BTT application grouping

The recommendation is actually not BTT specific, and it can be applied to any J2EE application: avoid packaging and deploying a system as a single WAR/EAR package. Try to break the application into smaller functional groups based on dependencies, function set, development and maintenance groups, etc. Apply the standard J2EE and WebSphere® recommendations on this subject, and consult an expert if required.

Breaking a big project into smaller projects renders it more maintainable, easier to test and administer on the runtime environment, and isolates any failures in the failing subprojects.
