A Case Study on Lean Manufacturing Strategies

Over the past several years U.S. EPA’s Office of Reinvention has been involved in a number of “regulatory responsiveness” initiatives. These include the Common Sense Initiative, Project XL, and Pollution Prevention in Permitting Program (P4). In working with a variety of businesses in the context of these initiatives, certain project participants noted that corporate manufacturing strategies and initiatives often produced substantial resource productivity enhancements.

At the same time, the responsiveness and continuous improvement aspects of these strategies were driving on-going modifications to operating equipment and operating parameters that could be subject to new environmental permitting and/or modifications to existing permits. This meant that desired changes could be subject to regulatory bottlenecks (in terms of time, uncertainty, and administrative costs) that could constrain responsiveness, continuous improvement, and, ultimately resource productivity gains.

Case Study on Extreme Programming in a University Environment

Abstract: Extreme Programming (XP) is a new and controversial sojiware process for small teams. A practical training course at the university of Karlsruhe led to the following observations about the key practices of Xl?

First, it is unclear how to reap the potential benejits of pair programming, although pair programming produces high quality code. Second, designing in small increments appears problematic but ensures rapid feedback about the code. Third, while automated testing is helpful, writing test cases before coding is a challenge. And last, it is dificult to implement XP without coaching. This paper also provides some guidelines for those starting out with XR. Click here to read more…
