    The purpose of this study is to evaluate critical success factors (CSFs) for the implementation of an enterprise resource planning (ERP) system from a user perspective. Users play a vital role when implementing an ERP system, but their perspective has been neglected in the literature. A better understanding of their perspective promises to contribute to the design of more effective ERP systems, its implementation, and management. In order to identify the user perspective, a survey was conducted within three organizations from Pakistan that have recently implemented an ERP system. The questionnaire was developed based on thirteen CSFs deduced from literature. Based on each CSF’s level of importance, they are ranked in order of importance and divided into three groups: most important, important and not important. Findings reveal that users of the three organizations in Pakistan believe that the implementing organization should prioritize the following four CSFs when implementing an ERP system: education and training, strategic decision-making, communication, and business process alignment.

    The contemporary shipping industry is a high-risk business activity that is highly regulated by the International Maritime Organization (IMO). Changes in IMO regulations are often triggered by major incidents that bring safety at sea into public view. They may address ship instruments, operation, cargo, crew, environment, security and safety, and can generate higher Capital Expenses (CAPEX) and Operational Expenses (OPEX) for shipping businesses. Oil tanker owners are key stakeholders in the shipping industry and are most exposed to the risk of higher on-cost expenses both for CAPEX and OPEX. Between 2006 and 2019, regulations regarding oil tankers were changed six to seven times per year. This paper assesses the financial impact of changes in major international maritime regulations, primarily, the International Convention of Safety of Life at Sea (SOLAS), MARPOL, and STCW. The methodology involves using a risk matrix from a specific company and combining it with system dynamics to forecast the dynamic effect of such changes on the oil tanker market. The result shows that changes in regulations can have a catastrophic impact on the sustainability of the oil tanker business.

  3. Strategies for Managing Excess and Dead Inventories: A Case Study of Spare Parts Inventories in the Elevator Equipment Industry
    • Oguji Nnamdi
    Spare parts organizations of elevator original equipment manufacturers (OEM) face enormous challenges on how to manage their excess and dead inventory due to the life-cycle of the equipment. On one hand, the long life-cycle of equipment’s requires that organizations ensure the provision and availability of the spares until equipment termination / retirement. On the other hand, these organizations need to control their inventory carrying cost, inventory write-offs and ensure that only needed spare parts are available for their customers. This study explores operations and inventory strategies for reducing and controlling excess inventory. Through a combination of literature review, root cause analysis and the implementation of these strategies in a case company, a managerial tool-box for managing and controlling excess inventory was developed. Root causes of excess inventory were shown to be due to data errors in inventory planning parameters, inappropriate demand forecasting methods, lack of ownership, lack of part life-cycle management and part life-cycle pricing as well as internal practices within the organizations. The paper proposes managerial tool-box that includes both Strategic (ownership and key performance indicators, strategic policy on reverse logistics, customer buy-backs, large purchase volumes for sourcing savings, leveraging Big Data and Analytics); Reactive (lateral transshipment, scraping & disposal of excess inventory, sales discounts, spare parts dismantling into sub spare parts) and Proactive (Croston/SBA forecasting, exception management for data errors, tool/algorithm for new spare parts forecasting, part replacement control measures, forecasting sudden decrease in demand and part life-cycle pricing) measures on how excess inventory can be controlled and reduced.

  4. Personal Relationships and Higher Agency Costs: Study of Buyers and Suppliers in Australian Manufacturing and Service Sector
    • Atif Saleem Butt
    Personal relationships (i.e. friendships) have been the subject of much research in the business discipline, with the majority of literature focusing on how personal relationships yield positive firm-level outcomes. However, personal relationships are not without drawbacks and may lead to negative outcomes for the firms involved. Despite this, the current body of knowledge on this issue is relatively fragmented. This paper addresses this important gap in the literature. For exploratory purposes, the study is qualitative in nature. Based on a grounded theory approach, a model is developed describing how personal relationships embedded within inter-firm relationships lead to negative outcomes for the firms. Overall, 16 in-depth interviews with seniormanagers of buying and supplying firms were undertaken. Results from this study exhibit that managers engage in exploitation of personal relationships by demanding higher sales commission, higher bonuses and higher salaries from their respective firms, leading to higher agency costs. Firms can use these finding to understand explicitly what types of negative consequences personal relationships yield. Further, this study presents to firms specific actions that managers of buying and supplying firms engage in, when a personal relationship is present between them in the supply chain Finally, this paper concludes by providing several constructive guidelines to firms on managing personal relationships within inter-firm relationships in order to mitigate its negative firm-level consequences.

    Due to technological boom, the quantity of electronic goods is significantly growing. After their useful life, they become e-waste which has considerable impacts on the environment and society. To mitigate the issue, the reverse supply chain (RSC) has been investigated to reuse components or recycle raw materials contained in e-waste. The total cost of RSC operation is one of the vital issues which has been receiving more attention from both industry and academia. The existing research concentrates on minimizing the overall cost of the system like transportation, operating, disposal and fixed costs. However, risks normally involved during the transportation of e-waste in RSC network has not been addressed. These risks might involve collection delays, breakdown of trucks, accidents and the variation of hazardous materials which can result in unexpected disruptions and significantly higher cost. Currently, there is no research incorporating transportation risk in RSC operation. This paper is aimed to develop a mathematical model for the total cost minimization of an e-waste RSC system with consideration of transportation risk. A mixed integer linear programming is applied in the proposed model and solved by an optimization software. To illustrate the applicability of the proposed model, a numerical example is also examined. The results of this paper can decide the optimal locations for treatment centers and the flow of used products or components delivered within an e-waste RSC network. This result can support managers to design an e-waste RSC network whilst transportation risk factors are considered.
