The Deployment discipline takes care of all artifacts delivered to the end users or customers as well as to the supporting organizations: support, marketing, distribution, and sales.
The Deployment discipline describes the activities associated with beta testing and delivering installable software. Installation can be done by the vendor (in the case of complex, distributed systems) or by the user (in the case of software delivered as a packaged product or over the Internet).
This discipline is highly dependent both on the kind of product being developed and on the business context, and it must be specialized by the organization that is adopting the Rational Unified Process.
