只有PLM可以最大限度地实现跨越时空、地域和供应链的信息集成，在产品全生命周期内，充分利用分布在ERP、CRM、SCM等系统中的产品数据和企业智力资产。因此，PLM系统的价值取决于在企业内能否与ERP、SCM、CRM来集成使用，组成PLM生态系统。由于企业各自的特点和问题不同，在实施PLM系统时也不必要求四个系统全部一齐上马，合理的方式是针对企业具体需求而为其提供系统组合的入门方案，“统一规划，按需建设，重点受益”。
PLM在应用过程中的建立方法一：以企业资源规划为出发点组成PLM系统
广为使用的PLM应用思路之一：例如在规定的时间内制造某种设备，MRP系统从PDM系统中提取材料清单（BOM），来决定什么样的装配必须自行创建，什么样的材料必须外购。这样比较好地解决了工程BOM和制造BOM的沟通问题。
(2)人力资源与项目管理（HRProjectManagement）
项目管理系统在做日常工作的协调与管理时，需要调用企业内可用的资源（例如人员和时效性等）数据。
(3)采购与项目管理（Purchasing ProjectManagement）
企业建造某种设备时，项目团队通常需要购买原材料，需要生成采购订单的能力。这个订单可以与财务预算联系起来。
⑷财务与项目管理（Financials ProgramManagement）
项目管理是监测预算并实现跨项目预测的一种软件工具。它提取每一个项目的财务信息并检查：当前成本是否与预期的成本相符，时间表是否与所有的项目进度相符；
⑸生产管理与工程（ProductionManagement Engineering）
为了有效地沟通从工程研发到车间工作面的工程变更指令（ECO），产品数据需要在制造和PMD系统（经由CAD系统）之间流动起来。这将有助于减少不合格的零件的生产。

What are the methods of PLM establishment in the application process?
Only PLM can maximize the integration of information across time, geography and supply chain, and make full use of product data and enterprise intellectual assets distributed in ERP, CRM, SCM and other systems throughout the product life cycle. Therefore, the value of a PLM system depends on whether it can be integrated with ERP, SCM, and CRM within the enterprise to form a PLM ecosystem. Due to the different characteristics and problems of each enterprise, it is not necessary to require all four systems to be mounted together when implementing PLM systems, and the reasonable way is to provide an entry-level solution of system combination for the specific needs of enterprises, “unified planning, on-demand construction, and focus on benefits”.

PLM system is formed based on enterprise resource planning
(1) Material Requirements Planning and Product Data Management (MRPPDM)
One of the most widely used PLM application ideas: For example, to build a certain device within a specified time, the MRP system extracts a bill of materials (BOM) from the PDM system to determine what assembly must be created and what materials must be purchased. This better solves the problem of communication between engineering BOM and manufacturing BOM. Digital transformation network szhzxw.cn
(2) Human Resources and ProjectManagement
When the project management system does the coordination and management of daily work, it needs to call the available resources (such as personnel and timeliness) data in the enterprise.
(3) Purchasing ProjectManagement
When a company builds a piece of equipment, the project team usually needs to buy raw materials and needs the ability to generate purchase orders. This order can be linked to the financial budget. Digital transformation network szhzxw.cn
⑷ Financials ProgramManagement
Project management is a software tool for monitoring budgets and making predictions across projects. It extracts financial information for each project and checks whether current costs are in line with expected costs, and whether timelines are in line with all project schedules; Digital transformation network szhzxw.cn
(5) ProductionManagement Engineering
In order to effectively communicate engineering change orders (ECO) from engineering development to the shop floor, product data needs to flow between manufacturing and PMD systems (via CAD systems). This will help reduce the production of substandard parts. Digital transformation network szhzxw.cn
