The document discusses Postini's implementation of a custom self-service portal on Salesforce to improve customer service. Key challenges included a need for customization of the default Salesforce support portal and limited customer feedback. The solution included building a custom portal with targeted features, documentation, training registration, and integrated case feedback collection. This resulted in increased training registration tracking, more up-to-date contact data, and higher case feedback rates. The presentation concludes with a roadmap for enhancing the portal with personalization, communities, knowledge base improvements, and additional customization.
