Blogger over at Systematic Viewpoints has been writing about PeopleSoft portals and his implementation experiences lately. Of particular interest is his/er organization's struggle with the HR portal versus the enterprise portal. If you're on common platforms (PS, SAP, PT) then integration isn't so bad. Even if they are not on the same platform, I'm not sure the enterprise portal really needs to interact with the HR portal. The content is sufficiently different and any data exchanges should be achievable through the data warehouse.
Well, I'll looking forward to seeing how his/er tools and portal implementations go. I'm especially interested to see what Oracle offers his/er organization in the upcoming months.
