原则是行动指南，是 LPS 的核心，被正确理解，与其面向社会规划系统的方向一致，作为要执行的功能的复杂性和在其执行中要遵循的原则。原则源自对相关现实性质的预设，并发明了实施原则的方法。系统地改进方法，包括借用和适应其他应用程序，例如敏捷方法。一个方法是“精益”的，如果它适合于执行 LPS 功能的目的，则属于 LPS，无论该方法起源于何处。

Principles are guides to action and are central in the LPS, which is properly understood, consistent with its orientation toward the social system of planning, as the complex of functions to be performed and principles to follow in their performance. Principles are derived from presuppositions about the nature of the relevant reality, and methods are invented to implement the principles. Methods are improved systematically, including by borrowing and adapting from other applications, e.g. agile methods. A method is ‘Lean’ and belongs to the LPS if it is fit for purpose in performing LPS functions, regardless where the method originated.<br>

原则是行动的指南，是LPS的核心，正确理解LPS，符合其面向社会规划系统的方向，是要执行的复杂功能和执行中要遵循的原则。原则源于对相关现实的性质的预设，而方法是为了实现这些原则而发明的。系统地改进方法，包括从其他应用程序中借用和改编，例如敏捷方法。一个方法是“精益”的，如果它适合执行LPS功能，则属于LPS，无论该方法源自何处。
