- Siebel data is highly structured - it's a relational database after all
- InfoPath is based on semi-structured data - it's document focused
- Siebel releases take months
- InfoPath forms can be updated and released the same day
Siebel on the other hand is a great work package management tool in directing and assigning work to teams and users. It manages the life cycle of work. Stitching the two tools together is not so easy and requires a bit of thinking for how things need to work together.
