How Would You Reorganize An Application Service Delivery Model?

Mar 202010

I have been thinking a lot about re-engineering the service delivery model for the application services team that I lead. I have been guiding my team to think about:

“We deliver the platform and work with the business to provide services”.

Our applications team is made up of subgroups aligned by major application services. Here are the major applications:

Business Intelligence
Collaboration Tools
Document Management
Email and Calendaring
ERP (Student, Finance, HR, Doc Mgmt)
Identity Management
Learning Management Applications
Microsoft Applications
Oracle Database
Portal (for students and employees)
SQL Server Database

Currently, there are 3 teams in place in our Business Application Services group. Here are the roles in each team:

Support Team

Oracle DBA
Document Management
Business Intelligence
Project Management
Business Analysis
Identity Management

Email and Collaboration Team

Email
Calendaring
Instant Messaging
Collaboration Platforms
SQL Server DBA
Microsoft Applications
Enterprise Portal

Developer Team

Oracle Developers
Lotus Domino Developers
Microsoft Developers
Java/Web Services Developers

I am interested in hearing from any of you that lead groups with similar responsibilities. Do you have a suggested structure for me to consider? Do you split your team based on roles (technology domains) or by application (vendor) platforms? Do you split operational work from project delivery? Does your governance structure influence your teams organization?

Any suggestions are very welcome and I hope to learn from some of your experiences. Thanks in advance.
