8. A computer system for reviewing software source code, the computer system comprising: one or more processors, one or more computer-readable memories, one or more non-transitory computer-readable tangible storage medium, and program instructions stored on at least one of the one or more non-transitory tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising: receiving, by a computer, a changeset object containing information that identifies text changes made to source code statements in a source code module; creating, by the computer, a workflow of the source code module after the text changes identified in the changeset, wherein the workflow identifies execution paths among logical groupings of source code statements in the source code module; identifying, by the computer, logical groupings of source code statements in the workflow that contain text changes identified in the changeset; generating, by the computer, an integrated graphical user interface (GUI) that will: display source code statements in the source code module with a visual indication of the identified text changes; display the workflow with a visual indication of the logical groupings of source code statements in the source code module that contain the text changes identified in the changeset; visually indicate logical groupings in the workflow that contain text changes that are selected by a user in the displayed source code statements; visually indicate source code statements in the displayed source code statements that are contained in a selected logical grouping in the workflow; link comments, entered by the user, that are associated with a source code statement in the displayed source code statements to the logical groupings in the workflow that contain the associated source code statements; link comments, entered by the user, that are associated with a logical grouping in the workflow to the source code statements in the displayed source code statements that contain the associated logical grouping; visually indicate the linked logical groupings when a source code statement in the displayed source code statements is selected; and visually indicate the linked source code statements when a logical grouping in the workflow is selected.

The computer system of claim 8 , wherein the linked comments include specific line comments, general global document comments, added workflow branches and elements, deleted workflow branches and elements, and modified workflow branches and elements.
