Analyst(s): Stefan Van Der Zijden, Jim Duggan, Andy Kyte


Decommissioning an application has two distinct work streams: the implementation of the replacement system and the actual final removal of all traces of the old application, including handling data retention. The latter is a specialist task and needs central management of policies and processes.
