What is the difference between windchill and team center?

I would agree with many of the prior answers.  Talent and devotion both have a role to play in success as do many other factors including persistence, adaptability, team, and luck

Teamcenter is developed by SIEMENS and so it is tightly integrated with UG-NX. Windchill is developed by PTC and is tightly integrated with PRO-E.

Teamcenter provide neutral format as JT (Jupiter Translator) but windchill does not support JT.

In totality both are meant for Product Life Cycle Management.
