With Cognos Planning - Contributor, organizations can easily engage thousands in the planning process, collecting data from managers and staff across divisions and across geographies. Many users can work simultaneously yet still enjoy rapid server response, because Contributor provides the responsiveness of a spreadsheet, with powerful data collection functionality that spreadsheets can't match. And its user-friendliness increases employee efficiency, buy-in, and commitment to plan. Contributor architecture is easy on technology resources: The client requests data from the server only as needed and saves only data that has changed. Complex calculations are performed at the client, giving users instantaneous response and sparing the server unnecessary traffic during high-use times.
