PurposeThis paper aims to create a new decision-making procedure that uses “Lot-by-Lot Acceptance Sampling Plan by Attributes” methodology in the production processes when any production interruption is observed in tobacco industry, which is a significant example of batch production.Design/methodology/approachBased on the fish bone diagram, the reasons of the production interruptions are categorized, then Lot-by-Lot Acceptance Sampling Plan by Attributes is studied to overcome the reasons of the production interruptions. Furthermore, managerial aspects of decision making are not ignored and hence, acceptance sampling models are determined by an Analytical Hierarchy Process (AHP) among the alternative acceptance sampling models.FindingsA three-phased acceptance sampling model is generated for determination of the reasons of production interruptions. Hence, the necessary actions are provided according to the results of the proposed acceptance sampling model. Initially, 729 alternative acceptance sampling models are found and 38 of them are chosen by relaxation. Then, five acceptance sampling models are determined by AHP.Practical implicationsThe current experience dependent decision mechanism is suggested to be replaced by the proposed acceptance sampling model which is based on both statistical and managerial decision-making procedure.Originality/valueAcceptance sampling plans are considered as a decision-making procedure for various cases in production processes. However, to the best of our knowledge Lot-by-Lot Acceptance Sampling Plan by Attributes has not been considered as a decision-making procedure for batch production when any production interruption is investigated.
Subject area Forecasting. Study level/applicability The case is intended for Postgraduate level management students. Case overview The purpose of this case study is to explain various forecasting techniques, their applicability and the importance of forecasting to the students. This case also explains the management situations where the application of one technique may not be sufficient, thereby explaining the importance of simultaneous usage of qualitative and quantitative techniques for making crucial decisions. The case is focused on the district of Etah of the state of Uttar Pradesh in India. The real-life situation of elections in this district of an Indian state has been taken to explain the critical nature of forecasting accuracy in a management situation where the manager has only one chance to execute his project. Discussion in this case is limited to explaining various techniques available for forecasting and their applications and does not provide a solution to a management problem. Expected learning outcomes The students are expected to understand various forecasting methods and the managerial situations where these can be applied. The case also explains situations where it becomes extremely important to have fairly accurate estimates of future requirements and the application of one technique may not be sufficient, thereby explaining the importance of simultaneous usage of qualitative and quantitative techniques for making crucial decisions.

Structured abstract Subject area information and communication technology (ICT) for development. Study level/applicability Master of Business Administration Program’s Management Information Systems courses. Or introductory courses in Masters in ICT for Development. Case overview The paper aims to highlight the endeavour of public distribution system (PDS), a food security scheme for under-privileged people in India, towards excellence, using ICT in the state of Chhattisgarh. It presents two important roles of ICT: one, as a system improvement tool, through supply chain integration (in Phase 1) and, the other, as tool for empowerment, by providing choices through computerized online real-time electronic (CORE) PDS (in Phase 2). CORE PDS was intended to provide choices of retail outlets to poor beneficiaries for collecting their food entitlement, breaking the retail outlet’s monopoly. The project was successfully implemented in some urban areas of Chhattisgarh, providing motivation for its mass scale roll-out. But, the contextual differences between rural and urban settings were raising questions on the ultimate value expected to be delivered by the project in rural areas. Expected learning outcomes Two major learning outcomes of the case: students will appreciate the multi-faceted role of ICT in improving the performance of a system meant for a financially poor section of the society; students will understand the role of contextual settings in a developing economy in the endeavour of ICT projects for societal development.
