The operation goals of ALMA science pipeline are: the automated calibration of data taken in standard observing modes, production of science ready images, and the delivery of standard data products to the PI(s) and to the ALMA archive. The ALMA pipeline execution framework is responsible for executing the standard reduction procedure appropriate to each standard observing mode, and generatinga standard set of products including images for that mode. The execution framework must be flexible enough to support observatory pipeline operations, observatory and user reprocessing, commissioning and testing of reduction procedures for new modes, and user desk top reprocessing. This paper outlines the major components of the pipeline execution framework,and describes how they work together within the CASA system to pipeline process ALMA data. Some pipeline results for ALMA Early Science projects are presented to illustrate the role of the execution framework components. Finally the status of the pipeline within current ALMA operations, and its future role in EVLA operations is described.
