- ItemA green-lean-six sigma model for environmental performance in manufacturing organizations : a study of a developed and developing nation : a thesis presented in partial fulfilment of the requirement for the degree of Doctor of Philosophy in Engineering Management, School of Food and Advanced Technology, Massey University, Auckland, New Zealand(Massey University, 2022) Farrukh, AmnaManufacturing organizations continue to face environmental challenges including greenhouse gas (GHG) emissions, large-scale energy consumption, and solid and liquid waste generation contributing to climate change. While emerging environmental concerns are serious challenges for discrete and process industries in both developed and developing countries, the impact of these issues is more significant for the process industry due to their high energy requirements, GHG emissions, and lack of application of operational strategies. Green-lean-six sigma (GLSS) is recognized as a promising operational and environmental improvement strategy for minimizing waste and conserving resources in manufacturing organizations. However, scant attention has been paid to examining this strategy in addressing the environmental concerns, and in particular, investigating its application between developed and developing nations. The aim of this study is to examine the drivers, enablers, environmental outcomes, and critical success factors (CSFs) of a GLSS strategy in a developed country (New Zealand) and developing country (Pakistan) context in the manufacturing industry. This study draws on the natural resource-based view, institutional theory-based view, and intellectual capital-based view to understand the execution of this strategy and develops a GLSS model for improving the environmental performance in manufacturing organizations. A qualitative research methodology is adopted with semi-structured interviews using the case study approach. In the first phase, a preliminary study is undertaken with lean six sigma and environmental consultants from New Zealand (NZ) and Pakistan (PK). In the second phase, the main study is conducted with senior corporate managers of two large-sized flexible packaging manufacturing companies in both NZ and PK who have implemented the green, lean, and six sigma strategies. This study highlights various internal operational and organizational drivers and external regulatory, market-driven, and society-oriented forces that prompt manufacturing companies to adopt a GLSS strategy. Numerous GLSS enablers for achieving environmental outcomes including waste and emission reduction, resource conservation and recycling, and environmental safety and compliance are revealed. Further, CSFs for the implementation of a GLSS approach comprising the strategic, operational, human resource, and external stakeholder-related elements are presented. By utilizing the results of the preliminary and the main study, a holistic GLSS model is developed for achieving environmental performance in manufacturing organizations, with significant theoretical and practical implications.
- ItemA transformational model to understand the impact of enterprise systems for business benefits : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Information Technology at Massey University, Albany, New Zealand(Massey University, 2010) Mathrani, SanjayOver the years many organizations have implemented an enterprise system (ES), also called enterprise resource planning (ERP) system, to streamline the flow of information and improve organizational effectiveness to produce business benefits which justify the ES investment. The effectiveness of these systems to achieve benefits is an area being proactively researched by both professionals and academia. However, most of these studies focus on ‘what ESs do’ rather than ‘how ESs do it’. The purpose of this study is to better understand how organizations derive benefits from utilization of an ES and its data. This study utilizes a transformational model of how ES data are transformed into knowledge and results to evaluate the impact of ES information on organizational functions and processes and how this can lead to business benefits. The linkage between expected outcomes, utilization of ES data in decision-making processes, and realized or unrealized benefits provides the reason for this study. Findings reveal that the key benefits commercial firms seek from an ES include improving information flow and visibility, integration and automation of functions, cost reductions by reducing inventory, and achieving process efficiencies for both internal and external operations. The various tools and methods businesses use for transforming ES data into knowledge include the use of data warehouses and business intelligence modules that assist in extraction and manipulation of data, and reporting on particular data objects. Web portals are actively utilized to collaborate between stakeholders and access real-time information. Business tools such as KPI reporting, balanced scorecards and dashboards are used to track progress towards realizing benefits and establishing analytical decision making. Findings emphasize that benefit realization from an ES implementation is a holistic process that not only includes the essential data and technology factors, but also includes other factors such as business strategy deployment, people and process management, and skills and competency development. Findings reveal that business organizations generally lack in producing value assessments that often lead to weak business cases and insufficient benefit models which cannot be used for benefit tracking. However, these organizations are now realizing that it is not enough to put in an ES and expect an automatic improvement. Organizations are now establishing analytical and knowledge-leveraging processes to optimize and realize business value from their ES investment.
