Research and Development [Abstract]
RESEARCH AND DEVELOPMENT	NOTE 18: RESEARCH AND DEVELOPMENT Company-sponsored research and development (“R&D”) costs are expensed as incurred and are included in the “Engineering, selling and administrative expenses” line item in our Consolidated Statement of Income. These costs were $684 million, $329 million, $331 million and $311 million in fiscal 2020, the two quarters ended January 3, 2020, and fiscal 2019 and 2018, respectively. Customer-sponsored R&D costs are incurred pursuant to contractual arrangements, principally U.S. Government-sponsored contracts requiring us to provide a product or service meeting certain defined performance or other specifications (such as designs), and are accounted for principally by the POC cost-to-cost revenue recognition method. Customer-sponsored R&D is included in our revenue and cost of product sales and services.
