approach. This paper proposes a simplified approach to the implementation of Lean Six Sigma in agricultural compound feed manufacturers and in small and medium-sized organisations. This is the first such study in Ireland and will add to the body of work on Lean in agriculture and aid other agri-businesses and compound feed manufacturers in understanding how Lean Six Sigma can benefit.

    Global study into the pros and cons of ISO 18404: a convergent mixed method study and recommendations for further research
    (Emerald, 2021-01-24) Antony, Jiju; McDermott, Olivia; Sony, Michael; Powell, Daryl; Snee, Ronald; Hoerl, Roger Wesley
    Purpose The paper aims to investigate the pros and cons of having a standard for lean six sigma developed in 2015. The study follows up on a previous study by Antony et al. (2021) in more depth and aims to provide a more detailed investigation of various aspects of the standard. Design/methodology/approach A sequential mixed methodology was utilised by interviewing a panel of leading academics and practitioners familiar with lean six sigma followed by distributing a survey questionnaire to continuous improvement and operational excellence (OPEX) personnel. Findings The findings indicate that continuous improvement and OPEX professionals have conflicting views of International Standards Organisation (ISO) 18404. A majority of the participants of the qualitative study suggested, whilst supporting the requirement for a lean sigma standard, voiced concerns about the auditability of the standard and whether it is currently “fit for purpose” and proposed that it needs to be revised. Within the quantitative survey, 42% had never heard of the standard, and of the 58% who had heard of it, 90% had read it. Just 10% stated that they had or would apply the standard within their organisations. Just fewer than 50% felt that the standard was fit for purpose which suggests for further refinements of the standard in the future. Finally, 85% of respondents of the quantitative survey suggested for the revision of the standard whilst just 15% felt it should be removed. Research limitations/implications Other than a previous study by Antony et al. (2021), implementation of ISO 18404 in organisations and its benefits as well as empirical study looking into the impact of the standard on corporate performance in the literature were limited. An opportunity to review lessons learnt from a case study on the ISO 18404 standard implementation within an organisation would further enhance the research. Originality/value The paper provides a valuable resource for organisations to obtain insight into a standard in lean six sigma and whether to implement it or not. Furthermore, the results can form the basis of a case for the future revision of the standard by consolidating and strengthening the findings from the first study with more detailed quantitative and qualitative study.

    (MDPI, 2022-11-01) Poornesh, M.; Bhat, Shreeranga; Gijo, E. V.; Bellairu, Pavana Kumara; McDermott, Olivia
    The research aims to produce, model, and optimise the mechanical properties of novel composite material through a structured multidisciplinary approach. The primary objective is to combine materials science, mechanical engineering, and statistical concepts to ensure Design for Manufacturability (DFM) from the industrial perspective. More specifically, the article is intended to determine the optimal mixture components and predictive model of Al-Si alloy with Al2O3 by accommodating multi-responses that enable DFM. The study adopted ASTM standards to prepare and test the novel composite material. Additionally, the Mixture Design of Experiment (DOE) approach was used to design the experimentation and subsequent analysis. In addition, microstructural images, Cox Response Trace plot, and Response Optimiser plot are effectively utilised to draw robust inferences. For multi-response modelling and optimisation, the composite material¿s mechanical properties, like impact strength, hardness, density, and tensile strength, are considered. The study determines that innovative composite material will yield better results when Al-Alloy is 94.65 wt% and Al2O3 is 5.35 wt% from a multi-responses perspective. Further, it provides predictive models with a high level of predictability. Besides, the research shows that novel composite material has better mechanical properties from a practical perspective. The article not only provides the mechanical properties of a new class of material but also shows the effective utilisation of material science and statistical concepts to develop the novel material in a structured manner. This composite material can be used as a replacement for various parts of automobiles and aircraft. Additionally, researchers can use the article¿s modelling and optimisation approach as a paradigm to create durable composite materials.

    How do organizational performances vary between early adopters and late adopters of Quality 4.0? An exploratory qualitative study
    (Emerald, 2023-08-24) Jiju, Antony; Swarnakar, Vikas; Sony, Michael; McDermott, Olivia; Jayaraman, Raja
    This study aims to investigate how early and late adopters of Q4.0 differ in terms of organizational performance. The authors employed a grounded theory approach for interviewing 15 senior managers from diverse organizational contexts throughout the globe as part of their qualitative research methodology. The research's findings were analyzed based on four types of performance: operational, financial, environmental, and social. It was clear that early adopters of Q4.0 were sustaining superior performance in quality over time, even though their investment was significantly higher than that of late adopters. From a financial viewpoint, it was evident that early adopters had a competitive edge over their rivals compared to late adopters. Late adopters have utilized the notion of the circular economy (CE) more effectively than many early adopters in the context of environmental performance in order to establish a green economy and sustainable development. Although the results of the interview indicate that Q4.0 is having some positive effects on social performance, in the authors' view, it is still least understood from an empirical standpoint. The study's findings assist organizations in comprehending the performance differences between Q4.0 early adopters and late adopters.

    (Taylor & Francis, 2023-07-04) O' Mahony, Daniel; McDermott, Olivia; Lynch, Alan; Cormican, Kathryn
    Serialization technology was introduced to protect the pharmaceutical supply chain from falsified and substandard medicines infiltration. The implementation of serialization systems required a substantial investment by pharmaceutical manufacturers. This study investigated the impact of Serialisation on operational efficiency and productivity in the pharmaceutical industry. A literature review demonstrated limited publications on Serialisation concerning its costs and effects on packing line operational efficiency and productivity. Therefore, a literature review was carried out to assess the relationship between Serialisation, operational efficiency, and productivity. The study revealed that Serialisation had the potential to impact pack line Operational Equipment Effectiveness negatively and line availability, as well as the unit cost of packaged pharmaceuticals and that actual capital costs of Serialisation were greater than the costs originally outlined by policymakers. In addition, the study identified a trend where pharmaceutical sites move away from smaller batch production and toward larger batches to gain greater efficiencies.

    An enhanced phenomenological model to predict surface-based localised corrosion of magnesium alloys for medical use
    (Elsevier, 2023-01-05) Quinn, Conall; Van Gaalen, Kerstin; McHugh, Peter E.; Kopp, Alexander; Vaughan, Ted J.; Irish Research Council; Horizon Europe
    This study developed an enhanced phenomenological model for the predictions of surface-based localised corrosion of magnesium alloys for use in medical applications. The modelling framework extended previous surface-based approaches by considering the role of β-phase components throughout the material volume to better predict spatial and temporal aspects of surface-based corrosion in magnesium alloys. This enhanced surface-based corrosion model offers many advantages as it (i) captures multi-directional pitting, (ii) captures various pit morphologies, (iii) eliminates mesh sizing effects, (iv) reduces computational cost through custom time controls (v) offers control of pit sizing and (vi) produces corrosion rates that are independent of pitting parameter values. The model was fully implemented in three dimensions within the finite element framework and shows excellent potential to enable robust predictions of the long-term performance of magnesium-based implants undergoing corrosion.

    (Emerald, 2023-05-12) McDermott, Olivia; O Dwyer, Kevin; O'Dwyer, Kevin; Noonan, John; Trubetskaya, Anna; Rosa, Angelo
    This project aims to improve a construction company's overall project delivery by utilising Lean Six sigma methods combined with Business Information Modeling (BIM) to design, modularise and manufacture various building elements in a controlled factory environment off-site. A case study in a construction company utilised Lean Six Sigma methodology and BIM modelling to identify non-value add waste in the construction process and improve sustainability. An Irish-based construction company manufacturing modular pipe racks for the pharmaceutical industry utilised Lean Six Sigma to optimise and standardise their OSM partner's process and leverage BIM to design skids which could be manufactured off-site and transported easily with minimal on-site installation and rework required. As a result, productivity was improved, waste and defects were reduced, and less energy was consumed. The case study focused on one construction company and product type. Further case studies would ensure more generalisability. This is one of the few studies on implementing OSM utilising Lean Six Sigma and BIM in an Irish construction company. The detailed quantitative benefits and cost savings calculations presented, as well as the use of the LSM methods & BIM in designing an OSM process, can be leveraged by other construction organisations to understand the benefits of OSM.

    The challenges for manufacturers of the increased clinical evaluation in the European medical device regulations: A quantitative study
    (Springer, 2023-05-17) Kearney, Breda; McDermott, Olivia
    The European Union Medical Device Regulations 2017/745 entered into force on May 2021 with changes related to strengthening the clinical evaluation requirements, particularly for high-risk devices. This study investigates how the increased requirements on medical device manufacturers in relation to how clinical evaluation will challenge manufacturers. A quantitative survey study was utilized with responses from 68 senior or functional area subject matter experts working in medical device manufacturing Regulatory or Quality roles. The findings from the study demonstrated that the highest source of reactive Post-Market Surveillance data was customer complaints and proactive data were Post-Market Clinical Follow-Up. In contrast, the top 3 sources for generating clinical evaluation data for legacy devices under the new Medical Device Regulations were Post-Market Surveillance data, Scientific literature reviews, and Post-Market Clinical Follow-Up studies. Manufacturers¿ biggest challenge under the new Medical Device Regulations is determining the amount of data needed to generate sufficient clinical evidence, while over 60% of high-risk device manufacturers have outsourced the writing of their clinical evaluation reports. Manufacturers also reported a high investment in clinical evaluation training and highlighted inconsistencies in the requirements for clinical data by different notified bodies. These challenges may lead to a potential shortage of certain medical devices in the E.U. and a delay in access to new devices, negatively impacting patient quality of life (1). This study provides a unique insight into the challenges currently experienced by medical device manufacturers as they transition to the MDR clinical evaluation requirements and the subsequent impact on the continued availability of medical devices in the E.U.
