The solution itself is very heavy. 

If Oracle can provide a better cloud version, they could provide a cloud dated version that can be deployed on a microservice.

There needs to be a way to move things in and out of the cloud, and the solution shouldn't just run on an Oracle cloud either. they need to also ensure users can use any cloud provider, including AWS, Azure, Google, etc. 

The most important thing they need to do is offer cloud-native support. A lot of benefits that come with the cloud-native implementation can be realized.

The solution needs to auto-scale and offer horizontal scaling.

Oracle is working very, very hard in moving such solutions to a software as a service, like other CRMs. We hope it will be fully SaaS in the future.

It is difficult to set up.

It's hard to get to the level of support you need. 

Siebel has been on the market for the last two decades. It used to be the top solution, but nowadays, you have cloud-based CRMs, so it's a little outdated.

The backend performance of Siebel could be improved as it is often slow. In addition, the Open UI is not that responsive. If we send out a call to a server, click any buttons or any drill-down links, and then click on that thread itself, it gets stuck and the system freezes. 

Secondly, the customization capabilities available to users could be reduced. Over time, technical debt increases and the system starts to slow down due to all the customizations and this leads to user complaints. 

Finally, the cost of this solution could be reduced to gain more customers. 

The user interface, mobile application, and support could be improved. Its setup could also be easier.

Siebel CRM can improve as an ERP and for a few corporate business workloads.

In a future release, Siebel CRM should add more connectors and a better GUI to manage the workloads.

The problem with Siebel is that everything is customizable in it. It's probably over-engineered, which makes it difficult to use, and it makes it difficult for the users to get started with the system.

They should provide some guidance on what to customize and what not to customize.
