Hello,
Are you looking for functional or technical issues? At the highest level, the biggest issues I've seen with OTM integration that dramatically affect the project timelines are:
- Complete the gap analysis ASAP (technical and functional) - so that you'll know the issues you need to resolve and will have a good lay of the landscape early in the project.
- Install and configure your integration middleware as soon as possible, so that it can be proven before your OTM go-live.
- Ensure constant and efficient communication between your functional superusers and the team developing the integration. Critical for ensuring that all needs are appropriately addressed.
With a more specific post, you may be able to gather more responses from the community.
Thanks,
Chris
