The proposed effort would entail conducting a number of pilot projects that can serve as test-beds, providing not only a learning laboratory but also generating tangible benefits. The resulting product – structured methodology, best practices, and tools and techniques, training and educational materials – can be used by many organizations to pursue collaborative action, to validate their existing processes, and to deploy as needed in particular situations. 2006-06-15T00:00:00Z https://hdl.handle.net/1721.1/146754 Lean Supply Chain Now: Proposed Concept Demonstration Initiative – An Activity of the Lean Aerospace Initiative Supplier Networks Working Group Bozdogan, Kirkor The aerospace supplier base is characterized by complex interfaces that represent a significant source of waste, delay and defects.

The paper is addressed at a general business, government and academic audience interested in enterprise transformation, with particular focus on the role of the Lean Advancement Initiative as a unique industry-government-academic partnership dedicated to the creation of a learning community for enterprise transformation through holistic enterprise systems thinking. 2008-03-31T00:00:00Z https://hdl.handle.net/1721.1/82088 LAI Whitepaper Series: “Lean Product Development for Practitioners”: Program Management for Large Scale Engineering Programs Oehmen, Josef; Rebentisch, Eric; Kinscher, Kristian The whitepaper begins by introducing the challenges of programs in section 4, proceeds to define program management in section 5 and then gives an overview of existing program management frameworks in section 6. In section 7, we introduce a new program management framework that is tailored towards describing the early program management phases – up to the start of production. This framework is used in section 8 to summarize the relevant LAI research. 2012-09-11T00:00:00Z https://hdl.handle.net/1721.1/82086 Towards an Integration of the Lean Enterprise System, Total Quality Management, Six Sigma and Related Enterprise Process Improvement Methods Bozdogan, Kirkor The lean enterprise system, total quality management, six sigma, theory of constraints, agile manufacturing, and business process reengineering have been introduced as universally applicable best methods to improve the performance of enterprise operations through continuous process improvement and systemic planned enterprise change. Generally speaking, they represent practice-based, rather than theory-grounded, methods with common roots in manufacturing. Most of the literature on them is descriptive and prescriptive, aimed largely at a practitioner audience. Despite certain differences among them, they potentially complement each other in important ways. The lean enterprise system, total quality management and six sigma, in particular, are tightly interconnected as highly complementary approaches and can be brought together to define a first-approximation “core” integrated management system, with the lean enterprise system serving as the central organizing framework. Specific elements of the other approaches can be selectively incorporated into the “core” enterprise system to enrich its effectiveness. Concrete theoretical and computational developments in the future through an interdisciplinary research agenda centered on the design and development of networked enterprises as complex adaptive socio-technical systems, as well as the creation of a readily accessible observatory of evidence-based management practices, would represent important steps forward. 2010-08-05T00:00:00Z https://hdl.handle.net/1721.1/82085 Evolution of the Lean Enterprise System: A Critical Synthesis and Agenda for the Future Bozdogan, Kirkor Many aerospace enterprises and other organizations have adopted a variety of management approaches to achieve continuous process improvement, enterprise change and transformation, such as the lean enterprise system, total quality management (TQM), theory of constraints (TOC), agile manufacturing, and business process reengineering (BPR). Among them, the lean enterprise system, with its origins in the Toyota Production System (TPS), comes closest to providing a holistic view of enterprises as complex socio-technical systems embodying a mutually supportive set of precepts and practices driving enterprise operations at all levels (i.e., strategic, tactical, operational) and throughout the enterprise value stream encompassing both upstream supplier networks and downstream customerfocused activities. Lean enterprise principles and practices have evolved over many decades through a process of experimentation, learning and adaptation. A distinction is made between the basic lean enterprise system (BLES), capturing salient developments over the period between the late 1940s and mid-1990s, and the contemporary lean enterprise system (CLES), capturing major conceptual and implementation-related extensions of the basic model since the mid-1990s. The lean enterprise system, as a viable framework for explaining the structure and dynamics of modern networked enterprises, for managing them, and for improving their performance through either continuous process improvement or planned systemic change and transformation, remains a work-in-progress. 2010-07-31T00:00:00Z https://hdl.handle.net/1721.1/82084 LAI Paper Series: “Lean Product Development for Practitioners”: Waste in Lean Product Development Oehmen, Josef; Rebentisch, Eric Reading this whitepaper provides a concise overview of the most important waste drivers in product development, that is, the most common project deficiencies that lead to cost and schedule overrun, as well as to performance issues. It will enable those involved in process improvement initiatives to include specific lean-related factors into their process analysis. It provides both managers and engineers with a common language and concepts to enhance the efficiency of their product development projects. 2010-07-10T00:00:00Z https://hdl.handle.net/1721.1/82083 LAI Paper Series: “Lean Product Development for Practitioners”: Risk Management in Lean PD Oehmen, Josef; Rebentisch, Eric The two core challenges of risk management are finding the optimum balance a) between the cost of carrying risks vs. the cost of mitigating risks and b) between a risk that is taken with a certain development project and the return that is expected from the project. A complete absence of risk management will minimize the cost of risk mitigation measures – no backup development capacity, no review meetings, no quality control incur no direct cost. However, the project becomes very vulnerable towards uncertainties: If a development task turns out to be more complex than previously anticipated and no backup capacity can be brought to bear, the entire project might be delayed and cost incurred through idle capacities, penalty payments towards the customer for delays or opportunity cost for lost customers and market share. The same may happen for less-than-perfect coordination between different engineers and departments, or erroneous designs that would otherwise have been uncovered in review meetings or quality checks. On the other hand, excess backup capacity, reviews and quality controls bind more resources and cost more money than they save. Good risk management helps to strike the right balance between minimizing risk and the cost of doing so. After minimizing the overall risk as much as is sensible, the question remains what the right level of risk is that is still acceptable for a project to be attractive. While the goal for every single project is to minimize its overall risk, projects are in general exposed to different levels of uncertainty: Some might involve more innovative technologies or technologies that the company is not familiar with; some might address new markets where the exact customer requirements are unclear; and others might just be a lot bigger than usual and therefore have a much more significant impact if they fail. The goal is to find projects that have the right balance of risk and return, as would be the case with any other investments (e.g. a portfolio of stocks and bonds). 2010-03-31T00:00:00Z https://hdl.handle.net/1721.1/82082 Knowledge Ingtegration in Large-Scale Organizations and Networks - Conceptual Overview and Operational Definition Haddad, Marc; Bozdogan, Kirkor Knowledge integration is an emerging discipline in organizational science where the central proposition is that the increasing complexity of products and services being developed and delivered, means that the knowledge required for production is increasingly specialized, varied (multi-disciplinary) and distributed across the organization’s internal boundaries, and as a result there is a need for organizations to continuously gather their knowledge resources in order to maintain their ability to innovate, and to sustain their competitive position in the market. In addition, the increasing scale and scope of organizational arrangements, such as multinational partnerships or multi-tiered prime-supplier arrangements commonly encountered in the aerospace, automotive and other complex product development industries, also give rise to environments of dispersed knowledge resources, thus necessitating the subsequent integration of this knowledge across external boundaries spanning large-scale organizational networks. Knowledge integration in this context is done through a process of transferring knowledge from multiple sources in the organizational network to where it is needed, combining it with existing knowledge, before it can be applied to accomplish complex tasks and to solve major problems. The primary purpose of this paper is to define the powerful concept of knowledge integration in large-scale organizational networks using an extensive review of the pertinent literature on knowledge in organizations. An operational definition for knowledge integration is also proposed, followed by a systematic identification and classification of the different strategies, practices, channels and mechanisms for integrating different types of knowledge across a multitude of organizational boundaries and environments. 2009-12-30T00:00:00Z
