• Product functional capability, categorized into four types:
• To deliver on this vision, there are 2 main components - the Hewitt University Portal, and the Your Development Guide (YDG) application. Portal for associates will deliver both content and functionality. Much of the content will be managed using a content management system, and then delivered via a portal. The YDG application will be a career and development planning tool for associates.
• These portlets has used the Web Service interface available through the Sum Total SDK. There is an authentication framework that is used to establish a session, and then with that session the web services client can make calls through the API to get the required information.
• The primary software components for the portal infrastructure include:
• Execution of analysis, design, implementation, documentation, testing, and maintenance tasks as part of ongoing strategic and operational initiatives
• Supporting the efforts of the Hewitt Service Operations (HR processing & Finance) team as needed; applying team-defined best practices, including testing and documentation, in all team project work
