In a software project, a software vendor is responsible to deliver a piece of software. Everything else, including the infrastructure setup, database and application server installation/configuration/maintenance, etc. are not the responsibility of the software vendor.
Contractually, the software vendor is to provide BCP (business continuity plan) and DRP (disaster recovery plan) documents.
The question is, which sections in these documents are the responsibility of the software vendor? In other words, which parts of the BCP/DRP documents are solely related to the software delivered, rather than the infrastructure setup/installation/configuration/maintenance?
