Development of an impact assessment framework for lean manufacturing within SMEs

The main aim of the research work presented in this thesis, is the development of a novel framework with the capability of assessing the impact of implementing lean manufacturing within small-to-medium sized manufacturing firms (SMEs). By assessing the impact of lean implementation, SMEs can make informed decisions on the viability of lean adoption at the conceptual implementation stage. Companies are also able determine their status in terms of lean manufacturing affordability. Thus, in order to achieve the above-stated aim, the following were the main set research objectives; (1) identifying the key drivers for implementing lean manufacturing within SMEs, (2) investigating the operational activities of SMEs in order to understand their manufacturing issues, (3) exploring the current level of lean manufacturing usage within SMEs so as to categorise users based on their levels of involvement, (4) identifying factors that determine the assessment of lean manufacturing, (5) developing an impact assessment framework for justifying lean manufacturing within SMEs, (6) developing a knowledge based advisory system and (7) validating the impact assessment framework and the developed knowledge based advisory system through real-life case studies, workshops, and expert opinions. A combination of research methodology approaches have been employed in this research study. This comprises literature review, observation of companies' practices and personal interview. The data collection process involved ten SMEs that provided consistent information throughout the research project life. Additionally, visitations to three large size manufacturing firms were also conducted. Hence, the framework and system development process passed through several stages. Firstly, the data were collected from companies who had successfully implemented lean manufacturing within their premise. The second development stage included the analysis and validation of the dataset through company practitioners. An impact assessment framework was thus developed with the aid of regression analysis as a predictive model. However, it was realised that there were few correlations between the dataset generated and analysis. The reasons for this were unclear. ,a knowledge based advisory system was adopted to conceptualise, enhance the robustness of the impact assessment framework and address the problem of the imprecise data in the impact assessment process. Three major factors of impact assessment were considered in the framework and the system development process, namely relative cost of lean implementation, a company lean readiness status and the level of value-added to be achieved (impact/benefits). Three knowledge based advisory sub-systems that consisted of the abovementioned factors were built. Results obtained from them were then fed into the final system. The three sub-systems were validated with the original set of data from companies. This enabled the assignment of a number of input variables whose membership functions aided the definition of the fuzzy expert system language (linguistic variables) used. The final system yielded heuristic rules that enable the postulation of scenarios of lean implementation. Results were sought and tested on a number of firms based within the UK, for the purposes validation. These also included expert opinions both in academic and industrial settings. A major contribution of the developed system is its ability to aid decision-making processes for lean implementation at the early implementation stage. The visualisation facility of the developed system is also useful in enabling potential lean users to make forecasts on the relative cost of lean projects upfront, anticipate lean benefits, and realise one' degree of lean readiness.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Assessing the leanness of a supply chain using multi-grade fuzzy logic: a health-care case study

Purpose Numerous and diverse organizations have implemented lean principles and practices, which concentrate on improving the efficiency of business processes by reducing cost, waste, consumptions and effort. However, previous assessments have not focused on the leanness of the supply chain in a health-care setting. This paper aims to introduce a method for assessing the successful implementation of lean principles and tools in a supply chain. Furthermore, this paper validates the method in a health-care organization. Design/methodology/approach This paper starts with an extensive literature review on assessing leanness and using multi-grade fuzzy logic. Then, a conceptual model was developed to measure leanness. The conceptual model was validated by discussing the initial version with select academic experts, especially those who deal with leanness in health-care organizations. After responding to the experts’ valuable comments, the health-care organization that is the focus of this case study was chosen based on two criteria. The first criterion was the organization’s ability to participate in the study, and the second was the organization’s commitment to implementing lean principles. These criteria were important to ensure the organization had the necessary foundation for implementing change initiatives such as lean process improvements. Next, a multi-grade (multi-attributes) fuzzy logic was used for leanness measurement. A leanness index was calculated, and the results were validated using experts from the case study organization. Finally, the weaker areas of the organization’s processes were identified to point the way for further improvements. Findings The assessment indicated that the case study organization is not lean. The organization’s weaker attributes were identified, and improvements have been suggested. Research limitations/implications This study focused on a single health-care organization, which was selected from a limited pool of potential organizations, namely, organizations which are accredited by both the Saudi Central Board for Accreditation of Healthcare Institutions and the Joint Commission International. The scope of future research should be extended to multi-case studies to enhance the findings presented in this paper. This paper’s findings can be used to help decision-makers at health-care providers to implement lean thinking in supply chain processes. Practical implications This research may be interest to practicing supply chain managers, as it proposes what enablers, factors and attributes should be emphasized in lean implementation. The proposed model can work as an assessment tool to identify the gap between the present level of leanness and the desired leanness state so the health-care organization can identify what can be improved. This model enables decision-makers in hospital supply chain to take suitable actions for improving lean implementation level. Originality/value This study makes an original contribution to the body of research concerning lean principles; the study developed a conceptual model for leanness assessment that can be applied to the supply chain of health-care organizations. Indeed, the conceptual model is likely to be useful for assessing leanness outside of the health-care field, which suggests avenues for future research

Entrepreneurial Competition Orientation and Profitability: The Case of a Developing Economy

The main purpose of this paper is to verify the significance of the implementation of competition orientation (CO) as a part of market orientation for the financial performance of the entrepreneurial small and medium – sized companies in a developing economy. The objectives are: 1. To measure the level of each of the variables of the scale (CO 1: The management continuously analyses the strengths and weaknesses of the competitors; CO 2: We regularly use information about our competitors in strategy creation; CO 3: When a competitor launches a campaign towards our market position we take immediate action; CO 4: We target customers where we have or can develop competitive advantage; CO 5: We create our strategy on the basis of detailed and effective competitor analysis.); 2. To determine the average level of CO in entrepreneurial small and medium – sized companies; 3. To prove the effect CO has on profitability. The methodology included both quantitative and qualitative methods and, the research was done in entrepreneurial companies from the food production industry. This research is a part of an ongoing project entitled: “Strengthening the business capacity of women entrepreneurs in Republic of Macedonia, as a developing country”. Primary data was derived from questionnaires and semi-structured follow-up interviews. Secondary data was collected from books, journals and academic articles. Data was analyzed with IBM SPSS19. The conclusions are given on the basis of descriptive and deductive statistics. The results show that companies of different sizes demonstrate diverse level of implementation of CO i.e. medium – sized companies implement higher levels on every analyzed variable of CO than small companies. The results also corroborate the significant relationships among the five dimensions of CO, as well as their relationship with profitability of the analysed companies. Also, a direct influence of the level of CO implementation on business profitability was found. The main limitation of this study is that it analyses a single industry in a given period of time and, the (small) size of the sample. However, the paper has some practical implications: it proves that to achieve higher financial performance small and medium – sized companies must adopt and implement higher level of competitor orientation, as a part of the market orientation process. Also, the measurability of this part of market orientation on the basis of the MKTOR and MARKOR scales makes available a valuable tool for control of its implementation. The value of the paper derives from the verification of the significance of the relationship between CO and profitability, in a different business sector and with a different research subject from those analyzed hitherto by the literature

A framework for implementing lean principles in the supply chain management at healthcare organizations: Saudi's perspective

Purpose The main purpose of this paper is to present lean implementation in hospital supply chain management (HSCM) and propose a new conceptual framework tailored specifically to the needs of Saudi health-care organizations. Design/methodology/approach This paper starts with an in-depth review of existing frameworks or models for lean implementation in health care in general and in HSCM specifically. Based on the literature studies and taking experts’ opinions into account, a new framework for lean implementation in the Saudi HSCM is presented. Findings A new lean implementation framework is offered to decision-makers in the health-care organization for implementing a lean approach in HSCM practices. Research limitations/implications This study focused on health-care organizations, which were selected from hospitals operated by the Ministry of Health and only those hospitals that are accredited by both the Saudi Central Board for Accreditation of Healthcare Institutions and the Joint Commission International. The framework is limited to Saudi health care. Practical implications The lean supply chain management (LSCM) framework is easy to understand and use without much complexity. This simplicity makes the LSCM applicable in health-care settings. Further, LSCM was validated in three different hospitals, and it helped them to identify and improve their non-added activities, thereby readying them for lean deployment in HSCM. Originality/value Little attention has been paid to implementing a lean approach by health-care providers in developing countries. This study presents a new framework that is considered the first of its kind for implementing lean in HSCM in Saudi. This framework could help HSCMs’ decision-makers to implement lean successfully in HSCM practices

Explore and evaluate organisational culture aspects that affecting Lean implementation within manufacturing SMEs: the case of Saudi Arabia

There is a scarcity of research about cultural aspects and organizational culture related to Lean Implementation (LI) (Pakdil and Leonard 2015). In order to addressing the need for Organizational Culture (OC) to better facilitate Lean and propel its success among Small and Medium Enterprises (SMEs) in Saudi Arabia as a case, requires a methodology which supports the research and analysis of OC. Grounded theory, action research and an inductive approach has been selected. Due to the nature of the topic requiring the exploration of culture, it is beneficial to utilise qualitative research which is provided by grounded theory that has been adopted. Thus, adhering to the grounded theory process utilising an issue focused approach, (Sackmann, 1991). Semi-structured interviews, observations and focus-groups were chosen to conduct this exploratory study. 37 aspects have been identified from semi-structured interviews. All these aspects have been aggregated through focus groups to 7 main themes

Practical implications and future research agenda of lean manufacturing: a systematic literature review

Academic literature on Lean Manufacturing (LM) is widely available. However, due to its fragmentation, the contribution of LM from practical and academic perspectives is controversial. This paper establishes the practical implications of LM studies carried out worldwide and identifies novel research streams. A Systematic Literature Review (SLR) of peer-reviewed journal articles was conducted. A total of 401 articles published in 61 journals during 2010-2019 were collected from four major management science publishers. An “affinity diagram” was applied to organize the data into natural and logical themes. Conceptual frameworks concerning LM practical implications and future research agenda were formulated. Meaningful themes of LM practical implications and future research suggestions were revealed and classified into two categories. In category one pertaining to the internal nature of LM, themes related to the pre-implementation, implementation and post-implementation phases of LM were identified. In category two pertaining to the external nature of LM, themes related to the country in which the companies operate, the diverse managerial systems available, and the methodological research approach were identified. The main themes supported in the literature by most references were determined. Finally, respective statements concerning the practical implications of LM and the future research agenda are analytically presented.N/

Critical Success Factors of Lean Six Sigma Deployment in a Semiconductor Manufacturing Firm: A Case Study

The research is to study what is the Critical Success Factor (CSF) that makes a Multinational Company (MNC) in Malaysia successfully deploys Lean Six Sigma 4.0 (LSS 4.0) for its business excellence. The study examines the three major categories and their CSFs to assess what are the most important factors that succeed in the deployment. The CSFs are grouped into three major categories and apply the Fuzzy Analytic hierarchy process (AHP) to analyze the collected data from 30 internal practitioners and consultants. This research revealed that the management initiative category is important in the LSS deployment, followed by involvement and engagement, which involves various parties in the transformation process. In contrast, technology and knowledge are the least critical category. The important CSFs are customer focus, communication, and understanding of the tools and techniques. This research further explores the adoption of IR4.0 in the LSS framework, which is named LSS 4.0, though the result shows it is the least important factor. The study disclosed that CSF prioritization varies by job function; it might depend on the subject’s job requirements and working environment. This research guides managers in semiconductor industries on continuous improvement deployment and transformation by integrating LSS and IR4.0 to plan and design the framework with the important CSFs. It shares the deployment strategy of respective important CSFs in the company as a reference and proposed a guideline for the execution of different CSFs

Lean implementation in small and medium enterprises: Literature review

There have been many literature reviews carried out on Lean implementation (LI) in larger organisations with specific focus on the automobile industry. Lean implementation among Small and Medium Enterprises (SMEs) has not been so extensively researched. This paper attempts to bridge this gap by reviewing the literature that discussed Lean implementation in SMEs with a perspective of identifying the main challenges faced. We applied the Systematic Review Methodology proposed by Tranfield et al. (2003). This methodology allows for more comprehensive and profounder analysis along three stages: planning, conducting, and reporting. For this study, 403 papers were utilized, with their titles, abstracts and keywords separately studied at early stages of the review. These were collated from specific databases that included: ABI/INFORM Global, Taylor & Francis, Emerald, Sage, Inderscince, BSCO Business Source Premier, ScienceDirect and Scopus. The collected information was classified into four categories for more synthesis. The aim of this study is to establish the current position of global understanding of Lean implementation in SME's, including examining the main categories of Lean implementation in the context of SMEs. Next, an inclusive discussion of associated Critical Success Factors (CSFs) for Lean implementation within SME's is established that can be used as guide for SME's owners and managers. Suggestions for future research orientations are thus provided
