These documents provide a high-level guidance to those considering customizing Windchill ESI and Windchill Integration for MES. They are not intended to be prescriptive or extensive. Customization should not be undertaken lightly. Customization can have a major impact on technical support, maintenance, and future upgrades. The costs and benefits of a customization should be carefully analyzed with an experienced systems integrator prior to moving forward. Also, you should discuss the product roadmap with your PTC representative to determine if future product releases will include the desired functionality. Customizing must be viewed from an end-to-end system perspective. Windchill ESI and Windchill Integration for MES consist of many components organized in a layered architecture. Customizations generally cannot be confined to a single component or module, due to the many interrelationships and dependencies between components. In other words, you should carefully consider the downstream effects of any modifications to the standard configuration.
