Excerpt: A standard Change Control process has been developed for the Standard Economic Processing System (StEPS) to assist managers, system developers, and end users in managing changes to the system software. The purpose of this process is to ensure that: System integrity is maintained Only authorized changes are made Software changes are tested thoroughly Correct versions of software releases are maintained All individuals affected by software changes are notified The Change Control process developed for StEPS adheres to the standards outlined in the ?Economic Directorate Current Surveys Change Control Model?. The process defined in this document replaces an earlier version of the StEPS Change Control process which was released in August, 2001. Changes to the process include a revised Change Control form, a newly defined Change Control Board, and modifications to the Change Approval process.
