1. A computer system for software project modeling using iterative variable defect forecasts, the system comprising: a first microprocessor configured to include a computer forecaster, wherein the computer forecaster is configured to receive and consider point in time analytics from one or more: defect repositories, tracking registries, or test management systems; and the first microprocessor or another microprocessor configured to include a computer Defect Trajectory Modeling (“DTM”) modeler, wherein the DTM modeler is configured to revise a defect trajectory model on an iteration by iteration basis and wherein the DTM modeler is configured to predict schedule deviation for a software programming project.
