A Lean Six Sigma framework for the reduction of ship loading commercial time in the iron ore pelletising industry
© 2016 Informa UK Limited, trading as Taylor & Francis Group. Abstract: Evidence suggests that specifically designed frameworks to implement Lean Six Sigma (LSS) projects to tackle particular problems are more effective than âgenericâ versions. This paper proposes an implementation framework to effectively deploy LSS to improve a key operation and performance indicator, i.e. ship loading commercial time, of one of the largest world producer of iron ore. This article therefore contributes with a refined framework to effectively implement LSS, and documents its successful application and effectiveness within the context of the case organisation. The LSS framework and project contributed in helping the studied organisation to improve both the capability of its ship loading process and commercial time by more than 30%, resulting in operational savings in the range of $300,000 USD per year. The systematic nature of the framework proposed also helped the organisation to establish a standardised routine to improve its operations. Managerial implications exposing the challenges faced during the implementation of LSS are also discussed to serve as lessons learnt to be considered in other LSS projects. Managers and engineers incharge of improving operations and processes can benefit from this paper as it can be used as a guide to direct the conduction of LSS projects and the empirical application of its principles and tools
Uncomfortable truths - teamworking under lean in the UK
A recent contribution in this journal â Procter, S. and Radnor,
Z. (2014) âTeamworking under Lean in UK public services: lean
teams and team targets in Her Majestyâs Revenue and Customs
(HMRC)â International Journal of Human Resource Management,
25:21, 2978â2995 â provides an account of teamworking
in the UK Civil Service, specifically Her Majestyâs Revenue
and Customs (HMRC), focused on the relationship between
recently implemented lean work organisation and teams and
teamworking. Procter and Radnor claim in this work that it
delivers a âmore nuancedâ analysis of lean in this government
department and, it follows, of the lean phenomenon more
generally. Our riposte critiques their article on several grounds.
It suffers from problems of logic and construction, conceptual
confusion and definitional imprecision. Methodological
difficulties and inconsistent evidence contribute additionally
to analytical weakness. Included in our response are empirical
findings on teamworking at HMRC that challenge Procter and
Radnorâs evidential basis and further reveal the shortcomings
of their interpretation
Quality of medication use in primary care - mapping the problem, working to a solution: a systematic review of the literature
Background: The UK, USA and the World Health Organization have identified improved patient safety in healthcare as a priority. Medication error has been identified as one of the most frequent forms of medical error and is associated with significant medical harm. Errors are the result of the systems that produce them. In industrial settings, a range of systematic techniques have been designed to reduce error and waste. The first stage of these processes is to map out the whole system and its reliability at each stage. However, to date, studies of medication error and solutions have concentrated on individual parts of the whole system. In this paper we wished to conduct a systematic review of the literature, in order to map out the medication system with its associated errors and failures in quality, to assess the strength of the evidence and to use approaches from quality management to identify ways in which the system could be made safer.
Methods: We mapped out the medicines management system in primary care in the UK. We conducted a systematic literature review in order to refine our map of the system and to establish the quality of the research and reliability of the system.
Results: The map demonstrated that the proportion of errors in the management system for medicines in primary care is very high. Several stages of the process had error rates of 50% or more: repeat prescribing reviews, interface prescribing and communication and patient adherence. When including the efficacy of the medicine in the system, the available evidence suggested that only between 4% and 21% of patients achieved the optimum benefit from their medication. Whilst there were some limitations in the evidence base, including the error rate measurement and the sampling strategies employed, there was sufficient information to indicate the ways in which the system could be improved, using management approaches. The first step to improving the overall quality would be routine monitoring of adherence, clinical effectiveness and hospital admissions.
Conclusion: By adopting the whole system approach from a management perspective we have found where failures in quality occur in medication use in primary care in the UK, and where weaknesses occur in the associated evidence base. Quality management approaches have allowed us to develop a coherent change and research agenda in order to tackle these, so far, fairly intractable problems
Towards a theory of operational excellence
The term Operational Excellence is widely applied to businesses but the meaning is ill-defined and is often used as a desired goal. This paper provides a comprehensive review of Operational Excellence and starts to address the criticism of its lack of theoretical foundation. The aim of this conceptual paper is to clarify the meaning of Operational Excellent and to identify the underpinning theories and laws, or rules that guide it. Based on the synthesis of the literature using the term âOperational Excellenceâ writings are reviewed against five criteria for a good theory. Our findings show there has been considerable research into identifying common practices and regularities of Operational Excellence but currently there is no single underlying theory of Operational Excellence that meets the criteria for a good theory. From our analysis of the literature we provide some recommendations to address the gaps found. Further research is required to develop a more robust theory of Operational Excellence that will serve to facilitate learning and innovation in next generation management thinking. Future study is also required to identify research that has been carried out that has tested the laws identified in this study. Ideas and input from practitioners would also be required to develop the theory and underpinning laws
Measuring the Intangible Aspects of the Manufacturing Strategy â A Case Study from the Automotive Industry
Exploring perceptions of Lean in the public sector
This paper explores discourses around Lean by examining the perceptions of new users of Lean in the public sector. The paper draws on actorânetwork theory as the basis for exploring what these new users think about Lean and uses data analysis tools to extrude concepts of significance. The data suggests that Lean continues to retain diverse, parallel and competing perspectives. The responses also signal that key concepts of Lean are missing from the discourses, and that this highlights a need to discuss Lean as a mindsetânot just as a set of tools. The paper suggests future directions for research to further explore the issues emphasised by respondents
Lean road transportation â A systematic method for the improvement of road transport operations
Road transportation has become an important factor in international trade and the management of supply chains. However, this form of product logistics has generally been considered inefficient. Traditionally, practical inefficiencies of road transportation have been addressed through mathematical modelling, operations research-based methods, and simulation. This paper presents an alternative systematic approach to improve road transport operations based on lean thinking and the reduction of the seven transportation extended wastes (STEWs). To do this, the paper reviews the extant literature in the area of lean road transportation, providing a structured research definition of the application of lean thinking in road transport operations and hence guidance on the limited research conducted in this field. The systematic lean transportation method is then presented and empirically tested through a case study in a Mexican firm. The results obtained from the case study indicate that the proposed systematic lean method is an effective alternative for the improvement of road transport operations, with the number of distribution routes and distance travelled being reduced by 27% and 32% respectively. The proposed method can be used by organisations as a guide to help them improve their road transport operations. In addition, the paperâs aim is to contribute by stimulating scholars to further study the application of lean thinking and waste reduction in road transport operations
