This is a post by Cat McClintock on PTC site.
A traditional product lifecycle management (PLM) system provides a secure central repository for all of a company’s product designs and associated data. It also manages the flow of that data by automating common processes, like engineering change orders. In the most sophisticated settings, you’ll even find it completely integrated into a company’s ERP system as well.
Traditional PLM systems are complex organisms that require a lot of planning, investment, and IT resources to do correctly.
So, when PTC announced earlier this year that you could now use its professional PLM technology via the cloud, some people were pretty excited about the implications. On the cloud, your PLM solution is delivered as a service with no software residing on your computer. In software circles, we call that Software as a Service, or SaaS. It means that someone else worries about deploying the technology, upgrades, storage space, availability, security, etc.
