We use the SRM as a content management tool, to monitor the brand on the social web, and as a reporting tool for our internal reports regarding our social media efforts and the brand on the social web.
At the time we reviewed the services Oracle SRM delivered the full range enterprise package for the most effective cost. I plan to reevlauate after another 6 months to ensure we are still getting the best deal.
The SRM is well suited for organizations that have multiple users working across multiple channels on multiple networks. If you only have a few networks and a single organizational presence on the social web more cost effective solutions are available.
