My research develops innovative statistical methods for process improvement and understanding. More specifically, I propose to continue my work in the following three areas among others: Statistical Engineering, Measurement System Assessment, and Process Monitoring and Understanding. The results of my research which tackle real world problems have the potential to greatly influence industrial practice. Specific goals include improving the definition and widening the application of Statistical Engineering and developing a field failure prediction methodology applicable at Research in Motion, based on data from a variety of sources, including manufacturing, final test, warrant and customer usage. In addition, I plan to develop new and better plans and analyses for the assessment and comparison of measurement systems. Here a specific focus will be on relaxing questionable assumptions and tackling non-standard measurement characteristics, such as, counts, bounded data and multivariate data. A third research theme focuses on developing models and methods for monitoring processes when the output characteristics are not directly comparable and to better understand their performance. One specific project involves developing a method for monitoring the surgical learning curve. I also propose to re-examine the fundamental concepts and terminology of Statistical Process Control (SPC). The current environment has little coherence and many contradictions that result in confusion. Developing a consistent and concise set of definitions will improve SPC understanding and hopefully successful usage.

我的研究为流程改进和理解开发了创新的统计方法。更具体地说，我建议继续在以下三个领域开展工作：统计工程、测量系统评估和过程监控与理解。我的研究结果解决了现实世界的问题，有可能对工业实践产生重大影响。具体目标包括改进统计工程的定义和扩大其应用范围，并根据制造、最终测试、授权和客户使用等各种来源的数据，开发适用于Research in Motion的现场故障预测方法。此外，我计划制定新的更好的计划和分析，以评估和比较测量系统。在这里，一个具体的重点将是放松有问题的假设和处理非标准测量特征，如计数、有界数据和多元数据。第三个研究主题侧重于制定模型和方法，以便在产出特性不能直接比较时监测过程，并更好地了解其表现。一个具体的项目涉及开发一种监测外科学习曲线的方法。我还建议重新审查统计过程控制(SPC)的基本概念和术语。目前的环境几乎没有连贯性，许多矛盾导致混乱。制定一套一致和简明的定义将提高对SPC的理解，并有望成功地使用。
