Distribution Performance Measurement (DPM) System is a new reporting system designed to replace the Information Reporting System (IRS) with a more flexible and technologically advanced system. It will be a web-based system that will centralize the reporting function and will support future business reporting needs, free up system resources, reduce 3D capacity constraints and simplify the gathering of information from 3D operational systems. Currently only inbound work-center reports have been released to production. The eventual goal is to replace the IRS system and roll out reports for all the work-centers. DPM is a widely distributed application living at 25+ Distribution Centers (DC)’s and at headquarter (HQ). It will ultimately affect all current IRS users; clericals, techs, IMs, WWs, Execs and HQ.
