This document discusses optimizing process efficiency in a multi-stream data keying environment through co-mingling workstreams. It identifies challenges with decentralized data keying processes, obstacles to change, and how co-mingling processes can improve seat utilization rates and reduce costs. The document presents a case study of J.P. Morgan Treasury Services co-mingling their data keying processes and provides a framework for analyzing current processes, evaluating alternatives, and documenting expected results of optimization efforts.
