Abstract

Purpose

The aim of this research is to determine the importance and impact of project-based learning (PBL) on students' knowledge in Lean and Six Sigma courses where practical application of theoretical knowledge is necessary.

Design/methodology/approach

Students teams were given hands-on collaborative projects conducted with local companies. After the completion of the project, a student evaluation survey was conducted and the responses were analysed in two different phases. The first phase consisted of collecting responses from the Lean and Six Sigma courses; observing the impact of the semester project on students' knowledge based on the response percentages. The second phase analyses the responses from both the Lean and Six Sigma courses, by performing a Fisher's exact test to examine how similar the students received knowledge from the use of the semester project.

Findings

Results showed that the inclusion of the semester project in the courses had a positive impact on the students' knowledge in learning course concepts and the students were able to apply theoretical knowledge in solving real-world problems. It is also observed that the response patterns are different in most of the aspects between both the courses.

Research limitations/implications

This research evaluates student learning with statistical tests and is limited only for classroom teaching techniques. Further, this research states that application-oriented courses should be accompanied by projects as it helps in better understanding the course deliverables for the students.

Originality/value

Research evaluating the impact of PBL on students' knowledge in Lean and Six Sigma courses does not currently exist. Statistical analysis of survey responses from both the Lean and Six Sigma courses was performed using a χ2 test of independence to examine how similar the students received knowledge from the use of the semester project.

Abstract

Purpose

The purpose of this paper is to implement the six sigma (SS) strategy in a bag sector under actual operating circumstances based on defining-measure-analyze-improve and control (DMAIC). During the project, several statistical tools and methods have been used efficiently to create inferences. Thus, to measure and enhance system efficiency, the author calculate reliability, availability and maintainability (RAM) indices. Based on this research, the author show how the SS method and RAM analysis are very helpful in determining maintenance intervals, as well as in planning and organizing the appropriate maintenance strategy.

Design/methodology/approach

This study introduces the step-by-step application of the DMAIC methodology for the identification and reduction of bag production line downtime and examines the present operations management. Thus, statistical techniques are used to analyze the failure and repair database. Pareto analysis, histograms and descriptive statistics at the machine and line-level of the historical data were conducted. Trend and serial correlation testing validated the hypothesis of independence and identical distribution of database was performed. In addition, with their best fit allocation, the RAM of both the bag production line and its machines was estimated at separate mission times.

Findings

The main goals of the applied method are to understand the nature of the downtime patterns and to accurately and quantitatively estimate the RAM characteristics of the bag production system. The assessment defines the production line's critical points, requiring further enhancement through an efficient maintenance approach. Therefore, by improving plant efficiency and safety, the author can decrease unplanned downtime and equipment failures.

Originality/value

This research is expected to serve as an attempt to conduct SS DMAIC methodology through RAM assessment and its impact on system efficiency under actual circumstances. The benefit of the methodology is that the manufacturing process is continuously monitored by suitable indicators, the use of which leads to a continuous improvement cycle.

Abstract

Purpose

The purpose of this paper is to capture the status of implementation of Six Sigma in various manufacturing industries and also examine the success of the Six Sigma by using different performance indicators.

Design/methodology/approach

The methodology of critical review involves the selection and classification of 112 research articles on the implementation of Six Sigma in different manufacturing industries. The selected articles are categorized by the following: articles distribution based on the year of publication, publication database, various journals, contribution of authors, continent, scale of industry, implemented approaches, focused industry, tools and techniques used in phases of Six Sigma methodology, and performance indicators used in Six Sigma implementation. Then after, future scopes of research opportunities are derived based on significant findings.

Findings

The literature revealed that: Very few work was undertaken on the implementation of Six Sigma in various manufacturing industries like ceramic, paper, gems and jewelry, cement, furniture, stone, fertilizer, forging, paper and surface treatment industries. Most of the researchers have considered very few performance indicators to identify the improvement after Six Sigma implementation. But, there is no clue regarding overall improvement in different perspectives after the implementation of Six Sigma. The financial indicators, personnel indicators, process indicators and customer indicators are useful to measure the overall improvement after the implementation of Six Sigma in the manufacturing sector.

Research limitations/implications

The study was carried out on the implementation of Six Sigma methodology in various manufacturing industries, and various performance indicators were identified while implementing the Six Sigma methodology. Case studies pertaining to service industries were not covered here.

Originality/value

Very little research has been carried out to measure the overall success of implementing Six Sigma methodology in manufacturing industries. This paper will provide value to students, researchers and practitioners of Six Sigma by providing insight into the implementation of Six Sigma in manufacturing industries.

Abstract

Purpose

The purpose of this paper is to demonstrate the ability to researchers of using design of experiments (DoE) as a structured and systematic approach to performing systematic literature reviews. The authors demonstrate a simple case study illustrating the application of DoE in executing a systematic literature review on two popular topics in higher education: academic leadership and Lean Six Sigma.

Design/methodology/approach

The methodology involves the systematic literature review of linking academic leadership with terms such as Lean, Six Sigma, Total Quality Management, Maturity Model and Continuous Improvement. The main tool used to structure the systematic literature review is a Taguchi Orthogonal Array design, specifically an L16 grid and the method is verified by conducting another review, replacing the term academic leadership with simply leadership.

Findings

The approach identified at first no research papers linking the terms; however, when academic leadership was replaced with university, 19 research papers where discovered. The verification exercise, linking just leadership with the other search string generated over 1,000 results – demonstrating that the tool can find large volumes of articles if they exist, the search was completed for a ten year time frame – 2004 to 2014.

Research limitations/implications

The case study focussed on a field which is known to have little current research and the verification exercise deliberately targeted a known large body of research. The authors will continue to use the approach and refine the technique over time.

Practical implications

This approach would help any researcher despite of their discipline to identify opportunities and gaps in the current literature.

Originality/value

The paper shows how DoE can be used in an academic research-based process. No other literature review approach currently exists which uses Taguchi approach to DoE to filter the search criteria.

Abstract

Samples of sandwiches were taken from all petrol filling stations in the Bolton area selling such foodstuffs. These were bacteriologically examined and, when the results were obtained, all the petrol stations were visited and advice was given where improvements could be made. Resampling was carried out and the results were compared with the initial samples. The second set of results indicated a significant improvement in microbial flora. Further recommendations were made where necessary and it was possible to produce a Code of Practice from the results obtained.

Abstract

Like it or not, change is inevitable if you are to survive. Far better to instigate change than allow other people to inflict it on you. To anticipate the future has to be good to allow time to implement change rather than having to react to it. This appears quite simple, but is it? This special themed issue of Management Decision contains a number of examples of how organizations have managed change. Lessons can be learned from other industries than your own with regard to best practice and basic principles which can then be applied to your own organization..

Abstract

The Howard Shuttering Contractors case throws considerable light on the importance which the tribunals attach to warnings before dismissing an employee. In this case the tribunal took great pains to interpret the intention of the parties to the different site agreements, and it came to the conclusion that the agreed procedure was not followed. One other matter, which must be particularly noted by employers, is that where a final warning is required, this final warning must be “a warning”, and not the actual dismissal. So that where, for example, three warnings are to be given, the third must be a “warning”. It is after the employee has misconducted himself thereafter that the employer may dismiss.

Abstract

A distinction must be drawn between a dismissal on the one hand, and on the other a repudiation of a contract of employment as a result of a breach of a fundamental term of that contract. When such a repudiation has been accepted by the innocent party then a termination of employment takes place. Such termination does not constitute dismissal (see London v. James Laidlaw & Sons Ltd (1974) IRLR 136 and Gannon v. J. C. Firth (1976) IRLR 415 EAT).

Abstract

The Food and Drugs Bill introduced by the Government affords an excellent illustration of the fact that repressive legislative enactments in regard to adulteration must always be of such a nature that, while they give a certain degree and a certain kind of protection to the public, they can never be expected to supply a sufficiently real and effective insurance against adulteration and against the palming off of inferior goods, nor an adequate and satisfactory protection to the producer and vendor of superior articles. In this country, at any rate, legislation on the adulteration question has always been, and probably will always be of a somewhat weak and patchy character, with the defects inevitably resulting from more or less futile attempts to conciliate a variety of conflicting interests. The Bill as it stands, for instance, fails to deal in any way satisfactorily with the subject of preservatives, and, if passed in its present form, will give the force of law to the standards of Somerset House—standards which must of necessity be low and the general acceptance of which must tend to reduce the quality of foods and drugs to the same dead‐level of extreme inferiority. The ludicrous laissez faire report of the Beer Materials Committee—whose authors see no reason to interfere with the unrestricted sale of the products of the “ free mash tun,” or, more properly speaking, of the free adulteration tun—affords a further instance of what is to be expected at present and for many years to come as the result of governmental travail and official meditations. Public feeling is developing in reference to these matters. There is a growing demand for some system of effective insurance, official or non‐official, based on common‐sense and common honesty ; and it is on account of the plain necessity that the quibbles and futilities attaching to repressive legislation shall by some means be brushed aside that we have come to believe in the power and the value of the system of Control, and that we advocate its general acceptance. The attitude and the policy of the INTERNATIONAL COMMISSION ON ADULTERATION, of the BRITISH FOOD JOURNAL, and of the BRITISH ANALYTICAL CONTROL, are in all respects identical with regard to adulteration questions; and in answer to the observations and suggestions which have been put forward since the introduction of the Control System in England, it may be well once more to state that nothing will meet with the approbation or support of the Control which is not pure, genuine, and good in the strictest sense of these terms. Those applicants and critics whom it may concern may with advantage take notice of the fact that under no circumstances will approval be given to such articles as substitute beers, separated milks, coppered vegetables, dyed sugars, foods treated with chemical preservatives, or, in fact, to any food or drug which cannot be regarded as in every respect free from any adulterant, and free from any suspicion of sophistication or inferiority. The supply of such articles as those referred to, which is left more or less unfettered by the cumbrous machinery of the law, as well as the sale of those adulterated goods with which the law can more easily deal, can only be adequately held in check by the application of a strong system of Control to justify approbation, providing, as this does, the only effective form of insurance which up to the present has been devised.

Abstract

USDA direct and guaranteed farm loan programs exhibit significant geographical variation in lending activity. County‐level estimations made using Tobit procedures indicate that use of Farm Service Agency (FSA) farm loan programs is greater in counties with lower per capita income and regions experiencing greater farm financial stress. Use of direct FSA loan programs was lower in counties with fewer private‐sector lenders. Guarantee loan program usage was found to decline when commercial agricultural lenders are absent from the county. FSA loan programs were more highly utilized in counties with an FSA loan service center and in states receiving greater FSA farm loan funding in past years.
