Project Life Cycle Considerations
Before planning aWindchill ESI installation, you also need to take into account factors that define the life cycle of a project. The following provides a check list of some of these factors and what you need to consider and have in place to successfully use Windchill ESI.
As mentioned earlier, you need to first consider and define your requirements. Once you have listed your requirements, you need to evaluate these requirements against the features offered by Windchill ESI. Performing a gap analysis in the following three areas would help you determine if there are any differences between theWindchill ESI out-of-the-box features and your requirements.
