Revenue from Contract with Customer [Abstract]
Revenue Recognition	The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on our consolidated balance sheets. Other than contracts with customers with financing arrangements exceeding 12 months, revenue recognition is generally proximal to conversion to cash.
