Teaching Lean Six Sigma within A Supply Chain Context: The Airplane Supply Chain Simulation

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.  相似文献   

Enacted Goal Attention in Family Conversations about End-of-life Health Decisions     

Allison M. Scott  John P. Caughlin 《Communication monographs》2014,81(3):261-284

Most extant research on end-of-life communication in families has been based on the assumption that more communication is better communication. We used a multiple goals theoretical perspective to demonstrate that the quality of communication about end-of-life decisions matters. Members of 121 older parent/adult child dyads (N = 242) engaged in an elicited conversation about end-of-life health choices and reported their assessments of the conversation. Using multilevel linear modeling, we found that outside ratings of a person's communication quality (i.e., attention to task, identity, and relational goals) as well as outside ratings of the partner's communication quality were positively associated with the person's reported conversational satisfaction and hopefulness and negatively associated with the person's hurt feelings and relational distancing.  相似文献

Grand Innovation Prizes: A theoretical,normative, and empirical evaluation     

Fiona Murray  Scott Stern  Georgina Campbell  Alan MacCormack 《Research Policy》2012,41(10):1779-1792

This paper provides a systematic examination of the use of a Grand Innovation Prize (GIP) in action – the Progressive Automotive Insurance X PRIZE – a $10 million prize for a highly efficient vehicle. Following a mechanism design approach we define three key dimensions for GIP evaluation: objectives, design, and performance, where prize design includes ex ante specifications, ex ante incentives, qualification rules, and award governance. Within this framework we compare observations of GIPs from three domains – empirical reality, theory, and policy – to better understand their function as an incentive mechanism for encouraging new solutions to large-scale social challenges. Combining data from direct observation, personal interviews, and surveys, together with analysis of extant theory and policy documents on GIPs, our results highlight three points of divergence: first, over the complexity of defining prize specifications; secondly, over the nature and role of incentives, particularly patents; thirdly, the overlooked challenges associated with prize governance. Our approach identifies a clear roadmap for future theory and policy around GIPs.  相似文献   

Noise-enhanced dynamic single leg balance in subjects with functional ankle instability     

Scott Ross  Brent Arnold 《运动与健康科学(英文)》2012,1(2):102-106

BackgroundStochastic resonance stimulation (SRS) transmits subsensory electrical Gaussian white noise into the body to enhance sensorimotor function. This therapy has improved static single leg balance in subjects with functional ankle instability. However, the effect of this stimulation on dynamic single leg balance is not known. Improvements in dynamic single leg balance with SRS may have implications for enhancing functional rehabilitation for ankle instability. Thus, the purpose of this study was to determine the effects of SRS on dynamic single leg balance in subjects with functional ankle instability.MethodsThis study was an experimental research design and data were collected in a sports medicine research laboratory. Twelve subjects with functional ankle instability (69 ± 15 kg; 173 ± 10 cm; 21 ± 2 years) reported a history of ankle sprains and instability at the ankle with physical activity. A single leg jump-landing test was used to assess dynamic balance. Subjects were required to jump between 50% and 55% of the maximal vertical jump height, land on a single leg atop a force plate, and stabilize as quickly as possible. Jump-landing tests were performed with and without SRS. Three trials were performed for each treatment condition (SRS and control). A randomized block design was used to determine test order. Anterior/posterior and medial/lateral time-to-stabilization were computed to assess dynamic balance. Lesser time indicated better stability. One-tailed paired samples t tests were used for analysis (α ≤ 0.05).ResultsSRS improved anterior/posterior time-to-stabilization (stochastic resonance = 1.32 ± 0.31 s, control = 1.74 ± 0.80 s, p = 0.03), but did not enhance medial/lateral time-to-stabilization (stochastic resonance = 1.95 ± 0.40 s, control = 1.92 ± 0.48 s, p = 0.07).ConclusionClinicians might use SRS to facilitate balance improvements with sagittal plane dynamic single leg balance exercises that patients may not be able to perform otherwise.  相似文献
