PropelPLM is a wonderfully flexible and powerful system with the power residing behind the curtain and not visible to end users. If you have any thoughts of implementing PropelPLM it is likely you will also have to deal with data migrations, customizations and configuration tweaks. Propel makes this comparatively easy but the framework may be a new experience for you. This is especially true if you are coming from a relational database and/or traditional application background.
Propel is hosted on the Salesforce.com platform. This imbues PropelPLM with tremendous tools and opportunities. To be prepared to best take advantage of all that PropelPLM has to offer, you should be comfortably versed in Salesforce.com methods, terminology and opportunities.
