PLM与PDM有什么区别？PLM完全包含了PDM的全部内容，PDM功能是PLM中的一个子集。但是PLM又强调了对产品生命周期内跨越供应链的所有信息进行管理和利用的概念，这是与PDM的本质区别。
由于PLM与PDM的渊源关系，实际上几乎没有一个以“全新”面貌出现的PLM厂商。大多数PLM厂商来自PDM厂商。有一些原PDM厂商已经开发了成体系的PLM解决方案，成功地实现了向PLM厂商的转化，如EDS、IBM。当然，也有ERP厂商的加入，如SAP，已经提出了自己的基于ERP立场的PLM解决方案，试图在这个广大的市场上来分一勺羹；还有一些CAD或工程软件厂商也在正在做这样的努力。需要指出的是，有一些原来本是PDM/CAD的厂商，并没有推出实际的PLM产品，而只是改了个名字就自称为PLM解决方案厂商，顺道搭车卖一些低端的PDM/CAD产品。这样一些鱼目混珠的动作给市场和广大客户都造成了很多的困惑。PLM，并不是一种简单的“系统集成”——例如，把一个PDM，两个CAD，再来一个数字化装配，加之连接上某个ERP或是SCM系统，辅之以Web技术，就是“PLM”系统了。
这样做，只是实现了一种技术的堆积和继承，只是完成了任务和过程自动化这样的功能，没有体现出PLM真正的思想和内涵。尽管以上的技术是需要的，但是对于实施PLM战略是不充分的。首先要理解到，由于PLM策略是完全从事于不同的商业使命，因而它需要更复杂的系统体系结构。PLM技术的选择和实施必须以这样的方式来做，构建一个面向更广泛的商业使命的生命周期财富管理系统来组成。技术的采用必须根据这个高层次的使命的原则来选择，而不是以完成任务和过程自动化这样传统的历史使命来选择。

What is the difference between PLM and PDM?
What’s the difference? PLM contains all the content of PDM, and PDM function is a subset of PLM. However, PLM also emphasizes the concept of managing and utilizing all information across the supply chain during the product life cycle, which is an essential difference from PDM.

Due to the relationship between PLM and PDM, there is virtually no “new” appearance of PLM vendors. Most PLM vendors come from PDM vendors. Some original PDM vendors have developed systematic PLM solutions and successfully implemented the transformation to PLM vendors. Such as EDS and IBM. Of course, there are also ERP vendors to join, such as SAP, has put forward their own ERP standpoint of PLM solutions, trying to get a share of this vast market; Other CAD or engineering software vendors are doing the same.
It should be pointed out that some of the original PDM/CAD manufacturers did not launch actual PLM products. But just changed their name to call themselves PLM solution manufacturers, and sold some low-end PDM/CAD products along the way. Such actions have caused a lot of confusion to the market and the majority of customers. PLM is not a simple “system integration” – for example, a PDM, two CAD, and then a digital assembly, coupled with a connection to an ERP or SCM system, supplemented by Web technology, is a “PLM” system.
In doing so, it only realizes the accumulation and inheritance of a technology, and only completes the function of task and process automation, which does not reflect the true idea and connotation of PLM.
While the above techniques are needed, they are not sufficient to implement a PLM strategy. The first thing to understand is that because PLM strategy is completely engaged in a different business mission,. It requires a more complex system architecture. The selection and implementation of PLM technology must be done in such a way as to build a life-cycle wealth management system for the broader business mission. Technology adoption must be selected according to the principles of this high-level mission. Rather than the traditional historical mission of accomplishing tasks and automating processes.
