For the account manager part, I don't know what could be improved. Everything looks fine. However, for the BPM part, they could improve some user experience or user interface features. We always have problems with the user interface. From version 3.5, we're using the workplace for the application. This was an IBM FileNet application that we were customized and adjusted for the customer. However, they had some private web application toolkit for building this application. It was not very open. We didn't use any other open-source features for improving that application. After that, they had an IBM content navigator, which is very customizable yet not very user-friendly - especially for our developer. The other thing that they could improve is that when you change the workflow definition from the BPM, then when all workflows are started with the older definition there where they have to stay with the older definition and don't see the change for the older workflows. You have to wait for new workflows to start. Changes that you made in the BPM part of the FileNet, especially in the process designer, are not visible for the older workflows, and that's the biggest problem we had besides the user interface. The solution can be quite expensive.
