Inaccurate Estimate

Many product characteristics are qualitative in nature, e.g. colour, brightness, surface finish etc. The manufacturing process of such products is usually described in terms of fraction nonconforming or conforming which is assumed to follow binomial distribution. Measuring capability of a binomial process implies assessing to what extent the fraction nonconforming or conforming in the continuous stream of lots conform to the specification limits. The Cp or Cpl of a binomial process can be estimated using several approaches. However, these approaches generally give widely varying assessment about the capability of a given binomial process. Consequently, a user of the index may inadvertently be led to erroneous decision making based on an inaccurate estimate of the index. In this paper, a procedure is proposed for assessing accuracies of estimates of Cpu or Cpl obtained by different methods. Subsequently, the best method for evaluating capability of a binomial process is identified based on analysis of multiple case studies, and also the methods giving inaccurate estimates are highlighted. Keywords: Process capability index, binomial process, fraction nonconforming, nonconforming lot (NL), predicted NL%, prediction error

Early Phases

Abstract Radio Frequency Identification (RFID) is still a relatively new technology for many manufacturing and logistics companies. These companies experience uncertainties about RFID implementation, so they take steps to mitigate them. This article presents multiple case studies to design a conceptual framework to mitigate such barriers. The goal of this research was to test propositions that companies: often are not convinced about the maturity and performance of RFID technology; perform typical actions to test uncertainties; and need proof of the benefits of RFID technology before implementation. It was demonstrated that companies conduct proof of RFID technology activities (demonstrations and reference visits) to test RFID performance. These are required to test the technology in operation. Conclusions of this research may serve RFID systems providers and end users of technology by facilitating a better understanding of decision making processes during early phases of RFID implementation.

Universities in the state are regarded as ‘small cities’ due to their large size, population, and the various complex activities taking place in campuses, which have some serious direct and indirect impacts on the environment. The current study focuses on the green practices in state universities of Haryana. The comparative analysis has been done between the multiple case studies and find out the best green practices being adopted in universities for moving towards making the green campus and recommend the area of improvement for making environment sustainable campus.

Creating autonomous learners in the teaching of English as a second language (ESL) in Zimbabwean secondary schools : a reality or a myth?

Comprehensive Framework

This study explored the utility of the learner autonomy concept in the Zimbabwean O Level English as a Second Language (ESL) classroom focusing on three Gweru urban high schools of the Midlands Province. The researchers intended to establish whether learner autonomy was a reality or just a myth in Zimbabwean classrooms. A qualitative multiple case study design was applied focusing on teaching strategies, availability of resources, challenges faced and ways of optimising it. Questionnaires and document analysis were used for data collection. The findings revealed that the concept did not manifest in explicit terms, the learners did not participate in decision making, and the teachers were not adequately prepared to administer autonomous processes with students. For it to be a reality, the Education Ministry is recommended to establish a comprehensive framework of how autonomous learning should be implemented. Teacher training should explicitly focus on how to develop autonomous learners. Teachers ought to be flexible enough to accommodate learners' contributions towards their learning.

Shed Light

Despite the popularity of distributed leadership theory, the investigation of the micro-political aspects of such models have scarcely been explored, and insights on the cultural variety of distributed practices in schools are limited. The present study aimed to explore what micro-political aspects emerge in participative decision making in collectivist and individualist cultures. To this end, a multiple case study method was adopted, focusing on four Israeli public high schools. Schools were chosen to represent an ‘extreme’ case selection rationale: two non-religious urban schools representing individualist cases, and two communal schools in religious kibbutzim representing communal schools. The analysis shed light on three micro-political points of comparison between the prototypes of participative decision making in collectivist and individualist cultures related to control, actors, and stage crafting. The findings and implications are discussed.

Industry Relatedness

Context: The coronavirus disease 2019 (COVID-19) pandemic led to a turbulent business environment, resulting in market uncertainties, frustrations, and rumors. Wrongly held beliefs—or myths—can hinder startups from turning new market opportunities into their favor (for example, by failing at diversification decisions) or undertaking wrong business decisions, e.g., diversifying in industries that have products of no real market value). Objectives: The objective of the paper is to identify the beliefs that drive the business decisions of startups in a pandemic and to isolate those beliefs that are merely myths. Further, this paper proposes strategic guidelines in the form of a framework to help startups make sound decisions that can lead to market success. Method: The two-step research method involved multiple case studies with five startups based in India, France, Italy, and Switzerland, to identify perceptual beliefs that drove strategic business decisions, followed by a case study of 36 COVID-19-solution focused startups, funded by the European Union (EU). The findings were validated through a survey that involved 102 entrepreneurs. The comparative analysis of two multiple case studies helped identify beliefs that were merely “myths”; myths that drove irrational strategic decisions, resulting in business failures. Results: The results indicate that startups make decisions in pandemic situations that are driven by seven myths, pertaining to human, intellectual, and financial resources. The decision on whether to diversify or continue in the same business operation can be divided into four strategic options of the Competency-Industry Relatedness (C-IR) framework: ignore, delay, phase-in, and diversify. Diversification in the same (or different industry) is less risky for startups if they have the skills, as needed, to diversify in related industries. Diversification in related industries helps startups leverage their experiences and learning curves (those associated with existing product lines) to adapt their existing products in new markets, or utilize their technologies to solve new problems via new products. The desired outcome for these startups should be sustainable business growth—to meet sustainability goals by contributing to the society and the economy. Conclusion: The C-IR framework is a strategic guide for startups to make business decisions based on internal factors, rather than myths. Accurately assessing skill diversity and the nature of new industries (or markets) will help startups leverage their existing resources optimally, without the need for (pricey) external funding. This will foster sustained business growth resulting in a nation economic development. Knowledge transfer from the Innovation ecosystem will further strengthen the C-IR framework effectiveness.
